INTRODUCTION
On June 23, 2014, First Quality Baby Products, LLC (“Petitioner”)
filed a Petition (Paper 1, “Pet.”) requesting inter partes review of claims 1–
24 of U.S. Patent No. 8,747,379 B2 (Ex. 1001, “the ’379 patent”).
Kimberly-Clark Worldwide, Inc. (“Patent Owner”) timely filed a
Preliminary Response (Paper 6). An inter partes review of all challenged
claims was instituted on December 15, 2014. Paper 9 (“Inst. Dec.”). After
institution, Patent Owner filed a Patent Owner’s Corrected Response (Paper
14, “PO Resp.”), and Petitioner filed a Petitioner’s Reply (Paper 19, “Pet.
Reply” (redacted public version); Paper 20 (filed under seal)).

We have jurisdiction under 35 U.S.C. § 6(c). This Final Written
Decision is issued pursuant to 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73. As
discussed below, Petitioner has shown by a preponderance of the evidence
that claims 1–24 of the ’379 patent are unpatentable.
A. Related Proceedings
The parties identify several matters related to this proceeding: (1) a
district court case in the Eastern District of Wisconsin (Case No. 1:14-cv-

A combined oral hearing was held for this case as well as related inter
partes reviews IPR2014-01023 and IPR2014-01024. Although the parties at
times referred to specific claims at issue in only one of these cases, many of
the substantive issues also are present in all three cases and, as such, the
parties’ statements at the oral hearing are applied to each of the related cases
as appropriate.

01466-WCG), in which Patent Owner has asserted the ’379 patent against
Petitioner; (2) an inter partes reexamination (Reexamination Control No.
95/001,228) filed by Petitioner addressing claims 1–10 of the ’379 patent, as
well 77 additional claims added during the reexamination; (3) First Quality
Baby Prods., Inc. v. Kimberly-Clark Worldwide, Inc., Case IPR2014-01023
(PTAB), filed by Petitioner on June 23, 2014, and instituted on December
15, 2014, in which Petitioner challenges claims 33–54 of the ’379 patent;
and (4) First Quality Baby Prods., Inc. v. Kimberly-Clark Worldwide, Inc.,
Case IPR2014-01024 (PTAB), filed by Petitioner on June 23, 2014, and
instituted on December 15, 2014, in which Petitioner challenges claims 25–
32 of the ’379 patent. Paper 54, 1; Paper 56, 2–3.
Petitioner also identifies a district court case filed by Patent Owner in
the Eastern District of Wisconsin (Case No. 09-cv-0916-WCG),
consolidated with another case in the same district (Case No. 10-cv-1118), in
which claims of a related patent, U.S. Patent No. 6,849,067, were asserted
against Petitioner. Paper 56, 1–2.
B. The ’379 Patent
The ’379 patent relates to disposable absorbent training pants. Ex.
1001, 1:17–20. The training pants include a fastening system whereby the
training pants can be fastened together, unfastened, and then refastened. Id.
at 1:65–2:2, 2:37–39. The fastening components are disposed along the
sides of the training pants, and the side panels may incorporate elastomeric
material for enhanced fit and comfort. Id. at 2:2–8. The fastening
components disposed on the back side panels releasably engage mating
fastening components on the front side panels. Id. at 2:29–33.

Petitioner challenges claims 1–24 of the ’379 patent. Claim 1, set
forth below, is the only independent claim challenged by Petitioner, and is
illustrative of the challenged claims.
1. A training pant for use in training a child to use the toilet,
comprising:
an absorbent chassis defining a longitudinal axis, a transverse
axis, an overall length dimension parallel to the longitudinal
axis, front and back waist edges parallel to the transverse
axis, opposite side edges extending between the front and
back waist edges, a front waist region contiguous with the
front waist edge, a back waist region contiguous with the
back waist edge, and a crotch region which extends between
and interconnects the front and back waist regions, the
absorbent chassis comprising:

toward a longitudinal end of the training pant, and a leg
end edge extending from the respective side edge of the
composite structure to the distal edge and disposed
toward the longitudinal center of the training pant, the
front side panels having an average length dimension that
is about 20 percent or greater of the overall length
dimension of the absorbent chassis;
first and second back side panels bonded to the composite
structure in the back waist region and longitudinally
spaced from the first and second front side panels, each
back side panel having a distal edge, an interior portion

training pant, the back side panels having an average
length dimension that is about 20 percent or greater of
the overall length dimension of the absorbent chassis, an
elastomeric material disposed between nonwoven facing
layers in at least the interior portion of each back side
panel to render each back side panel elastomeric in a
direction generally parallel to the transverse axis; and
a fastening system for releasably securing the absorbent
chassis in a pant-like configuration having a waist
opening and a pair of leg openings, the fastening system
comprising first and second fastening components
adapted to releasably engage first and second mating
fastening components, the first and second fastening
components being disposed on the respective first and
second back side panels adjacent the distal edges, the
first and second mating fastening components being
disposed on the respective first and second front side
panels adjacent the distal edges, the fastening
components and the mating fastening components each
comprising mechanical fasteners, and engagement of the
fastening components and mating fastening components
defines refastenable seams that cover about 80 to 100

ANALYSIS
A. Claim Construction
In an inter partes review, claim terms in an unexpired patent are
construed according to their broadest reasonable interpretation in light of the
specification. 37 C.F.R. § 42.100(b); see In re Cuozzo Speed Techs., LLC,
793 F.3d 1268, 1278–79 (Fed. Cir. 2015). Only those terms in controversy
need to be construed, and only to the extent necessary to resolve the
controversy. Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803
(Fed. Cir. 1999).
During trial, the parties disputed the claim constructions of the terms
“prefastened” and “non-stretchable,” which we address below. No other
claim terms require express construction to resolve the issues raised in this
inter partes review.
1. prefastened

Patent 8,747,379 B2

7
Claim 16 recites, “wherein the training pant is prefastened to provide
a pant-like product for the user.” Patent Owner argues this phrase should be
construed as “a training pant having side panels with mating fastening
components thereon in which the fastening components are fastened or
otherwise connected during manufacture and prior to sale such that the user
is provided with a pant-like product.” PO Resp. 19, 27, 45. In support of
this position, Patent Owner relies solely on the testimony of its declarant,
G.A.M. (Tony) Butterworth. Id. (citing Ex. 2006 ¶¶ 48, 101). Petitioner
argues Patent Owner’s proposed construction is overly narrow and contends
“prefastened” only requires that the training pant be fastened prior to being
put on a child rather than during manufacturing. Pet. Reply 19–20.
As Petitioner asserts, the intrinsic evidence does not support the
construction advanced by Patent Owner. The ’379 patent explains that the
claimed training pants “can further include releasable side bonds . . . for
improved reliability of maintaining the pant in a prefastened condition
particularly when it is being pulled on or off over the hips of the wearer.”
Ex. 1001, 20:1–4. In addition, the specification states: “The absorbent
articles are desirably pre-fastened to provide a pant-like product for the user.
The product can then be pulled on like a conventional training pant . . . .”
Id. at 5:31–34. The specification does not describe any manufacturing
process for prefastening training pants. Mr. Butterworth’s testimony is
based solely on claim language indicating that the recited fastening
components and mating fastening components are the elements that are
prefastened. Ex. 2006 ¶ 48. His conclusion, however, is not supported by
that claim language, which does not reference manufacturing or a timeframe
prior to sale. See Ex. 1014, 99:13–16, 102:25–103:9 (Mr. Butterworth
indicating at his deposition that the ’379 patent does not discuss a
IPR 2014-01021
Patent 8,747,379 B2

