I. INTRODUCTION
A. Background
Petroleum Geo-Services (“Petitioner,” or “PGS”) filed a Petition to
institute an inter partes review of claims 1, 2, 18 and 19 of U.S. Patent No.
7,293,520 B2 (“the ’520 patent”).
2
Paper 2 (“PGS Pet.”). WesternGeco
LLC (“Patent Owner”) timely filed a Preliminary Response. Paper 26
(“First Prelim. Resp.”). We instituted trial in Petroleum Geo-Services, Inc.,
v. WesternGeco L.L.C., Case IPR2014-00689, (the “PGS IPR”), for claims
1, 2, 18 and 19 of the ’520 patent on certain grounds of unpatentability
alleged in the Petition. Paper 32 (“Decision to Institute” or “Inst. Dec.”).
Patent Owner, in due course, filed a Response. Paper 43 (“Response”).
Petitioner subsequently filed a Reply. Paper 78 (Reply).
In a separate proceeding, ION Geophysical Corporation and ION
International S.A.R.L., v. WesternGeco L.L.C., Case IPR2015-00565 (PTAB
Jan. 14, 2015) (the “ION IPR”), ION Geophysical Corporation and ION
International S.A.R.L. (“ION”) also filed a Petition to institute an inter
partes review of claims 1, 2, 18, and 19 of the ’520 patent. Paper 3 (“ION
Pet.”). With their Petition, ION also filed a Motion for Joinder, Paper 4
(“Mot.”), seeking to join the ION IPR with the PGS IPR. Mot. 2. Patent
Owner filed an Opposition to ION’s Motion for Joinder. Paper 10 (“Opp.,”).
We instituted trial in the ION IPR and granted ION’s Motion for Joinder.

Paper 14 (“ION Decision to Institute” or “ION Inst. Dec.”). We ordered
ION not to file papers, engage in discovery, or participate in any deposition
or oral hearing in IPR2014-00689 without obtaining authorization. ION
was, however, permitted to appear in IPR2014-00689 so that it could receive
notification of filings and attend depositions and the oral hearing. Patent
Owner subsequently filed a Preliminary Response to ION’s Petition. Paper
70 (“ION Prelim. Resp.”).
In addition, Petitioner filed a Motion to Exclude. Paper 85. Patent
Owner filed an Opposition to Petitioner’s Motion to Exclude (Paper 90),
and Petitioner filed a Reply. Paper 94. Also, Petitioner filed three Motions
to Seal (Papers 81, 87, and 97), and Patent Owner filed a Motion to Seal.
Paper 91.
An oral hearing was held on July 30, 2015. A transcript of the hearing
is included in the record. Paper 100 (“Tr.”).
The Board has jurisdiction under 35 U.S.C. § 6(c). This Final Written
Decision is entered pursuant to 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73.
For the reasons that follow, we determine that Petitioner has proven, by a
preponderance of the evidence, that claims 1, 2, 18 and 19 of the ’520 patent
are unpatentable.
B. Additional Proceedings

C. The ’520 Patent
The ’520 patent (Ex. 1001), titled “Control System for Positioning of
a Marine Seismic Streamers,” generally relates to a method and apparatus
for improving marine seismic survey techniques to more effectively control
the movement and positioning of marine seismic streamers towed in an array
behind a boat. Ex. 1001, 1:24–36. As illustrated in Figure 1 of the ’520
patent reproduced below, labeled Prior Art, a seismic source, for example,
air gun 14, is towed by boat 10 producing acoustic signals, which are
reflected off the earth below. Id. The reflected signals are received by
hydrophones (no reference number) attached to streamers 12, and the signals
“digitized and processed to build up a representation of the subsurface
geology.” Id. at 36–41.
IPR2014-00689
Patent 7, 293,520 B2
5

Figure 1, above, depicts an array of seismic streamers 12 towed
behind boat 10.
In order to obtain accurate survey data, it is necessary to control the
positioning of the streamers, both vertically in the water column, as well as
horizontally against ocean currents and forces which can cause the normally
linear streamers to bend and undulate and, in some cases, become entangled
with one another. Id. at 1:42–2:16. As illustrated in Figure 1, above, each
streamer is maintained in a generally linear arrangement behind the boat by
deflector 16 which horizontally positions the end of each streamer nearest
the boat. Id. at 3:36–45. Drag buoy 20 at the end of each streamer farthest
IPR2014-00689
Patent 7, 293,520 B2
6
from the vessel creates tension along the streamer to maintain the linear
arrangement.
To control the position and linear shapes of the streamers, a plurality
of streamer positioning devices, called “birds” 18 or “SPD’s” (streamer
positioning devices), are attached along the length of each streamer. Id. at
3:53–55. The birds are horizontally and vertically steerable and control the
shape and position of the streamer in both vertical (depth) and horizontal
directions. Id. at 3:55–61. The birds’s job is usually to maintain the
streamers in their linear and parallel arrangement, because when the
streamers are horizontally out of position, the efficiency of the seismic data
collection is compromised. Id. at 2:4–12. The most important task of the
birds, the specification explains, is to keep the streamers from tangling. Id.
at 4:4–5.
To control the birds, and hence the array of streamers, the ’520 patent
describes a distributed control system using global control system 22 located
on the vessel, and a local control system at each bird to maintain the
streamers in their particular linear and parallel arrangement. Id.
at 3:62–66. In an embodiment of the described control system, global
control system 22 monitors the actual positions of the birds on the streamers
and “and is programmed with the desired positions of or the desired
minimum separations between the seismic streamers 12.” Id. at 4:21–25.
Global control system 22 uses the desired and actual positions of the birds to
“regularly calculate updated desired vertical and horizontal forces the birds
should impart on the seismic streamers 12 to move them from their actual
positions to their desired positions.” Id. at 4:37–40. Global control system
22 then communicates this information to the birds’s local control system.
Id. at 5:6–10.
IPR2014-00689
Patent 7, 293,520 B2
7
The ’520 patent explains that the “inventive control system” has two
primary modes, a feather angle mode, and a turn control mode. Id. at 10:27–
29. The feather angle mode is used to maintain the linear form of the
streamer at an angle offset from the direction of towing, usually to account
for ocean crosscurrents affecting the streamers. Id. at 10:29–37. The ’520
patent explains that in the feather angle mode
[t]he feather angle could be input either manually, through use
of a current meter, or through use of an estimated value based
on the average horizontal bird forces. Only when the
crosscurrent velocity is very small will the feather angle be set
to zero and the desired streamer positions be in precise
alignment with the towing direction.
Id. at 10:32–36.
The turn control mode is used when the vessel is turning during a
survey operation. Id. at 10:38–40. In a first part of the turn, birds 18 are
instructed to “throw out” the streamer by generating a force in the opposite
direction from the turn. Id. at 10:40–44. In a second part of the turn, the
birds are directed back to the position defined by the feather angle mode. Id.
The control system determines the first and second part of the turn according
to data provided by the vessel navigation system. Id. at 10:50–53.
The control system can also operate in a streamer separation mode,
important for example during inclement weather conditions to keep the
streamers from tangling. Id. at 10:54–57. In this mode, the birds receive
either desired horizontal force, or horizontal position information to
maintain the streamers a desired horizontal distance spaced apart from one
another, and, the streamers can also be separated in depth. The specification
explains that “[i]n this control mode, the global control system 22 attempts
to maximize the distance between adjacent streamers. The streamers 12 will
IPR2014-00689
Patent 7, 293,520 B2
8
typically be separated in depth and the outermost streamers will be
positioned as far away from each other as possible.” Id. at 10:57–65.
According to the ’520 patent, these different modes allow the vessel to
operate more efficiently, turn faster and lower the incidents of tangling
during survey operations leading to a reduction in time and equipment costs
of marine surveying. Id. at 10:44–46, 2:23–25.
D. Illustrative Claim
Claims 1 and 18 are independent. Claim 1, a method claim and claim
18 an apparatus claim, illustrate the claimed subject matter:

1. A method comprising:
(a) towing an array of streamers each having a plurality of
streamer positioning devices there along contributing
to steering the streamers;
(b) controlling the streamer positioning devices with a
control system configured to operate in one or more
control modes selected from a feather angle mode, a
turn control mode, and a streamer separation mode.

Ex. 1001, 11:10–18 (emphasis added).

18. An apparatus comprising:
(a) an array of streamers each having a plurality of
streamer positioning devices there along;
(b) a control system configured to use a control mode
selected from a feather angle mode, a turn control
mode, a streamer separation mode, and two or more of
these modes.

Id. at 12:4–10. (emphasis added).

