`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 5 of 24
`
`Plaintiff WesternGeco L.L.C. ("WesternGeco") respectfully submits its Reply Claim
`
`Construction Brief in further support of WesternGeco's proposed constructions set forth in the
`
`parties' Joint Claim Construction and Prehearing Statement (D.I. 39).
`
`SUMMARY OF ARGUMENT
`
`WesternGeco filed its Complaint on June 12, 2009 to halt ION Geophysical Corp.'s
`
`("ION's") willful infringement ofU.S. Patent Nos. 6,932,017 ("the '017 patent"); 7,080,607 ("the
`
`'607 patent"); 7,162,967 ("the '967 patent") and 7,293,520 ("the '520 patent") (collectively, "the
`
`Bittleston patents"); and 6,691,038 ("the Zajac '038 patent"). (D.I. 1) ION filed a counterclaim
`
`for alleged infringement of one ION patent. (D.I. 6) This Reply addresses the parties' proposed
`
`constructions for the five WesternGeco patents.
`
`The Federal Circuit's 2005 en bane decision in Phillips sets forth the proper framework
`
`for claim construction. It holds that disputed claim terms are properly construed based on their
`
`ordinary meanings in the context of the patent. As set forth in WesternGeco's Opening Brief
`
`("WGOB"), WesternGeco's proposed constructions for the Bittleston and Zajac patents are based
`
`on this intrinsic record. They are properly adopted by the Court.
`
`As also set forth
`
`in WesternGeco's Opening Brief, however, ION's proposed
`
`constructions commit the "cardinal sin of claim construction" by improperly limiting
`
`WesternGeco's patents to their preferred embodiments. They violate the requirements of Phillips
`
`by: (1) reading limitations into the claims; (2) ignoring the ordinary meaning ofthe claim terms;
`
`(3) relying heavily on extrinsic evidence; (4) excluding disclosed embodiments; (5) rendering
`
`claim terms superfluous; and (6) rendering claims duplicative. As discussed below, any of these
`
`flaws would be improper. Many ofiON's proposed constructions suffer them all.
`
`ION's Response Brief ("IRB") concedes that many of its proposed constructions were
`
`improper. For some, ION now agrees with WesternGeco's proposed constructions. For others,
`
`Ex. PGS 1020
`
`

`

`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 6 of 24
`
`however, ION offers "revised" proposed constructions that merely repeat the same flaws. They
`
`still ignore the ordinary meaning of claim terms and read limitations into the claims. They still
`
`restrict the patents to preferred embodiments and exclude other embodiments. And they still
`
`render claim terms superfluous and render claims duplicative. As discussed below, ION's
`
`Response fails to even address the applicable case law cited in WestemGeco's Opening Brief.
`
`Even as "revised," ION's proposed constructions remain properly rejected.
`
`ARGUMENT
`
`I.
`
`CLAIM TERMS ARE PROPERLY CONSTRUED BASED ON THEIR
`ORDINARY MEANING IN LIGHT OF THE PATENT'S SPECIFICATION
`
`"[T]he words of a claim 'are generally given their ordinary and customary meaning' ... in
`
`the context of the entire patent, including the specification." Phillips v. AWH Corp., 415 F.3d
`
`1303, 1312-13 (Fed. Cir. 2005) (en bane). Unless unusual or technical terms are recited, claim
`
`construction can "involve little more than the application of the widely accepted meaning of
`
`commonly understood words." Id at 1314.
`
`"[W]hen the preferred embodiment is described in the specification as the invention
`
`itself, the claims are not necessarily entitled to a scope broader than that embodiment." Watts v.
`
`XL Sys., Inc., 232 F.3d 877, 882 (Fed. Cir. 2000); see also Verizon Servs. Corp. v. Vonage
`
`Holdings Corp., 503 F.3d 1295, 1308 (Fed. Cir. 2007) (construing claims in light of a description
`
`of "the present invention"); Honeywell Int'l, Inc. v. ITT Indus., Inc., 452 F.3d 1312, 1318 (Fed.
`
`Cir. 2006) (same). However, the "use of the phrase 'the present invention' does not
`
`'automatically' limit the meaning of claim terms in all circumstances." Netcraft Corp. v. eBay,
`
`Inc., 549 F.3d 1394, 1398 (Fed. Cir. 2008); Rambus, Inc. v. Infineon Techs. AG, 318 F.3d 1081,
`
`1094 (Fed. Cir. 2003) ("such language must be read in context of the entire specification"). For
`
`example, it is improper to rely on descriptions of "the present invention" to exclude other
`

