`
`I.
`
`INTRODUCTION
`
`The Court should adopt NXP’s proposed constructions, which are grounded in the intrinsic
`
`record. AST’s proposed constructions impermissibly seek to ignore its own admissions to the
`
`patent office in an attempt to improperly broaden the asserted claims. AST’s approach should be
`
`rejected and the intrinsic record embraced by adoption of NXP’s constructions.1
`
`II.
`
`AST’S PROPOSED CONSTRUCTIONS ARE OVERBROAD AND IGNORE THE
`INTRINSIC RECORD
`A.
`
`Term 1: “A method for reducing power consumption for a video decoder
`comprising”
`
`AST paradoxically argues (a) that the preamble of claim 26 recites an intended benefit of
`
`the claim, yet (b) such intended benefit does not even apply to the claim. Specifically, AST argues
`
`that “reducing power consumption” is a “shorthand encapsulation of the advantages of the
`
`invention.” Resp. (Dkt. 50) at 6 (quoting Bristol-Myers Squibb Co. v. Immunex Corp., 86 F. Supp.
`
`2d 447, 451 (D.N.J. 2000)). But having conceded the importance of “reducing power
`
`consumption” to the claim, AST then seeks to impermissibly broaden the scope of the claim to
`
`include performance of the claimed method in a manner that does not actually reduce power
`
`consumption. Resp. at 6 (contending “the claimed methods and systems dynamically raise and
`
`lower consumption to achieve performance targets”), Hart Decl. (Dkt. 50-2), ¶ 14 (“I understand
`
`
`
`
`
`
`
`
`
`
`
`1 In support of AST’s plain and ordinary meaning constructions, both AST’s Response and the
`corresponding expert declaration of Dr. John C. Hart repeatedly reference how a supposed
`POSITA would understand certain claim terms. But, critically, neither the response nor
`declaration provide any explanation about who the POSITA is, and what knowledge and
`experience he/she brings to the table. Multiform Desiccants, Inc. v. Medzam, Ltd., 133 F.3d 1473,
`1477 (Fed. Cir. 1998) (noting that claims are construed through the eyes of a POSITA, who is
`“deemed to read the words used in the patent documents with an understanding of their meaning
`in the field, and to have knowledge of any special meaning and usage in the field”). As AST has
`not defined the skills necessary to qualify as a POSITA with respect to the asserted patents, it has
`failed to demonstrate the relevance of such opinions. Therefore, any statements in the Response
`or declaration regarding the understanding of a POSITA should be disregarded. However, even
`considering Dr. Hart’s declaration and AST’s statements regarding a POSITA, NXP’s proposed
`constructions should still be adopted as detailed below.

`
`that NXP contends that claim 26 of the ‘435 Patent requires that the power consumption of the
`
`video decoder decrease because the preamble refers to a method for reducing power
`
`consumption. I disagree.”).2 As such, AST’s primary purpose for arguing the preamble of claim
`
`26 is not limiting is to impermissibly broaden the claim to capture activity not contemplated by
`
`the claim at all—i.e., activities that would increase power consumption.
`
`In doing so, AST conveniently ignores a basis for finding a preamble limiting is “when the
`
`preamble is essential to understand limitations or terms in the claim body.” Catalina Mktg. Int’l,
`
`Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002). AST agrees that claim 26 recites
`
`the steps described in Figure 9 of the ’435 patent. Resp. at 5–6. Here, if a practitioner followed
`
`the exact steps recited in Figure 9 and that resulted in increasing “the power consumption for a
`
`video decoder,” then under AST’s interpretation that practitioner would still infringe claim 26.
`
`This alone makes the preamble the very definition of a term that is “essential to understand” the
`
`claim body because the claim is on its face limited to a method for “reducing,” rather than
`
`increasing, “power consumption.”
`
`Further, AST’s reliance on Bristol-Myers Squibb is misplaced. Resp. at 6. In finding a
`
`preamble non-limiting, the Bristol-Myers Squibb Court noted that “to achieve the beneficial results
`
`promised in the preamble, a practitioner need only follow the method steps recited in the body of
`
`the claim.” Bristol-Myers Squibb, 86 F. Supp. 2d at 451. That is not the case here. As admitted
`
`by the ’435 patent itself, a practitioner could “follow the method steps recited in the body of” claim
`
`26 and increase the power consumption for a video decoder, whereas the promised beneficial
`
`result is decreased consumption.
`
`Last, AST argues that finding the preamble limiting would create confusion about claim
`
`
`
`
`
`
`
`
`2 All emphasis added unless otherwise noted.