II. CLAIM CONSTRUCTION
A. Legal Standard
In an inter partes review, claim terms in an unexpired patent are
interpreted according to their broadest reasonable construction in light of the
specification of the patent in which they appear. 37 C.F.R. § 42.100(b); see
also In re Cuozzo Speed Techs., LLC., 778 F.3d 1271, 1278–82 (Fed. Cir.
2015) (“Congress implicitly approved the broadest reasonable interpretation
standard in enacting the AIA,” and “the standard was properly adopted by
PTO regulation.”). Claim terms are given their ordinary and customary
meaning as would be understood by a person of ordinary skill in the art at
the time of the invention and in the context of the entire patent disclosure.

specification “reveal[s] a special definition given to a claim term by the
patentee that differs from the meaning it would otherwise possess[,] . . . the
inventor’s lexicography governs.” Phillips v. AWH Corp., 415 F.3d 1303,
1316 (Fed. Cir. 2005) (en banc) (citing CCS Fitness, Inc. v. Brunswick
Corp., 288 F.3d 1359, 1366 (Fed. Cir. 2002)).
If an inventor acts as his or her own lexicographer, the definition must
be set forth in the specification with reasonable clarity, deliberateness, and
precision. Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243,
1249 (Fed. Cir. 1998). If a feature is not necessary to give meaning to what
the inventor means by a claim term, it would be “extraneous” and should not
be read into the claim. Renishaw PLC, 158 F.3d at 1249; E.I. du Pont de
Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir.
1988). Only terms which are in controversy need to be construed, and then
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).
We apply these general rules in construing the claims of the ’520
patent.
In our Decision to Institute we determined that an “array of streamers”
as “more than one streamer.” Inst. Dec. 11. We also determined that
“feather angle mode,” means “a control mode that attempts to keep each
streamer in a straight line offset from the towing direction by a certain
feather angle.” Id. at 12. We further determined that “turn control mode” is
“a control mode, in which during a turn, the streamer positioning devices
generate force in the opposite direction of the turn and then are directed back
into position.” Id. at 13. We interpreted “streamer separation mode” as “a
mode to control separation, or spacing, between streamers.” Id. at 15. In
addition, we determined for apparatus claim 18, that the limitations recited
IPR2014-00689
Patent 7, 293,520 B2
11
in paragraph b) constituted a Markush group, and therefore “the prior art
discloses the limitation if one alternative, i.e. a feather angle, a turn control
mode, or a streamer mode, is in the prior art.” Id. (citing Fresenius USA,
Inc. v. Baxter Int’l, Inc., 582 F.3d 1288, 1298 (Fed. Cir. 2009)).
Based on the full record developed during trial, we adopt those
constructions not discussed below for purposes of this Decision. Because
Patent Owner disagrees with our interpretations of “feather angle mode” and
“streamer separation mode” as recited in both claims 1 and 18, we provide
below additional analysis and the correct claim construction for both these
claim limitations. See PO Resp. 7–10. Additionally, Petitioner contends
that the term “control mode” should be construed. Reply 4–5.
B. Feather Angle Mode
We determined in the Decision to Institute that “feather angle mode”
means “a control mode that attempts to keep each streamer in a straight line
offset from the towing direction by a certain feather angle.” Inst. Dec. 12.
The parties, however, disagree over the meaning of the phrase “by a certain
feather angle,” set forth in our construction. Petitioner insists that it means
“no feather angle is input or set.” Reply 8–9. Patent Owner disagrees and
asserts that the feather angle is “a specific selection/input (whether manually
or through other means) of the angle into the global control system.” PO
Resp. 7–8. This point requires clarification. There is only a very brief
description of “feather angle mode” in the specification, which, in its
entirety states:
In the feather angle control mode, the global control system 22
attempts to keep each streamer in a straight line offset from the
towing direction by a certain feather angle. The feather angle
could be input either manually, through use of a current meter,
or through use of an estimated value based on the average
IPR2014-00689
Patent 7, 293,520 B2
12
horizontal bird forces. Only when the crosscurrent velocity is
very small will the feather angle be set to zero and the desired
streamer positions be in precise alignment with the towing
direction.
Ex. 1001, 10:29–37. Although this passage indicates that there may be
various ways, e.g. estimation, manual input, current measurement, to input
or determine the feather angle, it is clear that the “feather angle” itself exists
as a value used by global control system 22 to control the streamers
positions.
Petitioner argues that the above description “discloses implementing
feather angle mode through use of a current meter” that “steers the streamers
to counteract the current and attempts to keep them straight and parallel
without a feather angle being input.” Reply 8–9. Petitioner misconstrues
the written description. The object of the second sentence isn’t “feather
angle mode,” it is “feather angle.” The specification states explicitly “[t]he
feather angle could be input either manually, through use of a current meter,
or through use of an estimated value based on the average horizontal bird
forces.” This sentence does not read as alternatives to the feather angle
itself, but different ways to determine a feather angle value.
Patent Owner’s explanation is the more reasonable one here.
Accordingly, we clarify our claim construction so that it is understood that
the feather angle mode includes global control system 22 using a certain
feather angle value to control the birds and streamers. The “feather angle
mode” is properly, “a control mode that attempts to keep each streamer in a
straight line offset from the towing direction using a certain feather angle.”
C. Streamer Separation Mode
Patent Owner contends that our construction of “streamer separation
mode,” as “a mode to control separation, or spacing, between streamers,” is
IPR2014-00689
Patent 7, 293,520 B2
13
incomplete. PO Resp. 9, 13. Patent Owner argues that this interpretation
“fails to define what it means to “control separation.” Id. Patent Owner’s
position is that streamer separation mode is “precisely controlling, and
therefore, maintaining” streamer separation. Id. at 20. However, the word
“precisely” is superfluous without some stated relative quantity for
comparison. That a behavior-predictive model as disclosed in the
specification might make the control more accurate or “precise” does not
persuade us that our original interpretation of this term is incorrect. See id.
As we wrote in our original construction, we are not apprised of any
evidence in the specification or claims that any specific distance between the
streamers in the separation mode is “set and maintain[ed]” as Patent Owner
urges. Inst. Dec. 14. The phrase “set and maintain” may be an explanation
of how a system could “control separation” but this phrase is not found
anywhere in the specification or claims. Indeed, the ’520 patent sets forth
various ways that separation or spacing can be controlled between streamers,
[i]n the preferred embodiment of the present invention, the global control
system 22 monitors the actual positions of each of the birds 18 and is
programmed with the desired positions of or the desired minimum
separations between the seismic streamers 12.” Ex. 1001 at 4:21–25
(emphasis added). Patent Owner has not provided persuasive evidence
adequate to explain why the proper claim construction requires that the
phrase “to control separation” be further defined more precisely as, “to set
and maintain,” the spacing.
We determine based on the specification, claim language, and
evidence from the complete record before us, that our initial claim
construction is correct, and that under the broadest reasonable interpretation,
IPR2014-00689
Patent 7, 293,520 B2
14
“streamer separation mode,” means “a mode to control separation, or
spacing, between streamers.”
D. Control Mode
Petitioner contends that Patent Owner has asserted, covertly, a claim
construction for the term “control mode.” Reply 4–5. Patent Owner argues
that Workman does not disclose any modes and that “as used in the ’520
patent, a ‘control mode’ refers to a goal-oriented automated configuration.”
PO Resp. 19–20 (citing Ex. 2042 ¶¶190–191). Petitioner argues that such an
interpretation, to the extent it is a claim construction proffered by Patent
Owner, is too narrow and that “a control mode is simply a particular way of
operating a device.” Reply 4.
The specification of the ’520 patent does not provide a definition of
this term. The specification states generally “[t]he inventive control system
will primarily operate in two different control modes: a feather angle control
mode and a turn control mode.” Ex. 1001, 10:27–29. Patent Owner’s
Declarant, Dr. Triantafyllou testifies that Workman does not disclose “model
based control” because “there is no goal-oriented steering disclosed at all.”
Ex. 2042 ¶ 190. Dr. Triantafyllou states that
[i]n contrast, the ’520 patent describes goal-oriented automated
configurations maintained by “control modes”: feather angle
mode automatically steers to achieve a particular feather angle,
turn control mode automatically steers to turn faster, and
streamer separation mode automatically steers to achieve and
maintain desired separations.
Id. at ¶ 191 (citing Ex. 1001, 10:27–65). Dr. Triantafyllou’s testimony is
essentially that, for example in streamer separation mode, there is defined (a)
a goal, “to achieve and maintain desired separations” and, (b) automation,
e.g. “automatically steer[ing] to achieve and maintain desired separations.”
IPR2014-00689
Patent 7, 293,520 B2
15
Id. This testimony, however, merely describes a desired result, i.e. “to
maintain desired separations,” and how such a goal could be accomplished,
by “automatically steering.” It is axiomatic that any operation of a computer
system or program has a goal or desired result, otherwise its operation, even
its existence, would be pointless. See MICROSOFT
®
PCDICTIONARY 118 (5
th

Ed. 2002) (“computer n. Any device capable of processing information to
produce a desired result.”). Moreover, the word “automatically” introduces
more ambiguity into the claim interpretation because it is not clear from the
specification or Dr. Triantafyllou’s testimony what “automatically” means,
or that manual input or operations associated with the systems steering
operations are excluded. See Ex. 1001, 10:32–33 (“The feather angle could
be input [] manually.”). We, therefore, decline to adopt Patent Owner’s
purported construction of this term.
A common computer term, Microsoft’s PC Dictionary defines the
word as “mode n. The operational state of a computer or a program.”
MICROSOFT
®
PCDICTIONARY 344 (5
th
Ed. 2002). Under this definition, a
“mode” controls the state, i.e., operation, or even lack of operation, of a
computer or computer program as is most consistent with the written
description and context of the ’520 patent. Because at least Patent Owner’s
first argument with respect to anticipation focuses on this term, we
determine that “control mode” means “operational state.”
III. ANALYSIS
A. Claims 1 and 18 – Anticipation by Workman
To prevail on its patentability challenge, Petitioner must establish
facts supporting its challenge by a preponderance of the evidence. 35 U.S.C.
§ 316(e); 37 C.F.R. § 42.1(d). Petitioner asserts that claims 1 and 18 are
anticipated by Workman under 35 U.S.C. § 102. Pet. 28–32; Reply 11–14.
IPR2014-00689
Patent 7, 293,520 B2
16
Patent Owner disagrees, contending that Workman fails to disclose actively
controlling its streamers in control modes as recited in the independent
claims. PO Resp. 19–20.
“A claim is anticipated only if each and every element as set forth in
the claim is found, either expressly or inherently described, in a single prior
art reference.” Verdegaal Bros. Inc. v. Union Oil Co., 814 F.2d 628, 631
(Fed. Cir. 1987). “The identical invention must be shown in as complete
detail as is contained in the . . . claim.” Richardson v. Suzuki Motor Co., 868
F.2d 1226, 1236 (Fed. Cir. 1989). The elements must be arranged as
required by the claim, but this is not an ipsissimis verbis test, i.e., identity of
terminology is not required. In re Bond, 910 F.2d 831, 832 (Fed. Cir. 1990).
“[U]nless a reference discloses within the four corners of the
document not only all of the limitations claimed but also all of
the limitations arranged or combined in the same way as recited
in the claim, it cannot be said to prove prior invention of the
thing claimed and, thus, cannot anticipate under 35 U.S.C. §
102.”
Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008).
Whether a patent is invalid as anticipated is a two-step inquiry. See
Power Mosfet Tech., LLC. v. Siemens AG, 378 F.3d 1396, 1406 (Fed. Cir.
2004). The first step requires construction of the claims. Id. The second
step in the analysis requires a comparison of the properly construed claim to
the prior art. Id.
1. Overview of Workman
Workman discloses a method for controlling the position and shape of
marine seismic streamer cables towed by a vessel. Ex. 1004, Abstract, Fig.
1. More specifically, Workman teaches that real time signals, i.e. actual
signals, from a towed streamer array are compared to corresponding input
IPR2014-00689
Patent 7, 293,520 B2
17
threshold parameters, to determine if the cables should be repositioned. Id.
at col. 2, ll. 47–51. Workman discloses that the positions of seismic
streamer cables are controlled by a plurality of birds and tail buoys “for
adjusting the vertical and lateral positions of the streamer cables 13.” Id. at
col. 3, ll. 16–19. Figure 2 of Workman is reproduced below.

