In Bandl-Konrad Motion 3 (Paper 31), Bandl-Konrad argues that Claims 10-
13, 19, 20, 28, 31, 32, 34, 34, and 46-49 of Gandhi’s involved application Serial
No. 12/706,558 are unpatentable under 35 U.S.C. § 112, first paragraph, for lack of
written description support from Gandhi’s involved application. However, Bandl-
Konrad does not challenge Gandhi’s independent Claims 9, 30, and 33. 5
In Bandl-Konrad Motion 4 (Paper 32), Bandl-Konrad argues:
 Claims 9 and 46 of Gandhi’s involved application are
unpatentable under 35 U.S.C. §§ 102 and 103 as being
anticipated or rendered obvious over Kinugasa, U.S. Patent No.
6,109,024 (Kinugasa ‘024; Ex. 2004); 10

 Claims 19, 30, 32, 33 and 35 of Gandhi’s involved application
are unpatentable under 35 U.S.C. § 102(b) as being anticipated
by Kinugasa ‘024 (Ex. 2004);
15
 Claims 10, 31, 34 and 47 of Gandhi’s involved application are
unpatentable under 35 U.S.C. § 103(a) as rendered obvious
over Kinugasa ‘024 (Ex. 2004) and Twigg, PCT International
Application No. 00/21647 (Twigg ‘647; Ex. 2013); and
20
 Claims 48-49 of Gandhi’s involved application are unpatentable
under 35 U.S.C. § 103(a) as rendered obvious over Kinugasa
‘024 (Ex. 2004).

In Gandhi Substantive Motion 1 (Paper 26), Gandhi argues: 25
 Claim 9 of Bandl-Konrad ‘747 patent is unpatentable under 35
U.S.C. § 102(e) as being anticipated by U.S. Patent Application
Publication No. 2004/0076565 (Ex. 1005) (now issued as U.S.
Patent No. 7,332,135), the grandfather of Gandhi’s involved
application, (hereinafter referred to as Gandhi ‘470 30
application
1
);

1
Gandhi ‘470 application published on April 22, 2004 with an earlier U.S. filing
date of October 22, 2002, and as such, qualifies a prior art under 35 U.S.C. §102(e)
against Bandl-Konrad ‘747 patent.
4

 Claims 11-15 and 18 of Bandl-Konrad ‘747 patent are
unpatentable under 35 U.S.C. § 103(a) as rendered obvious
over Gandhi ‘470 application in view of a skilled artisan
knowledge as represented by Kolmanvosky, U.S. Patent No.
6,347,512 (‘Kolmanvosky ‘512) (Ex. 1012); Kaneko, U.S. 5
Patent No. 7,127,883 (Kaneko ‘883; Ex. 1013); and Andreasson
WO 99/39809 (Andreasson ‘809; Ex. 1008);

 Claims 1, 4, 5, 7 and 10 of Bandl-Konrad ‘747 patent are
unpatentable under 35 U.S.C. § 103(a) as rendered obvious 10
over Gandhi ‘470 application in view of Khair, U.S. Patent No.
6,293,096 (Khair ‘096; Ex. 1006); and

 Claims 2, 3, 6, 8, 16, 17 and 19 of Bandl-Konrad ‘747 patent
are unpatentable under 35 U.S.C. § 103(a) as rendered obvious 15
over Gandhi ‘470 application, Khair ‘096 and in view of a
skilled artisan knowledge as represented by other prior art
references.

We exercise our discretion under 37 C.F.R. § 41.125(a) to take up these 20
motions in the following order (Berman v. Housey, 291 F.3d 1345, 1352 (Fed. Cir.
2002); 37 C.F.R. § 41.125(a)):
(1) Bandl-Konrad Motion 3 (Paper 31) to address an alleged
lack of “written description” under 35 U.S.C. § 112, first paragraph;
25
(2) Bandl-Konrad Motion 4 (Paper 32) to account for an
alleged lack of patentability of any Gandhi Claims that are fully
supported by a written description in the original specification of
Gandhi’s involved application and that survive Bandl-Konrad Motion
3 (Paper 31); and 30

(3) Gandhi Motion 1 (Paper 26) to account for an alleged
lack of patentability of Bandl-Konrad Claims 1-19.

Claims 9-13, 19, 20, 28, 30-35 and 46-49 of Gandhi’s Involved Application 35
As discussed below, the preponderance of the evidence leads us to find that
Bandl-Konrad has shown that Gandhi’s Claims 11-13 and 20 as presented in
5

Bandl-Konrad Motion 3 (Paper 31) are unpatentable under 35 U.S.C. § 112, first
paragraph, for lack of written description support from Gandhi’s involved
application. However, we find that Gandhi’s remaining Claims 9, 10, 19, 28, 30-
35, and 46-49 (including unchallenged Claims 9, 30, and 33) have not been shown
to lack written description support in the original specification of Gandhi’s 5
involved application.
Nevertheless, we find that Bandl-Konrad has shown that Gandhi’s remaining
Claims 9, 10, 19, 28, 30-35, and 46-49 as presented in Bandl-Konrad Motion 4
(Paper 32) are unpatentable under 35 U.S.C. §§ 102 and 103 over prior art,
including Kinugasa ‘024 and Twigg ‘647. Accordingly, we hold that all of Gandhi 10
Claims 9-13, 19, 20, 28, 30-35, and 46-49 of Gandhi’s involved application are
unpatentable under 35 U.S.C. §§ 102, 103, and 112, 1
st
paragraph.

Claims 1-19 of Bandl-Konrad ‘747 Patent
For the reasons detailed below, we find that Bandl-Konrad has not rebutted 15
the presumption under 37 C.F.R. §41.207(c) regarding Claims 9, 11-14, and 18 of
Bandl-Konrad ‘747 patent. As such, we hold that Claims 9, 11-14, and 18 of
Bandl-Konrad ‘747 patent are unpatentable under 35 U.S.C. §§ 102 and 103 over
the same prior art cited in Bandl-Konrad Motion 4 (Paper 32). As a result, we only
need to address remaining Claims 1-8, 10, 15-17, and 19 of Bandl-Konrad ‘747 20
patent as presented in Gandhi Substantive Motion 1 (Paper 26).
As discussed below, the preponderance of evidence leads us to find that
Gandhi has not shown that Claims 1-8, 10, 16-17, and 19 of Bandl-Konrad ‘747
patent are unpatentable under 35 U.S.C. §§ 102 and 103 over prior art, including
Gandhi ‘470 application and Khair ‘096. However, Gandhi has shown that Claim 25
15 of Bandl-Konrad ‘747 patent is unpatentable over Gandhi ‘470 application,
6

Khair ‘096 and Pieplu Article. Accordingly, we hold that Claims 9, 11-15, and 18
of Bandl-Konrad ‘747 patent are unpatentable under 35 U.S.C. §§ 102 and 103.

Summary of Decisions on Motions
(1) Bandl-Konrad Motion 3 (Paper 31) is GRANTED as to Gandhi 5
Claims 11-13 and 20, and is otherwise DENIED as to Gandhi Claims 10, 19, 28,
31, 32, 34, 35, and 46-49.
(2) Bandl-Konrad Motion 4 (Paper 32) is GRANTED as to Gandhi’s
remaining Claims 9-10, 19, 28, 30-35, and 46-49. We need not reach the merits of
the motion with respect to Gandhi Claims 11-13 and 20 as these claims were held 10
unpatentable as a result of Bandl-Konrad Motion 3 (Paper 31).
(3) Bandl-Konrad Claims 9, 11-14, and 18 of Bandl-Konrad ‘747 are
unpatentable by operation of the presumption of 37 C.F.R. § 41.207(c). Bandl-
Konrad has failed to show that Claims 9, 11-14, and 18 are not unpatentable over
the prior art cited against Gandhi Claims 9-10, 19, 28, 30-35, and 46-49 in Bandl-15
Konrad Motion 4 (Paper 32).
(4) Gandhi Substantive Motion 1 (Paper 26) is GRANTED as to Bandl-
Konrad Claim 15 of Bandl-Konrad ‘747, and is otherwise DENIED as to Bandl-
Konrad Claims 1-8, 10, 16, 17 and 19.
As a result of the above decisions, Gandhi has no patentable claims and 20
Bandl-Konrad Claims 1-8, 10, 16, 17 and 19 have not been shown to be
unpatentable. Because there currently is no basis for formulating a count
representing the common patentable subject matter of the parties, it is appropriate
to terminate the interference at this point. Consequently, we need not reach
Bandl-Konrad Motion 1 (Paper 29) to substitute new Count and Bandl-Konrad 25
contingent Motion 2 (Paper 30) to re-designate claims corresponding to the
7

substituted new Count. Therefore, Bandl-Konrad Motion 1 (Paper 29) and Bandl-
Konrad contingent Motion 2 (Paper 30) are DISMISSED.

II. BACKGROUND

III. BANDL-KONRAD MOTION 3 (PAPER 31) SEEKING ENTRY OF 10
JUDGMENT AGAINST GANDHI BASED ON AN ALLEGED LACK OF A
WRITTEN DESCRIPTION UNDER 35 U.S.C. § 112, ¶1

In Bandl-Konrad Motion 3 (Paper 31), Bandl-Konrad asserts that Claims 10-
13, 19, 20, 28, 31, 32, 34, 35, and 46-49 of Gandhi’s involved application, which 15
represent almost all of Gandhi’s claims involved in this interference (except for
independent Claims 9, 30, and 33)
7
are unpatentable under 35 U.S.C. § 112, first
paragraph, for lack of written description in the original specification of Gandhi’s
involved application, U.S. Patent Application Serial No. 12/706,558. Claims 11,
19, and 46 are independent claims, and the remainder claims are dependent. 20
Below are our findings of facts, analysis and conclusion of law regarding written
description support from Gandhi’s involved application for each of the contested
Claims 10-13, 19, 20, 28, 31, 32, 34, 35, and 46-49 of Gandhi’s involved
application.

7
Bandl-Konrad has not contested the written description support for Gandhi’s
Claims 9, 30, and 33. As such, Gandhi’s Claims 9, 30, and 33 are presumed to
have written description support from the specification of Gandhi’s involved
application.
10

A. Findings of Facts
We make the following findings of facts (“FFs”) to resolve issues presented
in Bandl-Konrad Motion 3 (Paper 31). These FFs, as well as others made
elsewhere in the Opinion, are supported by at least a preponderance of the
evidence on the record. Ethicon, Inc. v. Quigg, 849 F.2d 1422, 1427 (Fed. Cir. 5
1988).
1. The terms “nitrogen oxide storage catalytic converter,” “NOx absorber
catalytic converter,” “NOx trap,” “lean NOx trap,” “LNT” and “lean NOx
absorber” as used in Gandhi’s involved application, U.S. Patent
Application Serial No. 12/706,558 (Gandhi ‘558 application;
8
Ex. 1025), 10
and its earlier grandparent U.S. Patent Application Serial No. 10/065,470
(Gandhi ‘470 application;
9
Ex. 1005), as well as Bandl-Konrad’s
involved patent (‘747 patent, Ex. 1003) are interchangeable and refer to
the same catalytic technology that, among other things, operates in a
cyclical fashion storing NOx during lean conditions (lean mode of 15
operation) and reducing NOx during rich conditions (rich mode of
operation).
10

2. The terms “SCR catalytic converter” and “NH3-SCR catalyst” as used in
Gandhi’s involved application (Gandhi ‘558 application), and its earlier

8
Gandhi’s involved application (Gandhi ‘558 application) is relied upon to
support Bandl-Konrad Motion 3 (Paper No. 31) to determine whether Gandhi
Claims 10-13, 19, 20, 28, 31, 32, 34, 35, and 46-49 are unpatentable under 35
U.S.C. § 112, 1
st
paragraph.
9
In contrast, Gandhi ‘470 application is relied upon to support Gandhi Substantive
Motion 1 (Paper 26) to determine whether Bandl-Konrad Claims 1-19 are
patentable under 35 U.S.C. §§ 102 and 103.
10
See Declaration of Oliver Krӧcher, Ph.D., in support of Bandl-Konrad Motion 3
(Paper 31), Ex. 2009, ¶25; Declaration of Michael Harold, Ph.D., in support of
Gandhi Motion 3 (Paper 31), Ex. 1030, ¶55; Ex. 2014, ¶58.
11

grandparent, Gandhi ‘470 application, as well as the Bandl-Konrad’s
involved patent (‘747 patent, Ex. 1003) are interchangeable and refer to
the same technology.
11

3. The terms “lean exhaust gas air ratio,” “lean-burn conditions,” “lean
cycles” and “lean conditions” refer to the same operating conditions.
12
5
4. Likewise, the terms “rich exhaust gas air ratio,” “rich-burn conditions,”
“rich cycles” and “rich conditions” refer to the same operating
conditions.
13

5. The term “oxidation catalytic converter” contained in Gandhi’s Claim 11
and “oxidizing catalytic converter” contained in Gandhi’s Claim 19 are 10
interchangeable.
6. A “three-way” catalytic converter is an oxidizing or oxidation catalytic
converter. Ex. 1017, col. 1, ll. 40-43.

Gandhi’s Involved Application (Gandhi ‘558 Application) 15
7. Gandhi ‘588 application discloses a catalyst system, as shown in Fig. 2,
capable of simultaneously eliminating ammonia emissions and improving
net NOx conversion. Ex. 1025; Gandhi ‘558 application, ¶[0033]. Fig. 2
is reproduced below.

11
See Declaration of Michael Harold, Ph.D., in support of Gandhi Substantive
Motion 1 (Paper 26), Ex. 1030, ¶56; Ex. 2014, ¶70.
12
Id., ¶57.
13
Id., ¶58.
12

As shown in Fig. 2, the catalyst system includes a lean NOx trap and
an NH3-SCR catalyst. As expressly described by Gandhi ‘558
application:
“The advantage of the catalyst system of this invention is 5
the use of a combination of a lean NOx trap and an NH3-
SCR catalyst. The use of a lean NOx trap in the present
system allows for much greater storage of NOx, because
the NOx breakthrough that would otherwise happen can
be controlled by the NH3-SCR catalyst. Additionally, the 10
use of a lean NOx trap as part of this system allows for
the operation of the engine at lean conditions for a longer
time, and thus provides improved fuel economy . . . .
Thus the combination of a lean NOx trap and NH3-SCR
catalyst allows for significant NOx storage and ammonia 15
production and thus increases net NOx conversion.”