`
`scope. Resp. at 7. AST chose to draft and then assert claim 26. It cannot now run from the
`
`language it chose by claiming it is confusing after the fact, nor can it attempt to broaden the claim
`
`to include situations where the method steps result in an increase in power consumption for the
`
`video decoder. AST’s series of rhetorical questions on page 7 of its Response3 confirms AST’s
`
`true purpose is to broaden the scope of claim 26, underscoring the need to find claim 26’s preamble
`
`limiting.
`
`B.
`
`Term 2: “graphics pipeline”
`
`AST fails to identify any intrinsic evidence to support its argument that the claimed
`
`graphics pipeline is not limited to “hardware, which may be one or more circuits.” First, with no
`
`support in the intrinsic record, AST argues that a POSITA would understand that the claimed a
`
`“memory controller could, and often does, implement software instructions.” Resp. at 8. The fact
`
`that a memory controller could do anything has no
`
`bearing on what is actually disclosed in the
`
`specification for the separate graphics pipeline.
`
`AST then distorts its only reference to the
`
`specification, conflating the host [red] with the
`
`separately disclosed graphics pipelines [blue].
`
`Specifically, AST incorrectly contends that “the
`
`graphics processing circuit 34 (which includes
`
`graphics pipelines 101 and 102) may be integrated
`
`
`
`
`
`
`
`
`
`
`
`3 AST’s rhetorical questions include: “If the claim requires ‘reducing power consumption,’ as NXP
`proposes, must ‘varying’ then only mean ‘reducing’? Must power consumption be reduced based
`on the input stream encoding description data more than it is increased by the receipt of more than
`one input stream? Does the power consumption of the video decoder have to decrease, even if
`the power consumption of the operational portion of the device increases?” Resp. at 7.
`
`
`
`- 3 -

`

`

`Case 6:22-cv-00466-ADA-DTG Document 56 Filed 01/09/23 Page 8 of 14
`
`with a host processor, which in turn may be a ‘graphics application running on the system
`
`processor.’” Resp. at 8 (citing ’945 patent at 3:61–67) (emphasis in original). AST’s cited portion
`
`of the specification actually states that “the host” [red] that provides data 31 to circuit 34 “may be
`
`a system processor (not shown) or a graphics application running on the system processor.” ’945
`
`patent at 3:65–67. Nowhere does the specification describe the separate graphics pipelines 101
`
`and 102 as an “application.”
`
`AST’s contention that references cited by the examiner during prosecution disclosed
`
`graphics pipelines that include software—inferring that an examiner would understand the ’945
`
`patent to have the same disclosure—is similarly non-sensical and not relevant. The fact that
`
`different references disclose a graphics pipeline that includes aspects of both software and
`
`hardware does not change that here, in AST’s actual asserted patent, the applicant chose to embody
`
`the claimed graphics pipeline as a collection of one or more “circuits” on a “chip;” cited prior art
`
`cannot change that the ’945 patent consistently describes the graphics pipeline as hardware. See
`
`’945 patent, 1:21–23, 4:5–9, 4:16–17; FIG. 2; claims 1, 4, 11, 21.
`
`Because the specification and claims of the ’945 Patent specifically describe the “graphics
`
`pipeline” as a “circuit” composed of “circuitry,” the proper construction of this term in view of the
`
`intrinsic and extrinsic evidence is “hardware, which may be one or more circuits.”4
`
`C.
`
`Term 3: “graphics pipelines operative to process data in a dedicated tile”
`
`As best understood, AST argues, without citation to the specification, that the ’945 Patent
`
`discloses that a particular pipeline processes “pixel data 36 for a primitive that is not within a
`
`single tile . . . to identify the pixels for which pixel attribute operations are performed.” Resp. at
`
`10. AST ignores that such an approach directly conflicts with claim language requiring “a
`
`
`
`
`
`
`
`
`
`
`
`4 To focus the parties’ dispute, NXP agrees to drop “that processes graphics data” from its proposed
`construction.
`
`
`
`- 4 -
`
`