Figure 2 of Workman illustrates diagrammatically, seismic data
acquisition system 5 for positioning streamer cables 13 including streamer
controller 16 receiving instructions from streamer control processor 40. Id.
at col. 4, ll. 16–18. Within data acquisition system 5, Workman also
discloses network solution system 10 which uses a “Kalman filter solution
on the signals it receives from the vessel positioning system 20 and location
sensing devices 15.” Id. at col. 3, ll. 47–49. Workman states that once the
real time position signals are obtained, “[t]he streamer control processor 40
IPR2014-00689
Patent 7, 293,520 B2
18
evaluates these real time signals and the threshold parameters from the
terminal 32 to determine when the streamer cables 13 need to be
repositioned and to calculate the position correction required to keep the
streamer cables 13 within the threshold parameters.” Id. at col. 4, ll. 12–17.
Threshold values can be, for example, minimum streamer cable separations,
minimum allowable seismic coverage, maximum hydrophone noise
levels,and minimum obstructive hazard separation. Id. at col. 3, l. 66–col. 4,
l. 3. Besides repositioning of the streamer cables according to the
comparison of real time signals and threshold parameters, Workman
discusses an “at risk” situation such as entanglement of the streamer cables,
or obstructive hazards. Id. at col. 4, ll. 45–51. In an “at risk” situation,
certain parameters may be disregarded, for example, the hydrophone noise
level parameter. Id. at col. 4, ll. 41–46. In other situations, the streamer
cables may be repositioned due specifically to the level of hydrophone noise.
Id. at col. 5, ll. 15–19.

2. Claims 1 and 186
Patent Owner argues that Workman does not anticipate claims 1 and
18 for essentially three reasons, (a) Workman does not actively control its
streamers in control modes; (b) “Workman does not disclose any modes;”
and (c) Workman does not disclose a “streamer separation mode.” PO Resp.
19–20.
Enablement
Petitioner addresses an enablement issue that, at least in this
proceeding, is not clearly and specifically raised by Patent Owner.
7
See
Reply 14–19, PO Resp. 32. Patent Owner states that “[t]here is no support
for Dr. Evans’s assertion unless one presupposes that Workman has a
working lateral steering system, which it does not . . . [b]ecause Workman
explicitly discourages active and continuous positioning of streamers.” PO
Resp. 32. (citing Ex. 2042 ¶¶ 98, 105, 199–200). To the extent it has been
raised here, we address enablement because it is a threshold issue with
respect to anticipation. A patent claim “cannot be anticipated by a prior art
reference if the allegedly anticipatory [disclosure] cited as prior art [is] not
enabled.” In re NTP, Inc., 654 F.3d 1279, 1301 (Fed. Cir. 2011). Although
anticipation is a question of fact, whether a prior art reference is enabling is
a question of law with underlying factual inquiries. Id.
The standard for what constitutes proper enablement of a prior art

6
Claims 1 and 18 recite substantively the same limitations of “control
mode” and “streamer separation mode.” Although claim 1 is a method
claim, and claim 18 is an apparatus claim we understand no substantive
difference between these claim terms and our analysis and construction
applies equally to both.

The issue of enablement of the prior art is specifically raised by Patent
Owner in IPR2014-00688.