8
manufacturing process for prefastening the claimed training pant, or when
the training pants are prefastened).
6

Based on the record presented, the broadest reasonable interpretation
of “prefastened” in light of the specification requires that the claimed
training pant be fastened prior to wear, but does not require fastening during
manufacturing or prior to sale.
2. non-stretchable
Claim 18 recites, “wherein the front side panels are non-stretchable.”
Patent Owner argues that “non-stretchable” is not synonymous with “non-
elastomeric” or “non-elastic.” PO Resp. 48–49. In support of its position,
Patent Owner relies on the testimony of Mr. Butterworth, who testified:
The terms “nonstretchable” and “non-elastomeric” have
different meanings. A non-elastomeric material includes a
material that is capable of stretching (i.e., elongating) but does
not generally return to its original shape. A non-stretchable
material, as recited in claim 18, is not capable of elongating. . . .
[O]ne of ordinary skill in the art would appreciate the difference
between a non-elastic material and a non-stretchable material.
They are not the same thing. As mentioned above, a non-
stretchable is not capable of elongating whereas a non-elastic
material can elongate.
Ex. 2006 ¶¶ 110–11.
The parties appear to agree that an elastomeric/elastic
7
material would
have been understood by a person of ordinary skill to be a material that can

6
Mr. Butterworth’s deposition transcript also was filed in related cases
IPR2014-01023 and IPR2014-01024. Although his testimony at times refers
to specific claims at issue in only one of these cases, the parties do not
dispute that his testimony is applicable across all three cases to the extent he
addresses substantive issues present in all three cases.
7
Both parties use “elastomeric” and “elastic” interchangeably. Tr. 30:12–
23; PO Resp. 48–49.
IPR 2014-01021
Patent 8,747,379 B2

9
stretch, i.e., elongate, but which subsequently returns to its original shape.
See, e.g., PO Resp. 48; Tr. 30:12–23. Thus, non-elastomeric/non-elastic
materials would have been understood to include materials that cannot
elongate as well as materials that can elongate but do not subsequently
return to their original shape. See, e.g., PO Resp. 48; Tr. 30:12–31:14. The
parties do not appear to dispute that “stretchable” materials are able to
elongate, whereas “non-stretchable materials” cannot. See, e.g., PO Resp.
48; Tr. 30:12–23. Thus, although the terms “non-stretchable” and “non-
elastomeric” overlap, they are not synonymous. The parties do not identify
any portion of the specification inconsistent with these interpretations.
Based on the evidence and arguments presented, the broadest
reasonable interpretation of “non-stretchable” is “unable to elongate.” As
noted above, some non-elastomeric/non-elastic materials also may be non-
stretchable, but some are not. Further, claim 24 recites, “wherein the front
side panels do not comprise elastic materials.” Based on the record before
us, the broadest reasonable interpretation of “elastic materials” is “materials
that can elongate and subsequently return to their original shape.”
B. Asserted Grounds of Unpatentability
Petitioner asserts that claims 1–10, 12, 13, 15–17, and 19–23 are
unpatentable under § 103 in view of the combination of Brandon and
Anderson. Pet. 16–35. With respect to claims 11, 14, 18, and 24, Petitioner
asserts unpatentability under § 103 in view of the combination of Brandon,
Anderson, and Long. Id. at 35–45.

demonstrated by a preponderance of the evidence that all challenged claims
are unpatentable on the grounds asserted.
9

1. Brandon
Brandon is a published PCT patent application filed by Patent Owner,
which relates to the manufacturing of disposable absorbent articles such as
training pants. Ex. 1002, 1, 3. U.S. Patent No. 4,940,464 (Ex. 1110, “Van
Gompel”) is incorporated into Brandon’s disclosure by reference. Id. at 7.
Examples of the training pants disclosed in Brandon are shown in Figures 1,
2, and 2A, reproduced below:

9
Both parties agree that a person of ordinary skill in the art would have had
two to four years of work experience in product design and testing of
disposable absorbent articles, such as diapers and training pants. Pet. 15; PO
Resp. 6. We adopt this characterization and apply it to our analysis.
IPR 2014-01021

11

Figures 1 and 2 show front views of disposable absorbent articles (training
pants 10 and 40) disclosed in Brandon. Id. at 5, 11–13. Figure 2A shows
the same article shown in Figure 2 in a partially disassembled state. Id. at 5.
The depicted training pants include front panel 12, back panel 14,
crotch panel 16 interconnecting the front and back panels, leg elastics 30,
and elastic side panels 18 joined to front panel 12 and back panel 14. Id. at
11–12. Each elastic side panel 18 is made of two separate elastic portions,
which may be joined together by ultrasonic bonding to form side seam 20.
Id. at 11. An absorbent pad also may be included, positioned between a
liquid impermeable outer cover and a liquid permeable liner. Id.
IPR 2014-01021
Patent 8,747,379 B2

12
2. Anderson
Anderson relates to a disposable training panty. Ex. 1006, 2:47–51.
An embodiment of the disclosed training panty is depicted in Figures 1 and
2, reproduced below:

Figure 1 shows a perspective view of Anderson’s disposable training panty,
fully opened to show the inside of the panty and depicting the use of Velcro
to secure the sides together. Id. at 3:17–20. Figure 2 shows Anderson’s
training panty as viewed on a child wearing the panty. Id. at 3:21–22.
Side 22 can be joined with side 24 using velcro 18 to form releasable
side seam 29. Id. at 4:27–32. Similarly, sides 26 and 28 can be joined to
form the other releasable side seam. Id. Thus, the side seams are secured to
approximate the side seams of a normal underpant, but the seams are readily
releasable in the event of an accident to facilitate removal of the panty
without undue contamination. Id. at 4:32–37.
IPR 2014-01021
Patent 8,747,379 B2

13
3. Long
Long relates to fastening systems for garments, such as disposable
absorbent articles. Ex. 1007, 1:6–43. Such an article may have side panels
that attach using mechanical fasteners, such as a hook layer configured to
engage a loop material. Id. at 2:45–61, Fig. 1. The side panels may be
composed of “a substantially non-elastomeric material, such as polymer
films, woven fabrics, nonwoven fabrics or the like, as well as combinations
thereof.” Id. at 13:18–21. Long also discloses the use of a “surge
management portion” and elastic containment flaps, in conjunction with
absorbent structures and other elements, to manage liquids introduced into
the absorbent article. Id. at 4:53–65, 10:30–50, 11:63–12:16. U.S. Patent
No. 4,704,116 (Ex. 1112, “Enloe”) is incorporated into Long’s disclosure by
reference. Id. at 12:2–5.
4. Claim 1
Petitioner contends Brandon (including the disclosures of Van
Gompel incorporated by reference) teaches all of the limitations of claim 1,
except the recited fastening system for releasably securing the absorbent
chassis. Pet. 20–21, 26–30. For example, Petitioner identifies Brandon’s
teachings of front waist edge 118, front panel 12, back waist edge 118, back
panel 14, and crotch panel 16, as teaching the recited front waist edge, front
waist region, back waist edge, back waist region, and crotch region,
respectively. Id. at 26. Petitioner asserts that Brandon’s disclosures of an
absorbent pad, its associated structures and materials, outer cover graphics,
and leg elastic 30, collectively, teach the elements of the “composite
structure” recited in claim 1. Id. at 26–28. In addition, Petitioner cites
Brandon’s disclosures relating to elastic side panels 18, including Van
Gompel’s disclosures of certain dimensions and materials composition, as
IPR 2014-01021
Patent 8,747,379 B2