Ex. 1025; Gandhi ‘558 application, ¶[0045] (emphasis added).
8. In a preferred embodiment of Gandhi ‘558 application, the combination
of a lean NOx trap and an NH3-SCR catalyst (shown in Fig. 2) is 20
implemented as adjacent or alternating lean NOx trap and NH3-SCR
catalyst zones arranged on a single substrate or a single catalytic
converter can, as shown in Figs. 4a-4c (reproduced below).
13

Ex. 1025; Gandhi ‘558 application, ¶¶[0046]-[0048]; Figs. 4a-4c.
9. In another preferred embodiment of Gandhi’s involved application, the
combination of a lean NOx trap and an NH3-SCR catalyst (as shown in
Fig. 2) is implemented as a lean NOx trap washcoat and an NH3-SCR 5
washcoat applied to a single substrate, as shown in Figs. 7a-7c
(reproduced below).

As shown in Figs. 7a-7b, the lean NOx trap washcoat and NH3-SCR
washcoat are formed on the bottom and top layer of a substrate, 10
respectively. In contrast, Fig. 7c involves the use of a one layer washcoat
containing both lean NOx trap and NH3-SCR washcoat formulations. Ex.
1025; Gandhi ‘558 application, ¶¶[0052]-[0053]; Figs. 7a-7c.
14

10. In the context of the washcoat arrangement shown in Figs. 7a-7c, Gandhi
‘558 application also describes that:
“The invention also contemplates engineering such
combinations within the pores of the monolithic
substrate. An example of this is incorporating washcoat 5
into porous substrates used for filtering diesel particulate
matter. Thus, this lean NOx trap/NH3-SCR catalyst
concept can be integrated into diesel particulate matter
devices.”
10
Ex. 1025; Gandhi ‘558 application, ¶[0054] (emphasis added).
11. In an alternative embodiment of Gandhi ‘558 application, “three-way”
catalysts are also utilized to improve net NOx conversion, eliminate NH3
emissions and reduce catalyst costs, shown in Fig. 9 (reproduced below).
15
12. The three-way catalytic converter can be located upstream of the
NOx/NH3-SCR system. Ex. 1025; Gandhi ‘558 application, ¶[0038].
13. As shown in Fig. 9, a first three-way catalyst 14 is positioned in close
proximity to the engine 12 to reduce cold start emissions; a second three-
way catalyst 16 is modified to enhance the ability of the second three-20
way catalyst 16 to generate NH3 emissions; and an NH3-SCR catalyst 18
is arranged downstream of the second three-way catalyst 16 to store NH3
produced for reaction with NOx emissions in order to reduce both NOx
and NH3 emissions. In other words, a three-way catalyst 14 can be
15

disposed upstream of a lean NOx trap/NH3-SCR system. Ex. 1025;
Gandhi ‘558 application, ¶[0061].
14. In view of FFs. 6 and 11-13, Gandhi describes an oxidation catalytic
converter as the first exhaust gas aftertreatment component and therefore
discloses an oxidizing catalytic converter as the first exhaust gas 5
aftertreatment component.

Bandl-Konrad ‘747 Patent
15. Bandl-Konrad ‘747 patent discloses an exhaust gas aftertreatment
installation and associated exhaust gas aftertreatment (purification) 10
method of an exhaust gas generated by an internal combustion engine
using a nitrogen oxide storage catalytic converter (also known as NOx
storage catalytic converter or NOx absorber catalytic converter (“NSC”))
and an SCR catalytic converter with the ability to store ammonia. Ex.
2001; Bandl-Konrad ‘747 patent, col. 1, ll. 16-35. 15
16. In order to increase the efficiency of the SCR catalytic converter, Bandl-
Konrad ‘747 discloses a NO2 producing catalytic converter arranged
upstream of the SCR catalytic converter. Ex. 2001; Bandl-Konrad ‘474
patent, col. 5, ll. 25-27.
17. In addition, a particulate filter is arranged upstream of the SCR catalytic 20
converter and downstream of the NO2 producing catalytic converter to
retain the particulates emitted. Ex. 2001; Bandl-Konrad ‘474 patent, col.
3, ll. 31-34; col. 4, ll. 59-64; col. 6, ll. 10-21.
18. A further oxidation catalytic converter can also be connected upstream of
the NOx storage catalytic converter, i.e., positioned as a first exhaust gas 25
purification component relative to an engine, in order to lower the
emissions of hydrocarbons (HC) and carbon monoxide (CO) during cold
16

starts. Ex. 2001; Bandl-Konrad ‘747 patent, col. 16, ll. 14-18; col. 9, ll.
5-8.
19. According to Bandl-Konrad ‘747 patent,
“Various possible implementations are possible for the
order in which the NOx storage catalytic converter, SCR 5
catalytic converter, particulate filter and NO2-producing
catalytic converter are arranged in the exhaust train, each
of these implementations having specific properties and
advantages; the options include multi-flow
arrangements.” 10

Ex. 2001; Bandl-Konrad ‘747 patent, col. 7, ll. 41-46 (emphasis added).
20. Bandl-Konrad ‘747 patent describes that:
“Fig. 4 shows a further variant, in which the exhaust gas
aftertreatment installation has a combined SCR and 15
nitrogen oxide storage catalytic converter 15 ...”

Ex. 2001; Bandl-Konrad ‘747 patent, col. 17, ll. 25-27 (emphasis added).
In other words, a combined nitrogen oxide storage and SCR catalytic
converter 15 performs the functions of the NOx storage catalytic 20
converter 6 and the SCR catalytic converter 7, as described in connection
with Figs. 1-3 of Bandl-Konrad ‘747 patent.
21. Bandl-Konrad ‘747 patent further describes that:
“Instead of being arranged upstream of the particulate
filter 5, the NO2-producing catalytic converter 13 may 25
also be integrated at the outlet end of the NOx storage
catalytic converter 6.... As a further possible option, it is
also possible for the NO2-producing catalytic converter
13 to be integrated at the inlet end of the SCR catalytic
converter 7. Alternatively, the NO2 producing catalytic 30
converter 13 can also be dispensed with altogether.”

Ex. 2001; Bandl-Konrad ‘747, col. 16, ll. 4-13 (emphasis added). In
other words, the separate NO2-producing catalytic converter 13, as shown
17

in Fig. 2, can be integrated at the outlet end or the inlet end of the SCR
catalytic converter 7. This way the SCR catalytic converter 7 can also
perform the function of the NO2-producing catalytic converter 13.
22. In addition, Bandl-Konrad ‘747 patent also describes that:
“If appropriate, the SCR catalytic converter as a 5
separate component can also be dispensed with
altogether. In this case, the temperature sensor 8
illustrated in FIG. 2 between particulate filter and SCR
catalytic converter can be dispensed with, but the
pressure sensor 14 illustrated downstream of the 10
particulate filter is retained.”

Ex. 2001; Bandl-Konrad ‘747 patent, col. 15, l. 64 – col. 16, l. 3
(emphasis added).
23. Bandl-Konrad ‘747 patent also describes that: 15
“If appropriate, it is also possible for the separate NOx
storage catalytic converter 6 to be dispensed with
altogether, i.e. for its function to be integrated in the
particulate filter 5. In this case, it is also possible for
both the NO2-producing catalytic converter 13 and the 20
device 11 for supplying reducing agent downstream of
the engine and upstream of the NO2-producing catalytic
converter 13 to be dispensed with.”

Ex. 2001; Bandl-Konrad ‘747 patent, col. 15, ll. 49-56 (emphasis 25
added). In other words, the separate NOx storage catalytic
converter 6, as shown in Fig. 2, can be integrated in the particulate
filter 5. This way the particulate filter 5 can also perform the
function of the NOx storage catalytic converter 6.
24. Fig. 2 of Bandl-Konrad ‘747 patent, which we reproduce below, 30
discloses exhaust gas aftertreatment components connected in series and
arranged in a particular order, such as: (1) a nitrogen oxide (NOx) storage
18

catalytic converter 6, (2) a particulate filter 5, (3) an SCR catalytic
converter 7, and (4) an oxidation catalytic converter 4.

Ex. 2001; Bandl-Konrad ‘747 patent, col. 14, ll. 22-31; Fig. 2.
25. Fig. 6 of Bandl-Konrad ‘747 patent (annotated and reproduced below) 5
discloses an embodiment shown in Fig. 2, but with an oxidation catalytic
converter arranged as a first exhaust aftertreatment component, as seen in
the direction of flow of the exhaust gas.

Ex. 2001; Bandl-Konrad ‘747 patent, col. 16, ll. 14-18; Fig. 6 10
(annotated).
26. According to Bandl-Konrad ‘747 patent, certain components shown in
connection with Figs. 2 and 6 (as well as other figures), including
19

temperature sensors 8, NOx sensors 9, pressure sensors 14, device 11 for
supplying reducing agent downstream of an engine, and device 12 for
supplying air and pressure sensors 14, can be combined or integrated in
order to reduce the overall space taken up.
27. In view of FFs. 19-26, Bandl-Konrad ‘747 patent describes both (1) 5
separate and distinct and (2) integrated components as alternatives.

B. Analysis.
1.
As an initial matter, we reject Bandl-Konrad’s approach to challenging 10
Gandhi’s claims on written description grounds. Bandl-Konrad argues that “for
Gandhi to be entitled to the benefit of the October 22, 2002, filing date of [Gandhi
Application 10/065,470], Gandhi must show that the specification for the Gandhi
‘470 application (Ex. 2008) discloses the claimed subject matter in Gandhi’s
involved application.” Paper 31, p. 2, ll. 15-18. However, the only appropriate 15
specification for the determination of adequate written descriptive support is the
specification in which the involved claims form a part, Application 12/706,558.
See Reiffin v. Microsoft Corp., 214 F.3d 1342, 1346 (Fed. Cir. 2000). However,
because Gandhi ‘558 application is said to be a continuation of Application
12/325,787 which is said to be a continuation of Gandhi ‘470 application, we will 20
presume that the written description of Gandhi’s involved application is identical
to that of Gandhi ‘470 application. References in the party’s papers and in
testimony referring to Gandhi ‘470 application are considered to be references to
Gandhi’s involved application. The citations and references to Gandhi’s
application, specification, written description or claims in this opinion are 25
references to those as filed on February 16, 2010.
20

Second, Bandl-Konrad characterizes that only Claims 11-13, 19, 20, and 28
of Gandhi’s involved application were copied from Bandl-Konrad ‘747 patent, and
thus, only Gandhi Claims 11-13, 19, 20, and 28 must be interpreted in the context
of the specification of Bandl-Konrad ‘747 patent for purposes of determining
compliance with the written description requirement of 35 U.S.C. § 112, first 5
paragraph.
14
Agilent Tech., Inc. v. Affymetrics, Inc., 567 F.3d 1366, 1375 (Fed.
Cir. 2009) (“[W]hen a party challenges a written description for the interference
count or the copied claim in an interference, the originating disclosure provides the
meaning of the pertinent claim language”). Paper 48, p. 2, ll. 7-10. However,
Bandl-Konrad’s characterization is incorrect and inconsistent with the prosecution 10
history of Gandhi’s involved application. In particular, in an Amendment filed
February 14, 2011 filed in Serial No. 12/706,558, Gandhi Claim 19 was copied
from Bandl-Konrad ‘747 patent and is identical to Claim 9 of Bandl-Konrad ‘747
patent. However, all Gandhi remaining Claims 9-13, 20, 28, 30-35 and 46-49 were
said to be substantially copied from Bandl-Konrad ‘747 patent and are similar, 15
albeit different in scope than Claim 9 of Bandl-Konrad ‘747 patent. See
Amendment, p. 12. We are aware of no reason that would justify treating
identically copied and substantially copied claims differently. As such, and for
purposes of Agilent, all Gandhi “copied” claims, i.e., Claims 9-13, 19-20, 28, 30-
35 and 46-49 shall be treated as “copied” claims, and shall be interpreted in the 20
context of Bandl-Konrad’s disclosure as discussed herein below.

2.
In order to satisfy the written description requirement under 35 U.S.C. §
112, first paragraph, the specification must convey with reasonable clarity to those 25

14
See Gandhi’s Request for Interference filed August 1, 2011 and Amendment
filed February 14, 2011.
21

of ordinary skill in the art that as of the filing date of the application the inventor
disclosed the claimed invention. Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563-
64 (Fed. Cir. 1991); see also Pandrol USA, LP v. Airboss Ry. Products, Inc., 424
F.3d 1161, 1165 (Fed. Cir. 2005). The purpose of the written description
requirement is to prevent applicants from later asserting that they invented that 5
which they did not. Amgen Inc. v. Hoechst Marion Roussel Inc., 314 F.3d 1313
(Fed. Cir. 2003). However, the description does not have to be in the exact same
words, in ipsis verbis, as the language at issue in the corresponding claim. In re
Wertheim, 541 F.2d 257, 265 (CCPA 1976); In re Lukach, 442 F.2d 967, 969
(CCPA 1971). Equally true is that obviousness is not the test for written 10
description. In other words, a description that simply renders obvious a claimed
invention is not sufficient to satisfy the written description requirement. Lockwood
v. American Airlines Inc., 107 F.3d 1565 (Fed. Cir. 1997). The question is whether
the written description objectively tells the person of ordinary skill that the
inventor contemplated the subject matter now claimed. 15
The status quo of an interference is presumed correct. A party wishing to
change the status quo may be authorized to file a substantive motion under 37
C.F.R. §41.212(a) to effect that change. As the moving party, Bandl-Konrad bears
the burden of proof to demonstrate entitlement to the relief requested. 37 C.F.R. §
41.121(b). To be sufficient, a motion must provide a showing, supported with 20
appropriate evidence, such that, if unrebutted, it would justify the relief sought. 37
C.F.R. § 41.208(b). The applicable standard of proof is by a preponderance of the
evidence. Bosies v. Benedict, 27 F.3d 539, 541-42 (Fed. Cir. 1994).

3. 25
Bandl-Konrad has identified four limitations of Gandhi’s Claims 10-13, 19,
20, 28, 31-35, and 46-49 said not to be described by Gandhi’s written description:
22

(1) separate and distinct exhaust gas aftertreatment components; (2) an oxidation
catalytic converter as the first exhaust gas after treatment component; (3)
increasing the amount of NO2 in the exhaust gas using a catalytic converter
upstream of the SCR catalytic converter; and (4) a particulate filter located after
the nitrogen oxide storage catalytic converter and before the SCR catalytic 5
converter. Paper 31, pp. 6-14.