reference for purposes of anticipation under section 102 differs from the
enablement standard for a patent application under section 112. See Verizon
Services Corp., v. Cox Fibernet Virginia, Inc., 602 F.3d 1325, 1337 (Fed.
Cir. 2010). Anticipation does not require the actual creation or reduction to
practice of the prior art subject matter; anticipation requires only an enabling
disclosure. See Schering Corp., v. Geneva Pharma, Inc., 339 F.3d 1373,
1380 (Fed. Cir. 2003); citing In re Donohue, 766 F.2d 531, 533 (Fed. Cir.
1985).
There is no dispute that streamer positioning devices which could be
laterally, or horizontally, steered were known in the prior art before the
priority date of the ’520 patent. The ’520 patent itself describes “[a]nother
system for controlling a horizontally steerable bird is disclosed in our
published PCT International Application No. WO 98/28636.” Ex. 1001,
2:38–40. Further, discussing Figure 1 labeled “Prior Art” the ’520 patent
explains that “located between the deflector 16 and the tail buoy 20 are a
plurality of streamer positioning devices known as birds 18. Preferably the
birds 18 are both vertically and horizontally steerable.” Id. at 3:53–56. See
Bristol-Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1379
(Fed. Cir. 2001). “It is well settled that “enablement of an anticipatory
reference may be demonstrated by a later reference.”)
Workman refers also in the Background of the Invention to known
SPD’s which control lateral position of streamers, “streamer positioning
devices are well known in the art . . . For example, devices to control the
lateral positioning of streamer cables by using camber-adjustable hydrofoils
or angled wings are disclosed in U.S. Pat. Nos. 4,033,278 and 5,443,027.”
Ex. 1004, 1:45–58. Moreover, it is presumed that Workman is enabled. See
Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F. 3d 1313, 1355 (Fed. Cir.
IPR2014-00689
Patent 7, 293,520 B2
21
2003) (“an accused infringer should be [] entitled to have the district court
presume the enablement of unclaimed (and claimed) material in a prior art
patent defendant asserts against a plaintiff.”).
We are persuaded on the record before us that at least Workman and
PCT International Application No. WO 98/28636 (“’636 PCT”) sufficiently
describe lateral steering such that one of ordinary skill in the art would be
able to practice lateral steering of SPD’s. Further, we note that neither
claims 1 or 18 recite specifically a limitation that the streamer positioning
devices are laterally steered. In fact, Patent Owner does not attempt to
distinguish its invention over Workman on the basis of “lateral steering,”
only that Workman’s streamers are not “actively managed.” PO Resp. 32.
Patent Owner’s arguments with respect to the prior art disclosure, or lack
thereof, of lateral steering, active control, and ostensibly non-enablement of
Workman are vague and unpersuasive.
For enablement there are two distinct burdens of proof, Petitioner’s
burden of persuasion, which never shifts, and the burden of production that
shifted in this case to Patent Owner. Dynamic Drinkware, LLC v. National
Graphics, Inc., No. 2015-1214, 2015 WL 5166366, t *4 (Fed.Cir. Sept. 4,
2015) (“[t]he burden of production then shifted to National Graphics [Patent
Owner] to argue or produce evidence . . . that Raymond is not prior art”).
We determine that Patent Owner has not met its burden of production, i.e.
sufficient arguments or evidence which overcome the presumption that
Workman is enabled as to lateral steering and active control of SPD’s.
Control Mode
Patent Owner’s arguments with respect to anticipation each turn
around an erroneous claim construction of “control mode.” Patent Owner
argues that different from the claimed control modes which actively control
IPR2014-00689
Patent 7, 293,520 B2
22
the streamers, “Workman is concerned with noise minimization rather than
generating noise through actively controlling streamer positioning devices.”
PO Resp. 19. The correct interpretation of “control mode” does not include
any aspect, state or condition that requires “active control.” We construed
“control mode” to mean “operational state.” Whether Workman’s network
solution system 10 or streamer control processor 40 does, or does not
disclose “active control” in any of its operations is irrelevant because we are
not persuaded that “control mode” in either claim 1 or 18 includes “active
control.”
Turning to Patent Owner’s next argument that “control mode” is “a
goal-oriented automated configuration,” not disclosed by Workman, this
argument is similarly unpersuasive. PO Resp. 19–20. As discussed above,
the appropriate claim construction of “control mode” is “operational state.”
Workman clearly discloses a computerized streamer control system having
an operational state, being “a network solution system 10 for determining
the position of the streamer cables 13 and seismic sources 12, and a streamer
cable controller 16 for controlling the streamer positioning devices.” Ex.
1004, 3:40–43. To the extent that Patent Owner’s explanation of a control
mode having “a goal-oriented automated configuration” is even relevant to
the comparison with Workman we are still not apprised of a substantive
difference between the claims and the prior art. Workman discloses that
“the network solution system 10 implements a Kalman filter solution on the
signals it receives . . . output[ing] real time streamer cable shapes, streamer
cable positions, and streamer cable separations.” Id. at 3:46–51. A Kalman
filter is explicitly part of the automated computer network solution system
10 performing data acquisition and determination of various output values,
directed to the goal of controlling the streamers and their separations from
IPR2014-00689
Patent 7, 293,520 B2
23
one another. Workman therefore discloses an operational state of a
computer system that, as specifically stated by Workman, determines
streamer shapes, positions, and separations.
Streamer Separation Mode
As discussed above, we are not persuaded that streamer separation
mode is properly defined as having a streamer spacing “set and
maintain[ed]” as Patent Owner promotes. The appropriate claim
construction of “streamer separation mode” is “a mode to control separation,
or spacing, between streamers.” Patent Owner contends that under the
proper definition the threshold spacing parameters disclosed by Workman
“fails to control any separation or spacing (or set and maintain separation
or spacing, for that matter).” PO Resp. 22 (citing Ex. 2042 ¶¶ 193–194.)
Patent Owner’s own arguments, however, contradict this position. Patent
Owner states that “Workman’s system is purely reactionary; it lies in wait
and attempts to reposition the streamers only in the event that a certain
threshold value is violated.” Id. This argument asserts, in effect, the
operational state occurring under certain conditions, e.g. violation of a
spacing threshold, the streamer is “repositioned” to control separation or
spacing between streamers as the proper construction elucidates. Indeed Dr.
Triantafyllou’s testimony supports our understanding where he states that
“Workman does not move the streamers unless it violates a minimum
threshold.” Ex. 2042 ¶ 194. Moreover, the fact that an additional parameter
such as a high noise level might restrain the system from repositioning the
streamers even if the threshold is exceeded makes no difference in our
understanding that under appropriate operating conditions Workman
controls streamer separation. PO Resp. 23.
IPR2014-00689
Patent 7, 293,520 B2
24
Patent Owner argues further that “[t]here is also no teaching in
Workman of how much to correct, or where the streamers will end up once
the violation is remedied.” Id. This is not persuasive because neither claim
1 nor claim 18, nor the proper construction of “streamer separation mode”
includes any definition or limitation relating to a magnitude of correction or
control.
In addition to disclosing an array of streamers and streamer
positioning devices, the evidence shows that Workman expressly teaches an
operational state of a streamer control system that is no different than the
claimed “control system configured to use a control mode selected from . . .
a streamer separation mode” as recited in 18, or as called for in claim 1,
“controlling the streamer positioning devices with a control system
configured to operate in one or more control modes selected from . . . a
streamer separation mode.”
We are persuaded by the complete record before us that Petitioner has
shown by a preponderance of the evidence that each of the limitations of
independent claims 1 and 18 are disclosed by Workman.
B. Claims 1, 2, 18 and 19 – Obviousness over Workman
1. Claims 1 and 18
Patent Owner contends that our Decision to Institute did not provide
legally sufficient obviousness analysis and “fails to apprise Patent Owner of
the specific obviousness arguments going to trial.” PO Resp. 23–24 (citing
In re Zurko, 258 F.3d 1379, 1386 (Fed. Cir. 2001); In re Vaidyanathan, 381
Fed. App’x. 985, 994 (Fed. Cir. 2010); Perfect Web Techs., Inc. v. InfoUSA,
Inc., 587 F.3d 1324, 1330 (Fed. Cir. 2009)). Specifically, Patent Owner
argues that “[t]he obviousness case is now a moving target, with Patent
Owner left guessing as to what features the Board considers missing from
IPR2014-00689
Patent 7, 293,520 B2
25
Workman, but that would be obvious in view of the level of ordinary skill in
the art.” Id. at 24.
It is well settled that novelty under 35 U.S.C. § 102 and
nonobviousness under 35 U.S.C. § 103 are separate conditions of
patentability. See Cohesive Tech., Inc. v. Waters Corp., 543 F.3d 1351,
1363 (Fed. Cir. 2008). “[I]t does not follow that every technically
anticipated invention would also have been obvious.” In re Fracalossi, 681
F.2d 792, 796 (CCPA 1982) (Miller, J., concurring).
The tests for anticipation and obviousness are different. Cohesive,
543 F.3d at 1364. Obviousness generally requires an analysis under the
Graham factors. Id. In the instant case, however, we agree with Petitioner
that Workman, as a standalone reference discloses all of the limitations of
claims 1 and 18 including “control mode” and “streamer separation mode”
as construed and discussed above. In other words, there is no element of
claims 1 and 18 missing from Workman as discussed above in relation to
anticipation that necessitates modification, additional rationale, or articulated
reasoning. Inasmuch as Workman is relied upon as the sole reference for
both anticipation and obviousness grounds and is directed to the same field
of endeavor seeking to solve the same, or similar problem of controlling
birds, i.e. SPD’s, and streamers in a towed seismic survey array as in the
’520 patent, this case is particularly appropriate for application of the maxim
that anticipation is the epitome of obviousness. Fracalossi, 681 F.2d at 794.
All that remains for this ground is to address secondary considerations,
which we do below.
2. Claims 2 and 19
Petitioner asserts that dependent claims 2 and 19 would have been
obvious over Workman. A patent is invalid for obviousness:
IPR2014-00689
Patent 7, 293,520 B2
26
if the differences between the subject matter sought to be
patented 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 pertains.
35 U.S.C. § 103. Obviousness is a question of law based on underlying
factual findings: (1) the scope and content of the prior art; (2) the differences
between the claims and the prior art; (3) the level of ordinary skill in the art;
and (4) objective indicia of nonobviousness. See Graham v. John Deere Co.
of Kansas City, 383 U.S. 1, 17–18 (1966). Courts must consider all four
Graham factors prior to reaching a conclusion regarding obviousness. See
Eurand, Inc. v. Mylan Pharms., Inc. (In re Cyclobenzaprine Hydrochloride
Extended-Release Capsule Patent Litig.), 676 F.3d 1063, 1076–77 (Fed. Cir.
2012). As the party challenging the patentability of the claims at issue,
Petitioner bears the burden of proving obviousness by a preponderance of
the evidence. See 35 U.S.C. § 316(e).
Both claims 2 and 19 depend from respective independent claims 1
and 18, and relate specifically to the feather angle mode. For example,
claim 19 recites
19. The apparatus of claim 18 wherein the control mode is the
feather angle mode, and the controlling comprises the control
system attempting to keep each streamer in a straight line offset
from a towing direction by a feather angle.
As discussed above in our claim construction, “feather angle mode” is, “a
control mode that attempts to keep each streamer in a straight line offset
from the towing direction using a certain feather angle.” We identified the
scope of Workman above, which does not describe a feather angle, and
Petitioner concedes that Workman does not disclose a feather angle, or using
a feather angle value to control the streamer array. Pet. 32.
IPR2014-00689
Patent 7, 293,520 B2
27
Despite this, Petitioner alleges that a person of ordinary skill in the art
“would have had reason to implement a ‘feather angle mode,’ given the
teachings of Workman and common understandings in the art, with an
expectation of success.” Id. at 33 (citing Ex. 1002 ¶ 143). Patent Owner
disagrees, and contends that Dr. Evans makes unsupported suppositions as to
the prior art teachings, draws erroneous conclusions of fact and fails to
explain sufficiently why one of skill in the art would have been motivated to
use a feather angle in a streamer array control system. PO Resp. 28–30.
With respect to the appropriate level of skill in the art, Petitioner’s
Declarant, Dr. Evans states that a person of ordinary skill in the art of marine
seismic surveying should have for example a Master’s degree or Ph.D. in
ocean engineering, mechanical engineering, geophysics, or a related area, an
understanding of hydrodynamics and advanced control systems, and at least
three years of experience designing and operating marine seismic surveys,
including significant field experience aboard marine vessels undertaking
marine seismic surveys. Ex. 1002 ¶ 23. According to Dr. Triantafyllou,
Patent Owner’s expert, one of ordinary skill in the art would have a
“Bachelor of Science in ocean engineering or control systems; or five years
of experience in the field of ocean engineering or marine seismic surveys.”
Ex. 2042 ¶ 18.
There is no specific dispute regarding the level of ordinary skill in the
art between the parties although Petitioner’s definition essentially involves
greater educational component and specific field experience on a survey
vessel. Notwithstanding the evidence on skill level presented by the parties,
the level of skill in the art often can be determined from a review of the prior
art. See Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158,
163–64 (Fed. Cir. 1985). Based on our review of the prior art and the parties
IPR2014-00689
Patent 7, 293,520 B2
28
definitions, the applicable field of endeavor is marine seismic surveying, and
the person of ordinary skill in the art would have at least a bachelor’s degree
in ocean, mechanical, geophysical or electrical engineering, or a similar
science degree, and a minimum of 3 years of marine seismic survey design
and field experience. See Ex. 2042 ¶ 18; Ex. 1002 ¶ 23. The person of
ordinary skill in the art would also be familiar with the design and operation
of marine seismic surveys including the design of seismic survey arrays
including sensors such as hydrophones, streamers, streamer positioning
devices and the associated electronic equipment for producing
representations of sub-surface geology. Ex. 1005, 1:5–35, Ex. 1004, 1:15–
68.
Petitioner identifies several reasons why one of skill in the art would
want to control and maintain consistent separations between streamers
during seismic surveys; first, it was well recognized that entanglement of the
streamers was a significant problem. Pet. 33 (citing Ex. 1004, 1:33–35).
Second, a consistent separation was important to “to optimize efficient
seismic data collection.” Id. at 33–34 (citing Ex. 1004, 1:37–44). Petitioner
argues specifically that Workman discloses this consistent control of the
streamer separation straight behind the boat, i.e. at a zero degree feather
angle, that is the same as the zero degree feather angle embodiment
described in the ’520 patent. Id. at 35–36; see also Ex. 1002 ¶ 150. Third,
Petitioner relies upon the testimony of Dr. Evans who explains that a person
of skill in the art would have known, for example, where a current was
naturally offsetting the streamers at a five degree feather angle, that
[i]n this situation, attempting to return the streamers to a zero
degree feather angle against the current may generate
hydrophone noise that adversely affects data quality. In such
situations, a person of ordinary skill would understand that it
IPR2014-00689
Patent 7, 293,520 B2
29
may be more desirable to maintain the streamers at a constant
two degree feather angle than to return the streamers to the zero
degree feather angle position.
Ex. 1002 ¶ 150. Also, Dr. Evans states that one of skill in the art would
need to match feather angles in subsequent surveys of the same geographic
area to obtain reliable 4D survey data, for example “if currents forced a
survey at time T to be conducted at a 5 degree feather angle, a survey at time
T+Δ would also need to be conducted at such a 5 degree angle to obtain
suitable data for 4D purposes. Id. at ¶ 151 (citing Ex. 1012 (David H.
Johnston et. al., “Time-Lapse Seismic analysis of the North Sea Fulmer
Field,” SEG Extended Abstracts (1997)) (“Johnston”) at 890. In addition,
Dr. Evans testifies that because Workman could identify and control the
streamers “it also would have been possible to adapt Workman so that its
control system could include a parameter that measured the feather angle
between streamers.” Id. at ¶ 153.
Patent Owner contends that Dr. Evan’s testimony is insufficient and
conclusory because Workman does not provide a teaching or reason to make
the necessary modification and that Dr. Evan’s testimony is improperly
based on hindsight. Patent Owner argues also that “Petitioner does not
explain how or why one of ordinary skill in the art would convert
Workman’s passive system into one that actively steers streamers such that
the streamers are maintained in desired configurations. PO Resp. 33–34
(citing Ex. 2042 ¶¶ 199–200).
We are not persuaded by Patent Owner’s initial position that
Workman itself does not provide a teaching or reason to use a feather angle
to facilitate control of the streamers. Petitioner relies on its expert, Dr.
Evans and the level of ordinary skill in the art to supply the necessary
IPR2014-00689
Patent 7, 293,520 B2
30
reasoning and rationale for its obviousness analysis with respect to use of a
feather angle to control the streamers. There is no legal requirement that the
asserted reasoning or rationale be predicated on a teaching or suggestion in
the reference. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 419 (2007)
(“The obviousness analysis cannot be confined by a formalistic conception
of the words teaching, suggestion, and motivation, or by overemphasis on
the importance of published articles and the explicit content of issued
patents.”).
The question of obviousness in this proceeding for claims 2 and 19
rests on whether Dr. Evans has provided a persuasive articulated reasoning
based on rational underpinnings to support the contention that one of
ordinary skill in the art having familiarity with the design and operation of
marine seismic surveys, seismic survey arrays including sensors such as
hydrophones, streamers, streamer positioning devices and the associated
electronic equipment, would have modified Workman to use a feather angle
to control streamer positioning. Without this, Petitioner’s contentions would
therefore appear to be the result of hindsight analysis as Patent Owner
asserts. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006), (cited with
approval in KSR, 550 U.S. at 418.)
Dr. Evans testifies persuasively that during collection of seismic data
it was important to attempt to achieve a fairly consistent and straight
streamer array behind the boat towing the array and along the plotted survey
route, or line, and that maintaining “uniform streamer separation along the
course of a planned survey line was a predictable solution to a problem that
had been known in the art, because it would lead to a collection of the data at
set streamer separations along the planned and desired survey line.” Ex.
1002 ¶ 146. Dr. Evans also testifies persuasively that streamer feathering
IPR2014-00689
Patent 7, 293,520 B2
31
was a known factor in seismic surveys where currents forced the streamers
out of alignment behind the boat and “a marine seismic surveyor must be
prepared to correct the recorded data where streamers are feathered and data
collection does not follow the predetermined survey path.” Id. Based on
this, Dr. Evans states that in order to optimize data collection, “a person of
ordinary skill would have been motivated to, at minimum, set and maintain
the streamers at a zero degree feather angle offset.” Id. at ¶ 149.
What is not immediately clear from Petitioner’s argument is why
prescribing a specific offset “feather angle” value to the streamers
positioning determination system would have been apparent to one of skill in
the art. But to this point, Dr. Evans directs us to Workman for evidence that
it was a “well-known problem that the noise produced by streamer
positioning devices can reduce seismic data quality in certain situations.” Id.
at ¶ 150 (citing Ex. 1004, 1:62–2:9). We further ascertain from Dr. Evans
testimony that when streamers are offset from the line of survey for instance
by five degrees, “[i]n this situation, attempting to return the streamers to a
zero degree feather angle against the current may generate hydrophone noise
that adversely affects data quality.” Id. Based on these evidentiary
underpinnings, Dr. Evans reasons that
A person of ordinary skill would understand that it may be
more desirable to maintain the streamers at a constant two
degree feather angle than to return the streamers to the zero
degree feather angle position. It was well-known to persons of
ordinary skill that maintaining a straight and constant feather
angle—even if non-zero—would produce more reliable seismic
data than data retrieved from a cable that was not set and
maintained in a straight configuration.
Id. This reasoning is persuasive because it explains why one of ordinary
skill in the art would have been motivated to use a specific feather angle
IPR2014-00689
Patent 7, 293,520 B2
32
value to determine streamer positioning apart from that imparted by a cross-
current (five degrees) and different also from the streamers being
repositioned to an alignment straight behind the boat towing the array i.e.
zero degrees. In this scenario, by moving the streamers from five degrees, to
a two degree feather angle, the data collection quality would be better and
the noise generated by the SPD’s would not be as great as if the streamers
were returned to the zero degree offset straight behind the boat and aligned
with the plotted survey line.
The remainder of Patent Owner’s arguments with respect to the lack
of obviousness for “feather angle mode,” rely upon improper interpretation
of the term “control mode.” PO Resp. 32–34. Patent Owner reiterates their
argument that “one of ordinary skill would not have modified Workman to
include an actively steered streamer array that attempts to maintain a certain
feather angle as recited in the challenged claims.” Id. at 33 (emphasis
added). As discussed above in our claim construction, we do not construe
“control mode” to include “active steering” but as “operational state.” We
appreciate also, as Petitioner argues, that Dr. Triantafyllou is an expert in the
field. See PO Resp. 33 (citing Ex. 2042 ¶¶ 1–11, 98, 105, 199–200).
However, Dr. Triantafyllou’s testimony refuting Dr. Evans’s testimony is
based on an erroneous claim construction that includes the requirements that
the claims at issue require, “continuously steering” and “active control” of
the streamers. See Ex. 2042 ¶ 200 (Dr. Triantafyllou states, for example,
that nothing Dr. Evans or Petitioner can point to “would have prompted a
POSA to modify Workman’s noise-reduction system to continually steer
streamer positioning devices to maintain a specified streamer separation or
feather angle.”). We are not persuaded by these contentions that Dr. Evan’s
testimony should be disregarded.

