“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. Id. at 48:38–46.” slip op. at 21

“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.

“After considering the parties’ arguments and evidence, we determine that Petitioner’s showing for the printed circuit board of claim element 1[c], as summarized above, is sufficient for purposes of granting institution of a post-grant review. For purposes of institution, Petitioner’s contentions are adequately supported by Schröder, which describes inlay 12 as a “flexible carrier material, e.g. PET, Kapton, etc.” and a “carrier” for the antenna, chip module, and “at least one further electronic component,” as well as Schröder’s Figures 7 and 8, which depict inlay 12 between ring halves 16 and 18. Ex. 1007, 12:28–42, 12:48–52, 12:61–65, 13:23–25. We have considered Patent Owner’s argument that Schröder’s inlay 12 “is merely a substance for holding the coil in place, not a printed circuit board,” as well as Patent Owner’s argument contrasting Schröder’s description of inlay 12 with the express disclosure of “a circuit on a circuit board” elsewhere in the reference. Prelim. Resp. 29–30 (emphasis omitted; citing Ex. 1007, 8:57–59, 22:48–50; Ex. 20119).

“E. Level of Ordinary Skill in the Art At this stage of the proceeding, there is no dispute about the level of ordinary skill in the art. Based on the testimony of Petitioner’s declarant, we determine that a person of ordinary skill in the art (“POSITA”) would have had a four-year degree in electrical engineering, mechanical engineering, biomedical engineering, optical engineering, or related field of study, and two years of experience in academia or industry studying or developing physiological monitoring devices such as non-invasive biosensors. A POSITA would have been familiar with sensor system design and signal processing. A higher level of education or skill can substitute for less experience, and vice versa. Ex. 1002 ¶ 29.

“On the current record, Patent Owner’s claim construction arguments are unpersuasive for several reasons. First, in addition to reciting a “user identifier,” claim 1 separately recites “wherein said user identifier uniquely identifies a particular user of the web service.” Ex. 1001, 11:66–67. The fact that the surrounding claim language specifies that the “user identifier” must uniquely identify a user “strongly implies” that such a requirement is not required by the term itself. Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005) (en banc) (explaining that the context in which a claim term is used “can be highly instructive” and that the fact that “the claim in this case refers to ‘steel baffles’ . . . strongly implies that the term ‘baffles’ does not inherently mean objects made of steel”); Digital-Vending Servs. Int’l, LLC v. Univ. of Phoenix, Inc., 672 F.3d 1270, 1275 (Fed. Cir. 2012) (“the reference in some claims to a ‘registration server being further characterized in that it is free of content managed by the architecture’ strongly implies that the term ‘registration server,’ standing alone, does not inherently mean a server that is free of managed content”). Moreover, there is no need to construe “user identifier” to include a requirement that it identify uniquely a user of a web service, as in Patent Owner’s proposed construction, because that requirement is apparent from the surrounding claim language. Second, Patent Owner has not shown that the authentication requirement in its construction, i.e., that the user identifier be a “text string” that “contains sufficient information to authenticate a user of the web service,” is supported by the intrinsic record. Patent Owner’s authentication requirement is not apparent from the claim language, nor has Patent Owner attempted to show that a POSITA would have understood the ordinary meaning of “user identifier” to require such. The only intrinsic support Patent Owner cites are figures and related disclosure describing a preferred embodiment in the ’802 application.9 This disclosure uses different terms, e.g., “user preferences” and “login information,” which on this record Patent Owner has not sufficiently connected to the “user identifier” in claim 1. See Ex. 2009 ¶¶ 18, 23, 25–26. Even if that connection had been shown, the disclosure Patent Owner cites is permissive in nature, stating, e.g., that “user preferences may comprise authentication credentials,” and not that authentication credentials are required. Id. ¶ 23. Thus, on the current record, we decline Patent Owner’s invitation to import an authentication requirement into the claims through the construction of “user identifier.”” slip op. at 12