`

`Case 6:22-cv-00466-ADA-DTG Document 56 Filed 01/09/23 Page 9 of 14
`
`respective one of the at least two graphics pipelines operative to process data in a dedicated tile.”
`
`If, as AST contends, each pipeline processes data that is not within its dedicated tiles, this claim
`
`language is rendered meaningless, and AST’s own IPR argument distinguishing prior art is
`
`misleading. NXP’s proposed construction is consistent with and appropriately clarifies that the
`
`“dedicated tile” is processed by one and only one pipeline—an understanding connoted by the
`
`term “dedicated” and confirmed in AST’s explanation to the PTAB.
`
`AST does not dispute that the ’945 Patent discloses that “the first graphics pipeline 101 [is]
`
`operative to process graphics data in a first set of tiles,” and the “second graphics pipeline 102 [is]
`
`operative to process graphics data in a second set of tiles.” Resp. at 10–11; ’945 Patent at 4:5–13,
`
`FIGS. 2–3. Nor does AST dispute that it distinguished prior art in the IPR proceedings based on
`
`a particular pipeline/processor processing pixels “whether they are in the tile or not” and “not
`
`within the tiles assigned to that processor.” Resp. at 11–12. There appears to be no distinction
`
`between the argument AST is now advancing and the disclosures in the prior art references it
`
`previously distinguished.
`
`Accordingly, AST’s proposal of plain and ordinary meaning for the term “graphics
`
`pipelines operative to process data in a dedicated tile” is a belated attempt to distance itself from
`
`its prior arguments and to broaden the term for infringement purposes.
`
`D.
`
`Term 4: “a memory controller . . . operative to transfer pixel data between
`each of a first pipeline and a second pipeline [the two graphics pipelines] and
`a memory shared among the at least two graphics pipelines”
`
`Rather than addressing the ambiguity in the actual claim phrase at issue, AST argues that
`
`this “term employs the common and well understood formulation of ‘between each of X or Y and
`
`Z.’” Resp. at 12. Such a “formulation” might be helpful if that is what the claim actually recited.
`
`It is not. The claim does not include “or” but instead recites “between each of a first pipeline and
`
`a second pipeline and a memory.” AST cannot rewrite the claim because the plain words are now
`
`
`
`- 5 -
`
`

`

`Case 6:22-cv-00466-ADA-DTG Document 56 Filed 01/09/23 Page 10 of 14
`
`inconvenient.
`
`In direct contravention to its multiple arguments in IPR proceedings detailed in NXP’s
`
`Opening Brief, AST now states that “the claim language does not require any transfer of pixel data
`
`between pipelines.” Resp. at 12 (emphasis in original). Specifically, in the VW POPR, AST stated
`
`that “the memory controller does not just transmit data to the shared graphics memory 48, but also
`
`to, from, and between the pipelines 101 and 102. . . . This interaction with and between the first
`
`and second pipelines is confirmed by the only passage that Volkswagen quotes in support of its
`
`claim construction.” Ex. 2 at 21. AST further argued over prior art that “Gove does not describe
`
`. . . transferring pixel data between one parallel processor and another . . .” Id. at 32–33; see
`
`also id. at 34 (“[I]t does not transfer data from one pipeline to another.”). In the Unified Patents
`
`POPR, AST asserted “that the memory controller be operative between the shared memory and
`
`between the first and second pipelines.” Ex. 1 at 22; see also id. at 23 (“[T]he memory controller
`
`does not just transmit data to the shared graphics memory 48, but also to, from, and between the
`
`pipelines 101 and 102.”). Distinguishing prior art, AST reiterated this understanding: “But Seiler
`
`does not describe the ‘memory interface 210’ as transferring pixel data (or any data) between
`
`one pipeline and another pipeline.” Id. at 26–27.
`
`Moreover, in its Preliminary Infringement Contentions, AST confirms that this term
`
`requires transfer “between pipelines”:
`
`Ex. 9 at 14.
`
`AST argues that the requirement to “transfer pixel data between the first and second
`
`pipeline . . . would make no sense to a POSITA.” Resp. at 13. This argument is again belied by
`
`AST’s IPR filings and its own expert. In the Unified POPR, AST’s expert, Dr. Hart explained that
`
`
`
`
`
`- 6 -
`
`

`

`Case 6:22-cv-00466-ADA-DTG Document 56 Filed 01/09/23 Page 11 of 14
`
`a POSITA would understand that “the claimed memory controller is operative to transfer data
`
`between the pipelines and from the pipelines to the shared memory.” Ex. 10 at ¶ 22. And Dr.
`
`Hart distinguished prior art based on this very construction, explaining that: “Seiler does not
`
`describe memory interface 210 [the prior art memory interface] as transferring processed pixel
`
`data (or any data) from one pipeline to another. . . . Figure 2 and the Seiler reference does not
`
`describe or depict memory interface 210 as transferring data from one pipeline to another.” Id.
`
`at ¶ 25.
`
`Despite its prior IPR arguments, AST now contends that the specification does not support
`
`NXP’s construction (Resp. at 14–16 (citing ’945 Patent at 5:4–7, 5:33–36, 4:16–22)). Again, this
`
`argument is the exact opposite of its representations in the IPR proceedings citing the very same
`
`portions of the specification:
`
`As illustrated in Fig. 2 (reproduced below), the specification describes pipeline 101
`including back end circuitry 39 and pipeline 102 as including back end circuitry 42.
`(’945 Patent at 4:5-15, 4:66 – 5:7, 5:28-36.) The specification further describes (and
`Fig. 2 further illustrates) that the memory controller does not just transmit data to
`the shared graphics memory 48, but also to, from, and between the pipelines 101
`and 102. (E.g., ’945 Patent at Fig. 2, 5:37-40.)
`
`Ex. 1 at 23.5
`
`Fundamentally, rather than address its representations in the multiple IPR proceedings
`
`regarding necessary clarification based on a POSITA’s understanding of the scope of this term,
`
`AST ignores the IPRs entirely and argues that “the IPR statements do not matter.”6 Resp. at 17.
`
`AST is wrong. AST’s statements to the PTAB during the IPR proceedings constitute part of the
`
`
`
`
`
`
`
`
`
`
`
`5 AST also conflates distinct requirements under 35 U.S.C. § 112 by arguing that inclusion of this
`term as lacking written description support in NXP’s Preliminary Invalidity Contentions but not
`arguing this term is indefinite during claim construction precludes adopting NXP’s proposed
`construction. Resp. at 15. As the Court is aware, written description and indefiniteness are two
`separate bases for invalidity under 35 U.S.C. § 112, and an allegation that a term is lacking written
`description is not waived by not raising it during claim construction.
`6 This despite relying on its IPR filings in support of its arguments for Term 3.