3. Secondary Considerations
Patent Owner has proffered certain evidence of secondary
considerations which we address here. PO Resp. 47–49. The factual
inquiries for obviousness include secondary considerations based on
evaluation and crediting of objective evidence. Graham v. John Deere Co.,
383 U.S. 1, 17 (1966). However, to accord substantial weight to objective
evidence requires the finding of a nexus between the evidence and the merits
of the claimed invention. In re GPAC Inc., 57 F.3d 1573, 1580 (Fed. Cir.
1995); see also In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996) (“success is
relevant in the obviousness context only if there is proof that the sales were a
direct result of the unique characteristics of the claimed invention.”).
Patent Owner contends that certain evidence from the ION lawsuit
and from the Declaration of Robin Walker, (Ex. 2077), Patent Owner’s
former Vice President of Sales and Marketing Director, establishes a long-
felt need and commercial success of the patented inventions. PO Resp. 48–
49. Specifically, Patent Owner argues that “the record evidence during the
ION litigation established the long-felt need and commercial success of the
patented inventions, as well as initial industry skepticism followed by praise
once the inventions were commercialized.” Id. at 47. In support of this
argument, Patent Owner refers to a variety of trial testimony exhibits from
the ION lawsuit, including the testimony of Mr. Walker (Ex. 2034), Mr.
Tom Scoulios (Ex. 2035), and Mr. Robert Brune (Ex. 2036). Id. With
respect to the trial testimony of Messrs. Walker, Brune and Scoulios, Patent
Owner merely provides citations to purportedly relevant portions of Exhibits
2034, 2035, 2036, stating only:
(See, e.g. Ex. 2034, Excerpt of Trial Testimony of Robin

