“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.

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.”).

“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 find that a rigid requirement as to the subject of a POSITA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining that “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSITA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program). We also find that evidence of record supports Petitioner’s assertion that, for purposes of defining a POSITA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 22; Ex. 1065, 99:14–100:3. Accordingly, based on the entirety of the trial record, we find a POSITA with respect to the claims of the ’109 patent would have had a two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa.

Patent Owner argues that, contrary to what Petitioner’s argument allegedly implies, “Claim 1 is directed to a method for producing an endotoxin assay agent” and does not require the use – Owner that claim 1 does not require the use of endotoxin assay agent.

“In this case, to show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23–24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). In our Institution Decision, we stated: Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)). Thus, the information presented in the Petition, which is limited to the perspective of a 2013 POSITA, does not demonstrate that it is more likely than not that at least 1 of the claims challenged in the Petition is unpatentable for lack of written description. Inst. Dec. 12 (alterations in original). During trial, Petitioner did not present any further arguments in support of Ground 1. See generally Pet. Reply.

“Although the evidence before us shows that, in 2013, a POSITA knew how to recombinantly express genes in expression systems such as CHO or HEK-293 cell lines, the evidence shows that this was true only for genes whose genetic sequences were known or readily available. See, e.g., Ex. 1069, 34:11–22 (“Q. Okay. So you would agree that the creation of the recombinant protein requires the underlying sequence of, as you said, the original animal? A.

“The plain language of claim element [1.A] recites “wherein the first material layer is disposed over a first portion of the second material layer;” and claim element [1.B] recites “a landing pad disposed over a second portion of the second material layer.” Thus, the plain language of the claim merely recites that the first material layer is disposed over a first potion of the second material layer and the landing pad is disposed over a second portion of the second material layer. The plain language does not define what constitutes the first or second portions of the second material layer or define the first or second portions of the material layer by what is disposed above the layers. We agree with Petitioner that the term “portion” has a straightforward plain and ordinary meaning: a “part” of a larger whole. Pet. 5 (citing Ex. 1077, 406 (defining “portion” as “a part of a whole”)). The ’838 patent itself repeatedly uses the term “portion” this way. Ex. 1001, 5:40–43 (discussing both “an upper portion” and “lower portion” of a “staircase”), 5:66–6:1 (referencing “a portion of a top surface of a layer”); see also 4:39– 40, 7:15–17, 8:20–33, 8:34–65, 11:60–64, 12:38–59.

And, although indicia appearing within a reference can sometimes support the printed publication status of the reference, I find the record to be devoid of any such indicia, or other evidence, supporting that Biomed was publicly disseminated or accessible by the June 15, 2021 “date of revision.” See Hulu, Paper 29 at 16–18.

“sufficiently that Biomed qualifies as a prior art printed publication. The Board’s precedential decision in Hulu, LLC v. Sound View Innovations, LLC, IPR2018-01039, Paper 29 (PTAB Dec. 20, 2019) (precedential), addresses prior-art qualification in the related context of instituting an inter partes review. Hulu states that “the petition must identify, with particularity, evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent and therefore that there is a reasonable likelihood that it qualifies as a printed publication.” Id. at 13; see also Jazz Pharm. Inc. v. Amneal Pharm., LLC. 895 F.3d 1347, 1356 (Fed. Cir. 2018) (“[T]he IPR petitioner . . . had the burden to prove that a particular reference is a printed publication.”). The same guidance applies to post-grant reviews, albeit with the “more likely than not” standard applicable. See 35 U.S.C. § 324(a); Hulu, Paper 29 at 13 n.5. Hulu also states that “there is no presumption in favor of institution or in favor of finding a reference to be a printed publication under [37] § 42.108(c).” Hulu, Paper 29 at 16.

“because the “user interface” limitations merely apply the recited abstract idea on a generic mobile device without meaningfully limiting the abstract idea. See 2025 Guidance, at 4–5. For example, these limitations do not reflect an improvement to the functioning of the mobile device (or any other computer device), and instead are “mere instructions to implement an abstract idea or other exception on” the mobile device.