1) Separate and Distinct Exhaust Gas Aftertreatment Components

Claims 10-13, 19, 20, 28, 31-35, and 46-49 10
In Bandl-Konrad Motion 3 (Paper 31), Bandl-Konrad, relying on testimony
of its expert, Dr. Oliver Krӧcher, asserts that the four specified exhaust gas
purification (aftertreatment) components of the parties’ claims should be construed
as separate and distinct components that exclude integrated or combined
components. Paper 31, page 6; Ex. 2009, ¶57. 15
Citing Agilent, 567 F.3d at 1376, Bandl-Konrad argues that Gandhi’s Claims
10-13, 19, 20, 28, 31-35, and 46-49 (all but Claims 9, 30 and 33 of Gandhi’s
involved application) were copied from Bandl-Konrad’s patent and therefore must
be construed in light of Bandl-Konrad’s written description. When read in light of
Bandl-Konrad’s disclosure, Bandl-Konrad contends that its written description 20
compels a construction that excludes combined or integrated components.
We disagree. Pending claims in interference proceedings are given their
broadest reasonable construction in a manner consistent with Agilent, i.e., in light
of Bandl-Konrad’s disclosure. Claim terms are also accorded their ordinary and
accustomed meaning as would be understood by one of ordinary skill in the art. 25
Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005) (en banc). In some
cases, as here, the ordinary meaning of claim language as understood by a person
of skill in the art may be readily apparent even to lay judges, and claim
23

construction in such cases involves little more than the application of the widely
accepted meaning of commonly understood words. Phillips v. AWH Corp., 415
F.3d at 1314. This means that the words of the claims are given their plain
meaning unless that meaning is inconsistent with the specification. In re Zletz, 893
F.2d 319, 321 (Fed. Cir. 1989). Consequently, care must be exercised as there is 5
an important distinction between interpreting claims in light of the specification
and reading limitations into the claims from the specification. Comark Commc'ns,
Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998). Limitations appearing
in the specification but not recited in the claim must not be read into the claim. E-
Pass Techs., Inc. v. 3Com Corp., 343 F.3d 1364, 1369 (Fed. Cir. 2003) (claims 10
must be interpreted “in view of the specification” without importing limitations
from the specification into the claims unnecessarily.)
At the outset, we note that there is no language in any of the Gandhi claims
that expressly requires the components to be separate and distinct from each other.
The plain language of Gandhi claims simply does not require the four exhaust gas 15
aftertreatment components be “separate” or “distinct” from each other; rather,
Gandhi claims simply require various components arranged in a specific order in
relation to each other and the exhaust gas flow.
This plain interpretation of Gandhi claims is consistent with Bandl-Konrad’s
disclosure, since Bandl-Konrad’s disclosure is also not limited to separate and 20
distinct components. In fact, Bandl-Konrad discloses that exhaust gas components
can be combined or integrated together. For example, Bandl-Konrad describes
that:
“Fig. 4 shows a further variant, in which the exhaust gas
aftertreatment installation has a combined SCR and 25
nitrogen oxide storage catalytic converter 15 ...”

24

Ex. 2001; Bandl-Konrad ‘747, col. 17, ll. 25-27; FFs. 15-20 (emphasis added).
Bandl-Konrad’s disclosure further teaches that:
“Instead of being arranged upstream of the particulate
filter 5, the NO2-producing catalytic converter 13 may
also be integrated at the outlet end of the NOx storage 5
catalytic converter 6.... As a further possible option, it is
also possible for the NO2-producing catalytic converter
13 to be integrated at the inlet end of the SCR catalytic
converter 7.”
10
Ex. 2001; Bandl-Konrad ‘747, col. 16, ll. 4-13; FFs. 20-17 (emphasis added).
Thus, in the absence of express limiting claim language, there is no basis to
construe Bandl-Konrad’s invention as excluding integrated components.
Accordingly, Bandl-Konrad’s written description does not support construing
Gandhi’s copied claims as excluding integrated or combined components. 15
Even assuming arguendo that Bandl-Konrad's claims are limited to separate
and distinct components, Bandl-Konrad has failed to establish that Gandhi’s
written description does not support separate and distinct components.
Bandl-Konrad relies on the testimony of Dr. Krӧcher to establish that
Gandhi’s written description should be construed as only describing integrated or 20
combined components. In particular, Dr. Krӧcher proffers two reasons why one
skilled in the art would consider Gandhi’s written description to exclude combined
or integrated components: (1) the claims separately recite four components having
a particular relationship with each other, and (2) Gandhi’s involved application
only discloses integrating filtering particulates with a nitrogen oxide storage 25
catalytic converter and an SCR catalytic converter. Ex. 2009, ¶¶57-58.
We do not consider Dr. Krӧcher’s testimony to be probative on these points.
While the claim language requires that the components have a certain physical
relationship to each other, neither the Bandl-Konrad’s motion nor Dr. Krӧcher’s
25

testimony adequately explains why the claim language excludes combined or
integrated components. As previously noted, the claim language itself is totally
silent on whether the components are combined, or alternatively, are separate and
distinct. All the claim language expressly requires is that the exhaust gases flow
through the components in a required order. 5
Dr. Krӧcher has not explained why the structures disclosed, for example, in
Gandhi’s Figures 2, 4a and 9, and their accompanying textual descriptions, do not
convey to a person skilled in the art the use of separate and distinct components.
Each of Gandhi’s Figures 2, 4a and 9 shows components which appear to be
separate and distinct from the others. For example, Fig. 4a shows a lean NOx trap 10
(LNT) as separate and distinct from an SCR catalyst. Ex. 2002, Figs. 2, 4a and 9;
FFs. 7-14. Each of these components separately and distinctly performs its
designed functions.
Dr. Krӧcher’s second point is directed to Gandhi’s disclosure of a combined
particulate filter, nitrogen oxide storage catalytic converter and SCR catalytic 15
converter. We simply do not see, and Dr. Krӧcher has not adequately explained,
how Gandhi’s discussion of this optional feature (Ex. 1005, ¶¶[0052]-[0053])
conveys that Gandhi teaches that all the other components would be understood
only to be integrated or combined components.
For these reasons, Bandl-Konrad has not met its burden of establishing that 20
its written description and claims are limited to describing “separate” and
“distinct” components or that Gandhi’s written description is limited to combined
or integrated components.

26

2) An Oxidation Catalytic Converter as the First Exhaust Gas
Aftertreatment

Claims 11, 19, and 46
Claims 11 and 19 further recite “an oxidation catalytic converter arranged as 5
a first exhaust gas aftertreatment component, as seen in the direction of flow of the
exhaust gas.” Ex. 2002, Claims 11 and 19. Gandhi Claim 46 is similar to Claims
11 and 19, except that a generic “catalyst capable of oxidizing” is recited instead of
“an oxidizing catalytic converter” as recited in Gandhi Claims 11 and 19. Ex.
2002, Claim 46. 10
Bandl-Konrad relies on Dr. Krӧcher’s testimony, and argues that Gandhi
does not have a written description of an oxidation catalyst as the first exhaust gas
aftertreatment component as seen in the direction of the flow of the exhaust gas:
Dr. Krӧcher found no support in Gandhi’s involved application
for this particular arrangement of the oxidation catalytic 15
converter. Ex. 2009, ¶ 66. In fact, according to Dr. Krӧcher,
Gandhi’s involved application leaves open the possibility that
other exhaust gas treatment components can be arranged in
front of the oxidation catalytic converter. Ex. 2009, ¶ 66.
20
Paper 31, p. 8, ll. 14-18.
We have reviewed Dr. Krӧcher’s testimony and do not consider it to be
probative on features of Gandhi Claims 11, 19, and 46.
First, we find Dr. Krӧcher’s testimony, that Gandhi’s written description
leaves open the possibility that other exhaust gas treatment components can be 25
arranged in front of the oxidation catalytic converter, not to be relevant. The
specific question is whether Gandhi’s written description teaches an oxidation
catalytic converter as the first exhaust gas aftertreatment. The fact that Gandhi
left open, or even expressly disclosed, that other exhaust treatments could also be
27

the first component, does not establish that the written description does not also
disclose an oxidation catalyst to be the first after treatment.
We have reviewed Gandhi’s disclosure and have identified a number of
portions relevant to the location of the oxidation catalytic converter. In addition to
the lean NOx trap (LNT) and the SCR catalyst converter, Gandhi describes the use 5
of three-way catalysts. A three-way catalyst oxidizes hydrocarbons and carbon
monoxide as well as NOx. Ex. 1005, ¶[0002]; Ex. 1017, col. 1, ll. 40-43; Ex.
1025, ¶[0002]; FFs. 7-14. Thus, a three-way catalyst is seen as an oxidation
catalytic converter. Gandhi teaches that a three-way catalyst may be used in
conjunction with a lean NOx trap and NH3-SCR catalyst (Ex. 1005, ¶[0061]), that 10
a three-way catalyst may be used to generate ammonia upstream of the LNT/
NH3-SCR system (¶[0038]) and Figure 9 shows a three-way catalyst 14 located as
the first exhaust gas after treatment component (¶[0059]). Dr. Krӧcher’s
testimony does not address all the above-cited relevant portions of Gandhi’s
disclosure. 15
Dr. Krӧcher also testifies that Gandhi’s written description does not provide
additional details as to how the three-way catalyst, the lean NOx trap and SCR
catalytic converter would be implemented. Ex. 2009, ¶ 67. That testimony seems
to assert that one skilled in the art would not be able to implement the
combination. However, Bandl-Konrad has not argued that any of Gandhi’s 20
claimed subject matter is not supported by an enabling disclosure. Thus, the lack
of additional implementing details does not detract from the specific teachings of
Gandhi’s disclosure referred to above.
We find that the portions of Gandhi’s disclosure cited above in combination
with the remainder of the disclosure are sufficient to convey an oxidation catalytic 25
converter as the first exhaust gas aftertreatment component, as recited in Gandhi
Claims 11, 19, and 46.
28

3) Using an NO2 Producing Catalytic Converter Upstream of the SCR
Catalytic Converter, Reacting NO to NO2 upstream of the NH3-SCR
Catalyst Converter and Increasing the Ratio of NO2 in the Exhaust Gas
5
Claims 13, 28, 32, 35, 48, and 49
Dependent Claim 13, which depends upon base Claim 11, further comprises
“an NO2 producing catalytic converter disposed upstream of the SCR catalytic
converter.” Ex. 2002, Claim 13.
Dependent Claim 28, which depends upon base Claim 19, further comprises 10
“enhancing an NO2 ratio of the nitrogen oxides in the exhaust gas … with an NO2
producing catalytic converter disposed upstream of the SCR catalytic converter.”
Ex. 2002, Claim 28.
Similar to Claim 28, dependent Claims 32, 35, and 48 require “oxidizing a
portion of NO in the exhaust gas to NO2 in a catalyst disposed upstream of the 15
NH3-SCR catalyst. Ex. 2002, Claims 32, 35, and 48. Alternatively, dependent
Claim 49 simply requires “reacting NO to NO2 upstream of the NH3-SCR
catalyst.” Ex. 2002, Claim 49.
Bandl-Konrad again relies on Dr. Krӧcher’s testimony that there is no
written description for these features. Paper 31, pp. 11-14. We have fully 20
considered Dr. Krӧcher’s testimony which appears at ¶¶ 73-82, 87-90, 92-95, and
97-98 of his declaration (Ex. 2009). However, we do not accord Dr. Krӧcher’s
testimony significant weight. Dr. Krӧcher has not provided an adequate reason as
to why one skilled in the art would disbelieve the plain teachings of Gandhi’s
disclosure. 25
Gandhi, in describing Figure 2 states: “As illustrated in FIG. 2, the lean NOx
adsorber emits NO, NO2, NH3, and N2O. These same gases then pass through the
NH3-SCR, where NH3 is stored.” Specification, p. 8, [0032]; FFs. 7-14. Gandhi’s
29

Figure 2, reproduced below, illustrates the production of NO2 in the lean NOx
absorber.

As shown in Gandhi’s Figure 2, exhaust gas containing NO enters the lean
NOx absorber. A combination of gases including NO2 leaves the lean NOx 5
absorber and enters the NH3-SCR catalytic converter. Thus, Gandhi expressly
describes an NO2 producing catalytic converter upstream of the SCR catalytic
converter and reacting NO to NO2 upstream of the NH3-SCR catalyst converter.
Gandhi’s disclosure is also consistent with Dr. Krӧcher’s testimony from his
deposition on January 10, 2012. There, Dr. Krӧcher admitted that a three-way 10
catalyst (“TWC”) and lean NOx absorber (LNT), as shown in Gandhi’s Figure 2,
can oxidize NO to form NO2:
Q. You agree that a TWC can oxidize NO to form NO2 under lean
conditions; right?
A. It can do. However, only to a limited extent 15
Q. And you agree that Gandhi discloses a TWC upstream of the
LNT, SCR system, don’t you?
A. Yeah.
MR. JACOBS: Objection.
A. Correct. 20
BY MR. HUNTINGTON
Q. And you would agree that under lean conditions the TWC
would oxidize NO to form NO2, wouldn’t it?
A. Yes, but again only to a very limited extent. It is not a
specialized NO2 producing catalytic converter. 25
Q. Claim 13 does not call for a specialized NO2 producing
catalytic converter, does it?
30

MR. JACOBS: Objection.
A. No, that’s correct.
BY MR. HUNTINGTON:
Q. And you would agree that a lean NOx trap oxidizes NO to form
NO2; right? 5
A. Correct.

Ex. 1028, p. 80, ll. 1-12.
Dr. Krӧcher has not presented a scientific basis why Gandhi’s straight
forward description is not valid or believable. Nor has Dr. Krӧcher provided a 10
scientific reason why the operation of the lean NOx absorber as described and
illustrated by Fig. 2 would not increase the “NO2 ratio of the nitrogen oxides in the
exhaust gas.” Because as illustrated in Figure 2, the NO2 is formed during the
passage of the exhaust gas through the lean NOx absorber, the NO2 ratio of
nitrogen oxides in the exhaust gas would necessarily increase. 15
For these reasons, Bandl-Konrad has not satisfied its burden of establishing
that Gandhi’s written description does not describe an NO2 producing catalytic
converter upstream of the SCR catalytic converter, reacting NO to NO2 upstream
of the NH3-SCR catalyst converter or increasing the ratio of NO2 ratio of nitrogen
oxides in the exhaust gas, as recited in Gandhi Claims 13, 28, 32, 35, 48, and 49. 20

4) Particulate Filter
Claims 11-13 and 20
Claim 11 and its dependent Claims 12-13 define an installation for
aftertreatment of exhaust gas generated by a diesel engine of a motor vehicle 25
comprising four required exhaust gas purification (aftertreatment) components
arranged in a specific order in relation to each other and the exhaust gas flow. Ex.
2002, Claims 11-13. As expressly defined in Gandhi Claims 11-13, the exhaust
gas flows through the four components in the following order:
31

1. an oxidation catalytic converter;
2. a nitrogen oxide (NOx) storage catalytic converter;
3. a particulate filter; and
4. an SCR catalytic converter.
Claim 20, similarly requires the same order of components. Ex. 2002, 5
Claim 20.
Bandl-Konrad argues, inter alia, that Gandhi’s original specification does
not provide a written description of a particulate filter “arranged upstream of the
SCR catalytic converter and downstream of the nitrogen oxide storage catalytic
converter.” Paper 31, pp. 6-8 10
We have reviewed the Gandhi’s written description and fail to see where
Gandhi describes this specific arrangement. As pointed out by Bandl-Konrad,
Gandhi’s written description only makes a single mention of particulate filters:
The invention also contemplates engineering such combinations
within the pores of the monolithic substrate. An example of this 15
is incorporating washcoat into porous substrates used for
filtering diesel particulate matter. Thus, this lean NOx trap/
NH3-SCR catalyst concept can be integrated into diesel
particulate matter devices.

