“Patent Owner does not contest Petitioner’s proposed definition, except to modify the level such that an ordinarily skilled artisan “would have been familiar with well-known inhibitors of IL-15 and IL-15R as described in the ’505 patent and recognized in the art as of April 2017.” Resp. 26–27 (citing Ex. 2005 ¶ 94). We adopt Petitioner’s level of ordinary skill in the art with Patent Owner’s proposed modification because it appears consistent with the problems addressed in the ’505 patent and the prior art of record.” slip op. at 7

“Finally, we are reminded that “a sufficient description of the genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350. “[F]unctional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. Here, however, the challenged claims are directed to methods using a wide range of different types of compounds purported to be “IL-15/IL-15R inhibitors” that are not part of a known or readily identifiable class, do not target the same biological pathway, do not have any common structural features, and do not appear to always function as inhibitors. See Ex. 1018, Abstr., 1575–77, 1579; Ex. 1046, 189:4–19, 191:15–192:15, 193:18–196:22, 198:21–199:21, 197:12–198:19, 200:1–8, 207:11–14, 203:3–10, 207:15–21, 236:12–24; Ex. 1047 ¶¶ 19–23, 56, 63–64, 80–85.

“598 U.S. at 610. A “specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it. See Ex. 1047 ¶¶ 10, 25–26, 53; Ex. 2013, 2:10–18; Ex. 2014, 2:12–20; Ex. 2015 ¶ 3; Ex. 2025, 2:10–18; Ex. 2078, 267.” slip op. at 32

“VIII. LEVEL OF ORDINARY SKILL IN THE ART Petitioner asserts A person of ordinary skill in the art (“POSA”) in the field of the patent between 2012 and 2021 would have held an MD with experience in clinical oncology or pharmacology; a PhD in pharmacology, pharmaceutical chemistry, cancer biology, or a related discipline; or a PharmD with experience in clinical oncology. Ex. 1020 ¶ 29. A POSA would also have practical working knowledge of oncology (Ex. 1020 ¶ 29) and experience with the design of studies necessary for drug development. This description is approximate, and additional experience could make up for less education and vice versa. Ex. 1020 ¶ 29. Pet. 15–16. Patent Owner asserts “that a POSA for purposes of the ’087 Patent would have had at least an M.D. and several years of experience treating patients with hematological malignancies (i.e., blood cancers).” Prelim. Resp. 13. Patent Owner asserts “Petitioner’s definition fails to require experience specific to hematological malignancies or blood cancers. Patent Owners’ definition of a POSA, on the other hand, accounts for the claims’ focus on lymphoma and leukemia.” Id. at 14. At this stage in the proceeding, we find that Patent Owner’s analysis more precisely establishes the level of ordinary skill in the art as it directly relates to those deciding prescribing information based on the prior art reference. See Ex. 1011, 2. The level of ordinary skill in the art usually is evidenced by the prior art references themselves. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Nor does our consideration of the issues presented turn on which proposed definition is applied. In any event, having considered the evidence and the arguments, we find Patent Owner’s rationale for its more narrow description of the level of ordinary skill in the art to be persuasive and Patent Owner’s description of a person of ordinary skill in the art, while maintaining that the prior art reflects the appropriate level of skill at the time of the claimed invention.

According to Patent Owner, “[t]he term ‘porcine circovirus type 3 recombinant protein’ has a plain and ordinary meaning of ‘genetically engineered PCV3 protein.’” Id. (citing Ex. 2052 ¶¶ 91–92). Having considered the positions of both parties, and the evidence of record, we find that for purposes of this Decision, the ordinary and customary meaning of the claim term “porcine circovirus type 3 recombinant protein,” is a PCV3 protein obtained by genetic engineering, and specifically by recombinant technology, wherein the recombinant protein may either have the same structure and same amino acid sequence as variation therein.

