“III. CONCLUSION Because we determine that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing at least one of the challenged claims is unpatentable, we institute inter partes review as to all challenged claims and grounds presented in the Petition. At this stage of the proceeding, we have not made a final determination as to the patentability of any of these challenged claims. ORDER For the reasons given, it is ORDERED that pursuant to 35 U.S.C. § 314, an inter partes review is instituted as to claims 1, 2, 5–8, 11, and 12 of the ’803 patent to determine whether: 1) claims 1, 5–7, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over TS 36.300, TS 36.321, and TS 36.331; 2) claims 1, 2, 5–8, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson and TS 25.331; and 3) claims 5, 6, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson, TS 25.331, and Sebire; and” slip op. at 27
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

“f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34. On this preliminary record, we are persuaded that Petitioner has made a sufficient showing that a POSITA would have had a reason to combine the teachings of Ericsson and TS 25.331.” slip op. at 20

At this stage in the proceeding, Patent Owner does not contest Petitioner’s proposal or offer an alternative. On this record, we are persuaded that Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art.

Indeed, while some of the language in the above paragraph is permissive in nature, i.e.., describing the number of amino acid replacements a modified PH20 polypeptide “can have” or “[t]ypically . . . contains” or the other modifications the polypeptide “can include,” the phrase “so long as” is not.

Thus, the evidence of record shows the ’791 patent recognizes a broad understanding of a “modified PH20 polypeptide” as encompassing PH20 sequences from a variety of different mammalian species, with or without precursor or signal sequences, with or without post-translational modifications, and with up to 150 amino acid replacements. The express definition of “modified PH20 polypeptide” in the ’791 patent permits up to 150 amino acid replacements but only “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 47:9–11. That is, the provided definition of “modified PH20 polypeptide” in the ’791 patent expressly requires some hyaluronidase activity. On the current record, we therefore adopt the definition for “modified PH20 polypeptide” as recited in the ’791 patent to encompass polypeptides with some hyaluronidase activity. We determine that we need not expressly construe any other claim terms for the purpose of deciding whether to institute post-grant review. See Nidec Motor Corp. v.

“As we noted, on the current record claim 1 is reasonably interpreted to encompass PH20 polypeptides with some hyaluronidase activity. But even if we were to find that immunization using PH20 polypeptide as a contraceptive antigen serves to satisfy the utility requirement for the instant claims, there is a similar concern as to whether modified PH20 polypeptides with significant differences from the native protein as encompassed by claim 1 would maintain the antigenic determinants necessary to function as contraceptives. See Ex. 1003 ¶ 122. That the modified PH20 polypeptides would be homogenous in function is contradicted both by evidence in the ’791 patent itself and by Dr. Hecht and Dr. Parker. The ’791 patent discloses synthesis of 6,753 single amino acid mutations in residues 1‒447 of SEQ ID NO: 3. See Ex. 1001, 199:15–200:34. The ’791 patent teaches that just under 10% of these mutations, i.e. over 600, “exhibit activity that is increased compared to wildtype.” Id. at 233:1–2. Appendix A of Dr. Hecht’s Declaration shows 3,380 of these mutations were inactive, or 57.13%. See Ex. 1003, Appendix A-1, 171. Thus, the ’791 patent evidences that even when only a single mutation is made in the PH20 polypeptide, that single mutation is more likely than not to alter the structure in such a way as to inactivate the hyaluronidase activity found in the native PH20 polypeptide. On this record, Dr. Hecht persuasively demonstrates that when the full scope of claim 1 is addressed, which includes not just single mutations in the PH20 polypeptide, but also multiple mutations, there is no expectation of structural homogeneity, stating that “[i]ntroducing multiple amino acid changes simultaneously . . . could prevent the folding of sequences into secondary structures and structural motifs and can destabilize those structures if they do form.” Ex. 1003 ¶ 59. Dr. Hecht notes that claim 1 allows “up to 21 changes, with each additional change (except at position 309) being to any of 19 alternative amino acids. But the up to 21 changes also can be at any of 433 different positions.” Id. ¶ 129. Dr. Park calculates that the number of distinct polypeptides that meet the claimed criteria “is extremely large by all accounts, ranging from 1049 to 1060 distinct polypeptides.” See Ex. 1004 ¶ 161. Dr. Hecht characterizes the number of possible mutations as “astronomical in size.” Ex. 1003 ¶ 134.” slip op. at 20