Ex. 1005, ¶[0054]. However, this paragraph is silent on the location of the
particulate filter and does not describe a structure where the particulate filter is
located between the two catalytic converters.
Gandhi’s opposition does not direct us to a specific portion of the written
description that expressly describes a particulate filter at the required location. 25
Instead, Gandhi relies on the disclosure presented by Figs. 4 and 7 and the
testimony of Dr. Michael Harold (Ex. 1030). Paper 40, p. 6, l. 6 – p. 8, l. 4. Dr.
Harold testifies that the person having ordinary skill in the art would understand
the reference to “porous substrates used for filtering diesel particulate matter” in
32

¶52 of Gandhi’s written description refers to be “wall-flow” filters. Ex. 1030, p.
43, ¶158, ll. 11-13. Dr. Harold’s testimony includes a drawing said to show how
such a filter operates. Ex. 1030, p. 43, ¶158, ll. 13-16. The drawing is reproduced
below:
5
The drawing is admittedly not disclosed in Gandhi’s application. Ex. 1030,
p. 43, ¶158, ll. 13. Dr. Harold then combined the structure shown in the particulate
filter drawing with Gandhi’s Figs. 4 and 7 testifying that:
“the combination of the configurations shown in Figures 4 and 7 into
a porous substrate for filtering diesel particulate matter would result in 10
a system having a particulate filtering component located between a
lean NOx trap and SCR catalyst.”

Ex. 1030, p. 50, ¶173, ll. 14-17. Dr. Harold created the drawing, reproduced
below, said to be “an example” of the integration the structure of Gandhi Fig. 7b 15
into a diesel particulate matter device: Ex. 1030, p. 50, ¶173, ll. 17-19.
33

Ex. 1030, p. 51. The combination drawing also is not present in Gandhi’s
disclosure. Nevertheless, Dr. Harold testifies that:
“[i]n this arrangement, the exhaust gas would contact a Lean
NOx Trap formulation, the porous substrate, and a SCR Catalyst 5
formulation in that order.”

Ex. 1030, p. 50, ¶173, ll. 19-20.
Dr. Harold similarly combines the “known” particulate filter structure with
the arrangement shown in Gandhi’s Figures 4a-4c to arrive at another structure 10
having the sequence required by Claim 11:
when one applies the various configurations to the porous
substrate used for particulate filtration, such as in Figure
4a, the result is a system that has an integrated Lean NOx
Trap-Particulate Filter zone, and SCR Catalyst-15
Particulate Filter zone, such that one has a system where
a Particulate Filter is located downstream of the Lean
NOx Trap and also upstream of the SCR Catalyst.
Ex. 1030, 52:13-17.
Dr. Harold created the following drawing to illustrate the resultant sequence: 20
Ex. 1030, p. 52, ¶175.
34

The drawing also does not appear in Gandhi’s disclosure. Dr. Harold then
testifies that Gandhi has written descriptive support for a particulate filter located
downstream of the lean NOx trap and also upstream of the SCR Catalyst. Ex. 5
1030, p. 53, ¶176, ll. 6-7.
We do not credit Dr. Harold’s testimony on these points. First, Dr. Harold’s
testimony does not provide any basis for the statement that that one skilled in the
art would recognize that the “porous substrates used for filtering diesel particulate
matter” as used in Gandhi’s written description refers to “wall-flow” filters. We 10
are not required to credit the unsupported assertions of an expert witness. Rohm
and Haas Co. v. Brotech Corp., 127 F.3d 1089, 1092 (Fed. Cir. 1997). See also,
Standing Order, Paper 2, ¶158.1.1.
Second, to the extent “wall-flow” filters are conventional in the art, Gandhi
appears to presume that whatever was conventionally known by those in the art 15
was actually considered part of the invention by the inventors and considered to
have been described in the specification. No basis exists for that presumption.
Third, the proposed combination of the undisclosed structure of “wall-flow”
filters with the structures shown in Gandhi’s Figures. 4 and 7 to arrive at the
structures proposed by Dr. Harold’s appear to be a matter of “obviousness” rather 20
35

than “written description.” As we have noted above, the test for written
description is not obviousness. Rather, the specification must convey with
reasonable clarity to one with ordinary skill in the art that as of the filing date of
the application the inventor was in possession of the claimed invention. Vas-Cath
Inc., 935 F.2d at 1563-64; see also Pandrol USA, LP, 424 F.3d at 1165. The 5
pertinent question in analyzing written description is: did the written description
objectively tell to the person skilled in the art that the inventor contemplated the
subject matter now claimed.
For the foregoing reasons, Bandl-Konrad has met its burden to establish by a
preponderance of the evidence that Gandhi Claims 11-13 and 20 are unpatentable 10
under 35 U.S.C. § 112, first paragraph, for lacking written description support for a
“particulate filter” that is arranged at the specific location required by the claims,
i.e., “upstream of the SCR catalytic converter and downstream of the nitrogen
oxide storage catalytic converter.” Accordingly, we hold that Bandl-Konrad has
shown that Gandhi Claims 11-13 and 20 are unpatentable under 35 U.S.C. § 112, 15
first paragraph, as lacking written description support.

Claims 10, 31, 34 and 47
Dependent Claims 10, 31, 34 and 47 also require a particulate filter. Each of
these claims adds the specific limitation requiring “filtering particulate matter in 20
the exhaust gas.” Ex. 2002, Claims 10, 31, 34, and 47.
Bandl-Konrad makes essentially the same arguments against Gandhi Claims
10, 31, 34 and 47 that were made with respect to Claims 11-13 and 20, i.e., that
written description support is lacking because “it would not be possible to arrange
the particulate filter upstream of the NH3-SCR washcoat and downstream of the 25
lean NOx trap (LNT) washcoat.” Paper 31, p. 14, Ex. 2009, ¶103.
36

Bandl-Konrad’s argument is not persuasive. We note that Gandhi Claims
10, 31, 34, and 47 do not require a specific arrangement or location for the
particulate filter. Instead, those claims merely require “filtering particulate matter
in the exhaust gas.” Gandhi written description expressly teaches using a
particulate filter. Gandhi Specification, p. 15, [0015]; FFs. 7-14. That disclosure 5
alone is sufficient to provide written descriptive support for the broadly worded
“filtering particulate matter,” as recited in Gandhi Claims 10, 31, 34, and 47.
Bandl-Konrad has failed to prove that Gandhi Claims 10, 31, 34 and 47 are
unpatentable under 35 U.S.C. § 112, first paragraph, for lacking a written
description support. 10

4.
In summary, Bandl-Konrad has met its burden to prove that Gandhi Claims
11-13 and 20 are unpatentable under 35 U.S.C. § 112, first paragraph, for lacking a
written description support. However, Bandl-Konrad has failed to prove that 15
Gandhi Claims 10, 19, 28, 31, 32, 34, 35, and 46-49 are unpatentable under 35
U.S.C. § 112, first paragraph, for lacking a written description support. Therefore,
Bandl-Konrad Motion 3 (Paper 31) is GRANTED as to Gandhi Claim 11-13 and
20, and is otherwise DENIED as to Gandhi Claims 10, 19, 28, 31, 32, 34, 35, and
46-49. 20

IV. BANDL-KONRAD MOTION 4 (PAPER 32) SEEKING ENTRY OF
JUDGMENT AGAINST GANDHI BASED ON AN ALLEGED LACK OF
PATENTABILITY UNDER 35 U.S.C. §§ 102 & 103
25
In Bandl-Konrad Motion 4 (Paper 32), Bandl-Konrad moves for judgment
that Claims 9, 10, 19, 30-35, and 46-49 of Gandhi’s involved application, U.S.
Application Serial No. 12/706,558 (“Gandhi ‘558 application”) (pending Claims
37

attached as Ex. 2002) are unpatentable over the prior art under one or both of 35
U.S.C. §§ 102 and 103. To prevail on this motion, Bandl-Konrad bears the burden
of proving by a preponderance of evidence that Claims 9, 10, 19, 30-35, and 46-49
of Gandhi ‘558 application are unpatentable over prior art. 37 C.F.R. § 41.121(b).
Specifically, Bandl-Konrad argues: (1) Claims 9 and 46 of Gandhi’s 5
involved application are unpatentable under 35 U.S.C. §§ 102 and 103 as being
anticipated or rendered obvious over Kinugasa, U.S. Patent No. 6,109,024
(Kinugasa ‘024; Ex. 2004); (2) Claims 19, 30, 32, 33 and 35 of Gandhi’s involved
application are unpatentable under 35 U.S.C. § 102(b) as being anticipated by
Kinugasa ‘024 (Ex. 2004); (3) Claims 10, 31, 34 and 47 of Gandhi’s involved 10
application are unpatentable under 35 U.S.C. § 103(a) as rendered obvious over
Kinugasa ‘024 (Ex. 2004) and Twigg, PCT International Application No. 00/21647
(Twigg ‘647; Ex. 2013); and (4) Claims 48-49 of Gandhi’s involved application
are unpatentable under 35 U.S.C. § 103(a) as rendered obvious over Kinugasa ‘024
(Ex. 2004). In addition, Bandl-Konrad also argues, pursuant to the presumption 15
under 37 C.F.R. §41.207(c), that the asserted prior art does not anticipate or render
obvious any claims of Bandl-Konrad ‘747 patent.
In its opposition (Paper 41), Gandhi does not contest Bandl-Konrad’s
general contention regarding the unpatentability of Gandhi’s claims; rather, Gandhi
opposes to the extent that should Gandhi Claims 9, 10, 19, 30-35, and 46-49 be 20
held unpatentable, Bandl-Konrad Claims 1-19 should also be held unpatentable for
the same reasons. Gandhi Opposition 4 (Paper 41), p. 1.
However, in light of our decision re: Bandl-Konrad Motion 3 (Paper 31)
holding that Gandhi Claims 11-13 and 20 have been shown as unpatentable under
35 U.S.C. §112, first paragraph, for lack of written description support from 25
Gandhi ‘558 application, and Gandhi remaining Claims 9, 10, 19, 28, 30-35, and
46-49 (including unchallenged Claims 9, 30, and 33) have not been shown as
38

unpatentable under 35 USC §112, first paragraph, we exercise our discretion under
37 C.F.R. §1.125(a) to review Bandl-Konrad’s challenges only with respect to
Gandhi remaining Claims 9, 10, 19, 28, 30-35, and 46-49. With respect to these
remaining claims, Bandl-Konrad’s arguments against patentability under one or
both of 35 U.S.C. §§ 102(b) and 103(a) can be summarized as follows: 5
(1) Claims 9, 19, 30, 32, 33, 35, 46, and 49 are anticipated under 35
U.S.C. § 102(b) by Kinugasa, U.S. Patent No. 6,109,024 (Kinugasa ‘024;
Ex. 2004); and

(2) Claims 10, 31, 34, and 47 would have been obvious under 35 10
U.S.C. § 103(a) over Kinugasa ‘024 and Twigg, PCT International
Application Publication No. WO 00/21647 (Twigg ‘647; Ex. 2013).

A. Additional Findings of Fact
Kinugasa ‘024 Patent

28. Kinugasa ‘024 issued on August 29, 2000, and as such, qualifies as prior
art under 35 U.S.C. §102(b) against both Bandl-Konrad ‘747 patent and 20
Gandhi’s 558 application and its grandparent, Gandhi ‘470 application.
Ex. 2004, Kinugasa ‘024.
29. Kinugasa ‘024 discloses an exhaust gas purification system for an
internal combustion engine, shown in Fig. 1, capable of removing NOx in
the exhaust gas of a lean burn engine with high efficiency. Kinugasa 25
‘024, col. 1, ll. 9-11; col. 6, ll. 43-46 (diesel fuel); col. 9, ll. 17-19. Fig. 1
is reproduced below.
39

As shown in Fig. 1, the exhaust gas purification system includes in the
direction of the exhaust gas flow from engine 1, a three-way catalyst 5, a
NOx absorbing-reducing catalyst 7, and a NH3 adsorbing-denitrating
catalyst 9. The three-way catalyst 5 is arranged upstream of NOx 5
absorbing-reducing catalyst 7 and NH3 adsorbing-denitrating catalyst 9,
as a first exhaust gas treatment component as seen by the direction of
flow of exhaust gas. The NH3 adsorbing-denitrating catalyst 9 is
arranged downstream of the NOx absorbing-reducing catalyst 7. Ex.
2004, Fig. 1; Ex. 2014, §51. 10
30. The term “three-way catalyst” as used in Kinugasa ‘024 (Ex. 2004) and
the term “oxidizing catalytic converter” or “catalytic capable of
oxidizing” as used in Claims 9, 30, and 33 of the Bandl-Konrad ‘747
patent (Ex. 1003) are interchangeable and refer to the same technology.
Declaration of Oliver Krӧcher, Ph.D., in support of Bandl-Konrad 15
Motion 4 (Paper 32), Ex. 2014, ¶¶51-52.
31. The term “NOx absorbing-reducing catalyst” as used in Kinugasa ‘024
(Ex. 2004) and the term “nitrogen oxide absorber” as used in Claims 9,
30, and 33 of the Bandl-Konrad ‘747 patent (Ex. 1003) are
interchangeable and refer to the same technology. Id., ¶¶56-58. 20
40

