“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.

“Based on the record before us, Patent Owner has the better position. It is well settled that the original drawings may themselves be sufficient to provide description for later-filed claims. Vas-Cath, 935 F.2d at 1565 (holding that “drawings alone may provide a ‘written description’ of an invention as required by § 112”). That is the case here with respect to the original figures submitted with the Great-Grandparent application. We agree with Patent Owner and Dr. Garris that original Figures 4A–B and 5B show a flange or “radially protruding structure” configured as in the challenged claims. Ex. 2001 ¶¶ 106–113. Moreover, the original description in the Great-Grandparent application describes “removable retaining pins 13” that “ensure the recycling container,” i.e., container 12 in Figures 4A–B, “does not detach from the air-water separation tank 5 when there is no vacuum in the system.” Ex. 1002, 213 (¶ 92). Based on this description and the depiction of retaining pin 13 in the original Figure 2, a POSA would have understood that the pins engage with the radially protruding structure to hold the container in place as recited in the challenged claims. Ex. 2001 ¶ 114. Petitioner’s argument that the original figures do not depict the radially protruding structure and retaining pins working together to hold the container in place is unpersuasive. Patent Owner has sufficiently demonstrated that a POSA would have understood how the structures in original Figures 2 and 4A interact based on a side-by-side comparison of the same. See Pet. 38–43; Ex. 2001 ¶ 114. Indeed, the applicants made a similar comparison during prosecution, which proved persuasive to the Examiner. Ex. 1002, 87, 98. The Petition provides no reason to doubt that a POSA would understand the original figures and description just as Patent Owner contends. Moreover, contrary to Petitioner’s arguments, the fact that the specification and drawings were amended does not mean that Patent Owner had to add new matter to overcome the Examiner’s rejections. See Pet. 16– 17. In this case, the amendments to the specification during prosecution of the ’175 patent made the operation of the retaining pin and radially protruding structure, as shown by the original figures, even clearer. But that does not mean that the original description was inadequate.” slip op. at 18

“Institution of post-grant review is authorized by statute only when “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324; see 37 C.F.R. § 42.4.

- Skill levelSkill level petitioner adoptedDecided for petitioner
“The major differences between Petitioner’s and Patent Owner’s definitions of a skilled artisan include the number of years of drug discovery experience that is necessary and the breadth of the fields of endeavor with which a POSA should be familiar. We agree with Patent Owner that a POSA includes a team of skilled artisans with skill sets in the various aspects of drug development, but determine that Petitioner has addressed those necessary skill sets in its definition. We also determine on this record that Petitioner has assessed adequately the level of experience needed, and do not agree with Patent Owner that greater years of experience are necessary for a POSA in this instance. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (“A person of ordinary skill in the art is also a person of ordinary creativity, not an automaton.”). Because Petitioner’s definition of a person of skill in the art appears commensurate with the level of skill reflected in the asserted art in this case as well as the ’361 patent itself, we apply Petitioner’s proposed level of ordinary skill in the art to determine whether it is more likely than not that Petitioner would prevail on its challenges to claim 1. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (stating prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 10

“C. Claim Construction We construe claims “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b).” 37 C.F.R. § 42.200. Therefore, we construe the challenged claims under the framework set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc). Under this framework, 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, in light of the language of the claims, the specification, and the prosecution history of record. Id. Only those terms that are in controversy need be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Both parties agree that we need not construe any claim terms here to resolve the issues in this proceeding. See Pet. 16; Prelim. Resp. 18–19. We agree with the parties that we need not construe any claim terms in this proceeding to resolve whether to institute a post-grant review.” slip op. at 11