`
`Ex. PGS 1020
`
`

`

`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 7 of 24
`
`disclosed embodiments. Verizon, 503 F.3d at 1305 ("We normally do not interpret claim terms
`
`in a way that excludes disclosed examples in the specification."); Colorquick, LLC v. Eastman
`
`Kodak Co., No. 6:06-CV-390, 2008 WL 5771324, at *7 n.9 (E.D. Tex. June 25, 2008)
`
`(distinguishing Honeywell on this basis).
`
`In fact, it is the "cardinal sin of claim construction" to limit claims terms to a preferred
`
`embodiment. Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1324 (Fed. Cir. 2002). It is
`
`also generally improper for a proposed construction to render superfluous other terms in the
`
`claim. Merck & Co., Inc. v. Teva Pharms. USA, Inc., 395 F.3d 1364, 1372 (Fed. Cir. 2005).
`
`And a proposed construction that would render two claims identical in scope violates the
`
`doctrine of claim differentiation. Phillips, 415 F.3d at 1314-15. Extrinsic evidence is "less
`
`significant than the intrinsic record" and cannot override these rules. /d. at 1317.
`
`II.
`
`PROPOSED CONSTRUCTIONS FOR THE BITTLESTON PATENTS
`
`(a)
`
`"streamer positioning device(s)"
`
`'017-1, 3-5,7-8, 16;
`'967-1-9, 15; '607-1,
`4-6, 8-9, 15;
`'520-1 9, 18, 26
`As set forth in WestemGeco's Opening Brief, there is no contention that "streamer,"
`
`device(s) used to steer/position the
`streamer both vertically and
`horizontally 1
`
`a device that controls the position of a
`streamer as it is towed (e.g., a "bird")
`
`"positioning" or "device" have any unusual meanings or would be confusing for a jury. (WGOB
`
`at 10-11) Therefore, this term is properly construed by "the application of the widely accepted
`
`meaning of commonly understood words." Phillips, 415 F.3d at 1314. WestemGeco's proposed
`
`construction tracks the ordinary meaning of the term, and is based on the specification's broad
`
`disclosure of various streamer positioning devices which control only vertical position, control
`
`ION's Response Brief deletes any requirement of vertical and horizontal steering for its "revised" proposed
`constructions of "global control system" and "local control system." (IRB at 7-8 & 7 n.4) However, ION has
`not similarly corrected its proposed construction of "streamer positioning device."
`
`3
`
`Ex. PGS 1020
`
`