survey systems);Ex. 2035, Excerpt of Trial Testimony of Tom
Scoulios, at 290:4-291:16 and 293:10-18 (evidencing long-felt
need for lateral steering system and failure of others to solve the
problem with tail buoy systems); Ex. 2036, Excerpt of Trial
Testimony of Robert Brune, at 3997:19-3999:7 (evidencing
long-felt need for the claimed system, failure of others to solve
the problem solved by the claimed system, and industry praise
for the claimed system).)
Id. at 47–48. Patent Owner argues that these generic references to trial
testimony from district court litigation support a finding of long-felt need but
does not explain with any detail why, or how, the referenced testimony,
evidences a long-felt need, failure of others, or industry praise. In this
regard, we limit our review to evidence actually discussed in Patent Owner’s
Response. We will not play archeologist with the record to discover
evidentiary support for bare attorney argument made in such a response. See
Google Inc. v. ART+COM Innovationpool GmbH, Case IPR2015-00788,
slip. op. at 10 (PTAB Sept. 2, 2015) (Paper 7) (citing 37 C.F.R.
§ 42.104(b)(5) (“The Board may exclude or give no weight to the evidence
where a party has failed to state its relevance or to identify specific portions
of the evidence that support the challenge.”)). We decline to consider,
moreover, information presented in an Exhibit, but not discussed sufficiently
in Patent Owner’s Response. See PO Resp. 47 (citing Ex. 2035 and 2036,
without any discussion of that evidence). Among other reasons, doing so
would permit the use of declarations to circumvent our rules relating to page
limits. In that regard, our rules prohibit a party from incorporating by
reference from one document (such as a supporting declaration) into another
document (such as Patent Owner’s Response). See 37 C.F.R. § 42.6(a)(3).
Patent Owner argues that the Declaration of Robin Walker is firsthand
evidence of industry praise “and how WesternGeco’s revolutionary lateral
IPR2014-00689
Patent 7, 293,520 B2
35
steering technology satisfied a longfelt need in the industry (Ex. 2077, ¶¶
12–37) and ultimately contributed to billions of dollars in revenue (Ex. 2077,
¶¶ 47–51).” PO Resp. 48. Patent Owner, however, does not explain
adequately how the Q-Marine product allegedly embodies the challenged
claims in the ’520 patent. Mr. Walker states specifically that
[t]hrough its provision of WesternGeco’s patented lateral
steering technology, Q-Marine satisfied a significant,
previously unmet need in the industry for better quality data
and more cost-effective surveys by offering numerous benefits,
including those detailed below.
Ex. 2077 ¶ 12. The benefits described in the subsequent paragraphs of Mr.
Walker’s Declaration are apparently based on lateral steering technology,
with the result that “better data quality could be achieved without the risk of
costly downtime and damage due to streamer tangling.” Id. at ¶ 15. It may
be that Q-Marine provides a better, faster, more reliable and commercially
successful 4D survey, but any commercial success enjoyed by the Q-Marine
product is relevant only if the challenged claims are shown to embody those
products. Patent Owner has not made out that critical showing. See In re
DBC, 545 F.3d 1373, 1384 (Fed. Cir. 2008) (finding no nexus, absent
evidence that “the driving force behind [the allegedly successful product’s
sales] was the claimed combination”); Ormco Corp. v. Align Technology
Inc., 463 F.3d 1299, 1311–12 (Fed. Cir. 2006) (requiring a “nexus between
the claimed invention and the commercial success”); Huang, 100 F.3d at 140
(requiring proof that sales were a “direct result of the unique characteristics
of the claimed invention”). In the alternative, Patent Owner’s evidence of
commercial success does not outweigh the strong showing of obviousness
made out by Petitioner in view of Workman. See Sud-Chemie, Inc. v.
Multisorb Techs., Inc., 554 F.3d 1001, 1009 (Fed. Cir. 2009) (“evidence of
IPR2014-00689
Patent 7, 293,520 B2
36
unexpected results and other secondary considerations will not necessarily
overcome a strong prima facie showing of obviousness”). Accordingly, the
alleged commercial success of the Q-Marine product does not support a
conclusion of nonobviousness of the challenged claims in this case.
Additionally, based on our obviousness analysis of the dependent
claims, above, because claims 2 and 19 include all the limitations recited in
respective independent claims 1 and 18, claims 1 and 18 are also obvious
based on our conclusion of obviousness of claims 2 and 19. See Soverain
Software LLC v. Victoria’s Secret Direct Brand Mgmt., LLC, 778 F.3d 1311,
1315 (Fed. Cir. 2015; Ormco v. Align Tech., 498 F.3d 1307, 1319 (Fed. Cir.
2007) (when a dependent claim is “found to have been obvious, the broader
claims . . . must also have been obvious”).
Accordingly, we conclude Petitioner has established by a
preponderance of evidence that claims 1, 2, 18, and 19 would have been
obvious under 35 U.S.C. § 103 in view of Workman.
C. Claims 1, 2, 18 and 19 – Anticipation by Hedberg
Petitioner asserts that claims 1, 2, 18, and 19 are anticipated by
Hedberg. Pet. 38–46. Patent Owner contends among other things that
Hedberg does not disclose “an array of streamers each having a plurality of
streamer positioning devices there along,” because the embodiment
disclosing multiple SPD’s on a single streamer is a different and disparate
embodiment from those disclosing multiple streamers, which only disclose a
single paravane on each streamer. PO Resp. 34–35. We have reviewed the
parties’ submissions and evidence discussed in those papers, and are not
persuaded, by a preponderance of the evidence, that claims 1, 2, 18, and 19
are anticipated by Hedberg.
IPR2014-00689
Patent 7, 293,520 B2
37
1. Overview of Hedberg
As illustrated below, Hedberg discloses a marine seismic exploration
system including a streamer (cable) 10 towed behind vessel 2, the streamer
having a plurality of echo sensors 6 (such as hydrophones) for sensing the
echo of an impulse generating device. Ex. 1005, 1:3–13, 37–38.

The streamer is controlled by steerable paravane 18b connected to the
streamer so as to be accurately towed along survey line 26. Id. at 1:18–30.
As shown below in Figure 8, in another embodiment Hedberg also describes
a streamer array for establishing a 3-dimensional sea floor profile, including
three (3) parallel streamers 4a–c towed by the vessel. Id. at 6:10–19.
IPR2014-00689
Patent 7, 293,520 B2
38

To obtain an accurate 3-dimensional survey, the vessel tows streamers 4b
and 4c, maintained in a spaced apart, parallel arrangement by paravanes 81a
and 81c on either side of middle streamer 4a. Id. at 6:14–19.
In yet another embodiment, in order to overcome streamer positioning
deviations, Hedberg discloses in Figures 10 and 11, shown below, streamer
90 controlled by a plurality of paravanes 92. Id. at 6:33–42.

Figure 10 depicts a top view of streamer 90 having a plurality of paravanes
92 connected along the length of the streamer for controllably steering the
streamer.

