      “of the ’758 patent supports an understanding that some activity is required for a polypeptide to be a “modified PH20 polypeptide,” and it is the enzymatic activity of hyaluronidase specifically that is the most frequently identified activity recited in the Definitions section of the ’758 patent. Indeed, both the definitions of “PH20” and “modified PH20 polypeptide” require hyaluronidase activity. See Ex. 1001, 45:54–55, 50:39–41 (“PH20 refers to a type of hyaluronidase that . . . is neutral-active” and “neutral active refers to the ability . . . to enzymatically catalyze the cleavage of hyaluronic acid at neutral pH”); 48:43–46 (“A modified PH20 polypeptide can have up to 150 amino acid replacements so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.”). Similar language is used later in the definition of a “conjugate” to explain that even when the modified PH20 polypeptide is linked to another polypeptide or chemical moiety it “retains hyaluronidase activity.” Id. at 63:39–46. In contrast, the discussion regarding the potential use of “modified PH20 polypeptides that are inactive” as antigens in contraception vaccines appears only in non-definitional sections of the ’758 patent. Id. at 72:63–65, 75:60–62. Accordingly, we find that this disclosure does not modify the definition’s explicit requirement that the claimed “modified PH20 polypeptide” exhibit hyaluronidase activity.

      “4. Analysis Based on the evidence of record, we agree with Patent Owner that Petitioner has not provided any persuasive reason to particularly target the leucine at position 307 of a PH20 polypeptide for modification as recited in claim 1 of the ’590 patent. It is undisputed that neither of the cited prior art references, the ’429 patent or Chao, specifically identifies or discusses position 307 of the PH20 polypeptide. See, e.g., Pet. 88‒109; PO Resp. 86‒ 93. We are not persuaded by Petitioner’s argument that multiple sequence alignments identify amino acids that are tolerated at particular positions (see Pet. 99‒109), because tolerance is not a positive reason to make a substitution. “It is not enough, even after KSR, to support a determination of obviousness that a reference includes a broad generic disclosure and a common utility to that in the claims and other prior art references—there must be some reason to select a species from the genus.” Knauf Insulation, Inc. v. Rockwool Int’l A/S, 788 F. App’x 728, 733 (Fed. Cir. 2019). Dr. Park identified 379 positions in PH20 (i.e., ~85% of the protein) with evolutionary variation, that is, where “homologous proteins have tolerated different amino acids at those positions.” Ex. 1004 ¶ 31. Dr. Park distributes the twenty standard amino acids into four categories depending on their roles in forming secondary structure such as alpha helices or beta sheets, with each category having a minimum of six members. See id. ¶ 70. Nothing in the prior art or Dr. Park’s analysis directs the ordinary artisan to position 307 itself. Although Dr. Hecht asserts that the ’429 patent suggests conservative mutations generally, Petitioner did not point us to any specific teaching or” slip op. at 126

That is, it may have been obvious to a POSA to align PH20 sequences with other known hyaluronidase enzymes and to use the crystal structure of a different hyaluronidase (Hyal-1) in SWISS-MODEL to generate a three-dimensional structure, but none of that is described in the common disclosure itself. “[A] description that merely renders the invention obvious does not satisfy the [written description] requirement.” Ariad, 598 F.3d at 1352. While a POSA might be able to embark on their own research program to try to find suitable multiply-modified PH20 polypeptides, the four corners of the written description do not demonstrate possession of such.

      “exclude the use of modified PH20 polypeptides as contraceptives—the only other possible utility described in the ’652 patent—is unavailing. Resp. 39. First, “[t]he fact that a patent asserts that an invention achieves several objectives does not require that each of the claims be construed as limited to structures that are capable of achieving all of the objectives.” Phillips, 415 F.3d at 1327 (citing Liebel–Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 908 (Fed. Cir. 2004)). Second, unlike the definitions of “PH20” and “modified PH20 polypeptide” in the “Definitions” section of the Specification, the passages describing possible contraceptive use do not contain any characteristics suggesting they are definitional in nature. See Alnylam, 138 F.4th at 133 (enumerating “characteristics” such as the fact that the text appears in the “Definitions” section, sets the term off in quotation marks, and uses phrases like “refer to” that indicate that specification language is definitional in nature). Accordingly, the statement that “[a]lso provided are modified PH20 polypeptides that are inactive, and that can be used, for example, as antigens in contraception vaccines” (Ex. 1001, 75:56–58), does not redefine the term, nor otherwise void the definitional language in the Specification stating that a “modified PH20 polypeptide can have up to 150 amino acid replacements, so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Id. at 48:47–49 (emphasis added).” slip op. at 26