32. The term “NH3 absorbing-denitrating catalyst” as used in Kinugasa ‘024
(Ex. 2004) and the term “NH3-SCR catalyst” as used in Claims 9, 30, and
33 of the Bandl-Konrad ‘747 patent (Ex. 1003) are interchangeable and
refer to the same type of component. Id., ¶¶64-66.
33. Kinugasa ‘024 discloses in the Background of the Invention section that 5
it was known to operate engine cylinders with rich air-fuel ratios. Ex.
2004, Kinugasa ‘024, Background of the Invention.
34. Kinugasa ‘024 further discloses that the fuel injection valves are
controlled so that the engine cylinders include alternating lean and rich
air-fuel ratios. Ex. 2004, Kinugasa ‘024, Abstract. 10
35. Kinugasa ‘024 discloses that controlling the direct cylinder injection to
the engine to generate lean and rich air-fuel ratios teaches both the
specific recitation of controlling engine operations, and the broader
recitation of lean and rich conditions during lean and rich cycles of
Gandhi Claims 9, 30, and 33. Ex. 2004, Kinugasa ‘024, col. 6, ll. 18-26. 15
36. Kinugasa ‘024 discloses that the amount of NOx produced by the engine
varies depending upon air intake amount and engine speed. Ex. 2004,
Kinugasa ‘024, col. 14, ll. 23-30.
37. Kinugasa ‘024 discloses that the three-way catalyst 5 receives exhaust
gas from engine 1 and converts carbon hydrocarbons (HC) and carbon 20
monoxide (CO) contained in the exhaust gas under lean conditions or
when the air-fuel ratio becomes lean (λ>1.0). Ex. 2004, Kinugasa ‘024,
col. 7, ll. 6-11.
38. Kinugasa ‘024 further discloses that the catalytic material of three-way
catalyst 5 is platinum Pt, rhodium Rh or palladium Pd. Ex. 2004, 25
Kinugasa ‘024, col. 7, ll. 4-5 and 39-41.
41

39. In 1994, it was known that with excess oxygen, the three-way catalyst
acts as an oxidation catalyst, removing all reducing species (CO, HC).
Ex. 2015, M. Shelef, G.W. Graham, Why Rhodium in Automotive Three-
Way Catalysts?, Chem. Rev. Sci. Eng. 36(3), 433-457, at 437-48 (1994).
Ex. 2014, ¶18. 5
40. Kinugasa ‘024 discloses that NOx absorbing-reducing catalyst 7 (shown
in Fig. 1) receives exhaust gas from three-way catalyst 5 and absorbs
NOx in the exhaust gas in the form of nitric acid ions when the air-fuel
ratio of the exhaust gas is lean (i.e., when the excess air ratio λ is larger
than 1.0) and releases the absorbed NOx when the excess air-fuel ratio λ 10
of the exhaust gas flowing the NOx absorbing-reducing catalyst becomes
smaller than 1.0 (i.e., the air-fuel ratio becomes rich). Ex. 2004,
Kinugasa ‘024, col. 8, ll. 13-20.
41. Accordingly, the disclosure of Kinugasa ‘024 of NOx absorbing-reducing
catalyst 7 (shown in Fig. 1) absorbing NOx discloses the storing, 15
temporarily storing, and absorbing functions of the nitrogen oxide
absorber and the lean nitrogen oxide absorber as recited in Gandhi
Claims 9, 30, and 33.
42. Kinugasa ‘024 also discloses that NOx absorbing-reducing catalyst 7
(shown in Fig. 1) also converts NOx in the exhaust gas to NH3 by a 20
mechanism exactly the same as that of the three-way catalyst. Kinugasa
‘024, col. 8, ll. 61-63.
43. Accordingly, the disclosure of Kinugasa ‘024 of NOx absorbing-reducing
catalyst 7 (shown in Fig. 1) converting NOx to NH3 and providing the
NH3 downstream discloses the reducing, and purging steps of Gandhi 25
Claims 9, 30, and 33.
42

44. Kinugasa ‘024 discloses that NH3 adsorbing-denitrating catalyst 9 is
arranged downstream of the NOx absorbing-reducing catalyst 7 (shown in
Fig. 1) to adsorb the generated ammonia (NH3) and use the adsorbed NH3
to reduce NOx in the exhaust gas. Ex. 2004, Kinugasa ‘024, col. 9, ll. 13-
16 and 42-44. 5
45. Accordingly, the disclosure of Kinugasa ‘024 of NH3 adsorbing-
denitrating catalyst 9 (shown in Fig. 1) adsorbing NH3 discloses the
absorbing and storing NH3 or absorbing in a NH3–SCR catalyst of
Gandhi Claims 9, 30, and 33.
46. Accordingly, the disclosure of Kinugasa ‘024 of NH3 adsorbing-10
denitrating catalyst 9 (shown in Fig. 1) reducing NOx using NH3 discloses
the reacting step of Gandhi Claims 9, 30, and 33.

Twigg ‘647 Application
47. Twigg, PCT International Application Publication No. WO 00/21647 15
(“Twigg ‘647”) discloses a system and method for the control of
emissions of a diesel engine exhaust containing CO, HC, NO, O2, soot
and non-reactive gases, shown in the sole drawing as reproduced below.
43

As shown in the sole figure of Twigg ‘647, the system comprises a
catalyst 14 to convert NO to NO2, a particulate filter 16 to collect
particles, and a NOx absorber 28 with means to regenerate the NOx
absorber by injecting reductant or other reactant upstream of the NOx 5
absorber, and at least during regeneration, passing the exhaust gases, via
a three-way catalyst 30. Ex. 2013, Twigg ‘647; Abstract, p. 3, ll. 6-15, p.
7, ll. 29-30.
48. According to Twigg ‘647, filtering particulate matter is a well-known
technique used in exhaust gas purification systems, particularly when 10
these systems are used with engines consuming diesel fuel, such as those
disclosed by Kinugasa ‘024. Ex. 2013; Twigg ‘647; Abstract; p. 3, ll. 6-
15; p. 7, ll. 29-30, element 16 in the sole figure; Ex. 2004, Kinugasa
‘024, col. 6, ll. 43-46; also see Bandl-Konrad ‘747 patent, Background
Section, col. 3, ll. 28-43. 15

Analysis
1.
Claim Construction
In determining patentability over the prior art, the name of the game is the
claim. In re Hiniker Co., 150 F.3d 1362, 1369 (Fed. Cir. 1998). Claim terms of an 5
involved patent in an interference are given their broadest reasonable construction
as they would be understood by one of skill in the art in light of the specification .
Rolls-Royce PLC v. United Technologies Corp., 603 F.3d 1325 (Fed. Cir. 2010).
For purposes of a patentability or invalidity challenge under 35 U.S.C. §§ 102 and
103, the copied claims must be interpreted in light of the host disclosure, i.e., 10
Gandhi’s disclosure and file history. Agilent Tech., 567 F.3d at 1375 (“[W]hen a
party challenges a claim’s validity under §§ 102 and 103 … the Board must
interpret the claim in light of the specification in which it appears”). Paper No. 42,
p. 5, ll. 11-14.
We will look to Gandhi’s disclosure and file history to see if they provide a 15
definition for claim terms. Otherwise, we give them their “ordinary and customary
meaning” in the light of the specification that “the term would have to a person of
ordinary skill in the art in question at the time of the invention, i.e., as of the
effective filing date of the patent application.” Phillips v. AWH Corp., 415 F.3d at
1313. Neither Beckmann nor Gandhi has alleged that the inventors gave any claim 20
term a special definition different from its recognized meaning to one with
ordinary skill.
In this case, analysis of the unpatentability assertions depends on the
meaning of the claim terms “nitrogen oxide absorber”, “NH3-SCR catalyst,”
“oxidizing catalytic converter” or “catalyst capable of oxidizing” as recited in 25
Gandhi Claims 9, 30, and 33 in the context of Gandhi ‘558 application. However,
as testified by Dr. Krӧcher, the term “oxidizing catalytic converter” or “catalytic
45

capable of oxidizing” as used in Claims 9, 30, and 33 of the Bandl-Konrad ‘747
patent is interchangeable with the “three-way catalyst” as used in Kinugasa ‘024
and encompasses the same. Ex. 2014, ¶¶51-52; FFs. 5-6, and 30. Similarly, the
term “nitrogen oxide absorber” as used in Claims 9, 30, and 33 of the Bandl-
Konrad ‘747 patent is interchangeable with the “NOx absorbing-reducing catalyst” 5
as used in Kinugasa ‘024 and refers to the same type of component. Id., ¶¶56-58;
FF 31. Likewise, the term “NH3-SCR catalyst” as used in Claims 9, 30, and 33 of
the Bandl-Konrad ‘747 patent is interchangeable with the term “NH3 absorbing-
denitrating catalyst” as used in Kinugasa ‘024 (Ex. 2004) and refers to the same
type of component. Id., ¶¶64-66; FF 32. For purposes of this decision we proceed 10
on the basis of Dr. Krӧcher’s testimony, which has not been sufficiently rebutted
by Gandhi.

2.
Legal Standard for 35 U.S.C. §102(b) and §103(a) 15
In order to find anticipation under 35 U.S.C. §102(b), a single prior art
reference must disclose each and every element of a claim, either expressly or
inherently. In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997); Finnigan Corp.
v. Int’l Trade Comm’n, 180 F.3d 1354, 1365 (Fed. Cir. 1999). As the moving
party, Bandl-Konrad bears the burden of proof to establish entitlement to the relief 20
requested. 37 C.F.R. § 41.121(b).
A patent claim is also unpatentable under 35 U.S.C. § 103(a) if the
differences between the claimed subject matter and the prior art are such that the
subject matter as a whole would have been obvious at the time the invention was
made to a person having ordinary skill in the art to which said subject matter 25
pertains. KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of
obviousness is resolved on the basis of underlying factual determinations
46

including: (1) the scope and content of the prior art, (2) any differences between
the claimed subject matter and the prior art, (3) the level of skill in the art, and (4)
where in evidence, so-called secondary considerations. Graham v. John Deere Co.
of Kansas City, 383 U.S. 1, 17-18 (1966).
Beckmann’s expert, Dr. Krӧcher has determined, and Gandhi has not 5
rebutted, the appropriate level that someone of ordinary skill in the art of exhaust
gas purification systems for internal combustion engines would have, that is, a
bachelor’s degree in chemistry, mechanical engineering, automotive engineering,
or chemical engineering and seven years’ work experience in the field, or a
master’s degree in chemistry, mechanical engineering, automotive engineering, or 10
chemical engineering and five years’ work experience in the field. Ex. 2014, ¶11.
Rather, Gandhi’s expert, Dr. Harold considers that a person skilled in the art to
have at least 2 years of laboratory experience conducting catalyst research. Ex.
1001, ¶9; Ex. 1030, ¶46.

Gandhi Claims 9, 19, 30, 32, 33, 35, 46, 48 and 49 as Anticipated
by Kinugasa ‘024

Gandhi Claim 9 defines a method for the reduction of nitrogen oxides and 20
ammonia from diesel engine exhaust gas, said method comprising:
storing nitrogen oxides present in the exhaust gas in a nitrogen
oxide absorber during lean cycles with a lean exhaust gas air ratio;
reducing stored nitrogen oxides from the nitrogen oxide
absorber during rich pulses, which contain a rich exhaust gas air ratio, 25
and thereby generating ammonia;
adsorbing and storing ammonia in a NH3-SCR catalyst arranged
downstream of the nitrogen oxide absorber;
reacting the stored ammonia with nitrogen oxides in the NH3-
SCR catalyst; 30
operating the engine under lean conditions during lean cycles;
47

during lean cycles, oxidizing carbon monoxide and
hydrocarbons contained in the exhaust gas in an oxidizing catalytic
converter arranged upstream of the nitrogen oxide absorber and NH3-
SCR catalyst;
operating the engine under rich conditions during rich cycles. 5

Ex. 2002; Gandhi ‘558 application, Claim 9 (emphasis added).
Gandhi Claim 33 is similar to Claim 9 in scope of coverage, except that a
generic “catalyst capable of oxidizing” is recited instead of “an oxidizing catalytic
converter” as recited in Gandhi Claim 9. In contrast, Gandhi Claim 30 is broader 10
in scope than Gandhi Claim 9 and does not contain limitations regarding the
operation of the engine under lean conditions during lean cycles and under rich
conditions during rich cycles.
Likewise, Gandhi Claims 19 and 46 are also similar to Claim 9 in scope,
except that an oxidizing catalytic converter or a catalyst arranged as “a first 15
exhaust gas aftertreatment component, as seen in the direction of flow of the
exhaust gas” is recited.
As expressly defined in Gandhi Claims 9, 19, 30, 33 and 46, there are
several operative steps, including:
 Using an oxidizing catalytic converter or a catalyst arranged as a 20
first exhaust gas aftertreatment component upstream from a
nitrogen oxide catalytic converter and a NH3-SCR converter, to
oxidize carbon monoxide (CO) and hydrocarbons (HC);

 Using the nitrogen oxide catalytic converter to adsorb/store/reduce 25
nitrogen oxides (NOx) and generate ammonia (NH3);

 Using an SCR catalytic converter arranged downstream from the
nitrogen oxide catalytic converter, to adsorb/store/reduce ammonia
(NH3) released by the nitrogen oxide catalytic converter; and 30

 Operating the engine under lean and rich conditions.

