    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “As to the first issue, we agree with Patent Owner that defining the level of skill in view of the solution described in the patent risks improper hindsight. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) 18 (“[T]he level of skill in the art is a . . . lens through which . . . the Board views the prior art and the claimed invention,” which “prevents . . . factfinders from using their own insight or . . . hindsight[] to gauge obviousness.”). We therefore do not include “practical knowledge about . . . the deuterium isotope effect, including the patents and publications discussed [in the Petition],” as part of our definition of a person of ordinary skill in the art.” slip op. at 18

      “person of ordinary skill in the art would employ” in an obviousness analysis, we give some weight to Dr. Guengerich’s testimony. KSR, 550 U.S. at 418; Plantronics, Inc. v. Aliph, Inc., 724 F.3d 1343, 1354 (Fed. Cir. 2013) (explaining that “motivation to combine may be found. . . in . . . the background knowledge, creativity, and common sense of the person of ordinary skill”). Nevertheless, even if we were to agree that an ordinarily skilled artisan would have seen the 1,5-shift in NRPE in Mata’s A2E biosynthetic pathway as a particularly desirable location for intervention, we are not persuaded that such a person would have been motivated to substitute C20 deuterated vitamin A for the vitamin A in Ortho Pharma’s composition and method, because Petitioner has not shown, by a preponderance of evidence, that such an artisan would have reasonably expected the substitution to retard the accumulation of A2E or to treat macular degeneration.” slip op. at 42

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

      “In our Institution Decision, we preliminarily construed the preamble of claim 28 as limiting. Inst. Dec. 30–31. Petitioner did not take issue with our construction, or dispute Patent Owner’s construction of the preambles of claims 1 and 29 as also limiting. After consideration of the full trial record, we maintain our construction of the preamble of claim 28 as limiting for the reasons set forth in our Institution Decision. For similar reasons and the reasons set forth in Patent Owner’s Response, we further construe the preambles of claims 1 and 29 as limiting. See PO Resp. 12–14. We further determine that we do not need to construe any other claim term in order to resolve the controversy between the parties. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

      “Patent Owner’s contentions are, at this stage, unavailing because Patent Owner’s proffered definition of a POSA is too restrictive. Petitioner’s proposal is sufficiently comprehensive to encompass the level of skill reflected in prior art relevant to the ’298 patent. It is reasonably clear that, in indicating that a POSA would have an advanced degree (like a Ph.D.) and years of experience in analysis of protein structure, Petitioner is asserting that knowledge of proteins generally is sufficient to understand the types of problems encountered in the art and the prior art solutions to those problems, and the ordinary artisan need not be an expert in hyaluronidases. See Pet. 16. Petitioner requires that the POSA would be able to apply key scientific concepts (e.g., biochemistry, recombinant biology, sequence analysis and protein modeling) to enzymes such as hyaluronidases. See id. Moreover, Patent Owner fails to persuasively explain why Petitioner’s definition that includes a person with expertise in other enzymes is insufficient. Even if we were to apply Patent Owner’s POSA definition, it is not clear on the record before us that Petitioner’s experts lack relevant expertise or qualifications of at least a POSA. Patent Owner will have the chance to cross-examine Dr. Hecht and Dr. Park in this proceeding to develop a full record for us to determine the weight that each expert’s testimony should be given. Patent Owner will have further opportunity on a full record to assert that we should discount either experts’ testimony due to lack of appropriate qualifications. At this stage of the proceeding and on the record before us now, we apply Petitioner’s proposed POSA level, which appears consistent with the level of skill shown in the prior art references of record.

      “posttranslational modifications and those that do not contain chemical or posttranslational modifications.” Id. at 44:59–62. The ’298 patent provides an express definition of the term “modified PH20 polypeptide” which refers to a PH20 polypeptide that contains at least one amino acid modification, such as at least one amino acid replacement as described herein, in its sequence of amino acids compared to a reference unmodified PH20 polypeptide. A modified PH20 polypeptide can have up to 150 amino acid replacements, so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity. Typically, a modified PH20 polypeptide contains 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 amino acid replacements.

      “on the ’429 patent, and there is no evidence of record that the Examiner meaningfully considered the relevant disclosures of the ’429 patent. We find unpersuasive Patent Owner’s reliance on the Examiner’s issuance of an office action with a written description rejection over a different issue that also included some double patenting rejections. As to Becton, Dickinson Factor (e), “whether Petitioner has pointed out sufficiently how the [E]xaminer erred in its evaluation of the asserted prior art,” Petitioner provides persuasive evidence of Examiner error. See Pet. 36–39 (citing Ex. 1009, 21–27). We agree with Petitioner that the Examiner overlooked the written description requirement with regard to claim 1. As discussed below, we find that, on the current record, the evidence sufficiently shows that it is more likely than not that the claims fail to comply with the written description requirement. See Section X. We, thus, find that the Examiner erred by either overlooking, or failing to appreciate, the factual underpinning necessary to support a written description for the breadth of an enormous genus claim such as claim 1 of the ’600 patent.” slip op. at 22

Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981.