      “We decline Patent Owner’s invitation to construe “during a frame” of “independently controlling simultaneous data acquisition with each of the first and second channels during a frame” by importing the extraneous limitations “at some point between the beginning and the end of the exposure interval during which the image sensors capture a single image.” As pointed out by Petitioner, Patent Owner’s proposed construction is unsupported by the language of claim 22 and the ’180 Specification because Specification does not disclose an exposure interval nor suggest “during a frame” is limited to an exposure interval. Patent Owner and its expert Dr. Saber cite only extrinsic evidence (Exs. 2006, 2009) to support its argument that claim 22 should be limited to an “exposure interval during which the image sensors capture a single image.” See PO Resp. 16–17; Ex. 2020 ¶ 64. Similarly, Patent Owner relies only on extrinsic evidence (e.g., Ex. 2011, 1; Ex. 2022, 1; Ex. 2020 ¶ 66) to limit “during” to “at some point between the beginning and the end.” See id. at 18. When considered in the context of claim 22 and the ’180 Patent Specification which do not limit “during a frame” to an exposure interval, we find that we cannot rely on Patent Owner’s citations to extrinsic evidence to yield a reliable construction for “during a frame.” As demonstrated in the analysis below, we need not provide an explicit construction for “during a frame” to resolve the parties’ disputes regarding the merits of the patentability challenges. See Realtime, 912 F.3d at 1375. We apply the ordinary and customary meaning for “during a frame.” To the extent that an explicit identification of the ordinary and customary meaning may aid the understanding of our analysis, consistent with the language of claim 22 and the ’180 Patent Specification, we find that the ordinary and customary meaning for “during a frame” is “during the period of time that data for an image frame is acquired.” See Ex. 1001, code (57), 20:6–24, 25:23–35.” slip op. at 12

Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010).

See PO Resp. 60–64; PO Sur-reply 25–28. Specifically, Patent Owner does not address written description support in the ’854 Provisional Application for “independently controlling simultaneous data acquisition with each of the first and second channels during a frame”––limitation [22.3]––the heart of the parties’ claim construction disputes addressed above in Section II.A. See PO Resp. 60–64; PO Sur-reply 25–27. Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in the ’854 Provisional Application.

      “We do not agree with Petitioner’s arguments based on retrieval of data from CCD 18A and CCD 18B. Although Matsushima’s CCD drive circuits 20A and 20B are driven synchronously by timing generator 28 (see Ex. 1007 ¶ 27), Matsushima discloses that “accumulated signal charges are retrieved by CCD drive pulses applied by CCD drive circuits 20A and 20B, and are sequentially output from CCD 18A and CCD 18B as voltage signals (analog image signals) corresponding to each signal charge” (see Ex. 1007 ¶ 23) (emphasis added). In other words, regardless of whether CCD drive circuits 20A and 20B are driven synchronously by timing generator 28, Matsushima discloses that voltage signals corresponding to the accumulated 8 Petitioner’s citation erroneously includes ¶¶ 34–36 of Exhibit 1069.

In the Reply for the first time, Petitioner asserts that “a POSITA would understand that Matsushima’s disclosure, including its multi-channel architecture, synchronous control of channels, and capturing two images that are scaled versions of the same scene, renders obvious simultaneous acquisition during a frame. Pet. Reply 13 (citing Ex. 1069 ¶ 49). We do not consider Petitioner’s belated argument because it exceeds the proper scope of a reply. A reply may only respond to arguments raised in the corresponding patent owner response. See 37 C.F.R. § 42.23. As explained in the Trial Practice Guide, “respond” “does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing.” Trial Practice Guide at II.I.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “We agree that Patent Owner’s proposed claim construction is wholly unsupported by, and inconsistent with, the language of independent claims 1, 7, and 13, and the aims of the ’670 Patent Specification. See Ex. 1001, 2:3– 25, 9:32–10:5, 12:51–67, 18:54–19:6, 19:26–42, 20:12–26. Moreover, the cited extrinsic evidence––testimony by Patent Owner’s expert Dr. Lomp–– does not support Patent Owner’s proposed construction because it is internally inconsistent and also undermined by Dr. Lomp’s inconsistent deposition testimony. See Ex. 1036, 11:6–17, 12:9–12; Ex. 2010 ¶¶ 40, 48. Similarly, the extrinsic evidence cited by Petitioner (e.g., Exs. 1037, 1038, 2009) undermines Patent Owner’s position emphasizing the intended recipient devices of SIB1. In summary, we decline to adopt Patent Owner’s proposed claim construction because it is unsupported by the claim language, the ’670 Patent Specification, and the cited extrinsic evidence. with the ordinary and customary meaning which does not include limiting SIB1 to an ordinary legacy SIB and excluding MTC specific SIBs or SIBs intended for MTC devices. In addition, we need not construe explicitly any other claim term or phrase. See, e.g., Nidec Motor Corp. 868 F.3d at 1017 (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v.