Ex. 2002; Gandhi ‘558 application, Claims 9, 30, and 33.
Gandhi Claims 32, 35, and 48 depend upon Claims 30, 33, and 46
respectively, and further comprise:
“oxidizing a portion of NO in the exhaust gas to NO2 in a catalyst
disposed upstream of the NH3-SCR catalyst.” 5

Ex. 2002; Gandhi ‘558 application, Claims 32, 35, and 48.
Gandhi Claim 49 depends upon Claim 9, and further comprises:
“reacting NO to NO2 upstream of the NH3-SCR catalyst.”
Ex. 2002, Gandhi ‘558 application, Claim 49. 10
In Bandl-Konrad Motion 4 (Paper 32), Bandl-Konrad contends that each and
every element of Gandhi Claims 9, 19, 30, 32, 33, 35, 46, 48 and 49 is described or
disclosed, either explicitly or inherently, by Kinugasa ’024. Kinugasa ‘024 is said
to “anticipate” the invention of Gandhi Claims 9, 19, 30, 32, 33, 35, 46, 48 and 49.
Specifically, Bandl-Konrad contends that Kinugasa ‘024 discloses an 15
exhaust gas purification system for an internal combustion engine capable of
removing NOx in the exhaust gas of a lean burn engine with high efficiency.
Kinugasa ‘024, col. 1, ll. 9-11; col. 6, ll. 43-46 (diesel fuel); col. 9, ll. 17-19.
Fig. 1 of Kinugasa ‘024 is reproduced below.
20
49

As shown in Fig. 1, the exhaust gas purification system includes in the
direction of the exhaust gas flow from engine 1, a three-way catalyst 5, a NOx
absorbing-reducing catalyst 9, and a NH3 adsorbing-denitrating catalyst 9. The
three-way catalyst 5 is arranged upstream of NOx absorbing-reducing catalyst 9
and NH3 adsorbing-denitrating catalyst 9 as a first exhaust gas treatment 5
component as seen by the direction of flow of exhaust gas. The NH3 adsorbing-
denitrating catalyst 9 is arranged downstream of the NOx absorbing-reducing
catalyst 9. Ex. 2004, Fig. 1; Ex. 2014, §51; FF 29.
Bandl-Konrad proffers detailed explanations and analyses regarding how
each element of Claims 9, 19, 30, 32, 33, 35, 46, 48, and 49 of Gandhi ‘558 10
application is met by Kinugasa ‘024, as set forth in the claim charts attached as
APPENDIX 3 – Attachments A, E, F, H, I, O, J, K, P and Q. Paper 32, pp. 5-13 &
APPENDIX 3 (claim charts); FFs. 28-46.
We find Bandl-Konrad’s explanations regarding Gandhi Claims 9, 19, 30,
32, 33, 35, 46, 48, and 49 persuasive and supported by the record. Gandhi has not 15
proffered a rebuttal to Bandl-Konrad’s assertions regarding Kinugasa ‘241. In the
absence of Gandhi’s opposition, we conclude that Bandl-Konrad has demonstrated
by a preponderance of the evidence that Claims 9, 19, 30, 32, 33, 35, 38, 46, 48,
and 49 of Gandhi’s involved application are unpatentable under 35 U.S.C. § 102(b)
as being anticipated by Kinugasa ‘024. 20

Gandhi Claims 10, 31, 34 and 47 as Rendered Obvious
by Kinugasa ‘024 and Twigg ‘647

Gandhi Claims 10, 31, 34 and 47 depend upon independent Claims 9, 30, 33 25
and 46, respectively, and further comprise “filtering particulate matter in the
exhaust gas.” Ex. 2002, Gandhi ‘558 application, Claims 10, 31, 34, and 47
(emphasis added).
50

In Bandl-Konrad Motion 4 (Paper 32), Bandl-Konrad contends, as
confirmed by Dr. Krӧcher’s testimony (Ex. 2009), that filtering particulate matter
is a well-known technique used in exhaust gas purification systems, particularly
when these systems are used with engines consuming diesel fuel, such as those
disclosed by Kinugasa ‘024, col. 6, ll. 43-46; Ex. 2013, Twigg ‘647; Abstract, p. 3, 5
ll. 6-15, p. 7, ll. 29-30, element 16 in the sole figure; Ex. 2004; Bandl-Konrad ‘747
patent, Background Section, col. 3, ll. 28-43; FFs. 7-14, and 28-48.
Bandl-Konrad also proffers detailed explanations and analyses regarding the
differences between Claims 10, 31 and 34 of Gandhi ‘558 application and the
combination of Kinugasa ‘024 and Twigg ‘647, as set forth in the claim charts 10
attached as APPENDIX 3 – Attachments D, G, I and L.
We find Bandl-Konrad’s explanations regarding Gandhi Claims 10, 31, 34
and 47 persuasive and supported by the record. Again, Gandhi has not proffered a
rebuttal to Bandl-Konrad’s assertions regarding Kinugasa ‘241. In the absence of
Gandhi’s opposition, we conclude that modifying Kinugasa ‘024 with the well-15
known “filtering” technique of Twigg ‘647 to filter particulate matter in the
exhaust gas (without more) would involve nothing more than an obvious
combination of prior art elements according to known methods to yield predictable
results.
Thus, based on this record, we hold that Bandl-Konrad has shown by a 20
preponderance of the evidence that Claims 10, 31, 34, and 47 of Gandhi ‘558
application are unpatentable under 35 U.S.C. § 103(a) as rendered obvious over
Kinugasa ‘024 and Twigg ‘647.
Lastly, we note that Bandl-Konrad has not presented arguments against
patentability of Gandhi Claim 28. However, Gandhi Claim 28 depends upon 25
independent Claim 19, and contains similar features of Gandhi Claims 32, 35, 48,
and 49. For example, Gandhi Claims 32, 35, and 48 further recite “oxidizing a
51

portion of NO in the exhaust gas to NO2 in a catalyst disposed upstream of the
NH3-SCR catalyst.” Gandhi Claim 49 further recites “reacting NO to NO2
upstream of the NH3-SCR catalyst.” Ex. 2002, Gandhi ‘558 application, Claims
32, 35, 48, and 49 (emphasis added).
As previously noted, both Gandhi independent Claim 19 and dependent 5
Claims 35, 48, and 49 are found anticipated by Kinugasa ‘024 as Kinugasa ‘024
discloses a three-way catalyst 5 disposed upstream of NOx absorbing-reducing
catalyst 7 and NH3 absorbing-denitrating calalyst 9, to oxidize (or react) a portion
of NO in the exhaust gas to NO2 under lean conditions. Kinugasa ‘024, col. 8, ll.
13-20; FFs. 40-46. As shown in Fig. 1 of Kinugasa ‘024, the NO2 is formed during 10
the passage of the exhaust gas through the NOx absorbing-reducing catalyst 7, and
the NO2 ratio of nitrogen oxides in the exhaust gas would necessarily increase.
Similarly to Gandhi independent Claim 19 and dependent Claims 35, 48, and
49, Gandhi Claim 28 alternatively recites “enhancing an NO2 ratio of the nitrogen
oxides in the exhaust gas by means of a catalytic oxidation with an NO2 producing 15
catalytic converter disposed upstream of the SCR catalytic converter.” Ex. 2002,
Gandhi ‘558 application, Claim 28 (emphasis added). We see no practical
difference between the subject matter of Gandhi Claims 35, 48, and 49 and Gandhi
Claim 28 with respect to patentability. As such, Gandhi Claim 28 appears to have
been inadvertently omitted from Bandl-Konrad Motion 4 (Paper 32). For purposes 20
of completeness, we construe Gandhi Claim 28 as being included in Bandl-
Konrad’s arguments against patentability of Gandhi Claims 19, 32, 35, 48, and 49.
Consequently, we find that one skilled in the art would have recognized that
the NO2 ratio of the nitrogen oxides in the exhaust gas could have been enhanced
by way of disposing an NO2 producing catalytic converter, and conclude that it 25
would have been obvious to make such an enhancement by means of a catalytic
52

oxidation with an NO2 producing catalytic converter disposed upstream of the SCR
catalytic converter.”
In summary, for the reasons discussed above, we hold that Bandl-Konrad
has shown that Gandhi Claims 9, 10, 19, 28, 30-35, and 46-49 of Gandhi ‘558
application are unpatentable under 35 U.S.C. §§ 102(b) and 103(a) as being 5
anticipated or rendered obvious over Kinugasa ‘024 and Twigg ‘647.

4.
Presumption Under 37 C.F.R. §41.207(c)
A party moving for judgment based on prior art must also explain why the 10
prior art does not apply to the party’s claims. See Navarrini v. Worm, 79 USPQ2d
1178, 1183 (BPAI 2005). Specifically, 37 C.F.R. §41.207(c) states:
“When a motion for judgment of unpatentability against an
opponent’s claim on the basis of prior art is granted, each of the
movant’s claims corresponding to the same count as the opponent’s 15
claim will be presumed to be unpatentable in view of the same prior
art unless the movant in its motion rebuts this presumption.”

Initially, Bandl-Konrad provided no explanation why Bandl-Konrad’s
involved claims are not unpatentable over the prior art cited in Bandl-Konrad 20
Motion 4 (Paper 32). See 37 C.F.R. §41.207(c). Subsequently, Bandl-Konrad
counsel explained that the omission was an inadvertent error and requested
correction of such an error in its replies to Gandhi’s opposition, which was granted
in the April 30, 2012 Order (Paper 45).
15

15
Typically, a reply that raises a new issue will not be considered. SO ¶122.5.
However, Bandl-Konrad’s belated request to address the presumption was not
opposed by Gandhi and Gandhi was authorized to file a Sur-Reply in response
thereto, which was granted in the April 30, 2012 Order (Paper 45).
53

In Bandl-Konrad Reply 4 (Paper 49), Bandl-Konrad explains why Claims 1-
8, 10, 15-17, and 19 of Bandl-Konrad ‘747 patent are not unpatentable over the
same prior art. However, we note that Bandl-Konrad has failed to rebut the
presumption regarding Claims 9, 11-14, and 18 of Bandl-Konrad ‘747 patent. In
particular, Bandl-Konrad has not explained why Claims 9, 11-14, and 18 of Bandl-5
Konrad ‘747 patent are not unpatentable over the same prior art, and has even
admitted that Claim 9 is unpatentable over the same prior art cited in Bandl-
Konrad Motion 4 (Paper 32) including Kinugasa ‘024 and Twigg ‘647. Paper 49,
p. 2. Therefore, in view of Bandl-Konrad’s own admission, we hold that Bandl-
Konrad has failed to rebut the presumption under 37 C.F.R. §41.207(c) and that 10
Claims 9, 11-14, and 18 of Bandl-Konrad ‘747 patent are unpatentable over the
same prior art cited therein.
Rather, Bandl-Konrad presents arguments for patentability of Bandl-Konrad
Claims 1-8, 10, 15-17, and 19 by way of Dr. Oliver Krӧcher’s testimony, Ex. 2025,
Supplemental Declaration of Oliver Krӧcher, Ph.D., in support of Bandl-Konrad 15
Motion 4, ¶4, that none of the cited prior art, including Kinugasa ‘024 and Twigg
‘647 – either alone or in combination – discloses or suggests:
(1) a “particulate filter” arranged in a specific order, i.e., “upstream
of the SCR catalytic converter and downstream of the nitrogen oxide storage
catalytic converter,” as recited in Bandl-Konrad Claims 1-8 and 19; 20

(2) “filtering out particulates in the exhaust gas with a particulate
filter arranged downstream of the nitrogen oxide storage catalytic converter
and guiding filtered exhaust gas to the SCR catalytic converter” as recited in
Bandl-Konrad Claims 10, 16, and 17; and 25

(3) “hydrogen sulfide formed during the desulfation phases is
oxidized by the SCR catalytic converter” as recited in Bandl-Konrad Claim
15.
30
Paper 49, p. 3; Bandl-Konrad ‘747 patent, Claims 1-8, 10, 15-17, and 19.
54

We find Bandl-Konrad’s explanations regarding Bandl-Konrad Claims 1-8,
10, 15-17, and 19 persuasive and supported by the record. Bandl-Konrad has
established that the presumption does not apply to Claim 1-8, 10, 15-17 and 20 of
Bandl-Konrad ‘747 patent.
In response thereto, Gandhi contends, in its Sur-Reply (Paper 51), that 5
Claims 1-8, 10, 16, 17, and 19 of Bandl-Konrad ‘747 patent are unpatentable over
the same prior art, including Kinugasa ‘024 and Twigg ‘647 for two reasons: First,
Gandhi asserts that Bandl-Konrad has admitted that it would be obvious to add a
particulate filter as taught by Twigg ‘647 to the system disclosed by Kinugasa ‘024
(Ex 2014, ¶¶80-81). Paper 51, p. 3. Second, Gandhi argues that, given Dr. 10
Krӧcher’s contention that there are only a small, finite number of possible
locations where a person of skill in the art could add a separate and distinct
particulate filer to the system disclosed by Kinugasa ‘024 (Ex. 1037, ¶7; Ex. 1035,
page, 30, ll. 5-14), it would have been obvious to add a separate and distinct
particulate filter to any one of the small number of possible locations in the system 15
disclosed by Kinugasa ‘024. DyStar Textilfarben GmbH & Co. Deutschland KG
v., 464 F.3d at 1366, 80 USPQ2d at 1649 (motivation may be found in the
knowledge of one skilled in the art). Paper 51, pp. 3-4.
However, we are not so persuaded by Gandhi’s countervailing arguments.
First, Gandhi’s assertion regarding Bandl-Konrad’s admission is misplaced. The 20
cited ¶¶80-81 of Exhibit 2014, Dr. Krӧcher’s Declaration in support of Bandl-
Konrad Motion 4 (Paper 32) simply refers to the well-known “filtering” technique
used in exhaust gas purification systems as discussed in connection with Gandhi
Claims 10, 31, 34, and 47 and that modifying Kinugasa ‘024 with the well-known
“filtering” technique as disclosed, for example, by Twigg ‘647 to filter the 25
particulate filter (without more) would involve nothing more than an obvious
55

combination of prior art elements according to known methods to yield predictable
results. KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007).
In contrast to Gandhi Claims 10, 31, 34, and 47, Claims 1-8, 10, 16, 17 and
19 of Bandl-Konrad ‘747 patent require, among other features, a specific
arrangement of a particulate filter, i.e., “arranged upstream of the SCR catalytic 5
converter and downstream of the nitrogen oxide storage catalytic converter.” Ex.
2001; Bandl-Konrad ‘747 patent, Claims 1 and 10. Nowhere in Dr. Krӧcher’s
testimony (Ex. 2014) is there any admission regarding the specific arrangement of
Bandl-Konrad’s claimed “particulate filter arranged upstream of the SCR catalytic
converter and downstream of the nitrogen oxide storage catalytic converter,” as 10
recited in Bandl-Konrad Claims 1 and 10.
Second, neither Kinugasa ‘024 nor Twigg ‘647, whether taken in
combination or individually, discloses or suggests the specific arrangement of gas
exhaust aftertreatment components of Bandl-Konrad’s claimed “installation”
including a “particulate filter arranged upstream of the SCR catalytic converter and 15
downstream of the nitrogen oxide storage catalytic converter.” As such, there is no
basis or articulated reasoning with some rational underpinning to support the legal
conclusion of obviousness. In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006).
Gandhi further contends that Bandl-Konrad Claim 15 is unpatentable over
Kinugasa ‘024 and Twigg ‘647 because Claim 15 is merely claiming the inherent 20
function of a SCR catalyst as disclosed by Kinugasa ‘024. Again, we are not so
persuaded by Gandhi’s inherency arguments.
To establish inherency, evidence must make clear that the missing
descriptive matter is necessarily present in the thing described in the reference, and
that it would be so recognized by persons of ordinary skill. In re Robertson, 169 25
F.3d 743, 745 (Fed. Cir. 1999); see also Transclean Corp. v. Bridgewood Serv.
Inc., 290 F.3d 1346, (Fed. Cir. 2002). "Inherency . . . may not be established by
56

probabilities or possibilities. The mere fact that a certain thing may result from a
given set of circumstances is not sufficient." Schering Corp. v. Geneva
Pharmaceuticals, 339 F.3d 1373 (Fed. Cir. 2000). Here, Gandhi has the burden to
establish that the limitation of Claim 15 was necessarily present in Kinugasa ‘024
and Twigg ‘647, and he has not done so. Gandhi’s sole reference to the Shin 5
Article to support an assertion that “it was well known in the art that various metal
oxides such as vanadia (V2O5) were effective at catalyzing the oxidation of H2S” is
neither sufficient nor inherent within Gandhi Claim 15. Ex. 1027, Shin Article,
pages 410, 413 (see Table); Ex. 1037, ¶16.
For the reasons discussed above, we hold that Bandl-Konrad has failed to 10
rebut the presumption under 37 C.F.R. §41.207(c) regarding Claims 9, 11-14, and
18 of Bandl-Konrad ‘747 patent, and, as such, Claims 9, 11-14, and 18 of Bandl-
Konrad ‘747 patent are presumed unpatentable over Kinugasa ‘024 and Twigg
‘647. However, we also hold that Bandl-Konrad has established that the
presumption does not apply to Claim 1-8, 10, 15-17 and 20 of Bandl-Konrad ‘747 15
patent.