`

`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 8 of 24
`
`only horizontal position, or control both. (WGOB at 11-12; Ex. 1 at 1 :24-27; 1 :34-36; 1 :47-52;
`
`2:5-6; 1 0:23-30)2 ION does not dispute these facts. (IRB at 4-6)
`
`ION's proposed construction improperly excludes some of these embodiments. See
`
`WGOB at 11-12; Verizon, 503 F.3d at 1305 (rejecting construction "that excludes disclosed
`
`examples in the specification"). It is additionally improper because it would render other claim
`
`language superfluous, e.g., "to steer the streamer positioning device laterally." See WGOB at 11;
`
`Stumbo v. Eastman Outdoors, Inc., 508 F.3d 1358, 1362 (Fed. Cir. 2007); Merck, 395 F.3d at
`
`1372; Phillips, 415 F.3d at 1314. And it commits the "cardinal sin of claim construction" by
`
`limiting the claim term to a preferred embodiment. See WGOB at 11-12; Ex. 1 at 3:29-30
`
`("Preferably the birds 18 are both vertically and horizontally steerable. ");3 Halliburton Energy
`
`Svcs., Inc. v. M-I LLC, 514 F.3d 1244, 1251 (Fed. Cir. 2008) (noting that the use of "preferably"
`
`"strongly suggests that ... [it] is simply a preferred embodiment"); Telejlex, 299 F.3d at 1324;
`
`DSW, Inc. v. Shoe Pavilion, Inc., 537 F.3d 1342, 1348 (Fed. Cir. 2008) ("[I]t is well-settled that
`
`claims are not to be confined to [a preferred] embodiment.").
`
`ION's Response Brief fails to address these flaws, or to even cite Phillips, Stumbo,
`
`Merck, DSW or Teleflex.
`
`(IRB at 4-6) The only purported evidence ION raises is:
`
`(1) a
`
`description of "the invention" that discusses lateral steering; (2) a disclosure of preferred
`
`"modes" purportedly including vertical and horizontal steering; and (3) extrinsic evidence. None
`
`of this supports ION's proposed construction.
`
`First, ION's purported reliance on Verizon and Honeywell for construing claim terms in
`
`2
`
`3
`
`Exs. 1-45 refer to exhibits submitted with WestemGeco's Opening Brief.
`
`Unless otherwise indicated, all emphases are added.
`
`4
`
`Ex. PGS 1020
`
`

`

`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 9 of 24
`
`light of descriptions of "the present invention" is inapposite- the passage cited by ION does not
`
`mention, much less require, vertical steering. See Ex. 1 at 2:47-60; Verizon, 503 F.3d at 1303
`
`(refusing to limit a claim where the description of "the present invention" was unrelated to the
`
`feature defendant proposed reading into the claim). It fails to support ION's argument.
`
`Second, the various "modes" recited in the Bittleston patents represent, at most, preferred
`
`or alternate embodiments. None are described as "the present invention." And, in any event,
`
`most if not all of the disclosed control modes do not require vertical steering. (Ex. 1 at 9:53-
`
`10:11; see also §II(h), infra) They fail to provide any support for ION's proposed construction.
`
`Third, ION's purported reliance on extrinsic evidence is improper because it cannot be
`
`used to contradict the intrinsic record. Phillips, 415 F.3d at 1317. Moreover, the testimony of
`
`Peter Canter which ION cites merely confirms that vertical and horizontal steering is a preferred
`
`embodiment: "It's my view that they can do depth and/or lateral positioning." (IRB Ex. A at
`
`126:22-23) The testimony of Jeffrey Wendt, also cited by ION, is similar:
`
`"the streamer
`
`steering device could -- could be laterally controlled or vertically controlled or both, depending
`
`on a client's needs."
`
`(Ex. 41 at 52:19-53:2) So is the testimony of Simon Bittleston: "It
`
`describes [depth control] as one thing that might be done, but it doesn't say that it has to be
`
`done." (IRB Ex. Cat 160:4-12) ION's extrinsic evidence merely confirms that ION's proposed
`
`construction is improper. None of ION's purported evidence overcomes the flaws of ION's
`
`proposed construction, e.g., excluding disclosed embodiments, rendering claim language
`
`superfluous and limiting the claims to a preferred embodiment. For all of these reasons - which
`
`stand unrebutted- ION's proposed construction is still properly rejected.