14
teaching the recited front and back side panels of claim 1. Id. at 28–30. The
Petition notes the similarities between, for example, Figure 2 of the ’379
patent and Figure 2A of Brandon (Pet. 20–21):

’379 Patent

Brandon

Figure 2 of the ’379 patent depicts an embodiment of the claimed disposable
absorbent article in an unfastened, laid flat condition. Ex. 1001, 8:29–32.
Figure 2A of Brandon similarly depicts a disclosed disposable absorbent
article in a partially disassembled, stretched flat state. Ex. 1002, 5. Patent
Owner does not dispute that Brandon teaches these aspects of claim 1.
With respect to the fastening system of claim 1, Petitioner contends
the combination of Brandon and Anderson teaches each limitation. Pet. 21–
25, 30–31. Specifically, Petitioner argues a person of ordinary skill would
have been led to replace the bonded side seams of Brandon with the
IPR 2014-01021
Patent 8,747,379 B2

15
refastenable side seams disclosed in Anderson. Id. According to Petitioner,
velcro 18 on back side panels 24 and 28 in Anderson teach the first and
second fastening components of claim 1 of the ’379 patent, and
corresponding velcro 18 on the front side panels 22 and 26 teach the first
and second mating fastening components. Id. at 31. Petitioner also asserts
that Brandon’s bonded seams and Anderson’s refastenable seams are each
disclosed as covering 80–100% of the distance between the waist and leg
openings of their respective training pants. Id. at 24.
Patent Owner contends, however, that the combination of Brandon
and Anderson fails to teach the requirement that “engagement of the
fastening components and mating fastening components defines refastenable
seams that cover about 80 to 100 percent of a distance between the waist
opening and the leg openings,” as recited in claim 1. PO Resp. 28–31 (citing
Ex. 2006 ¶¶ 65–70). Petitioner replies that Patent Owner’s proffered expert,
Mr. Butterworth, admitted that Brandon teaches a bonded seam extending
100% of the distance between the waist and leg openings, and that it was
well known in the art to provide such a seam. Pet. Reply 11–12 (citing Ex.
1014, 81:22–82:22, 85:3–8).
10

10
Petitioner argues that many of Patent Owner’s arguments are collaterally
estopped based on a district court decision involving the validity of a related
patent. E.g., Pet. Reply 3–6 (citing Ohio Willow Wood Co. v. Alps South,
LLC, 735 F.3d 1333, 1342 (Fed. Cir. 2013)). Petitioner also notes that the
district court in a related case addressing the ’379 patent recently entered
summary judgment of invalidity against Patent Owner based on collateral
estoppel. See Ex. 1034, 4–11. We need not reach the issue of collateral
estoppel, however, because we conclude a preponderance of the evidence
establishes that the challenged claims are unpatentable even considering
Patent Owner’s arguments.
IPR 2014-01021
Patent 8,747,379 B2

16
Based on the full record after trial, the evidence presented supports
Petitioner’s view. It is undisputed that Brandon teaches a seam extending
100% of the distance between the waist and leg openings. See Tr. 44:13–15;
Ex. 1014, 82:15–22. The record also indicates it was well known in the art
generally to provide 80–100% seams. Ex. 1014, 85:3–8; Ex. 1021 ¶ 99.
Although Patent Owner disputes that Anderson teaches an 80–100% seam,
such an express disclosure is not required given Brandon’s disclosure of a
100% seam. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test
for obviousness is not whether the features of a secondary reference may be
bodily incorporated into the structure of the primary reference; nor is it that
the claimed invention must be expressly suggested in any one or all of the
references. Rather, the test is what the combined teachings of the references
would have suggested to those of ordinary skill in the art.”). Moreover,
Petitioner argues persuasively that a person of ordinary skill would have
understood Anderson also to teach an 80–100% seam because such a seam
was known to be important to prevent undesired tearing or separation, and to
best approximate a normal underpant. Pet. Reply 11–13; see Ex. 1006,
2:35–36, 4:32–37, Fig. 2; Ex. 1014, 83:14–23, 85:3–20; Ex. 1021 ¶¶ 99,
101, 102, 104, 106, 107.
11
In sum, Petitioner has established sufficiently
that the combination of Brandon and Anderson teaches or suggests each
limitation of claim 1.

11
Patent Owner also argues that Petitioner failed to articulate sufficiently its
arguments and supporting evidence regarding the 80–100% limitation in the
Petition. Tr. 36:8–24. We disagree. See Pet. 24, 30–31. Moreover, we
determine that Petitioner’s Reply was properly responsive to the arguments
and evidence presented in Patent Owner’s Response, and did not introduce
new theories or improper arguments on this issue.
IPR 2014-01021
Patent 8,747,379 B2

17
Petitioner asserts that a person of ordinary skill would have been led
to combine the training pants of Brandon with the refastenable seam of
Anderson because the references identify solutions for the same problem,
namely potential contamination on the child when removing soiled training
pants. Pet. 22–24 (citing KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 419–
20 (2007)). The record supports Petitioner’s position. Brandon states that
“side seams 20 may be constructed to be manually tearable in order to allow
training pant 10 to be disassembled manually by the caregiver, so that it can
be easily removed from the child after a bowel movement.” Ex. 1002, 11.
Anderson discloses that training pants with tearable seams “facilitate
removal of the panty after the child has either a bowel accident or a bladder
accident,” which reduces “incidents of contamination on the child and in the
area surrounding the child.” Ex. 1006, 1:46–55. Anderson further teaches
refastenable side seams, as discussed above, explaining that “in the event of
an accident the [refastenable] seams are readily released to facilitate removal
of the panty without undue contamination.” Id. at 4:32–37.
Patent Owner contends, however, that a person of ordinary skill would
not have been motivated to combine Brandon and Anderson in the manner
asserted by Petitioner because both Brandon and Anderson teach away from
such a combination. PO Resp. 31–39. First, Patent Owner argues Brandon
teaches that training pants should be designed to feel different than diapers
to facilitate toilet training, but that replacing its bonded seams by adding
refastenable seams such as in Anderson contradicts that goal by making the
training pants resemble diapers. Id. at 32–35. The evidence of record,
however, belies that argument. As Petitioner notes (Pet. Reply 13),
Anderson discloses explicitly that its refastenable seams “approximate the
side seams of a normal underpant” (Ex. 1006, 4:27–34), and notes the