V. GANDHI SUBSTANTIVE MOTION 1 (PAPER 26) SEEKING
ENTRY OF JUDGMENT AGAINST BANDL-KONRAD BASED ON AN
ALLEGED LACK OF PATENTABILITY UNDER 35 U.S.C. §§ 102 & 103 20

In its Substantive Motion 1 (Paper 26), Gandhi moves for judgment that
Claims 1-19 of Bandl-Konrad ‘747 patent are unpatentable over the prior art under
one or both of 35 U.S.C. §§ 102(e) and 103(a). Gandhi bears the burden of proof
on this matter. 25
In light of our decision regarding unpatentability of Bandl-Konrad Claims 9,
11-14, and 18, we only need to address Gandhi’s motion with respect to Bandl-
Konrad remaining Claims 1-8, 10, 15-17 and 19. With respect to the remaining
57

Claims 1-8, 10, 15-17 and 19 of Bandl-Konrad ‘747 patent in this interference,
Gandhi’s arguments against patentability under 35 U.S.C. § 103(a) can be
summarized as follows:
(1) Bandl-Konrad Claims 1, 4, 5, 7, and 10 would have been
obvious over Gandhi grandparent application, Gandhi ‘470 5
application and Khair ‘096;

(2) Bandl-Konrad Claims 2, 3, 6, 8, 16, 17, and 19 recite
additional well-known limitations and would have been obvious over
Gandhi ‘470 application and Khair ‘096 in view of the knowledge of a 10
skilled artisan as represented by several other prior art references;
16

and

(3) Bandl-Konrad Claim 15 would have been obvious over
Gandhi ‘470 application and an article entitled “Claus Catalysis and 15
H2S Selective Oxidation” by Anne Pieplu (“Pieplu Article”) (Ex.
1014).

catalyst system, shown in Fig. 2, capable of simultaneously eliminating
ammonia emissions and improving net NOx conversion. Gandhi ‘470
application, ¶[0033]. Fig. 2 is reproduced below.

As shown in Fig. 2, the catalyst system includes a lean NOx trap and an 5
NH3-SCR catalyst. As expressly described by Gandhi ‘470 application:
“The advantage of the catalyst system of this invention is
the use of a combination of a lean NOx trap and an NH3-
SCR catalyst. The use of a lean NOx trap in the present
system allows for much greater storage of NOx, because 10
the NOx breakthrough that would otherwise happen can
be controlled by the NH3-SCR catalyst. Additionally, the
use of a lean NOx trap as part of this system allows for
the operation of the engine at lean conditions for a longer
time, and thus provides improved fuel economy . . . . 15
Thus the combination of a lean NOx trap and NH3-SCR
catalyst allows for significant NOx storage and ammonia
production and thus increases net NOx conversion.”

Ex. 1005; Gandhi ‘470 application, ¶[0044] (emphasis added). 20
50. In a preferred embodiment of Gandhi ‘470 application, the combination
of a lean NOx trap and an NH3-SCR catalyst (shown in Fig. 2) is
implemented as an adjacent or alternating lean NOx trap and NH3-SCR
catalyst zones arranged on a single substrate or a single catalytic
converter can, as shown in Figs. 4a-4c (reproduced below). 25
59

Ex. 1005; Gandhi ‘470 application, ¶¶45-47; Figs. 4a-4c.
51. In another preferred embodiment of Gandhi ‘470 application, the
combination of a lean NOx trap and an NH3-SCR catalyst (as shown in
Fig. 2) is implemented as a lean NOx trap washcoat and an NH3-SCR 5
washcoat applied to a single substrate, as shown in Figs. 7a-7c
(reproduced below).

As shown in Figs. 7a-7b, the lean NOx trap washcoat and NH3-SCR
washcoat are formed on the bottom and top layer of a substrate, 10
respectively. In contrast, Fig. 7c involves the use of a one layer washcoat
containing both lean NOx trap and NH3-SCR washcoat formulations. Ex.
1005; Gandhi ‘470 application, ¶¶[0051]-[0052]; Figs. 7a-7c.
52. In the context of the washcoat arrangement shown in Figs. 7a-7c, Gandhi
‘470 application also describes that: 15
60

“The invention also contemplates engineering such
combinations within the pores of the monolithic substrate. An
example of this is incorporating washcoat into porous
substrates used for filtering diesel particulate matter. Thus, this
lean NOx trap/NH3-SCR catalyst concept can be integrated into 5
diesel particulate matter devices.”

Ex. 1005; Gandhi ‘470 application, ¶[0053] (emphasis added).
53. In an alternative embodiment of Gandhi ‘470 application, “three-way”
catalysts are also utilized to improve net NOx conversion, eliminate NH3 10
emissions and reduce catalyst costs, shown in Fig. 9 (reproduced below).

As shown in Fig. 9, a first three-way catalyst 14 is positioned in close
proximity to the engine 12 to reduce cold start emissions; a second three-
way catalyst 16 is modified to enhance the ability of the second three-15
way catalyst 16 to generate NH3 emissions; and an NH3-SCR catalyst 18
is arranged downstream of the second three-way catalyst 16 to store NH3
produced for reaction with NOx emissions in order to reduce both NOx
and NH3 emissions. In other words, a three-way catalyst 14 can be
disposed upstream of a lean NOx trap/NH3-SCR system. Ex. 1005; 20
Gandhi ‘470 application, ¶[0060].

Khair ‘096 Patent
54. Khair, U.S. Patent No. 6,293,096 (“Khair ‘096”) issued on September 25,
2001, and as such, qualifies as prior art under 35 U.S.C. §102(b) against
Bandl-Konrad ‘747 patent. Ex. 1006; Khair ‘096.
55. Khair ‘096 discloses an exhaust gas multiple stage aftertreatment system 5
for reducing the amount of nitrogen oxide (NOx) and particulate matter in
engine exhaust gases, and includes a first stage to oxidize NO to NO2, a
second stage to reduce a portion of NO2 to N2, and a third stage to further
reduce a remaining portion of the NO2 to N2 and oxide carbon to CO2.
Ex. 1006; Khair ‘096, col. 1, ll. 5-12. 10
56. In a first preferred embodiment of Khair ‘096, shown in Fig. 1, the
multiple stage aftertreatment system “effectively combines the functions
of a CRT (catalytically regenerated trap), a LNT (lean NOx trap) and a
carbon trap in a single system for the reduction of both NOx (nitrogen
oxides) and PM (particulate matter) emissions.” Ex. 1006; Khair ‘096, 15
col. 4, ll. 5-9 (emphasis added).
Fig. 1 of Khair ‘096 (annotated version) is reproduced below:

As shown in Fig. 1, the first stage 10 has an inlet 12 adapted to
receive exhaust gases from an internal combustion engine, such as a 20
62

diesel engine, and includes an oxidation catalyst 14 to oxidize
components of the NOx to form nitrogen oxide (NO2) and discharge a
gaseous stream that contains nitrogen oxide (NO2) and particulate matter.
Khair ‘096, col. 2, ll. 42-50; col. 4, ll. 21-37. The second stage 20
contains a lean NOx trap (LNT) 22 to reduce a portion of NO2 to N2 and 5
O2, and a bypass 24. Ex. 1006; Khair ‘096, col. 4, ll. 38-53. The third
stage 30 includes a carbon trap 32 such as a ceramic cordierite wallflow
trap (i.e., particulate filter) to further reduce a remaining portion of the
NO2 to N2 and oxide carbon to CO2. Ex. 1006; Khair ‘096, col. 4, ll. 4-
18. 10
57. According to the first preferred embodiment of Khair ‘096, the carbon
trap 32 or so called “particulate filter” is arranged downstream of the lean
NOx trap 22. Ex. 1006; Khair ‘096, Fig. 1.
58. In a second preferred embodiment of Khair ‘096, as shown in Fig. 2
(annotated version) reproduced below: 15

As shown in Fig. 2, the lean NOx trap 122 and the carbon trap
[oxidizer] 132 are reversed with respect to their respective positions in
the first embodiment shown in Fig. 1. However, the desirable reduction in
63

both NOx and particulate matter in the exhaust emission stream remain
the same relative to Fig. 1. Ex. 1006; Khair ‘096, col. 5, ll. 53-59
(emphasis added).
59. According to the second preferred embodiment of Khair ‘096, the carbon
trap 132 or so called “particulate filter” is arranged downstream of the 5
oxidation catalyst 114 and upstream of the lean NOx trap 122. Ex. 1006;
Khair ‘096, Fig. 2.

Kaneko ‘883
60. Kaneko, U.S. Patent No. 7,127,883 (“Kaneko ‘883”) (Ex. 1013) discloses 10
an exhaust gas purifying apparatus of an internal combustion engine in
which fuel injection is controlled to raise the exhaust gas temperature for
periodically performing a desulfation operation. Ex. 1013; Kaneko ‘883,
col. 15, ll. 23-46.

Pieplu Article
61. Article entitled “Claus Catalysis and H2S Selective Oxidation” by Anne
Pieplu (“Pieplu Article”) (Ex. 1014) discloses that catalysts are used to
oxidize, during a desulfation, hydrogen sulphide (H2S) present in the
exhaust gas and that it was well known in the art that various materials 20
such as activated carbons, zeolites, silica, alumina, and other metal
oxides were effective at catalyzing the oxidation of H2S. Ex. 1014,

Analysis
1.
Bandl-Konrad Claims 1 and 10 as Patentably Distinguishable over Gandhi
‘470 application and Khair ‘096
5
Bandl-Konrad Claim 1 defines an installation for aftertreatment of exhaust
gas generated by a diesel engine of a motor vehicle, said installation comprising:
a nitrogen oxide storage catalytic converter configured for
temporarily storing nitrogen oxides contained in the exhaust gas
during adsorption operating phases with a lean exhaust gas air ratio 10
and, releasing and reducing stored nitrogen oxides during regeneration
operating phases with a rich exhaust gas air ratio;
an SCR catalytic converter arranged downstream of the
nitrogen oxide storage catalytic converter, said SCR catalytic
converter being configured to receive and store ammonia generated by 15
the nitrogen oxide storage catalytic converter, and to reduce nitrogen
oxides in the exhaust gas with the stored ammonia;
a particulate filter arranged upstream of the SCR catalytic
converter and downstream of the nitrogen oxide storage catalytic
converter; and 20
an oxidation catalytic converter arranged as a first exhaust gas
aftertreatment component, as seen in the direction of flow of the
exhaust gas.

Ex. 1003, Bandl-Konrad Claim 1 (emphasis added). 25
Bandl-Konrad Claim 10 depends upon Claim 9 and recites similar
limitations of Claim 1, i.e., “further comprising filtering out particulates in the
exhaust gas with a particulate filter arranged downstream of the nitrogen oxide
storage catalytic converter and guiding filtered exhaust gas to the SCR catalytic
converter.” Ex. 1003, Bandl-Konrad Claim 10 (emphasis added). 30
In order to establish a prima facie case of obviousness, Gandhi must show
that each and every limitation of the claim is described or suggested by the prior art
or would have been obvious based on the knowledge of those of ordinary skill in
65

the art. In re Fine, 837 F.2d 1071, 1074 (Fed. Cir. 1988). However, “rejections on
obviousness cannot be sustained with mere conclusory statements; instead, there
must be some articulated reasoning with some rational underpinning to support the
legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)
cited with approval in KSR International Co. v. Teleflex Inc., 550 U.S. 398, 418 5
(2007).
In Gandhi Substantive Motion 1 (Paper 26), Gandhi acknowledges that
Gandhi ‘470 application does not disclose a separate “particulate filter” component
located between two separate lean NOx trap and SCR catalyst, i.e., a “particulate
filter arranged upstream of the SCR catalytic converter and downstream of the 10
nitrogen oxide storage catalytic converter,” as recited in Bandl-Konrad Claim 1,
and similarly recited in Claim 10. Paper 26, p. 9. Gandhi even admits that Gandhi
‘470 application only discloses filtering in the context of using washcoats into a
porous substrate for filtering particulate matter, shown in Figs. 7a-7c. Ex. 1005;
Gandhi ‘470 application, p. 5, ¶[0053]; Ex. 1001, ¶29; FFs 49-53. 15
Nevertheless, Gandhi, relying solely on Dr. Harold’s testimony, argues that
“it would have been obvious to place a particulate filter between the Lean NOx
Trap and SCR Catalyst taught in Gandhi in view of Khair ‘096” and “it would have
been obvious ... to place an SCR Catalyst downstream of an oxidizing catalyst –
Lean NOx Trap – Particulate Filter configuration disclosed in Khair ‘096 to further 20
remove NOx from the exhaust gas using reductant stored in the SCR Catalyst.”
Paper 29, pp. 9-11; Ex. 1001, ¶¶27-30.
We are not persuaded by Gandhi’s arguments against patentability of Bandl-
Konrad Claims 1 and 10. Nor do we find Dr. Harold’s testimony sufficient in
terms of specific facts as to why a person of ordinary skill in the art would 25
incorporate teachings of Khair ‘096 (Ex. 1006; FFs 54-59) into a catalyst system of
66

Gandhi ‘470 application (Ex. 1005; FF 49-53) in order to arrive at the invention of
Bandl-Konrad Claims 1 and 10 (Ex. 2001; FFs 15-27).
First of all, Gandhi ‘470 application discloses a catalyst system, shown in
Fig. 2, using a combination of a lean NOx trap and NH3-SCR catalyst. Ex. 2001;
Gandhi ‘470 application, ¶44; FF 49. In a first preferred embodiment of Gandhi 5
‘470 application, the combination of a lean NOx trap and a NH3-SCR catalyst is
implemented as alternating lean NOx trap and NH3-SCR catalyst zones arranged on
a single substrate or a single catalytic converter can, shown in Figs. 4a-4c
(reproduced below).
10
Ex. 1005, Gandhi ‘470 application, ¶¶45-47; Figs. 4a-4c; FF 50.
In a second preferred embodiment, the combination of a lean NOx trap and a
NH3-SCR catalyst is implemented as a lean NOx trap washcoat and an NH3-SCR
washcoat applied to a single substrate, shown in Figs. 7a-7c (reproduced below).
67

Ex. 1005; Gandhi ‘470 application, ¶¶51-52; Figs. 7a-7c; FF 51.
In connection with the second preferred embodiment shown in Figs. 7a-7c,
Gandhi ‘470 application already discloses “filtering: in the context of using
washcoats in a porous substrate for filtering particulate matter. As such, we 5
disagree with Dr. Krӧcher’s characterization that:
“it would not be possible to arrange a particulate filter upstream
of the NH3-SCR washcoat and downstream of the lean NOx trap
(LNT) washcoat because the washcoats are not arranged upstream or
downstream from one another, but instead are arranged in layers 10
running parallel to the exhaust gas flow from the engine to the
tailpipe.”