“In applying the rubric set forth in Ariad to determine whether claim 1 has appropriate written description support, we can look for structural features common to the members of the subgenus of claim 1 so that one of skill in the art can “visualize or recognize” the members of the subgenus. See Ariad, 598 F.3d at 1350. To do this, we look “for blaze marks within the disclosure that guide attention to the claimed species or subgenus.” See Regents of the Univ. of Minn., 61 F.4th at 1356. In this regard, the fourteenth aspect of the third embodiment is the blaze mark that points to the subgenus of claim 1. We do not need to find blaze marks that identify the fourteenth aspect of the third embodiment as the only formula of merit or the only one that should be claimed. Rather, we look to the written description to see if it describes sufficient structural features common to the members of the subgenus of claim 1 such that a POSA can visualize or recognize the members of that subgenus, thereby demonstrating that the inventors possessed the subject matter of the claim at the time they filed their application.” slip op. at 20

“We review the Petition under 35 U.S.C. § 324, which provides that a post-grant review may not be instituted unless “it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a). For the reasons provided below, we determine Petitioner has satisfied the threshold requirement set forth in 35 U.S.C. § 324(a). Accordingly, we institute a post-grant review of all challenged claims based on all grounds raised in the Petition. See SAS Inst., Inc. v. Iancu, 138 S.

“We disagree. It is unclear which aspect of the Petition that Patent Owner takes issue with. If it is the “multitudinous grounds” presented in the Petition, Patent Owner points to no authority that permits us to deny institution merely because a petition presents numerous grounds. In any event, on the facts of this case, we do not view eight grounds asserted in the Petition to be excessive.6 To the extent Patent Owner urges that we should deny institution because Petitioner’s grounds are “futil[e],” we understand that to be an argument on the merits, and not related to our discretion. See Prelim. 6 The Petition presents five grounds. See generally Pet. We agree with Patent Owner, however, the ground based on Tobler, in fact, encompasses three grounds, and the ground based on De Oliveira, in fact, encompasses two grounds. See Prelim. Resp. 2. Resp. 45. As explained below, we find Petitioner has established that it is more likely than not that claims 1–10 of the ’727 patent are unpatentable over Tobler. See infra Section II.D.2. Because the grounds based on Tobler apply to all challenged claims,7 at least these grounds are not, as Patent Owner asserts, futile. Thus, we decline to exercise discretion to deny the Petition under § 324(a).” slip op. at 6

“review, we “may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.” Our § 325(d) analysis employs a two-prong framework: (1) whether the arguments presented in the petition are the same or substantially the same as those previously presented to the Office; and (2) if so, whether the petitioner has demonstrated a material error by the Office in its prior consideration of those arguments. Advanced Bionics, LLC v. 7 The cases Patent Owner cites do not support its argument on discretionary denial under § 324(a). See Prelim. Resp. 45–46. In those cases, the Board exercised discretion to deny institution because the petitions only met the threshold requirement for institution with regard to a small percentage of the challenged claims. See Chevron Oronite Co. LLC v. Infineum USA L.P., IPR2018-00923, Paper 9, 11 (PTAB Nov. 7, 2018) (stating “instituting a trial with respect to all twenty claims based on evidence and arguments directed to dependent claims 3 and 4 is not an efficient use of the Board’s time and resources”); Deeper, UAB v. Vexilar, Inc., IPR2018-01310, Paper 7, 2 (PTAB Jan. 24, 2019) (denying institution because the petitioner only “demonstrated a reasonable likelihood of prevailing with respect to only two of twenty-three challenged claims as to only one of four asserted grounds of unpatentability”). MED-EL Electromedizinishe Gerӓte GmbH, IPR2019-01469, Paper 6 (“Advanced Bionics”), 8 (PTAB Feb. 13, 2020) (precedential). The parties agree that, during prosecution, the relevant disclosure in Tobler was before the Examiner in U.S. Patent Application Publication 2010/0216640, which was cited in an Information Disclosure Statement (“IDS”). Pet. 12; Prelim. Resp. 46. In other words, the first prong of the Advanced Bionics analysis is satisfied. Thus, we must determine whether Petitioner has shown a material error by the Office.