importance of training pants that “look like a normal panty when first put on
by the child” (id. at 2:35–36).
Next, Patent Owner argues Anderson teaches away from the asserted
combination with Brandon because Anderson teaches away from using its
releasable fastening system with a liquid impermeable outer cover, as taught
by Brandon and required by claim 1. PO Resp. 35–39. Patent Owner is
correct that Anderson discloses advantages to constructing training pants to
allow some moisture to leak through the outer cover. See, e.g., Ex. 1006,
3:40–49 (explaining that a preferred embodiment of Anderson includes a
“moisture permeable outer covering” that facilitates toilet training by
alerting the child to a bowel or bladder accident). According to Patent
Owner, Anderson discloses the use of refastenable seams because they
facilitate removal while minimizing contamination, which is only necessary
due to the moisture permeable covering. See PO Resp. 37–38. Patent
Owner’s position is unpersuasive, however, because merely describing the
benefits of a moisture permeable cover does not teach away from using an
impermeable cover. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004);
In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). At the oral hearing, Patent
Owner also admitted that nothing in the record indicates a person of ordinary
skill would have been led to avoid training pants that do not allow moisture
to leak through the outer cover. See Tr. 61:21–62:6; see also Ex. 1014,
339:10–18 (Mr. Butterworth testifying that Anderson does not disparage the
use of refastenable seams with liquid permeable outer covers). Based on the
full record after trial, Petitioner has established sufficiently a reason with
rational underpinning to combine Brandon and Anderson. See KSR, 550
U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)).
IPR 2014-01021
Patent 8,747,379 B2

19
Consequently, a preponderance of the evidence supports Petitioner’s
position that claim 1 of the ’379 patent is unpatentable as obvious in view of
the combination of Brandon and Anderson.
5. Claims 2, 3, 5–7, 10, 12, 13, 15, 17, 19–21, and 23
Petitioner asserts that claims 2, 3, 5–7, 10, 12, 13, 15, 17, 19–21, and
23, which depend from claim 1, also would have been obvious to a person of
ordinary skill in light of the combined teachings of Brandon and Anderson.
See Pet. 25–26, 31–35. Patent Owner does not argue the patentability of
these claims separately, relying instead on its arguments for claim 1, which
are addressed above. Based on the full record after trial and the arguments
presented by the parties, a preponderance of the evidence supports
Petitioner’s contentions that these dependent claims are unpatentable as
obvious in view of the combination of Brandon and Anderson.
6. Claim 4
Claim 4 of the ’379 patent depends from claim 3 and further recites,
“wherein the first and second fastening components are sized larger than the
first and second mating fastening components.” Petitioner cited Gardner v.
TEC Systems, Inc. to argue that claim 4 is obvious because “the only
difference between the prior art and [claim 4] is the recitation of relative
dimensions, and a device having the claimed dimensions would not perform
differently than the prior art.” Pet. 25 (citing 725 F.2d 1338 (Fed. Cir. 1984)
(en banc)) (emphases omitted). In Gardner, the Federal Circuit affirmed a
district court’s decision invalidating claims where “the dimensional
limitations did not specify a device which performed and operated any
differently from the prior art.” 725 F.2d at 1349.
Patent Owner argued in its Response that Gardner does not compel a
conclusion of obviousness because the Petition failed to provide sufficient
IPR 2014-01021
Patent 8,747,379 B2

20
analysis, and applied Gardner incorrectly as a per se rule. PO Resp. 41–43
(citing Ex Parte Goodrich, Case No. 2009-009437, 2010 WL 3441066
(BPAI Aug. 30, 2010) (non-precedential)). Relying on Mr. Butterworth’s
Declaration, Patent Owner asserted that the relative size limitation of claim 4
provides enhanced functionality—i.e., adjustability and better coverage of
fastening surfaces to prevent abrasions—rebutting Petitioner’s argument that
the recited size relationship does not result in different performance. Id. at
41 (citing Ex. 2006 ¶¶ 95–96).
Subsequent to the Patent Owner Response, Petitioner deposed Mr.
Butterworth. Ex. 1014. Mr. Butterworth provided the following testimony
at his deposition:
[Q.] So in -- in December of 1998, is it correct that a person of
ordinary skill in the art would have the general understanding
that a training pant having one set of fasteners larger than the
other would allow for adjustability?
* * *
THE WITNESS: I believe that would be the case because
when you make one mating surface larger than the other most
people recognize that that means that the target can be adjusted.
* * *
Q. Well, were fasteners -- prior to December 1997 were
training pants having fasteners sized larger than their mating
pairs of fasteners known in the prior art?
A. They probably were.
Id. at 151:2–13, 152:10–14. Relying on this testimony, Petitioner in its
Reply argued that claim 4 is obvious because Mr. Butterworth admitted the
recited size limitation and its benefits were known in the prior art. Pet.
Reply 17. Petitioner also alleged that Mr. Butterworth admitted the relative
IPR 2014-01021
Patent 8,747,379 B2

21
size limitation of claim 4 is “not critical to the claims of the ’379 Patent,”
asserting that this alleged admission supports its argument that claim 4 is
obvious under Gardner. Id. at 17–18 (citing Ex. 1014, 149:20–150:23).
At the oral hearing, Patent Owner acknowledged Mr. Butterworth’s
deposition testimony (Tr. 54:1–16), but argued the testimony should be
disregarded because neither Mr. Butterworth nor Patent Owner had fair
notice of Petitioner’s arguments or an adequate opportunity to present
counterevidence—for example, regarding possible teaching away (e.g., Tr.
54:19–55:9). We disagree. As an initial matter, Patent Owner is correct that
the Petition does not include specifically an allegation that the size limitation
was known generally in the art, and does not present evidence of that fact.
Such evidence, however, was introduced into the record through discovery
in the form of Mr. Butterworth’s deposition testimony. Patent Owner does
not advance persuasively any reason to block Petitioner from relying on this
evidence, which could not have been cited in the Petition because Mr.
Butterworth’s deposition had not yet occurred.
12
In essence, Patent Owner
requests that the Board prevent Petitioner from using evidence in the record
it admits is inconsistent with its position on patentability, and which its own
expert provided to Petitioner during discovery. We decline to do so.
Nor are we persuaded by Patent Owner’s protestations of prejudice.
Although Patent Owner asserts Mr. Butterworth was not given a fair
opportunity to “prepare” for Petitioner’s questions, Patent Owner proffered
him as an expert in this field and otherwise relies on his testimony regarding

12
Although Petitioner’s position would have been stronger had it provided
similar evidence with the Petition, the fact remains that the record includes
Mr. Butterworth’s testimony, which was routine discovery provided in the
normal course of this inter partes review. See 37 C.F.R. § 42.51(b)(1)(ii).
IPR 2014-01021
Patent 8,747,379 B2

22
similar issues. See, e.g., PO Resp. 33–35 (citing Ex. 2006 ¶¶ 74–77 (Mr.
Butterworth’s declaration testimony regarding “the conventional wisdom in
the industry at the time of the invention”)). The testimony relied on by
Petitioner was provided in response to basic questions about the
understanding of a person of ordinary skill in the art and whether the recited
limitation was known in the art at the time of the invention. Ex. 1014,
151:2–13, 152:10–14. Moreover, the Petition plainly raised the issue of
whether any alleged functionality of the limitations of claim 4 already was
known to be provided by the prior art. Pet. 25. Petitioner’s questioning of
Mr. Butterworth on this issue should not have been unexpected considering
he provided testimony on the subject in his Declaration, which Patent Owner
submitted with its Response. See Ex. 2006 ¶ 95; PO Resp. 41.
Patent Owner does not dispute the veracity of Mr. Butterworth’s
testimony. Further, Patent Owner does not argue that he misunderstood the
questions (Tr. 53:18–24), and did not move to exclude the testimony.
13

Patent Owner had the opportunity to adduce further testimony from Mr.
Butterworth at his deposition to clarify or supplement his testimony, but it
did not do so with respect to the testimony at issue. See Tr. 57:12–58:8. No
attempt was made to seek relief from the Board or to introduce further
information into the record (e.g., a supplemental declaration or additional
briefing). See Tr. 59:18–60:6. Patent Owner made no request to have Mr.