“In the Patent Owner Response, Patent Owner asserts that “[a] POSITA would have understood ‘the nucleotide sequence encoding [ORF1, ORF2 or ORF3]’ to mean ‘a nucleotide sequence having at least 90% sequence homology with SEQ ID NOS. 3, 5, or 7 or encoding a sequence having at least 90% sequence homology with SEQ ID NOS. 4, 6 or 8.’” PO Resp. 24 (citing Ex. 2052 ¶¶ 93–96). In support of that position, Patent Owner refers to the following Specification description: [a] preferred PCV3 ORF2 protein is that of SEQ ID NO. 6, but it is understood by those of skill in the art that this sequence, as well as those for ORF1 and ORF3 could vary by as much as 10% in sequence homology and still retain the antigenic characteristics that render it useful in immunogenic compositions. Patent Owner asserts, according to that Specification description, “the sequences described and identified by SEQ ID Nos. in the patent for PCV3 ORF1, ORF2 and ORF3 are representative sequences, and ‘ORF1,’ ‘ORF2’ and ‘ORF3’ in the patent also refers to those sequences with at least 90% sequence homology.” Id. (citing Ex. 2052 ¶ 95; Ex. 2006, 107:9–17). Further, Patent Owner asserts this interpretation is consistent with the language of the other claims. In particular, Patent Owner refers to the limitation in claim 1 reciting that the composition comprises a PCV3 recombinant protein selected from “ORF1, ORF2 and ORF3, wherein said protein is encoded by a nucleotide sequence having at least 90% sequence homology with a sequence selected from the group consisting of SEQ ID NO. 3, SEQ ID NO. 5, SEQ ID NO. 7.” Id. (quoting Ex. 1001, 71:14–21). Having considered the positions of the parties, and the evidence of record, we agree with Patent Owner that the Specification provides clarity and meaning for the use of the terms ORF1, ORF2, and ORF3, which are not set forth or defined in claim 4, from which claim 5 depends, or in claim 5. Petitioner, in its alternative argument regarding the construction of the phrase involving those terms in claim 5, agrees to some extent. See Pet. 26. For purposes of this Decision, and for the reasons discussed by Patent Owner, we construe the claim phrase “nucleotide sequence encoding ORF1, . . . ORF2, and . . . ORF3” recited in claim 5 as meaning “a nucleotide sequence having at least 90% sequence homology with SEQ ID NOS. 3, 5, or 7 or encoding a sequence having at least 90% sequence homology with SEQ ID NOS. 4, 6 or 8.”” slip op. at 13

“We do not find that description to be adequate. Essentially, the Specification description that the sequences for PCV3 ORF 1, 2, and 3, could vary by as much as 10% sequence homology just rephrases what is claimed in terms of those sequences having at least 90% sequence homology, adding only that antigenic characteristics are retained that render it useful for immunogenic compositions. A claim, however, “does not become more descriptive by its repetition,” see Ariad, 598 F.3d at 1350 (quoting Eli Lilly, 119 F.3d at 1568), and “a definition of a useful result rather than a definition of what achieves that result” does not sufficiently Inc. v. Gen-Probe Inc., 323 F.3d 956, 969 (Fed. Cir. 2002)). As noted by Petitioner and Dr. Nordgren, the ’351 patent discloses nucleotide and amino acid sequences corresponding only to the naturally-occurring PCV3 ORFs 1–3. PO Resp. 52; Ex. 1026 ¶ 168. While those sequences may be characterized as “reference” sequences, as they reflect sequences with 100% homology with PCV3 ORFs 1–3, Patent Owner has not demonstrated that they are “representative” sequences for the broad range of sequences claimed. We find that the Specification does not reasonably convey that the inventor made or was otherwise in possession of any of the remaining members of the genus with at least 90% sequence or amino acid homology with ORFs 1–3. PO Resp. 53; Ex. 1026 ¶ 168. We find that Dr. Nordgren credibly characterizes the Specification, as follows: [T]he ’351 Patent outlines a preliminary research plan to eventually make and use the broad range of claimed proteins. That is, the inventor provides a number of DNA and primer sequences that could be used to clone homologous DNA sequences into an expression vector, and theorizes that proteins expressed from sequences having 90% sequence homology will be antigenic. Critically, however, the ’351 Patent does not disclose which of the thousands of different claimed homologous sequences, if any, the inventor possessed, much less had discovered to be antigenic. Instead, the inventor merely proposes, without any factual support, that PCV3-derived amino acid sequences “could vary by as much as 10% in sequence homology and still retain the[ir] antigenic characteristics.” Ex. 1001 at 8:49-56. A POSITA would not credit that unsupported speculation, and therefore would not believe that the inventors possessed such a wide range of proteins.” slip op. at 33