“Every patent must describe an invention. It is part of the quid pro quo of a patent.” Ariad, 598 F.3d at 1345. Ariad explains that for generic claims the question may still remain whether the specification, including original claim language, demonstrates that the applicant has invented species sufficient to support a claim to a genus. The problem is especially acute with genus claims that use functional language to define the boundaries of a claimed genus. In such a case, the functional claim may simply claim a desired result, and may do so without describing species that achieve that result. But the specification must demonstrate that the applicant has made a generic invention that achieves the claimed result and do so by showing that the applicant has invented species sufficient to support a claim to the functionally-defined genus. Id. at 1349. Ariad explains “that an adequate written description requires a precise definition, such as by structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Id. at 1350. Ariad also held that functional claim language can meet the written description requirement when the art has established a correlation between structure and function. . . . But merely drawing a fence around the outer limits of a purported genus is not an adequate substitute for describing a variety of materials constituting the genus and showing that one has invented a genus and not just a species.

“The definition of “modified PH20 polypeptide” in the ’345 patent permits up to 150 amino acid replacements but only “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 47:8–11. That is, the definition of “modified PH20 polypeptide” in the ’345 patent expressly requires some hyaluronidase activity. On the current record, we therefore adopt the definition for “modified PH20 polypeptide” as recited in the ’345 patent to encompass polypeptides with some hyaluronidase activity. The ’345 patent provides a specific definition of the term “hyaluronidase domain,” i.e., a “region of about 340 amino acids in length that corresponds to amino acid residues 38-374 of the precursor human PH20 sequence set forth in SEQ ID NO:6.”6 Ex. 1001, 68:19–24.” slip op. at 9

“On this record, Dr. Hecht persuasively demonstrates that when the full scope of claim 1 is addressed, which includes not just single mutations in the PH20 polypeptide, but also multiple mutations, there is no expectation of structural homogeneity, stating that “[i]ntroducing multiple amino acid changes simultaneously . . . could prevent the folding of sequences into secondary structures and structural motifs and can destabilize those structures if they do form.” Ex. 1003 ¶ 59. Dr. Hecht notes that claim 1 allows “21-42 changes, with each additional change (except at position 307) being to 1 of 19 other amino acids. But the up to 21-42 changes also can be at any of between 430 and 465 (or, in the case of the broadest claims, 474) different positions depending on which unmodified PH20 sequence is used.” Id. ¶ 120. Dr. Park calculates that “95% sequence identity [i.e., the higher percentage identity recited by the narrowest of the challenged claims] to PH201-465 means that the protein can have 23 total changes,” and that where one of those changes is one of nine choices at position 307 as required by claim 1, the number of possible PH20 polypeptides with twenty-two additional changes is “extremely large by all accounts, ranging from 1059 to 10112.” See Ex. 1004 ¶¶ 178–179.

