      “Accordingly, we find that Petitioner has not identified any challenged claim that has an effective filing date on or after March 16, 2013. For this reason, we find that Petitioner has not shown sufficiently that the ’265 patent is eligible for post-grant review. IV. CONCLUSION After considering the evidence and arguments presently before us, we determine Petitioner has not shown that the ’265 patent is eligible for post-grant review. Accordingly, we do not institute a post-grant review. V. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 324(d), the Petition is denied.” slip op. at 29

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “To interpret “stable,” we begin with how the term is used in independent claims 7 and 19. Both terms recite “stable” in relation to the pharmaceutical formulation as a whole by reciting “wherein the formulation is stable.” Ex. 1001, 189:62–190:27. From this, we conclude that the ordinary artisan, as defined above to have a relevant advanced degree and at least two years of experience in development or manufacture of therapeutic protein formulations, would have understood that the components of a “stable” formulation would maintain their integrity and desired function following preparation, including when stored as described. This meaning is supported by the following language in the specification pertaining to the disclosed pharmaceutical compositions: Pharmaceutical compositions according to the present invention are described in further details hereinbelow. In one aspect, the pharmaceutical compositions disclosed herein are physico-chemically stable and maintain the integrity of an antibody comprised in said pharmaceutical composition, for example when stored for 8 weeks at 40° C. as shown hereinbelow. Ex. 1001, 84:20–26. We also note, as Petitioner argued, that the prosecution history supports that the formulation components needed to remain functional during storage, and that Patent Owner cited to formulation integrity after a storage period of 8 weeks at 40° C as evidence of such integrity. Ex. 1004, 7380. As disclosed in the ’265 patent, Examples 9 and 12 measure function and identity of the components following storage to confirm formulation stability.” slip op. at 11

      “burden of showing that claim 7 or 14 lacks written description support in the priority application, which Petitioner has conceded provides the same support as the ’265 patent specification. In this regard, we agree that the reasoning in Fresenius likewise applies: there is no legal requirement that a patent specification must include test results or working examples demonstrating stability for every possible composition that is covered by the claims. Fresenius at 13, citing Ariad Pharms., 598 F.3d at 1352 (stating that “the written description requirement does not demand either examples or an actual reduction to practice”). Formulations 2 and 3, disclosed in the ’265 patent specification, which Petitioner acknowledges falls within the scope of claims 7 and 14 (Pet. 26–27 (citing Ex. 1002 ¶¶ 134, 135)), were shown to be stable for 8 weeks in a syringe. Moreover, the ordinary artisan was provided with guidance in making such formulations from the teachings of the specification and has additional knowledge from the art. See Ex. 1001, 85:32–94:35. Claims 7 and 14 identify specific structures (risankizumab) and required excipients within a defined pH range, which are stable as confirmed by testing results presented in the specification. Prelim. Resp. 33; Ex. 1001, 94:14–36. On this record, we conclude that the evidence presented does not establish that it is more likely than not that an ordinarily skilled artisan would not have reasonably believed that the inventors of the ’265 patent possessed the claimed subject matter, each limitation of which is demonstrated as supported in the specification. As we have interpreted the claim term “wherein the formulation is stable” to mean “wherein the formulation maintains the functional integrity of the antibody and other components, for example when stored for 8 weeks at 40° C,” the specification supports maintenance of functional integrity as shown by the stability of Formulations 2 and 3, including when stored for a period of time. For this reason, we find that Petitioner has not shown that the ordinary artisan would not have understood the inventors of the ’265 patent possessed the subject matter of claims 7 and 14 as of the filing date of the priority application.” slip op. at 23

      “We acknowledge that in the Fresenius case, the extensive testing disclosed in that specification supported the ordinary artisan’s ability to formulate stable compounds using such guidance, and that the specification here discloses less testing. See, e.g., Sur-Reply. 8–9. Nevertheless, it is Petitioner’s burden on this issue, and we are not persuaded that the concerns raised by Dr. Klibanov provide sufficient evidence of actual instability to justify institution on this record. See, e.g., Atlas Powder Co. v. E.I. du Pont De Nemours & Co., 750 F.2d 1569, 1577 (Fed. Cir. 1984) (finding lack of evidence that district court erred in upholding claims as enabled where defendant did not identify inoperable embodiments despite extensive testing). In particular, we are persuaded that, on this record, Petitioner’s lack of evidence of instability of any formulation falling within the limitations of claim 14 indicates that Petitioner has not established sufficiently, for purposes of trial institution, that it is more likely than not that an ordinarily skilled artisan would not have been able to practice the full scope of claim 14 invention based on the teachings of the specification.” slip op. at 28

      “Under § 120, a patent is entitled to the priority date of an earlier filed application if (1) the written description of the earlier filed application discloses the invention claimed in the later filed application sufficient to satisfy the requirements of § 112; (2) the applications have at least one common inventor; (3) the later application is filed before the issuance or abandonment of the earlier filed application; and (4) the later application contains a reference to the earlier filed application. In re NTP, Inc., 654 F.3d 1268, 1277 (Fed. Cir. 2011); see also 35 U.S.C. § 120 . As discussed above and in our Decision to Institute, the ’086 patent meets this criterion. While we agree with Petitioner that the face of the ’086 patent does not include a citation of the ‘701 application, the specification does contain a clear claim of priority back to the ’701 application.