`
`(b)
`
`"global control system"
`
`'017-7, 8;
`'607-7, 8;
`. '967-1, 4,
`5, 8, 9,
`15
`
`"global
`control
`system"
`
`a control system that
`sends commands to other
`devices in a system (e.g.,
`local control systems)
`
`system that monitors the position of
`system that monitors the positioning of
`the streamers and provides the
`the streamers and provides the desired
`desired forces or desired positioning
`vertical and horizontal forces or
`information to the local control
`vertical and horizontal positioning
`information to the local control ~ystems systems
`As set forth in WestemGeco's Opening Brief, the Bittleston patents teach a variety of
`
`distributions of streamer array control, including between a global control system and local
`
`control systems. (WGOB at 12-13) WestemGeco's proposed construction of a "global control
`
`system" is based on the term's ordinary meaning in this context. (!d) ION does not dispute this
`
`fact. (IRB at 7) WestemGeco's proposed construction is proper under Phillips.
`
`ION's proposed construction, however, improperly restricts the patent to preferred
`
`embodiments. See, e.g., WGOB at 13; Phillips, 415 F.3d at 1323. There is nothing in the
`
`ordinary meaning of "global control system" that limits the commands sent or the recipients of
`
`those commands. In fact, the Bittleston patents teach that the global control system can issue
`
`many types of commands, such as a desired force, a desired location, a desired displacement or a
`
`desired wing angle. (Ex. 1 at 5:54-58,5:63-67,6:11-14,6:17-21, Cl. 7) And while some claims
`
`explicitly recite "local control systems" as the recipients of these commands, other claims are
`
`broader. Compare Ex. 3 at Cis. 1, 15 with Ex. 1 at Cis. 7, 8; see also Praxair, Inc. v. ATML Inc.,
`
`543 F.3d 1306, 1326 (Fed. Cir. 2008) ("[T]he structure of the claims confirms that [a proposed
`
`restriction] was not intended to be a feature of the invention as a whole.").
`
`ION's proposed
`
`construction- even as "revised"- improperly limits the claims to preferred embodiments and
`
`excludes other embodiments. See WGOB at 12-13; Telejlex, 299 F.3d at 1324; Halliburton, 514
`
`F.3d at 1251 ; DSW, 537 F.3d at 1348; Verizon, 503 F.3d at 1305.
`
`In its Response, ION argues that:
`
`(1) a description of "the inventive control system"
`
`should be used to limit "a global control system"; and (2) ION's "revised" proposed construction
`
`6
`
`Ex. PGS 1020
`
`

`

`Case 4:09-cv-01827 Document 77 Filed in TXSD on 03/12/10 Page 11 of 24
`
`no longer excludes disclosed embodiments. (IRB at 6-7) Neither argument has merit.
`
`First, ION's purported reliance on a description of "the inventive control system" IS
`
`misplaced. (IRB at 6) Unlike the language at issue in Verizon and Honeywell, the language
`
`cited by ION merely discusses what "the inventive control system is based on," not what "the
`
`present invention is." See Verizon, 503 F.3d at 1308; Honeywell, 452 F.3d at 1318. In fact, the
`
`specification earlier teaches that this description is merely a preferred embodiment:
`
`In the preferred embodiment of the present invention, the control system for the
`birds 18 is distributed between a global control ... and a local control system ...
`
`(Ex. 1 at 3:36-40). The context of the specification confirms that the claims are not limited to the
`
`one embodiment ION cites. See Praxair, 543 F.3d at 1326 ("Although these statements appear
`

`
`Second, ION's "revised" proposed construction still improperly excludes disclosed
`
`embodiments. Verizon, 503 F.3d at 1305. This would be improper even if the specification had
`
`discussed "the present invention." Rambus, 318 F.3d at 1094-95; Colorquick, 2008 WL
`
`5771324, at *7 n.9; Plasmart Inc. v. Wince!! Int'l Inc., No. 05-10745, 2007 WL 3355509, at *8
`
`(S.D.N.Y. Nov. 8, 2007) ("I do not read Verizon to mean that, when presented with magic words
`
`such as 'present invention' or 'the invention herein,' district courts should disregard contrary
`
`indications in the language of the claims, as well as other language of the specifications.").
`
`Although ION argues that "'desired positioning information' would encompass both desired
`
`location and displacement," IRB at 7, the term "positioning information" is not used in the
`
`specification, lacks intrinsic support, and is of unclear scope. And even if ION were correct as to
`
`this argument, ION's proposed construction appears to still exclude disclosed embodiments
`
`where the global controller "calculat[es] a desired change in the wing orientation," Ex. 1 at Cl. 7,

`
`Ex. PGS 1020
`
`

`
`or where the global controller monitors the positions of birds, rather than the streamers, Ex. 1 at
`
`3:61-63. Therefore, ION's "revised" proposed construction remains improper.