13
Patent Owner properly raised at the oral hearing the issue of whether
Petitioner’s arguments should be disregarded as improper new arguments,
rather than raising the issue in a motion to exclude. See Tr. 58:9–59:2. That
is a distinct issue, however, from whether Mr. Butterworth’s cross-
examination testimony should be excluded as inadmissible because it is
allegedly misleading or incomplete. In any event, we also conclude
Petitioner’s arguments were not improper.
IPR 2014-01021
Patent 8,747,379 B2

23
Butterworth testify at the oral hearing, or to secure any other opportunity for
him to provide the additional testimony or evidence that Patent Owner
asserts was prevented unfairly. See id. In these circumstances, we conclude
that Petitioner’s reliance on Mr. Butterworth’s testimony is not improper,
and that Patent Owner was not unfairly prejudiced.
Based on Mr. Butterworth’s testimony, which we find credible, the
record indicates that the limitations of claim 4 were known and obvious to
one of ordinary skill in the art. Additionally, the record supports Petitioner’s
argument that the size limitations of claim 4 do not distinguish the claim
from the prior art, which ordinary artisans knew to provide the benefit of
adjustability, as Mr. Butterworth testified. See Gardner, 725 F.2d at 1349.
Petitioner’s contentions are further supported by the evidence indicating this
alleged benefit was not a critical aspect of the claimed invention. See In re
Woodruff, 919 F.2d 1575, 1578 (Fed. Cir. 1990) (“These cases [including
Gardner] have consistently held that in such a situation, the applicant must
show that the particular range is critical, generally by showing that the
claimed range achieves unexpected results relative to the prior art range.”).
Consequently, considering the full record after trial, a preponderance of the
evidence supports Petitioner’s contention that claim 4 would have been
obvious in view of the combination of Brandon and Anderson.
7. Claims 8, 9, and 22
Claim 8 of the ’379 patent depends from claim 7 (which depends from
claim 1), and further recites, “wherein the mating fastening components
have a length-to-width ratio of about 5 or greater.” Claim 22 also depends
indirectly from claim 1, and further recites, “wherein the fastening
components and the mating fastening components have a length-to-width
ratio of about 5 or greater.” Petitioner relies on Gardner, arguing that these
IPR 2014-01021
Patent 8,747,379 B2

24
“length-to-width ratio” limitations do not distinguish the claims from the
prior art. Pet. 25; Pet. Reply 18–19.
In support of its arguments, Petitioner cites Mr. Butterworth’s
deposition testimony in which he acknowledges that the ’379 patent
specification describes ratios other than 5 or greater—and, specifically, a
ratio of 2 or greater—as desirable. See Ex. 1014, 153:14–154:17; Ex. 1001,
17:9–12. In addition, Petitioner cites Mr. Butterworth’s testimony that the
’379 patent does not describe any “benefits” of a ratio of 5 or greater
compared to, for example, a ratio of 2 or greater. See Ex. 1014, 156:12–23.
Based on this testimony, Petitioner contends claims 8 and 22 are
unpatentable under Gardner because the recited size limitation does not
provide any particular benefits and, thus, is not “critical” to the invention.
Pet. Reply 18–19; see Woodruff, 919 F.2d at 1578. Petitioner’s arguments
are persuasive and are supported by the record.
Patent Owner contends that, in fact, the recited ratio of claims 8 and
22 provides benefits over the prior art. PO Resp. 43–44. For example,
Patent Owner asserts that the recited ratio “preserves the elasticity of the
side panel” and “aids in the flexibility of the fastener.” Id. at 44 (citing Ex.
2006 ¶ 99). These contentions are not persuasive, however, because Patent
Owner does not identify evidence indicating these are improvements over
the prior art. See Gardner, 725 F.2d at 1345–46 (focusing on whether the
claimed size limitations “result in differences in performance over the prior
art”). The only support in the record cited by Patent Owner is Mr.
Butterworth’s Declaration, but he does not cite any evidence and does not
purport to compare the alleged improved performance of the 5 or greater
ratio to the performance of prior art fastening components. Ex. 2006 ¶ 99.
For example, Mr. Butterworth states that “narrow” fasteners, such as
IPR 2014-01021
Patent 8,747,379 B2

25
fasteners with a length-to-width ratio of 5 or greater, preserve the elasticity
of the side panel, but he does not address whether “narrow” fasteners outside
the recited range existed in the prior art, or whether prior art fasteners could
also preserve side panel elasticity. See id.
Petitioner’s position is more persuasive and better supported by the
record. As Mr. Butterworth testified at his deposition, the ’379 patent does
not ascribe any particular advantage or difference in performance to the 5 or
greater ratio, and indicates ratios outside of the recited ratio (such as 2 or
greater) are also desirable. See Ex. 1014, 153:14–154:17, 156:12–23; Ex.
1001, 17:9–12. Based on Gardner and the full record after trial, a
preponderance of the evidence supports Petitioner’s contention that claims 8
and 22 are obvious in view of the combination of Brandon and Anderson.
14

Claim 9 depends from claim 8. Petitioner provides arguments and
evidence supporting its contention that the limitations of claim 9 are taught
by Brandon, and, thus, the claim would have been obvious in view of the
combination of Brandon and Anderson. See Pet. 32. Patent Owner does not
argue the patentability of claim 9 separately, relying instead on its arguments
for claims 1 and 8, which are addressed above. Based on the full record
after trial and the arguments presented by the parties, a preponderance of the
evidence establishes that claim 9 is unpatentable as obvious in view of the
combination of Brandon and Anderson.
8. Claim 16
Claim 16 depends from claim 1 and further recites, “wherein the
training pant is prefastened to provide a pant-like product for the user.”