`
`2017 WL 6375173, at *5 (D. Del. Dec. 13, 2017) (patent owner statements during IPR constitute
`
`prosecution history disclaimer).7 Accordingly, AST’s attempt to disregard its prior arguments is
`
`contrary to law and an impermissible attempt to rewrite this term. “A patentee may not proffer
`
`an interpretation for the purposes of litigation that would alter the indisputable public record
`
`consisting of the claims, specification and the prosecution history, and treat the claims as a ‘nose
`
`of wax.’” Southwall Techs. Inc. v. Cardinal IG Co., 54 F.3d 1570, 1578 (Fed. Cir. 1995) (quotation
`
`omitted).8
`
`E.
`
`Term 5: “NxM number of pixels”
`
`As detailed in NXP’s Opening brief and undisputed by AST, during prosecution, AST
`
`distinguished “NxM number of pixels” over prior art by arguing that this term refers only to “non-
`
`square” blocks of pixels in contrast to a prior art reference, Kelleher, that taught “each block is
`
`square.” Resp. at 18; Opening at 13–14. AST now argues that, after the examiner entered a
`
`subsequent rejection based on a new prior art reference, Perego, “Applicants recognized their

`Signal IP, Inc. v. Fiat U.S.A., Inc., No. 14-cv-13864, 2016 WL 5027595, at *16 (E.D. Mich. Sept.
`20, 2016) (same).
`8 Separately, AST argues without support that had it wanted to indicate NXP’s proposed
`construction , it would have used “among” instead of “between” in the claims. Resp. at 13–14.
`This ignores the common usage of these terms. Indeed, the Chicago Manual of Style indicates that
`“between indicates one-to-one relationships” including relationships of more than two things. Ex.
`11 at 314–15. In contrast, “among” indicates a “undefined or collective relationships.” Id. at 315.
`Thus, the use of “between” followed by the recitation of three items indicates a one-to-one
`relationships between the three items, consistent with NXP’s proposed construction.

`
`mistake and never again argued that NxM excluded square blocks.” Resp. at 18. AST fails to
`
`mention (or realize) that it could not make this argument again because, as the examiner pointed
`
`out, “Perego teaches that each region is rectangular.” Ex. 8 at 3 (Office Action (Aug. 28, 2007))
`
`(AST0000700–12). Thus, rather than recognize a mistake, the argument was simply inapplicable.
`
`Indeed, AST’s filings in the later ITC Action confirm its continued understanding that “NxM
`
`number of pixels” refers to a non-square arrangement—AST agreed the proper construction was
`
`“plain and ordinary meaning, for example: a rectangular, but not square, array of pixels denoted
`
`by N number of row and M number of columns.” Ex. 12, AST’s Reply Claim Construction Brief
`
`at 49–50.
`
`Regardless, Ecolab does not support AST’s “acquiescence by the applicant” argument.
`
`Resp. at 19 (citing Ecolab, Inc. v. FMC Corp., 569 F.3d 1335 (Fed. Cir. 2009)). In Ecolab, the
`
`applicant argued that two prior art references did not disclose certain claim elements. 569 F.3d at
`
`1343. After the examiner clarified the scope of the claims and maintained the rejection on the
`
`same two prior art references, applicant made additional distinguishing arguments. Id. The
`
`applicant in Ecolab clearly agreed with the examiner and advanced different arguments against the
`
`same prior art refences. That is not the case here where the examiner entered a new rejection based
`
`on a different prior art reference that disclosed rectangular blocks of pixels.
`
`Because NXP’s construction reflects the intrinsic record and AST’s own prior art
`
`distinctions, NXP’s proposal of a “rectangular block of pixels that is not square” should be
`
`adopted.
`
`III. CONCLUSION
`
`For the foregoing reasons, NXP respectfully requests the Court adopt its constructions.