`As set forth in WestemGeco's Opening Brief, the Bittleston patents teach local control
`
`systems "located within or near the birds." (WGOB at 14) These local control systems can
`
`interact with the global control system in a number of ways, adding flexibility to the overall
`
`control system- one of the strengths of the Bittleston patents. (!d. at 13-14) WestemGeco's
`
`proposed construction is consistent with the ordinary meaning of the term in light of this intrinsic
`
`evidence. ION does not dispute this fact. (IRB at 8)
`
`ION's proposed construction, however, is flawed for excluding disclosed embodiments
`
`such as local control systems "near the birds" (WGOB at 14; Ex. 1 at 3:36-40); for limiting the
`
`signals the local control systems can receive (WGOB at 13-14, § II(b), supra); and for excluding
`
`embodiments where the global controller "calculat[es] a desired change in the orientation of the
`
`wings." (WGOB at 14) ION fails to address these flaws in its Response. (IRB at 8)
`
`In its single paragraph, ION instead focuses on the statement regarding "the inventive
`
`control system," discussed above.
`
`(IRB at 8) As with the global control system, however:
`
`(1) this is not a description of "the present invention"; (2) this is not the "Summary of the
`
`Invention"; (3) this is merely a preferred embodiment, as explained by other portions of the
`
`specification; and (4) ION's proposed revised proposed construction still excludes the disclosed
`
`embodiments discussed above. ION's "revised" proposed construction is still properly rejected.

`As set forth in WestemGeco's Opening Brief, the Bittleston patents teach a variety of
`

`
`and accepts that WestemGeco's proposed construction is proper. (IRB at 8) However, ION
`
`requests "clarification" that this term does not include "force information." (IRB at 8-9) It is
`
`unclear that the intrinsic record draws a rigid line between location and force information or, in
`
`any event, how ION proposes to incorporate this distinction into the claim construction.

`
`streamer; and (2) devices in-line with the streamer. (WGOB at 6; WestemGeco Response Brief
`
`at 3 & n.2) WestemGeco's proposed construction is based on the ordinary meaning of the
`
`prepositions "on" and "in-line with" in this context. ION, in contrast, fails to provide any support
`
`for its "revised" proposed construction of "on" as "attached to." (IRB at 9)

`
`WestemGeco's proposed construction is consistent with this ordinary meaning. (IRB at 9-10)
`
`Even as "revised," however, ION's proposed construction still improperly reads a "global
`
`control system" into the claims. This renders superfluous separate language in some claims that
`
`the global control system implements the control mode. See, e.g., Ex. 1 at Cl. 7, Ex. 2 at Cl. 7;
`
`Stumbo, 508 F .3d at 1362. And it ignores the context of the claims for those claims that do not
`
`recite a global controller. See, e.g., Ex. 4 at Cis. 1, 2; Phillips, 415 F.3d at 1314-15. ION fails to
`
`address these facts in its Response. (IRB at 1 0) Notably, ION has deleted any requirement of a
`
`global control system in its "revised" proposed construction of "turn control mode." (IRB at 1 0)

`
`mode" is limited to what mode is selected after the turn is completed.
`
`Even as "revised," ION's proposed construction still improperly reads a "feather angle
`
`mode" into the end of a turn control mode. This renders language superfluous in those claims
`
`that recite a feather angle mode after completing the turn control mode. See, e.g., Ex. 4 at Cl. 6;
`
`Stumbo, 508 F.3d at 1362. It ignores the context of those claims that explicitly do not. See, e.g.,
`
`Ex. 4 at Cl. 9; Phillips, 415 F.3d at 1314-15. And it violates the doctrine of claim differentiation
`
`by conflating the scope of Claims 6 and 9 of the Bittleston '520 patent. See, e.g., WGOB at 17-