14
Petitioner also argues that Long teaches a 7:1 size ratio. Pet. Reply 18.
Trial was not instituted on any ground based on Long for claims 8 or 22.
Inst. Dec. 9. Thus, we do not consider this argument for this Decision.
IPR 2014-01021
Patent 8,747,379 B2

26
Petitioner identifies disclosures in both Brandon and Anderson as teaching
the subject matter of claim 16. See Pet. 33. For example, Petitioner relies
on Anderson’s disclosure that the described training panty “should look like
a normal panty when first put on by the child.” See Ex. 1006, 2:35–36. The
record supports Petitioner’s contentions.
Patent Owner contends that neither Brandon nor Anderson teaches
fastening components disposed on side panels. PO Resp. 45. For the
reasons discussed above for claim 1, we conclude Anderson teaches the
claimed fastening components (and mating fastening components) disposed
on side panels. Patent Owner also argues that neither Brandon nor Anderson
teaches “prefastened” training pants because they do not disclose whether
the described training pants are fastened during manufacture or prior to sale.
This argument is unpersuasive. As discussed above, however, the broadest
reasonable interpretation of this limitation requires that the training pant be
fastened prior to wear, but does not require fastening during manufacture or
prior to sale.
Based on the record and arguments presented, a preponderance of the
evidence supports Petitioner’s contention that claim 16 would have been
obvious in view of Brandon and Anderson.
9. Claims 11 and 14
Petitioner contends claims 11 and 14 are unpatentable in view of the
combination of Brandon, Anderson, and Long. Pet. 42, 44. Both claims
depend from claim 1, and Petitioner relies on the combination of Brandon
and Anderson for the limitations of the independent claim. See id. at 39.
For the “containment flaps” and “surge layer” limitations of claims 11 and
14, respectively, Petitioner relies on elasticized containment flaps 82 and
surge management portion 84 in Long. Id. at 42 (citing Ex. 1007, 4:53–63,
IPR 2014-01021
Patent 8,747,379 B2

27
10:30–50, 11:63–12:16, Figs. 1, 2). Further, Petitioner asserts that a “clear
motivation” existed to combine Long (and Enloe, which is incorporated by
reference) with Brandon and Anderson to avoid soilage, a goal that would be
facilitated by the teachings of Long. Id. (citing Ex. 1007, 10:30–50; Ex.
1012, 2:57–65 (Enloe)).
Patent Owner does not dispute that Long teaches these elements, but
argues instead that Anderson teaches away from the asserted combination
because Anderson teaches that permitting moisture to leak through the outer
cover is advantageous, which would be frustrated by the anti-leak features
taught by Long. See PO Resp. 39–41. This argument is unpersuasive for
same reasons as Patent Owner’s similar argument for claim 1.
Based on the record and evidence presented, Petitioner has shown
sufficiently that the combination of Brandon, Anderson, and Long teaches
the limitations of claims 11 and 14. Petitioner also has articulated reasoning
with rational underpinning to combine these references in the manner
asserted. See KSR, 550 U.S. at 418. Thus, Petitioner has demonstrated by a
preponderance of the evidence that claims 11 and 14 are unpatentable under
§ 103 in view of Brandon, Anderson, and Long.
10. Claims 18 and 24
Claims 18 and 24 each depend from claim 1 and further recite that the
front side panels are “non-stretchable” and “do not comprise elastic
materials,” respectively. Petitioner contends these claims are obvious in
view of Brandon, Anderson, and Long. Pet. 41–42, 44–45. Specifically,
Petitioner relies on Long’s disclosure that side panels 90 may be composed
of “a substantially non-elastomeric material, such as polymer films, woven
fabrics, nonwoven fabrics or the like, as well as combinations thereof.” See
Ex. 1007, 13:18–21. In addition, Petitioner argues that replacing an elastic
IPR 2014-01021
Patent 8,747,379 B2

28
side panel, such as taught in Brandon, with a non-elastomeric panel, such as
taught in Long, would not have been difficult and would have been an
obvious design choice between a finite number of identified, predictable
solutions. Pet. 41–42 (citing KSR, 550 U.S. at 421).
Patent Owner argues that “non-elastomeric” materials are not
necessarily “non-stretchable.” PO Resp. 48–49. As discussed above, the
broadest reasonable interpretation of “non-stretchable” is “unable to
elongate,” and some non-elastomeric materials are able to elongate. Further,
Patent Owner asserts that modifying the elastomeric side panels of Brandon
to incorporate a non-stretchable front side panel would have been difficult,
and would have required “significant modification” of the Brandon training
pants. Id. at 49–50.
As an initial matter, Patent Owner is correct that the teaching of non-
elastomeric side panels in Long does not necessarily teach non-stretchable
side panels because, as Petitioner admitted (Tr. 30:12–31:14), not all non-
elastomeric materials are non-stretchable. We are persuaded, however, that
choosing a non-stretchable material for the side panels would have been an
obvious design choice based on the teachings of the prior art and the
knowledge of skilled artisans at the time of the invention.
Mr. Butterworth testified at his deposition that, at the time of the
invention, a skilled artisan would have known of only three options with
respect to choosing a type of material for the side panels of training pants:
(1) elastic,
15
(2) non-stretchable, and (3) stretchable (but not elastic). See
Ex. 1014, 207:14–208:11. He further testified that a person of ordinary skill
would have been able to choose an appropriate type of material from among

15
As noted earlier, the parties do not dispute that “elastic” and “elastomeric”
are interchangeable for all relevant purposes.
IPR 2014-01021
Patent 8,747,379 B2

29
those options, and would have been able to identify a specific material of
that type. See id. at 254:4–255:15. Although Mr. Butterworth testified in
his Declaration that modifying Brandon’s training pants to incorporate a
non-stretchable front side panel would require “significant modification”
(Ex. 2006 ¶ 112), he did not testify that such modifications would have been
beyond the skill of an ordinary artisan.
The Supreme Court has instructed that:
[w]hen there is a design need or market pressure to solve a
problem and there are a finite number of identified, predictable
solutions, a person of ordinary skill has good reason to pursue
the known options within his or her technical grasp. If this
leads to the anticipated success, it is likely the product not of
innovation but of ordinary skill and common sense. In that
instance the fact that a combination was obvious to try might
show that it was obvious under § 103.
KSR, 550 U.S. at 421. The record supports Petitioner’s contention that a
finite number of identified, predictable solutions for the material
composition of training pant side panels were known to ordinary artisans at
the time of the invention, including non-stretchable materials. Further, the
evidence presented indicates that an ordinary artisan would have been able
to select and implement a non-stretchable material for the front side panels
of a training pant. Thus, a preponderance of the evidence indicates that
claim 18 would have been obvious and, thus, is unpatentable under § 103. A
preponderance of the evidence also indicates that claim 24 is unpatentable as
obvious for similar reasons.
11. Reasonable Expectation of Success
In addition to the arguments addressed above, Patent Owner further
alleged that a person of ordinary skill would not have expected the training
pants taught by the prior art combinations advanced by Petitioner to work
IPR 2014-01021
Patent 8,747,379 B2

30
successfully for its intended purpose. PO Resp. 50–54. Specifically, Patent
Owner contends that a skilled artisan would have expected training pants
with refastenable seams would fail because it would be too easy for children
to disengage the fastening components, causing an unintentional failure of
the seams. See id.
As Petitioner notes (Pet. Reply 22–23), however, the challenged
claims do not require any particular degree of fastening efficacy. Nor does
the ’379 patent identify or discuss the problem posited by Patent Owner,
much less indicate that the claimed invention avoids or mitigates such a
problem, or improves upon the prior art in that respect. Indeed, both the
’379 patent and Anderson utilize hook and loop fasteners, such as Velcro,
which Patent Owner alleges suffers from the problem of unintentional seam
failure. See Ex. 1001, 15:51–59; Ex. 1006, 4:27–32, Figs. 1, 2. Thus,
unintentional seam failure due to the alleged weakness of refastenable seams
is not a persuasive basis on which to distinguish the challenged claims from
the prior art. In other words, a reasonable expectation of success with
respect to the grounds of unpatentability asserted by Petitioner against the
challenged claims here need not include “success” in avoiding the alleged
weakness of refastenable seams, because such a property is not required by
the challenged claims.
Thus, we are not persuaded that the grounds asserted by Petitioner are
defeated because there was no reasonable expectation of success.
12. Secondary Considerations of Non-Obviousness
Patent Owner further contends that secondary considerations of non-
obviousness compel a conclusion that the challenged claims are not
unpatentable as obvious. See Graham v. John Deere Co., 383 U.S. 1, 17–18
(1966) (holding that secondary considerations must be considered to
IPR 2014-01021
Patent 8,747,379 B2