Id. at 48:38–64 (emphasis added). Based on this express definition, the current record does not support the interpretation of Dr. Triggs-Raine that the “term ‘modified PH20 polypeptide,’ therefore, has a purely structural meaning in the context of the specification.” Ex. 2055 ¶ 68. Indeed, when reproducing the definition from this column of the ’590 patent, Dr. Triggs-Raine does not include any text after the first period, stating that “is not part of the express definition of ‘modified PH20 polypeptide’” and “merely describes an upper limit for the number of modifications possibly allowing a modified PH20 polypeptide to exhibit enzymatic activity.” Ex. 2055 ¶¶ 67, 77–78. On this record, however, we find that the entire text quoted above is part of the definition of “modified PH20 polypeptide” because it continues to detail specific elements required including a requirement that replacements in the PH20 polypeptide are permitted “so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Ex. 1001, 48:44–46; see Ex. 2001 ¶ 48 (stating a “patent’s definition controls”). Dr. Triggs-Raine recognizes the “therapeutic use of hyaluronidases” and notes that “different hyaluronidases were known to have different functions and substrates.” Ex. 2001 ¶¶ 29, 113.7 That is, Dr. Triggs-Raine recognizes hyaluronidase activity as the primary utility for the modified PH20 polypeptides recited in claim 1.” slip op. at 15

“On the current record, the evidence shows it is more likely than not that the claims of the ’692 patent fail to satisfy the written description requirement because they “recite a description of the problem to be solved while claiming all solutions to it and . . . cover any compound later actually invented and determined to fall within the claim’s functional boundaries— leaving it to the pharmaceutical industry to complete an unfinished invention.” Ariad, 598 F.3d at 1353. Accordingly, on the current record, we find that Petitioner has demonstrated that it is more likely than not that the ’692 patent does not comply with the written description requirement. Similarly, the current record does not appear to provide evidence of possession of the full scope of the claims of the ’692 patent in the ’731 application or any of the subsequent divisional or continuation applications leading to the ’692 patent that claim priority to the ’731 application (which appear to all have similar specifications) for the reasons given above. Therefore, the ’692 patent might not receive the benefit of priority to the earlier filed applications, and based on this preliminary determination, is eligible for post-grant review because the effective filing date is no earlier than the ’692 patent’s filing date of December 19, 2022.

“Court provided a construction for “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service,” as recited in claim 1, and “enablement signal enabling one or more of an application, a function and a service.” Prelim. Resp. 1–6. Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. (citing Ex. 2001, 25–26)) to support its contention that the District Court construed the term “enabled,” as we determined in the prior proceedings, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Ex. 2001, 26; see also IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11. That is, a determination of whether a term is indefinite is not the same thing as construing a claim term. Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabled.” Ex. 2001, 26. Accordingly, although the referenced portion of the District Court’s Memorandum indicates that a POSITA could reasonably ascertain the scope of the claim (id.), nothing in the Memorandum provides a construction of “enabled” as Patent Owner contends. Prelim. Resp. 5. That is, we are unpersuaded that the District Court construed that “‘[a]n application, function, or service is ‘enabled’ by a PDK when it receives information from a PDK in exchange for an access key” or that “hybrid device” includes “an RDC that ‘enable[es] one or more of an application, a function, and a service’ when it forwards such a message to the application, function, or service.” Id. (emphasis omitted, alteration in original). Thus, as in the prior proceedings, we determine that “enabl[ing] one or more of an application a function, and a service” does not require receiving information from a PDK in exchange for an access key or forwarding a message to the application, function, or service.” Id.; see also IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11.” slip op. at 10

Patent Owner does not take issue with Petitioner’s proposed construction for “PDK” but instead requests that we “follow the District Court’s construction” for “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service,” as recited in claim 1, and “enablement signal enabling one or more of an application, a function and a service,” with respect to claim 10. Prelim. Resp. 1–2. Because the parties do not take issue with each other’s proposed claim constructions, there is no term of the challenged claims that is in controversy, and thus, we determine that no term requires explicit construction. See Realtime, 912 F.3d at 1375. However, although it is not necessary to construe the term to resolve the disputed issues before us, we note that Patent Owner provides arguments with respect to “enabling one or more of an application, a function, and a service” recited in claims 1 and 10. Prelim. Resp. 1–2. We addressed similar arguments with respect to these terms in previous proceedings with related patents (see IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11), and we similarly address Patent Owner’s contention in this proceeding.” slip op. at 7