Patent Owner does not dispute Petitioner’s definition. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s definition of a person of ordinary skill in the art because it is consistent with the level of skill reflected by the ’670 Patent Specification and the prior art of record. slip op. at 14

      “filing date. As explained above, the burden of production shifted to Patent Owner to show that Wallen is not prior art because the ’670 Patent is entitled to the earlier January 20, 2012, filing date of foreign priority application GB1201000. See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Patent Owner’s arguments fail to meet this burden of production because, aside from addressing a system information block 1, Patent Owner’s arguments do not substantively address how GB1201000 provides written description support for any other limitations of the claimed invention. See PO Resp. 43, 57. Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in foreign priority application GB1201000, the burden of production did not shift back to Petitioner, and,” slip op. at 18

      “primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB).” See Pet. 41–42 (citing Ex. 1003 ¶¶ 70–75; Ex. 1005 ¶¶ 76, 77, 83–84). Petitioner implicitly acknowledges that Wallen does not expressly disclose a physical broadcast channel (PBCH), but relies on Berggren for confirming that the LTE standard specifies that a PBCH carries the MIB. See Pet. 42–43 (citing Ex. 1003 ¶ 74; Ex. 1007 ¶¶ 73–75). According to Petitioner, “a person of ordinary skill in the art would have been motivated to transmit Wallen’s MIB using a PBCH as taught by Berggren.” Pet. 43 (citing Pet. 33–38). In particular, Petitioner asserts that a person of ordinary skill in the art “would have been motivated for Wallen’s LTE system to utilize the LTE standard implementation details taught by Berggren,” and “it would have been predictable and beneficial for Wallen’s user equipment to receive the MIB in the [PBCH], as was standard in LTE.” Pet. 34 (citing Ex. 1003 ¶ 58), 37 (citing Ex. 1003 ¶ 63). According to Petitioner, “the combination is nothing more than ‘the predictable use of prior art elements according to their established functions.’” Pet. 38 (citing KSR, 550 U.S. at 417). Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Wallen’s broadcast MIB with Berggren’s teachings of using a PBCH for transmitting broadcast MIBs.

      “Petitioner argues that a person of ordinary skill in the art would have been motivated to look to the features of both Singh129 and Singh906 when considering an improved publishing system. Pet. 16. Further, Petitioner points out that Singh129 incorporates by reference the ’802 application, published as Singh906. Id. According to Petitioner, a person of ordinary skill in the art would have been motivated to modify Singh129’s system to add Singh906’s user authentication credentials to Singh129’s user preferences to give the “user more control over the publishing of their multimedia content.” Id. at 17 (citing Ex. 1030 ¶ 456). Petitioner cites four additional reasons for a person of ordinary skill in the art to modify Singh129 with Singh906 including solving a known problem, avoiding sending authentication credentials to publish content, virtual spaces provided for clients in Singh906, and that authentication credentials would have been an obvious design choice. Id. at 17–18 (citing Ex. 1009 ¶ 47, Figs. 2, 5; Ex. 1010 ¶¶ 17, 18, 27; Ex. 1030 ¶¶ 457–461). Petitioner also asserts a person of ordinary skill in the art would have had a reasonable expectation of success for the modification of Singh129 with Singh906. Pet. 18. Petitioner argues “the proposed combination would have required no more than the application of known techniques (using authentication credentials and HTTP in accordance with Singh906) to a known system (Singh129’s system) in the same field of endeavor (media publishing) and from the same assignee (CellSpinSoft) to obtain the benefits described above.” Id. (citing Ex. 1030 ¶ 461). Based on the record before us, we find sufficient the argument and evidence that the combination of Singh129 and Singh906 teaches or suggests all of the limitations of claim 1, and that a person of ordinary skill in the art would have had reason to combine features from Singh906 into Singh129 with a reasonable expectation of success, for the reasons discussed in the Petition. See Pet. 16–19. We have also reviewed Petitioner’s contentions with respect to dependent claims 2–15, and find the same for these claims. See id. at 28–38.” slip op. at 25