31
determine if challenged claims are not obvious). Specifically, Patent Owner
alleges that the evidence of record establishes commercial success and
industry skepticism, which are strong objective indicia of patentability. PO
Resp. 54–60.
16
Based on the evidence and arguments presented, however,
the evidence of alleged secondary considerations is insufficient to overcome
the strong evidence of obviousness discussed above.
a. Commercial Success
Patent Owner provides extensive evidence of alleged commercial
success, including data regarding sales and relative market share, consumer
studies regarding the specific product features and consumer preferences
driving those sales, and declaration testimony from three witnesses. PO
Resp. 55–60. Based on this evidence, Patent Owner relies on the alleged
commercial success of its PULL-UPS refastenable training pants, and
contends that a nexus exists between that commercial success and the
“patented elastomeric refastenable sides” of the PULL-UPS product. Id.
To establish a nexus between alleged commercial success and the
challenged claims, Patent Owner must show “that the thing (product or
method) that is commercially successful is the invention disclosed and
claimed in the patent.” Demaco Corp. v. F. Von Langsdorff Licensing Ltd.,
851 F.2d 1387, 1392 (Fed. Cir. 1988); see also In re GPAC Inc., 57 F.3d
1573, 1580 (Fed. Cir. 1995) (holding that a nexus was not demonstrated
where “GPAC did not establish which claim(s) of the patent the [allegedly
successful] licensing program incorporates”). Patent Owner does not,

16
As indicated earlier, we need not reach the issue of whether Patent
Owner’s arguments as to secondary considerations are barred due to
collateral estoppel because we conclude that a preponderance of the
evidence establishes that the challenged claims are unpatentable, even
considering Patent Owner’s arguments and evidence.
IPR 2014-01021
Patent 8,747,379 B2

32
however, provide an analysis establishing that its PULL-UPS product
practices any claim or claims of the ’379 patent.
In addition, even assuming arguendo that Patent Owner’s evidence
establishes a nexus between the commercial success of its PULL-UPS
product and the specific refastenable fastening system recited in the
challenged claims, Patent Owner has failed to demonstrate that “the asserted
commercial success of the product [is] due to the merits of the claimed
invention beyond what was readily available in the prior art.” See J. T.
Eaton & Co. v. Atlantic Paste & Glue Co., 106 F.3d 1563, 1571 (Fed. Cir.
1997) (emphasis added). As discussed above, the record establishes that the
refastenable fastening system recited in the challenged claims was taught in
the prior art.
Relying on Gillette Co. v. S.C. Johnson & Son, Inc., Patent Owner
argues that the “fact that all elements of a claim are in the prior art does not
by itself defeat commercial success,” and that “the prior art discloses only
individual elements of the patented training pants, but there is no prior art
that discloses the unique combination found in the claims of the ’379
Patent.” PO Resp. 59 (citing 919 F.2d 720, 725 (Fed.Cir.1990)). In Gillette,
although each individual element of the claimed chemical composition was
known in the art, it was undisputed that the composition as a whole had
“superior properties” that were unique to the composition rather than any
individual component. See 919 F.2d at 725. In contrast, Patent Owner’s
arguments and evidence focus on a single element of its claimed invention—
“refastenable elastomeric sides”—and Patent Owner does not identify any
evidence indicating the claimed refastenable sides (or any other claimed
IPR 2014-01021
Patent 8,747,379 B2

33
feature) had unique properties or advantages beyond those found in the prior
art training pants relied on by Petitioner.
17
See PO Resp. 56–58.
Based on the full record after trial, Patent Owner has not established
an adequate nexus between the alleged commercial success of its PULL-
UPS products and the challenged claims.
b. Industry Skepticism
Patent Owner also posits that the evidence it presents with respect to
reasonable expectation of success also demonstrates industry skepticism of
the efficacy of refastenable elastomeric side panels. See PO Resp. 60.
Skepticism in the art may be relevant and persuasive evidence of non-
obviousness. See Gillette, 919 F.2d at 726. This argument is unpersuasive,
however, for reasons similar to those already discussed above. For example,
Patent Owner has not explained sufficiently how the refastenable seams of
the claimed invention are different, or yield different results, than those of
prior art training pants. Further, Patent Owner has not demonstrated that the
claimed invention actually overcame the alleged concerns underlying the
industry skepticism. Cf. id. (approving the district court’s conclusion that
skepticism was persuasive evidence of non-obviousness where the claimed
invention actually provided better results, contrary to expectations in the
field). Moreover, the challenged claims do not require the refastenable side
panels to be effective to any specific degree with regard to unintentional
seam failures. Thus, skepticism that such side panels could achieve a

17
Indeed, evidence in the record suggests that the only distinction between
the refastenable sides of the challenged claims and Anderson’s refastenable
sides that arguably is identified by Patent Owner—that they are
“elastomeric”—may have been considered a drawback at the time of the
invention. See PO Resp. 51–53 (citing evidence allegedly showing that
refastenable elastomeric side panels were expected to be problematic).

Patent 8,747,379 B2

34
particular degree of efficacy has little relevance to whether the recited
refastenable side panels, or the challenged claims as a whole, are obvious in
light of the prior art.
c. Long-Felt But Unmet Need
In a section titled “Resolving the Level of Ordinary Skill in the Art,”
the Patent Owner’s Corrected Response addresses alleged facts and provides
arguments that appear to advance a theory that the invention of the ’379
patent solved a long-felt but unmet need. See PO Resp. 7–9. While this
aspect of the Response may not meet the standard of clarity required by our
Rules, we consider nonetheless these arguments and conclude they are
unpersuasive for reasons similar to those discussed above with respect to
alleged industry skepticism and reasonable expectation of success. For
example, Patent Owner cites no evidence supporting its allegation that the
training pants of the ’379 patent solved the “problems” it identifies, nor does
Patent Owner explain how any specific feature of the claimed training pants
is distinguishable from the prior art in terms of solving such problems.
13. Conclusion as to Asserted Grounds of Unpatentability
For the reasons discussed above and based on the full record after
trial, we conclude Petitioner has established by a preponderance of the
evidence that: (1) claims 1–10, 12, 13, 15–17, and 19–23 are unpatentable
under § 103 in view of the combination of Brandon and Anderson; and (2)
claims 11, 14, 18, and 24 are unpatentable under § 103 in view of the
combination of Brandon, Anderson, and Long.
C. Petitioner’s Motion to Exclude
Petitioner filed a Motion to Exclude Evidence requesting that several
categories of evidence submitted by Patent Owner be excluded. Paper 38
(“Mot. Excl.”). Patent Owner filed an Opposition to the Motion (Paper 43,
IPR 2014-01021
Patent 8,747,379 B2