    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)Institution denied meritsInstitution denied

      “Determining whether a patent is subject to the first-inventor-to-file provisions of the AIA, and therefore eligible for post-grant review, is straightforward when the patentee filed the application from which the patent issued before March 16, 2013, or when the patentee filed the application on or after March 16, 2013, without any priority claim. The determination is more complex, however, for a patent that issues from a “transition application,” that is, an application filed on or after March 16, 2013, that claims the benefit of an earlier filing date. See MPEP § 2159.04 (9th ed. Rev. 10.2019, June 2020). Entitlement to the benefit of an earlier date under 35 U.S.C. §§ 119, 120, 121, or 365 is premised on disclosure of the claimed invention “in the manner provided by § 112(a) (other than the requirement to disclose the best mode)” in the earlier application. See 35 U.S.C. §§ 119(e), 120. Thus, a patent that issues from a transition application is not available for post-grant review if the claimed subject matter complies with the written description and enablement requirements of § 112(a) for an ancestor application filed prior to March 16, 2013.” slip op. at 9

Undue experimentation is analyzed by applying the factors set forth in In re Wands, 858 F.2d 731 (Fed.

      “We do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a person of ordinary skill in the art must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of research experience, Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during a doctoral program). On this record, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding.

      “We are unpersuaded that Dr. Volek’s reliance on Exhibit 1066 as the sole source of his conclusion that certain doses of inorganic nitrate would have been lethal in the context of the claimed methods is sufficient to establish undue experimentation under the Wands factors. As Patent Owner argues, the working example disclosed in PCT1 discloses administration of a dose Dr. Volek states would have been lethal, but was not. Rather, the result of that experiment was a demonstrated decrease in glucose consumption by the participants, a benefit of increased endurance. Ex. 1008 ¶ 106. We agree with Patent Owner that this case is distinguishable from those cited by Petitioner for the reasons explained by Patent Owner (Prelim. Resp. 31–33), and also from the recent case by our reviewing court, Amgen, Inc. v. Sanofi, 987 F.3d 1080 (Fed. Cir. 2021). In Amgen, the court found the claims lacked enablement because the claims recited dual functional limitations, and potentially millions of antibody candidates could be found to fall within those limitations. Id. at 1088. The court found the examples provided in the specification insufficient to enable the full scope of the claims given the high effort required to screen and identify all such antibodies. Id. Here, as Patent Owner has observed, the only effort required to practice claims within the range in light of the working example is to “simply administer a different dosage to the human for which increased exercise endurance is desired,” which would have been within the scope of the ordinarily skilled artisan. Prelim. Resp. 31. Moreover, Patent Owner correctly notes that methaemoglobinaemia15, the source of the lethality cited in Exhibit 1066, does not result via the claimed method. Prelim. Resp. 30, citing Ex. 1066 at 14–15. As Patent Owner explains, Petitioner’s sole cited Exhibit, 1066, discloses a risk of development of methaemoglobinaemia, a condition where more than 10% of the haemoglobin is transformed into methaemoglobin.” Id. When the conversion to haemoglobin exceeds 70% the condition can be fatal.” Ex. 1066 at 14–15. Patent Owner explains that the inventors discussed the risk of development of methaemoglobinaemia, and explained in PCT1 that their methods do not cause a significant rise in the methemoglobin level in the test subjects.

      “As noted by the Drs. Nordgren and HogenEsch, the differences in these descriptions are “relatively minor.” See Ex. 1038, 238:21–24; Ex. 1039 ¶ 42. Dr. Nordgren explains that even under the higher skill level required by Patent Owner’s description of a POSITA, his opinions would not change. Id. at 1039 ¶ 42. Based upon our review, the differences in Petitioner’s and Patent Owner’s proposed definitions do not impact Petitioner’s grounds for unpatentability or Patent Owner’s responsive arguments. 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

      “We are persuaded that Petitioner’s proposed definition is unduly restrictive. The claims do not clarify the meaning of “requiring a reduction in systolic blood pressure”; hence, we rely on relevant disclosures in the specification and prosecution history. Phillips, 415 F.3d at 1312–19. The prosecution history adds no clarity to the meaning of this term. As noted by Patent Owner, the specification states that the claimed method seeks to lower the systolic blood pressure in a subject needing such a reduction “preferably to normal levels (about 140/80 mmHg”) and provides an example of a 43-year-old with hypertension whose “blood pressure was 142/99 on the day when the experiment started.” Prelim. Resp. 8–9. We agree with Patent Owner that these disclosures provide general guidance to the person of ordinary skill in the art that the upper bounds of normal systolic blood pressure is about 140 mmHg, and that a person “requiring a reduction in systolic blood pressure” is someone whose systolic blood pressure exceeds that general measurement. Moreover, as discussed above, Petitioner states that a person of ordinary skill in the art would have had a medical degree or equivalent study in fields such as “biochemistry, pharmacology, nutrition chemistry, or kinesiology” (Pet. 13) such that the term would have been interpreted by persons with a sophisticated understanding of human physiology according to the facts and circumstances presented and with the guidance of “about 140 mmHg” providing a general measurement guideline.

      “In view of the above, we find that one of ordinary skill in the art would have understood that even in high copy number lines, unpredictable effects such as gene silencing could prevent the accumulation of high levels of enzymes such as those listed in Table 4 of the ’870 patent. Moreover, even if high enzyme levels were achieved, the extent to which those enzymes would catalyze the desired reactions would have been unknown. Accordingly, from a quantitative standpoint, the evidence adduced points to a high level of unpredictability in the art. Focusing on the last step of the pathway illustrated in Figure 1 of the ’870 patent, Patent Owner also asserts that the ordinarily skilled artisan “knew how to introduce multiple additional copies of the key enzyme responsible for the rapid and efficient conversion of DPA to DHA, the Δ4 desaturase from Emiliana huxleyi, to achieve ratios of DHA to DPA approaching infinity, and conversion rates approaching 100%.” Sur-reply 21 (citing Ex. 2021 ¶¶ 136, 142 (stating that “no technical limitation prevents reaching a ratio nearing infinity,” i.e., 100% conversion of DPA to DHA)).