IPR2014-00689
Patent 7, 293,520 B2
39
Figure 11 illustrates a side view streamer 90 and paravanes 92. Hedberg
further explains that the “paravanes are provided with rudders and elevators
or other steerable means . . . by which the position of the paravane, and the
various elements or devices connected thereto, can be established and
maintained.” Id. at 6:41–46. The paravanes are described by Hedberg as
carrying a radar reflector 96 corresponding to a radar control 98 on the
vessel which determines positioning of the paravane and issues signals to
steering motor 100 in the paravane to adjust the paravane rudders 94 “to
maintain them in predetermined and accurate positions with respect to each
other.” Id. at 6:52–54.
2. Claims 1, 2, 18, and 19
The basis for Petitioner’s anticipation argument is its assertion that
Hedberg discloses a steerable marine seismic survey device having multiple
streamers and steerable paravanes, i.e. an array, including “hydrophones or
other echo responsive means at predetermined points spaced apart in two
directions to provide a “cross spread’ within a horizontal plane.” Ex: 1005,
1:75–2:2, Fig. 8, see also Pet. 38. Petitioner contends specifically that an
array of “hydrophone spreads,” understood in the field as “streamers” are
disclosed by Figure 8, shown above, specifically disclosing “the use of
multiple spreads connected to recording instruments for developing three
dimensional records of the profiles of areas under survey.” Pet. 38 (citing
Ex. 1005, 6:12–16). Petitioner further argues that collectively with the array
shown in Figure 8 the embodiments disclosed in Hedberg’s Figures 10–12
detail a streamer 90 having multiple paravanes, thereby “confirm[ing] that
Hedberg discloses a plurality of paravanes (labeled 92) attached to each
streamer.” Id. at 39.
IPR2014-00689
Patent 7, 293,520 B2
40
Although the embodiments in Hedberg provide certain similar
disclosures, we are not persuaded that they disclose a single known marine
seismic array system having multiple streamers each controlled by multiple
SPD’s that anticipates the challenged claims. Anticipation requires that
every limitation of the claim at issue be disclosed in a prior art disclosure
and “arranged or combined in the same way as recited in the claim.” Net
MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008). “[I]t
is not enough that the prior art reference . . . includes multiple, distinct
teachings that the artisan might somehow combine to achieve the claimed
invention.” Id.; see also Kyocera Wireless Corp. v. ITC, 545 F.3d 1340,
1351–52 (Fed. Cir. 2008) (concluding that a set of eleven specifications
pertaining to the same telecommunication standard did not constitute a
“single prior art reference”).
Petitioner does not specifically argue that a single embodiment
discloses all limitations of the challenged claims, instead relying on different
embodiments as allegedly disclosing the array of streamers (Figure 8), and
multiple SPD’s on a single streamer (Figures 10–12). See Pet. 38–39. The
relied upon embodiments undoubtedly are similar, as they each describe
using SPD’s to control streamer positions. There are differences, however,
as, on one hand
[a]s shown in FIG. 8, such spreads may be arranged in three
parallel lines extending parallel to the direction of transverse of
the area under survey, and the three records which are obtained
can be utilized to establish a three dimensional profile or the
seismic interface of the area under survey.
Ex. 1005, 6:14–19. On the other hand, Figures 10–12 are directed to a
preferred embodiment for “a conventional spread of hydrophones, located in
a single dimension of a horizontal plane.” Ex. 1005 6:27–29. It is not clear
IPR2014-00689
Patent 7, 293,520 B2
41
from our review of the written description in Hedberg that these
embodiments are intended either expressly or inherently to be
comprehensive or inclusive, in other words, as if the multiple SPD’s on the
single streamer embodiment are to be employed in the multiple spread
arrangement detailing only a single SPD on each streamer.
Given that the prior art teachings and suggestions are found in
different embodiments describing on one hand an array, as opposed to a
single streamer embodiment, we find that one skilled in the art would not
have at once envisaged the claimed arrangement of known components in a
manner consistent with anticipation under 35 U.S.C. § 102. Petitioner has
not demonstrated, by a preponderance of the evidence, therefore, that claims
1, 2, 18 and 19 of the ’520 patent are anticipated by Hedberg.
D. Claims 1, 2, 18, and 19 – Obviousness over Hedberg
Petitioner’s obviousness analysis with respect to Hedberg fails to
provide any explanation or an articulated reasoning based on rational
underpinnings, as to why one of ordinary skill in the art would have
modified Hedberg’s multiple streamer embodiment to include streamers
provided with a plurality of SPD’s. Pet. 46–49. Patent Owner argues that
Petitioner has failed to explain why one of ordinary skill in the art would
modify Hedberg to include a plurality of paravanes along the length of the
single front-end paravane multiple streamer embodiment. PO Resp. 43–44.
Patent Owner relies on its expert for support that adding further paravanes to
Hedberg’s streamer array would not be obvious to one of ordinary skill in
the art. Id. To this point, Dr. Triantafyllou states that “Hedberg proposes
the use of radar reflections in order to control the paravanes — but there is
no recognition of the unique problems associated with lateral control of
seismic streamers and streamer positioning devices.” Ex. 2042 ¶ 127.
IPR2014-00689
Patent 7, 293,520 B2
42
The entirety of Petitioner’s obviousness analysis in the Petition with
respect to Hedberg is directed to the obviousness of the claimed “streamer
separation mode,” and “feather angle mode.” PO Resp. 43. Failing to
address and provide sufficient articulated reasoning for modifying Hedberg
to meet the limitations of independent claims 1 and 18, Petitioner has not
sustained their initial burden of factually supporting a prima facie conclusion
of obviousness. The key to supporting any prima facie conclusion of
obviousness under 35 U.S.C. § 103 is the clear articulation of the reason(s)
why the claimed invention would have been obvious. The Court in KSR
(550 U.S. at 418) noted that the analysis supporting a rejection under 35
U.S.C.§ 103 should be made explicit. “[R]ejections on obviousness grounds
cannot be sustained by mere conclusory statements; instead, there must be
some articulated reasoning with some rational underpinning to support the
legal conclusion of obviousness” Kahn, 441 F.3d at 988, (cited with
approval in KSR, 550 U.S. at 418.)
Accordingly, Petitioner has not demonstrated, by a preponderance of
the evidence that claims 1, 2, 18 and 19 of the ’520 patent are obvious over
Hedberg.
E. Time Bar under 35 U.S.C. § 315(b)
Patent Owner makes several arguments in support of its position that
the PGS IPR is time-barred under 35 U.S.C. § 315(b). We address each of
Patent Owner’s arguments below. PO Resp. 49–59.
1. Whether ION is an Unnamed RPI
The statute governing inter partes review proceedings sets forth
certain requirements for a petition for inter partes review, including that “the
petition identif[y] all real parties in interest.” 35 U.S.C. § 312(a) (emphasis
added); see also 37 C.F.R. § 42.8(b)(1) (requirement to identify real parties
IPR2014-00689
Patent 7, 293,520 B2
43
in interest in mandatory notices). The Office Patent Trial Practice Guide, 77
Fed. Reg. 48,756, 48,764 (Aug. 14, 2012) (“Practice Guide”) explains that
“[w]hether a party who is not a named participant in a given proceeding
nonetheless constitutes a ‘real party-in-interest’ . . . to that proceeding is a
highly fact-dependent question.” 77 Fed. Reg. at 48,759. The Practice
Guide further states that: [h]owever, the spirit of that formulation as to IPR
and PGR proceedings means that, at a general level, the “real party-in-
interest” is the party that desires review of the patent. Thus, the “real party-
in-interest” may be the petitioner itself, and/or it may be the party or parties
at whose behest the petition has been filed. Id. The determination of
whether a party is an RPI is a “highly fact-dependent question” (id.), in
which the focus is on the party’s relationship to the inter partes review
pending before the Board, and the degree of control the party can exert over
the proceeding. See Aruze Gaming Macau, Ltd. v. MGT Gaming, Inc., Case
IPR2014-01288, slip op. at 11 (PTAB Feb. 20, 2015) (Paper 13). “[I]f a
nonparty can influence a petitioner’s actions in a proceeding before the
Board, to the degree that would be expected from a formal co-petitioner, that
nonparty should be considered an RPI to the proceeding.” Id. at 12.
Patent Owner asserts in its Response that ION is a real party-in-
interest under the factors set forth in our Practice Guidelines because (a)
Petitioner invoked ION’s indemnity obligations by notifying ION that
Petitioner expected ION to fulfill its obligations and pay for the lawsuit and
this IPR proceeding; (b) ION was obligated to pay for this IPR and was
instrumental in developing invalidity theories, thus giving ION an “interest,
opportunity to control, and active control over the Petition;” and (c)
Petitioner is ION’s proxy due to ION’s obligation under the indemnification
agreement. PO Resp. 53– 54.
IPR2014-00689
Patent 7, 293,520 B2
44
Patent Owner’s main contention for indemnification, and thus control
by ION, focuses on an indemnification provision in the 2008 Master
Purchase Agreement (Ex. 2069, “Agreeement”) between PGSAS and
Concept Systems Limited (“Concept”), an ION subsidiary. Id. at 49–50.
The Agreement is considered protective order material in this proceeding.
See Ex. 2069.
Patent Owner argues that the indemnification provision “reasonably
includes defending against an infringement lawsuit, proving the invalidity of
a patent in a review proceeding, and obtaining a license.” PO Resp. 50.
Patent Owner contends that Petitioner invoked this indemnification in its
letter of November 13, 2012 to ION citing the above indemnification
provision and stating “[i]f it turns out that ION or its affiliates did not have
the proper patent licenses for the DigiFIN equipment and related
components and services it sold us, we expect that ION will provide us with
appropriate remedies.” Ex. 2027. Patent Owner concludes that “ION thus
has control, or at least the opportunity to control, the selection and
implementation of a remedy that includes filing a petition for review.” PO
Resp. 51.
As an initial matter, nowhere in the asserted provision of the
Agreement does it state that Concept (ION) has the right, or obligation, to
defend a lawsuit or control litigation, a lawsuit, or undertake any type of
invalidity proceedings such as the present IPR. We agree with Patent Owner
that a reasonable interpretation of the indemnification provision could
include obtaining a license. Id. at 50. There is, however, no express
language or evidence that Patent Owner points to that persuades us to
interpret the language of the indemnification provision as requiring ION to
“defend a lawsuit,” and thus extend the provision to include a specific
IPR2014-00689
Patent 7, 293,520 B2
45
obligation to defend, or pay for, a lawsuit filed against Petitioner or to
undertake an IPR proceeding. Petitioner’s letter of November 13, 2012,
does not actually “invoke” any certain part of the Agreement or refer to any
necessity for ION to step in and defend a lawsuit, the letter refers only to
“appropriate remedies.” See Ex. 2027. In fact, a previous email sent July 6,
2012 from Phillip Shotts of ION to Kevin Hart at PGS, summarizing ION’s
Product Assurance Pledge, also does not specify or imply any obligation on
the part of ION to defend PGS from a lawsuit, reimburse or pay for a
lawsuit, or file an invalidity proceeding. See Ex. 2022.
Based on the record before us ION does not have an obligation to step
in and defend Petitioner against a lawsuit or to otherwise pay for the defense
of a lawsuit and advance Petitioner as ION’s proxy. The mere existence of
an indemnification agreement does not establish that the indemnitor has the
opportunity to control an inter partes review. For example, “[t]he mere
existence of an indemnification agreement [however] does not establish that
the indemnitor has the opportunity to control an inter partes review.” Nissan
North America, Inc. v. Diamond Coating Tech., LLC, Case IPR2014- 01546,
slip. op. at 7 (PTAB Apr. 21, 2015) (determining that the existence of an
indemnification agreement was not sufficient to establish that the unnamed
parties were real parties-in-interest to the inter partes review proceeding)
Patent Owner argues still further that the nature of Petitioner and
ION’s close relationship shows that ION is controlling, or has the ability to
control this IPR as an RPI. PO Resp. 51–53. Patent Owner argues
specifically that “Petitioner and ION have coordinated efforts across
multiple forums to promote their joint interests regarding the ’520 patent,”
and that a common interest privilege was asserted by Petitioner over
communications between ION and Petitioner. Id. at 52. There is nothing
IPR2014-00689
Patent 7, 293,520 B2
46
surreptitious about separate entities, as either third parties, or separate parties
to a legal action, proclaiming shared interests to protect communications that
are relevant to advance the interests of the entities possessing the common
interest. See In re Regents of Univ. of California, 101 F.3d 1386, 1389 (Fed.
Cir. 1996) (“The protection of communications among clients and attorneys
‘allied in a common legal cause’ has long been recognized.”) (quoting In re
Grand Jury Subpoena Duces Tecum, 406 F.Supp. 381, 386 (S.D.N.Y.1975)).
The fact that Petitioner and ION, have a desire, and common interest, in
invalidating the ’520 patent and other WesternGeco patents, and have
collaborated together, and invoked a common interest privilege with respect
to sharing potentially invalidating prior art references, does not persuade us
that ION has the ability to control the instant Petition or is directing or
funding the present proceeding.
With respect to the ability to control, the Board has issued decisions
determining based on evidence of control that a non-party entity is a real
party-in-interest. See Zoll Lifecor Corp. v. Philips Elecs. North America
Corp., Case IPR2013-00609 (PTAB Mar. 20, 2014) (Paper 15) (the “Zoll
Decision”). In the Zoll Decision, the Board was persuaded that an unnamed
party to the IPR, Zoll Medical, exercised consistent control over Zoll
Lifecore for over six years, including control of the inter partes review. Id.
at 11. Specific evidence of control included Zoll Lifecor’s acknowledgment
that Zoll Medical controlled 100% of Zoll Lifecor and approved Zoll
Lifecor’s corporate budget and plans. Id. Other evidence of control
included the fact that common counsel for Zoll Medical and Zoll Lifecor
would not state affirmatively that counsel did not provide input into
preparation of the IPRs. Id. at 11–12. Additional evidence showed that only
IPR2014-00689
Patent 7, 293,520 B2
47
Zoll Medical’s management team attended court-ordered mediation in the
underlying district court litigation filed against Zoll Lifecor. Id. at 12.
We have no such evidence in this proceeding. ION and Petitioner are
not related corporate entities. The evidence of record here shows that
Petitioner and ION preliminarily discussed potential remedies relating to the
product itself, not indemnification from litigation. Exs. 2022, 2027. As
discussed above, absent specific facts evidencing the contractual obligations
of the parties, we are not apprised of any evidence from the Agreement
indicative of control, or potential to control, this inter partes proceeding by
ION. Furthermore, based on the record before us, Patent Owner has not
established that ION has the ability or opportunity to control the present
proceeding to the degree that would be expected from a formal copetitioner.
As such, we are not persuaded that ION is an RPI to this proceeding, and the
fact that the PGS Petition does not identify ION does not prevent the Board
from considering Petitioner’s grounds of unpatentability.
2. Additional Discovery
Patent Owner next argues that the Board prejudicially denied Patent
Owner additional discovery on the RPI after “Petitioner failed to forthrightly
answer Interrogatory No. 5.” PO Resp. 56–57 (citing Ex. 2018 at 14). Our
review of Exhibit 2018 indicates that contrary to Patent Owner’s assertion,
Petitioner unambiguously affirmed that Petitioner had made no claims or
demands to ION for indemnity with respect to the ’520 patent. Patent
Owner also asserts that the Agreement, Exhibit 2069 was not available to the
Board prior to our Decision to Institute. Id. at 57. As discussed above
Exhibit 2069 is now available, and having been considered, for the reasons
set forth above, does not alter our underlying determination above that ION
is not a real party-in-interest.
IPR2014-00689
Patent 7, 293,520 B2
48
3. Multi Klient
Patent Owner argues that a new, and allegedly wholly owned
subsidiary of Petitioner, Multi Klient Invest AS (“Multi Klient”), has been
revealed in the district court litigation as an “interest[ed] parties concerning
the subject matter of the ’520 patent.” PO Resp. 57–58 (citing Ex. 2076).
The fact that Multi Klient may be related to Petitioner and is indicated as
having a financial interest in the outcome of litigation, however, does not by
itself indicate that Multi Klient has any ability to control the present IPR
proceeding. See Ex. 2076 (referring to Paragraph 2 of Order for Pretrial
Conference as determinative of “financially interested” defendants.)
Accordingly, we are not persuaded on these facts that Multi Klient is an RPI
to this proceeding and deny Patent Owner’s request for additional discovery
into this matter.
4. Service
Under 35 U.S.C. § 315(b), a party may not file a petition for inter
partes review if the party had been served with a complaint alleging
infringement more than one year previously. Patent Owner argues that
Petitioner was subpoenaed and “appeared” in the ION litigation prior to
being “served” with a complaint alleging infringement of the ’520 patent on
March 14, 2011, and, therefore, “Petitioner’s one year clock to file a petition
started ticking at this time.” PO Resp. 59.
A review of the litigation history establishes that on June 12, 2009,
Patent Owner filed, via the court’s electronic case filing procedure (“ECF”),
a complaint initiating the ION lawsuit, alleging infringement of the ’520
patent against ION based on ION’s “DigiFIN” and other products. Ex.
2007. Patent Owner also filed a similar complaint against a company called
Fugro, a customer of ION, which was consolidated with the ION lawsuit.
IPR2014-00689
Patent 7, 293,520 B2
49
Ex. 2037. On December 8, 2009, remarking that Petitioner may have been
involved in the design and testing of the ION products, Patent Owner
provided Petitioner via email with a copy of the complaint against ION. Ex.
2008. Subsequently, Patent Owner subpoenaed Petitioner on January 22,
2010 to produce documents and evidence relating inter alia to Petitioner’s
use and operation of ION’s DigiFIN product. Ex. 2009. In response to the
subpoena, Petitioner appeared in the ION lawsuit through its counsel, Heim,
Payne & Chorush. Ex. 2011. On March 14, 2011, Patent Owner filed an
amended complaint in the ION lawsuit via the court’s electronic filing
system (“ECF”), naming ION and Fugro, but not Petitioner. Ex. 2012.
Patent Owner apparently believes that because Petitioner’s counsel, as an
ECF notice recipient in the ION lawsuit, received a copy of the amended
complaint against Fugro and ION on March 14, 2011, Petitioner was
therefore “served” in accordance with 35 U.S.C. § 315(b) the same day. See
PO Resp. 59. Thus, it is Patent Owner’s position that because Petitioner was
“served” with the complaint more than one year before filing, the Petition
here is now time-barred.
The Board has dealt with similar arguments regarding the statutory
interpretation of 35 U.S.C. § 315(b) before in Motorola Mobility LLC v.
Arnouse Digital Devices Corp., Case IPR2013-00010 (PTAB Jan. 30, 2013)
(Paper 20) (the “Motorola decision”). For reasons similar to those set forth
in the Motorola decision, we do not adopt the statutory construction that
mere receipt of a complaint, via email or even ECF, initiates the one-year
time period. We specifically agree with the Motorola Panel’s review and
interpretation of the legislative history and intent of 35 U.S.C. § 315(b) in
that, “[w]e do not believe that the Congress intended to have the time period
start before a petitioner is officially a defendant in a law suit.” Id. at 5.
IPR2014-00689
Patent 7, 293,520 B2
50
Patent Owner specifically argues that the present proceeding differs
from Motorola because in the ION lawsuit “Petitioner was served with
process and formally appeared,” (emphasis omitted) and was thus “‘brought
under a court’s authority, by formal process’ before being served with the
amended complaint.” Prelim. Resp. 7–8 n.1 (citing Murphy Bros., Inc. v.
Michetti Pipe Stringing, Inc. 526 U.S. 344, 347 (1999)). Despite this factual
difference from Motorola, Petitioner was not, and never has been, a party
defendant in the ION lawsuit.
Petitioner, in the ION lawsuit, was served under Fed. R. Civ. P. 45,
with a third party subpoena, to produce documents and things relating to the
ION lawsuit. See Ex. 2009. Although a person, or entity, may have been
served properly with a subpoena, and may fall under a court’s authority for
purposes of producing appropriate documents and things not protected by a
privilege or protection, Fed. R. Civ. P. 45(c)–(e) does not express, or imply,
that a person subject to the subpoena is a “defendant” to a lawsuit. Indeed,
Fed. R. Civ. P. 45 specifically differentiates between a “person” served with
the subpoena, and “a party” to the lawsuit. See Fed. R. Civ. P. 45 (d)(2)(B)
(“A person commanded to produce documents or tangible things or to permit
inspection may serve on the party or attorney designated in the subpoena a
written objection to inspecting, copying, testing or sampling any or all of the
materials.”). We are aware of no case law or precedent, nor has Patent
Owner cited to any, indicating that serving a person with a subpoena, and
subjecting them to the authority of the court in enforcing such subpoena
under Fed. R. Civ. P. 45(e), provides sufficient legal process to make such
person a defendant to a lawsuit.
Thus, Petitioner was not a defendant in the ION lawsuit. Concomitant
with our colleagues’ Motorola decision, we interpret 35 U.S.C. § 315(b) as