Paper 31, pp. 6-8; Ex. 2009, ¶61; Ex. 2018, ¶31.
15
The dispositive question is whether it would have been obvious for a person
skilled in the art to arrange a particulate filter upstream of the NH3-SCR washcoat
and downstream of the lean NOx trap (LNT) washcoat, shown in Figs. 7a-7c of
Gandhi ‘470 application. On that question, Gandhi has provided no evidence to
support these assertions apart from mere conclusory statements. It is well settled 20
that mere lawyer’s arguments and conclusory statements, which are unsupported
by factual evidence, are entitled to little probative value. In re Geisler, 116 F.3d
1465, 1470 (Fed. Cir. 1997); In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984).
68

Based on this record, we see no reason for one skilled in the art to incorporate any
additional layer of particulate filter as disclosed by Khair ‘096 in the manner
suggested by Bandl-Konrad. Paper 37, pp. 7-11.
With respect to the first preferred embodiment shown in Figs. 4a-4c, Gandhi
‘470 application does not disclose arranging any particulate filter in connection 5
with alternating lean NOx trap and NH3-SCR catalyst zones on a single substrate.
As a secondary reference, Khair ‘096 does not cure the deficiencies of
Gandhi ‘470 application in order to arrive at Bandl-Konrad Claims 1 and 10 and
their respective dependent Claims 2-8, 16-17 and 19. Contrary to Gandhi’s
assertion, Khair ‘096 simply discloses the arrangement of a carbon trap 32, 132 or 10
the so called “particulate filter” either downstream of the lean NOx trap 22 (Ex.
1006; Khair ‘096, Fig. 1) or downstream of the oxidation catalyst 114 but upstream
of the lean NOx trap 122 (Ex. 1006; Khair ‘096, Fig. 2). Khair ‘096 does not
disclose or suggest a separate “particulate filter” component located between a lean
NOx trap and an SCR catalyst, i.e., a “particulate filter arranged upstream of the 15
SCR catalytic converter and downstream of the nitrogen oxide storage catalytic
converter,” as recited in Bandl-Konrad Claim 1, and similarly recited in Claim 10.
Ex. 1006; Khair ‘096, FFs 49-54.
Even if the particulate filter as disclosed by Khair ‘096 can be arranged
either downstream of the lean NOx trap 22 or upstream of the lean NOx trap 122 20
and, as such, can be combined with alternating lean NOx trap and NH3-SCR
catalyst zones on a single substrate, shown in Figs. 4a-4c of Gandhi ‘470
application, we conclude that the combination of Gandhi ‘470 application and
Khair ‘096 still does not arrive at the invention of Bandl-Konrad Claims 1 and 10.
For the foregoing reasons, Gandhi has not met its burden to show that 25
Bandl-Konrad Claims 1 and 10 are unpatentable over Gandhi ‘470 application and
Khair ‘096. Claims 2-8 and 19 depend upon Claim 1, and Claims 16-17 depend
69

upon Claim 10. Accordingly, Bandl-Konrad has not shown that Claims 1-9, 10,
16, 17 and 19 are unpatentable over Gandhi ‘470 application and Khair ‘096.
Even assuming arguendo that Gandhi has met its burden to show that Bandl-
Konrad Claims 1 and 10 are unpatentable over Gandhi ‘470 application and Khair
‘096, we nevertheless agree with Bandl-Konrad’s countervailing arguments and 5
Dr. Krӧcher’s testimony that Gandhi ‘470 application contains numerous
disclosures that would have discouraged one skilled in the art from incorporating a
filter between the disclosed lean NOx trap and NH3-SCR catalytic converter shown
in Figs. 4a-4c. Paper 37, pp. 7-11; Ex. 2018. For example, Dr. Krӧcher testifies
that: 10
First, the Gandhi ‘470 application discloses that it is desirable
to arrange the lean NOx trap and SCR catalytic converter as close as
possible to avoid unwanted conversion of ammonia back to NOx …
Positioning a filter between the catalysts as required by Claim 1
would in fact be discouraged in view of the Gandhi ‘470 application 15
because one skilled in the art would not have desired to reduce the
amount of ammonia and increase the amount of NOx that would occur
due to an increased separation between the lean NOx trap and SCR
catalytic converter (Ex. 2018, ¶37).
20
Second, arranging a particulate filter between the lean NOx trap
and the SCR catalytic converter would have increased the overall cost
of the system because Gandhi discloses that configuring the lean NOx
trap and the SCR catalytic converter on a single substrate significantly
reduces costs. See, e.g., Ex. 1005, Gandhi ‘470 application, ¶ 0056 25
(“the incorporation of both a lean NOx trap and NH3-SCR washcoat
into a single substrate will significantly reduce substrate costs.”).
Indeed, since Gandhi contemplates incorporating the catalysts on a
single substrate, there is no explanation as to how a particulate filter
could be arranged upstream of an SCR catalytic converter and 30
downstream of a NOx catalytic converter in this way. (Ex. 2018, ¶38).

Third, arranging a particulate filter between the lean NOx trap
and the SCR catalytic converter would reduce the amount of NO2
available for the SCR catalytic converter, which would have been 35
70

undesirable because NO2 promotes the operations of the SCR catalytic
converter. The Khair ‘096 patent expressly discloses that the carbon
trap oxidizer 32 reduces the amount of NO2 ... Thus, one skilled in the
art would not have combined the NO2 reducing filter of the Khair
‘096 patent with the catalyst arrangement of the Gandhi ‘470 5
application as the operation of the SCR catalytic converter would be
adversely affected. (Ex. 2018, ¶39).

We are persuaded by Dr. Krӧcher’s testimony that Gandhi ‘470 application
contains disclosures that would have discouraged one skilled in the art from 10
incorporating a filter between the disclosed lean NOx trap and NH3-SCR catalytic
converter shown in Figs. 4a-4c. As such, and based on the disclosures of Gandhi
‘470 application and Khair ‘096, no prima facie case of obviousness can be made
against Bandl-Konrad Claims 1 and 10 under 35 U.S.C. § 103(a).
With respect to Bandl-Konrad remaining Claim 15 which depends on Claim 15
9, via Claim 13, Gandhi further argues that “it would have been obvious to one of
ordinary skill in the art that during a desulfation, hydrogen sulphide (H2S) present
in the exhaust gas would be oxidized in the SCR catalytic converter based on the
chemistry underlying the oxidation of H2S and SCR Catalysts” as evidenced by,
inter alia, Kaneko ‘883 and Pieplu Article. Ex. 1001, ¶¶80-82; FF 60-61. Bandl-20
Konrad has not offered any rebuttal. Therefore, in the absence of Bandl-Konrad’s
opposition, we agree with Gandhi and hold that Gandhi has not shown that Claim
15 is unpatentable under 35 U.S.C. §103(a) over Gandhi ‘470 application, Kaneko
‘883 and Pieplu Article.
25
VI. CONCLUSIONS
Based on the record before us, we conclude that Bandl-Konrad has met its
burden to show by the preponderance of evidence that all Gandhi Claims 9-13, 19,
20, 28, 30-35, and 46-49 of Gandhi’s involved application (Gandhi ‘558
71

application) are unpatentable under 35 U.S.C. §§102, 103 and 112, first paragraph.
Specifically, Bandl-Konrad has shown that: (1) Claims 11-13 and 20 of Gandhi’s
involved application are unpatentable under 35 U.S.C. § 112, first paragraph, as
lacking written description in Bandl-Konrad Motion 3 (Paper 31); and (2)
remaining Claims 9-10, 19, 28, 30-35, and 46-49 of Gandhi’s involved application 5
are unpatentable under 35 U.S.C. §§ 102 and 103 over prior art, including
Kinugasa ‘024 and Twigg ‘647 in Bandl-Konrad Motion 4 (Paper 32).
We also conclude that: (1) Bandl-Konrad has failed to rebut the presumption
under 37 C.F.R. §41.207(c) regarding Claims 9, 11-14, and 18 of Bandl-Konrad
‘747 and, as such, Claims 9, 11-14, and 18 of Bandl-Konrad ‘747 patent are 10
considered unpatentable over the same prior art, including Kinugasa ‘024 and
Twigg ‘647; and (2) Gandhi has not shown that Bandl-Konrad Claims 1-8, 10, 15-
17, and 19 of Bandl-Konrad ‘747 patent are unpatentable over Kinugasa ‘024 and
Twigg ‘647.
We further conclude that Gandhi has not met its burden to show that Bandl-15
Konrad Claims 1-8, 10, 16-17, and 19 are unpatentable over Gandhi grandparent
‘470 application and Khair ‘096. However, Gandhi has shown that Bandl-Konrad
Claim 15 is unpatentable over Gandhi ‘470 application, Khair ‘096 and Pieplu
Article.
As a result of the above decisions, Gandhi no longer has any patentable 20
claims, and Bandl-Konrad remaining Claims 1-8, 10, 16-17, and 19 have not been
shown to be unpatentable. Because there currently is no basis for formulating a
count representing the common patentable subject matter of the parties for
determining priority, it is appropriate to terminate the interference at this point.
Consequently, we need not reach Bandl-Konrad Motion 1 (Paper 29) to substitute 25
new Count and Bandl-Konrad contingent Motion 2 (Paper 30) to re-designate
claims corresponding to the substituted new Count. Therefore, Bandl-Konrad
72

Motion 1 (Paper 29) and Bandl-Konrad contingent Motion 2 (Paper 30) are
DISMISSED.

VII. ORDER
For the reasons discussed above, it is: 5
ORDERED that Bandl-Konrad Motion 3 (Paper 31) alleging lack of
patentability under 35 U.S.C. § 112, first paragraph, as lacking written description
support is GRANTED as to Gandhi Claims 11-13 and 20, but is DENIED as to

30, and 33); 10
FURTHER ORDERED that Bandl-Konrad Motion 4 (Paper 32) alleging
lack of patentability of Gandhi remaining Claims 9-10, 19, 28, 30-35, and 46-49

FURTHER ORDERED that, because Bandl-Konrad did not overcome the
presumption under 37 C.F.R. §41.207(c) that its own claims were unpatentable for 15
the same reasons set forth for Gandhi’s involved claims, and as such, we hold that
Claims 9, 11-14, and 18 of Bandl-Konrad ‘747 patent are also unpatentable under
35 U.S.C. §§ 102 and 103 over the same prior art cited in Bandl-Konrad Motion 4
(Paper 32);
FURTHER ORDERED that Bandl-Konrad overcame the presumption 20
under 37 C.F.R. §41.207(c) as to Claims 1-8, 10, 15-17 and 20 of Bandl-Konrad
‘747 patent;
FURTHER ORDERED that Gandhi Substantive Motion 1 (Paper 26)
alleging lack of patentability under 35 U.S.C. §§ 102 and 103 is GRANTED as to
Claims 9, 11-15, and 18 of Bandl-Konrad ‘747 patent, and is otherwise DENIED 25
as to Claims 1-8, 10, 16, 17, and 19 of Bandl-Konrad ‘747 patent;
73

FURTHER ORDERED that Bandl-Konrad Motion 1 (Paper 29) to
substitute a new Count and Bandl-Konrad contingent Motion 2 (Paper 30) to re-
designate Claims 1-14 and 16-18 of Bandl-Konrad ‘747 patent and Claims 9, 10,
30-35, and 46-49 of Gandhi ‘558 application as corresponding to the substitute
new Count are DISMISSED as MOOT; 5
FURTHER ORDERED that judgment be entered under 37 CFR § 41.127
against the subject matter of all Gandhi Claims 9-13, 19, 20, 28, 30-35, and 46-49
of Gandhi’s involved application, and Bandl-Konrad Claims 9, 11-15, and 18 of
Bandl-Konrad ‘747 patent in a separate paper;
FURTHER ORDERED that a copy of this decision shall be entered into 10
the files of Bandl-Konrad’s involved patent, U.S. Patent No. 7,814,747 and
Gandhi’s involved application, U.S. Patent Application No. 12/706,558.

JUDGMENT – 37 CFR §41.127(a)
2

A decision of the Board on motions has been issued holding: (1) Gandhi’s
Claims 11-13 and 20 are unpatentable under 35 U.S.C. § 112, first paragraph, for
lack of written description support from Gandhi’s involved application; (2)
Gandhi’s remaining Claims 9, 10, 19, 28, 30-35, and 46-49 are unpatentable over
prior art; and (3) Bandl-Konrad Claims 9, 11-15, and 18 of Bandl-Konrad ‘747 5
patent are unpatentable over prior art. Paper 125. Without any patentable claims
from Gandhi, there is no basis for formulating a count representing the common
patentable subject matter of the parties for determining priority. It is appropriate,
therefore, to terminate the interference at this point and enter judgment.
For the reasons discussed above, it is: 10
ORDERED that Junior Party, Bandl-Konrad Claims 9, 11-15, and 18
(corresponding to Count 1) of Bandl-Konrad ‘747 patent will be cancelled pursuant
to 35 USC §135(a);
FURTHER ORDERED that all Gandhi Claims 9-13, 19, 20, 28, 30-35, and
46-49 (corresponding to Count 1) of Gandhi’s involved application (Gandhi ‘588 15
application) are finally refused pursuant to 35 USC §135(a);
FURTHER ORDERED that a copy of this judgment be made of record in
the files of Bandl-Konrad’s involved patent, U.S. Patent No. 7,814,747 and
Gandhi’s involved application, U.S. Patent Application No. 12/706,558;
FURTHER ORDERED that if there is any settlement agreement or related 20
documents which have not been filed, attention is directed to 35 U.S.C. §135(c)
and 37 C.F.R. §41.205.