First, in addition to reciting a “user identifier,” claim 1 separately recites “wherein each user identifier uniquely identifies a particular user of the web service.” Ex. 1001, 12:10–13. The fact that the surrounding claim language specifies that the “user identifier” must uniquely identify a user “strongly implies” that such a requirement is not required by the term itself. Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005) (en banc) (explaining that the context in which a claim term is used “can be highly instructive” and that the fact that “the claim in this case refers to ‘steel baffles’ . . . strongly implies that the term ‘baffles’ does not inherently mean objects made of steel”); Digital-Vending Servs. Int’l, LLC v. Univ. of Phoenix, Inc., 672 F.3d 1270, 1275 (Fed. Cir. 2012) (“the reference in some claims to a ‘registration server being further characterized in that it is free of content managed by the architecture’ strongly implies that the term ‘registration server,’ standing alone, does not inherently mean a server that is free of managed content”). Moreover, there is no need to construe “user identifier” to include a requirement that it identify a user of a web service, as in Patent Owner’s proposed construction, because that requirement is apparent from the surrounding claim language. Second, Patent Owner has not shown that the authentication requirement in its construction, i.e., that the user identifier be a “text string” that “contains sufficient information to authenticate a user of the web service,” is supported by the intrinsic record. Patent Owner’s authentication requirement is not apparent from the claim language, nor has Patent Owner attempted to show that a POSITA would have understood the ordinary meaning of “user identifier” to require such. The only intrinsic support Patent Owner cites are figures and related disclosure describing a preferred embodiment in the ’802 application.10 This disclosure uses different terms, e.g., “user preferences” and “login information,” which on this record Patent Owner has not sufficiently connected to the “user identifier” in claim 1. See Ex. 2009 ¶¶ 18, 23, 25–26. Even if that connection had been shown, the disclosure Patent Owner cites is permissive in nature, stating, e.g., that “user preferences may comprise authentication credentials,” and not that authentication credentials are required. Id. ¶ 23. Thus, on the current record, we decline Patent Owner’s invitation to import an authentication requirement into the claims through the construction of “user identifier.”” slip op. at 12

“In view of Petitioner’s Sotera stipulation, we will not exercise discretion to deny institution under 35 U.S.C. § 314(a). The Director has issued guidance stating that, when such a stipulation is presented, the PTAB will not discretionarily deny institution in view of the parallel litigation. Ex. 1023,8 3. That guidance is unequivocal and dispositive of the Fintiv analysis here.” slip op. at 14

“Patent Owner’s argument for discretionary denial under § 316(b) is unavailing. The statute provides that “[i]n prescribing regulations under this section, the Director shall consider the effect of any such regulation on the economy, the integrity of the patent system, the efficient administration of the Office, and the ability of the Office to timely complete proceedings instituted under this chapter.” 35 U.S.C. § 316(b). However, Patent Owner identifies no regulation, rule, or Office guidance that supports its argument here. In the absence of such, we discern no discretion under § 316(b) to deny the Petition based on the policy considerations and concerns Patent Owner alleges.” slip op. at 16
- Skill levelSkill level petitioner adoptedDecided for petitioner
“A. Level of Ordinary Skill in the Art Petitioner alleges a person of ordinary skill in the art would have had at least a Bachelor of Science in electrical engineering, computer engineering, computer science, or a related field, with at least two years of relevant work experience in wireless communications and/or networking systems, or equivalents thereof. []. Superior education could compensate for a deficiency in work experience, and vice-versa. []. Pet. 3–4 (citing Ex. 1003 ¶ 21). Patent Owner does not propose a level of ordinary skill. See Prelim. Resp. Petitioner’s proposal is supported by the testimony of Dr. Traynor and is consistent with the ’260 patent. Accordingly, we apply Petitioner’s articulation.” slip op. at 17

“On the current record, Patent Owner’s claim construction arguments are unpersuasive. First, Patent Owner has not shown that the authentication requirement in its construction is supported by the intrinsic record. Patent Owner’s proposed construction requires that the user identifier be a “text string” that “contains sufficient information to authenticate a user of the web service.” Prelim. Resp. 35. Patent Owner’s authentication requirement is not a part of the claim language, nor has Patent Owner attempted to show that a person of ordinary skill in the art would have understood the ordinary meaning of “user identifier” to require such. Authentication does appear in the ’260 patent in the context of BT. Specifically, BT “can crypto graphically authenticate the identity of another BT device.” Ex. 1001, 3:61– 63. Authentication of the user does not appear in the specification. The only intrinsic evidence support Patent Owner cites are figures and related disclosure describing a preferred embodiment in the ’802 application.9 The disclosure uses different terms, e.g., “user preferences” and “login information,” which on this record Patent Owner has not sufficiently connected to the “user identifier” in claim 1.