requiring service upon a defendant to the lawsuit. Petitioner was not a
defendant; thus, it was never “served with a complaint” in the ION lawsuit
as required by 35 U.S.C. § 315(b).

IV. MOTION TO EXCLUDE EVIDENCE
Petitioner filed a Motion to Exclude Evidence seeking to exclude
portions of the testimony of Robin Walker (Ex. 2077) and numerous other
exhibits submitted by Patent Owner. Paper 85. The party moving to
exclude evidence bears the burden of proving that it is entitled to the relief
requested—namely, that the material sought to be excluded is inadmissible
under the Federal Rules of Evidence. See 37 C.F.R. §§ 42.20(c), 42.62(a).
Even without excluding this evidence, we have determined that Petitioner
has established, based on a preponderance of the evidence, the
unpatentability of claims 1, 2, 18 and 19 of the ’520 patent. Furthermore,
from Petitioner’s listed Exhibits on page 1 of its Motion to Exclude, our
Decision includes only references to Exhibits 2007, 2012, 2034–36, and
2077. Exhibits 2007 and 2012 are referred to merely for background
procedural dates, Exhibits 2034–2036 are identified as not being considered,
and for Exhibit 2077, Petitioner’s hearsay arguments do not pertain to the
particular paragraphs of Mr. Walker’s testimony that we substantively
considered. See Section III.B.
For these reasons, we deny Petitioner’s Motion to Exclude.

Patent Owner’s argument that S.D. Texas L.R. 5-1 “comports” (PO Resp.
59) with the proper interpretation of service under §315(b) is not persuasive
as to the intent of Congress with respect to §315(b). See 157 Cong. Rec.
S5429 (daily ed. Sept. 8, 2011) (statement of Senator Kyl) (“it is important
that the section 315(b) deadline afford defendants a reasonable opportunity
to identify and understand the patent claims that are relevant to the
litigation”).

V. CONCLUSION
We conclude that Petitioner has demonstrated by a preponderance of
the evidence that (1) claims 1 and 18 of the ’520 patent are anticipated by
Workman, and (2) claims 1, 2, 18, and 19 of the ’520 patent are unpatentable
as obvious over Workman.
This is a final written decision of the Board under 35 U.S.C. § 318(a).
Parties to the proceeding seeking judicial review of this decision must
comply with the notice and service requirements of 37 C.F.R. § 90.2.
VI. ORDER
For the reasons given, it is
ORDERED that claims 1, 2, 18, and 19 of U.S. Patent No. 7, 293,520
are determined by a preponderance of the evidence to be unpatentable;
FURTHER ORDERED that Patent Owner’s request for additional
discovery with respect to Multi Klient AS is denied;
FURTHER ORDERED that Petitioner’s Motion to Exclude is denied;
and
FURTHER ORDERED that because this is a final written decision,
parties to the proceeding seeking judicial review of the decision must
comply with the notice and service requirements of 37 C.F.R. § 90.2.