35
“Opp. Mot. Excl.”), and Petitioner filed a Reply in support of its Motion
(Paper 46, “Reply Mot. Excl.”).
18

First, Petitioner seeks to exclude all of Patent Owner’s evidence
relating to secondary considerations of non-obviousness as not relevant
under Fed. R. Evid. 401 and 402. Mot. Excl. 2–5. In essence, Petitioner
argues that Patent Owner failed to provide certain analyses and evidence
necessary to sustain its arguments as to secondary considerations and, thus,
all related evidence is irrelevant. See id. Rule 401 states that evidence is
relevant if “(a) it has any tendency to make a fact more or less probable than
it would be without the evidence; and (b) the fact is of consequence in
determining the action.” Petitioner does not dispute that the evidence in
question pertains to facts underlying Patent Owner’s contentions regarding
secondary considerations. Whether Patent Owner failed to provide
sufficient evidence or neglected to supply all of the necessary analysis does
not negate the relevance of that evidence. In addition, we note that
Petitioner’s motion is moot because of our decision above that the
challenged claims are unpatentable even considering this evidence. This
portion of the Motion is denied.
Second, Petitioner moves to exclude essentially all of Patent Owner’s
evidence regarding obviousness as not relevant under Fed. R. Evid. 401 and
402 because, it contends, Patent Owner is collaterally estopped from
advancing the corresponding arguments. Mot. Excl. 6–8. Petitioner’s
motion is moot, however, because of our decision above that the challenged
claims are unpatentable even considering this evidence. This portion of the
Motion is dismissed as moot.

18
Petitioner moved to exclude Exhibit 2042 in the Motion to Exclude, but
withdrew its objection in its Reply. See Reply Mot. Excl. 5.
IPR 2014-01021
Patent 8,747,379 B2

36
Third, Petitioner moves to exclude Exhibits 2032–2036 as not relevant
under Fed. R. Evid. 401 and 402, not authenticated under Fed. R. Evid. 901,
and because they allegedly lack foundation. Mot. Excl. 8–9. Petitioner’s
motion is moot because of our decision above that the challenged claims are
unpatentable even considering this evidence. This portion of the Motion is
dismissed as moot.
Fourth, Petitioner moves to exclude alleged opinions set forth in
paragraph 11 of Exhibit 2039 as not relevant under Fed. R. Evid. 401 and
402. Mot. Excl. 9–11. The testimony at issue addressed considerations
involved in designing training pants prior to the introduction of Patent
Owner’s PULL-UPS products, which Patent Owner relies on for its
commercial success arguments. See Ex. 2039 ¶ 11. This testimony is
clearly relevant to factual issues of consequence in assessing secondary
considerations of non-obviousness. Thus, Petitioner’s motion to exclude
this testimony under Rules 401 and 402 is denied.
19

Finally, Petitioner moves to exclude Exhibits 2017–2021 as
inadmissible hearsay under Fed. R. Evid. 802, and as not authenticated under
Fed. R. Evid. 901. Mot. Excl. 12. The parties do not dispute that these
documents were relied on by Steven S. Bullock—who was proffered by
Patent Owner as an expert witness—in forming the opinions expressed in his
Declaration (Ex. 2024). Mot. Excl. 12; Opp. Mot. Excl. 15. An expert
witness may rely on otherwise inadmissible evidence in forming his
opinions. Fed. R. Evid. 703. Petitioner does not dispute that experts in Mr.

19
Although Petitioner’s arguments for excluding Ms. Panning’s testimony
focus on whether they contain improper opinions because she was not
proffered as an expert, Petitioner does not move to exclude the testimony
under Fed. R. Evid. 701.
IPR 2014-01021
Patent 8,747,379 B2

37
Bullock’s field would reasonably rely on information like Exhibits 2017–
2021 in forming their opinions. See id. Thus, after consideration of the
parties’ arguments, Petitioner’s motion to exclude these exhibits is denied.
D. Motions to Seal
The parties filed several motions to seal. Patent Owner moves to seal
portions of Exhibit 2039, which it asserts contains confidential information
belonging to a non-party, Procter and Gamble. Paper 17, 2. The parties
jointly move to seal portions of Exhibit 1019, the transcript of a deposition
of Cynthia Panning, because it purportedly contains confidential trade secret
information belonging to Patent Owner. Paper 18, 2. Petitioner moves to
seal the portions of its Petitioner’s Reply and Exhibit 1021 (Rebuttal
Declaration of John Blevins) referencing confidential portions of Exhibits
2039 and 1019. Paper 21, 2–3. The parties move jointly to seal Exhibits
2043, 2044, 2046–2049, 2051, and 2052, as well as portions of Patent
Owner’s Motion to Vacate (Paper 25) that reference those exhibits. Paper
29, 1–2. The parties assert that these exhibits contain sensitive and
confidential business, financial, and/or strategy information of Petitioner and
other entities affiliated with Petitioner. Id. at 2–6. Petitioner moves to seal
portions of its Opposition to Patent Owner’s Motion to Vacate as well as
portions of Exhibit 1031, the Declaration of Holly Ellers, which was
submitted in conjunction with its Opposition and purportedly contains
Petitioner’s confidential business information. Paper 32, 2–4. Finally,
Patent Owner moves to seal Exhibit 2055, which purportedly contains the
confidential information of a non-party, Procter and Gamble. Paper 36, 1–2.
The parties also move to enter a proposed Protective Order attached as
Exhibit A to Paper 17.
IPR 2014-01021
Patent 8,747,379 B2

38
Upon review, good cause exists to seal the above information as set
forth in the above motions. In addition, the parties’ proposed Protective
Order is acceptable and will be entered. We note that none of the sealed
information was relied upon or disclosed in this Decision.
Because there is an expectation that information will be made public
where the information is identified in a final written decision, confidential
information that is subject to a protective order ordinarily would become
public 45 days after final judgment in a trial, unless a motion to expunge is
granted. 37 C.F.R. § 42.56; Office Patent Trial Practice Guide, 77 Fed. Reg.
48,756, 48,761 (Aug. 14, 2012). A party who is dissatisfied with this Final
Written Decision, however, may appeal this Decision pursuant to 35 U.S.C.
§ 141(c), and has 63 days after the date of this Decision to file a notice of
appeal. 37 C.F.R. § 90.3(a).
In view of the above, the sealed information discussed above will
remain under seal, at least until the time period for filing a notice of appeal
has expired or, if an appeal is taken, the appeal process has concluded. The
record for the instant proceeding will be preserved in its entirety, and the
confidential documents will not be expunged or made public, pending
possible appeal. Notwithstanding 37 C.F.R. § 42.56 and the Office Patent
Trial Practice Guide, neither a motion to expunge confidential documents
nor a motion to maintain these documents under seal is necessary or
authorized at this time. See 37 C.F.R. § 42.5(b).

CONCLUSION
For the foregoing reasons, Petitioner has shown by a preponderance of
the evidence that claims 1–24 of the ’379 patent are unpatentable under 35
U.S.C. § 103(a).