    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “The parties’ positions about the level of ordinary skill in the art are similar. (See Pet., 13–14; see PO Resp., 10–12.) In light of the parties’ arguments and evidence, we determine that the ordinarily skilled artisan would have had a bachelor of science degree in a relevant life sciences field, such as chemistry, biochemistry, or pharmacy, with at least three to four years of work or laboratory experience in pharmaceutical formulations and would have had access to team members having experience in pharmaceutical formulation and pharmaceutical regulatory approvals. (See Pet. 13–14; see PO Resp. 10–12; see Dec. 6–7.) Both of the parties’ proposals as to the level of ordinary skill in the art are consistent with the disclosure of the ’795 patent and the asserted prior art. The distinction between the parties’ proposals is minimal and would not change the outcome of this Decision. Thus, we adopt and apply Patent Owner’s proposal.” slip op. at 6

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “Although Petitioner puts forth constructions for terms in the claims of the ’795 patent, Patent Owner argues that we need not expressly construe any terms to resolve the controversy between the parties. (See Pet. 14–19; see PO Resp. 12.) Except as indicated below, we agree that express construction of the claim terms is not required because the parties do not materially dispute the meanings of the terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Limitation (c) of claim 1 recites “syrup formulation” once and then “syrup” by itself twice. The parties agree that two recitations of “syrup” by itself mean and are synonymous with “syrup formulation.” (See Tr. 15:16– 19 (counsel for Petitioner: “[T]he term, syrup, by itself, means the formulation. And for that reason, we--it’s our position that it’s the syrup formulation that has the specific viscosity requirements as well as the other features that we discussed.”); 31:17–20 (counsel for Patent Owner: “But those wherein clauses, what it’s referring to, the syrup formulation and the syrup -- it was all to a complete to a final formulation, right, it’s not just the agave syrup. Everybody here recognizes and understands that from that perspective.”).) Thus, the parties agree that the “viscosity of less than 1500 centipoise at about 22 degrees” limits the final “pharmaceutical syrup formulation for oral administration,” not the “agave syrup” limitation in limitation (b) of claim 1.” slip op. at 7

      “Patent Owner argues further that Dr. Crowley testifies that, “[g]enerally, suspensions having a viscosity in the range of 20 to 150 cP are considered readily pourable,” but that this range is well below the viscosity range of 200–900 cP taught in WO133 and the preferred viscosity range of 1000–3000 cP taught in the ’4666 patent. (See PO Resp. 45 (quoting Ex. 1003 ¶ 59).) Dr. Crowley testifies that “increasing the viscosity of a suspension formulation has been shown to impair the dissolution characteristics of immediate release acetaminophen” and that, “[w]ith respect to suspensions for oral administration, having a higher viscosity is generally not desirable.” (Ex. 1003 ¶ 59.) According to Patent Owner, this is a “teaching away” because Petitioner’s own expert testimony demonstrates a motivation not to combine the acetaminophen formulation of FR458- Example 1 with the 1000-3000 cP range of the ’4666 patent and the 200-900 cP range of WO133 since by his own admission doing so would yield bad results (i.e., impairing the dissolution characteristics of the acetaminophen) and generally undesirable higher viscosity. (PO Resp. 46 (citing Berkland Decl., Ex. 2009 ¶ 148).) Dr. Crowley’s cited testimony, however, is about general characteristics of suspensions for oral administration, whereas the WO133 refers specifically to sweetened analgesic formulations. (See Ex. 1006, 8:1– 3 (“The viscosity of the acetaminophen composition generally ranges from about 200–900 centipoise, preferably from about 300–700 centipoise.”); see Pet. Reply 8–9.) As Petitioner notes, Dr. Crowley also testifies that the viscosity of 29 commercially available, pediatric liquid oral antibiotic formulations were measured and determined to range from 20 to 1,780 cP” and that “[t]he viscosity of Children’s Tylenol has been reported to be less than 1,000 centipoise at shear rates between 0.05 and 0.2 reciprocal seconds.” (Ex. 1005 ¶ 58.) Thus, we are not persuaded that Dr. Crowley’s testimony contradicts the teachings regarding viscosity of analgesic formulations in the cited prior art.” slip op. at 23

      “As an initial matter, two criteria determine whether prior art is analogous: “(1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Clay, 966 F.2d 656, 658–59 (Fed. Cir. 1992). We find that, at this stage of the proceeding, Petitioner has sufficiently shown that Kanan and Neri are and/or are reasonably pertinent to the problem which the inventor is involved, in particular “encoding individual members of a library of chemicals with unique nucleotide sequences that can later be detected and analyzed to determine the identification of the members involved in the interaction.” Pet. 17.” slip op. at 22

      “argument does not undermine Petitioner’s challenge at this stage. In particular, Petitioner has explained that the modification of Kanan with Neri’s self-assembly sequence would “reduce the time to synthesize a library where all members can interact.” Pet. 18 (citing Ex. 1005 ¶¶ 97–101). Similarly, Petitioner has explained the reason for including a “coding region” for each library member, i.e., to “provide a unique nucleic acid identification sequence for each conjugate that can be identified downstream,” as for instance taught by Neri. Id. at 30 (citing Ex. 1005 ¶ 97). Finally, Petitioner has explained “a POSA . . . would . . . add the d-spacer taught in Neri, as this prevents the identification sequence element of pool B members from interacting with the identification sequence element of supports Petitioner’s contentions and that testimony is, at present, substantively unrebutted. On the record before us, and at this preliminary stage of the proceeding, we do not find Petitioner’s asserted motivations to be improperly disparate or based on hindsight. In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (explaining that reconstruction of prior art is not improper “so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). To the extent Patent Owner is also arguing that Petitioner’s assertions regarding reasonable expectation of success are unsupported, Prelim. Resp. 24, the argument is similarly unavailing. Petitioner has pointed to teachings in Neri and the knowledge of an ordinarily skilled artisan to support its assertions. Pet. 21–23 (citing, e.g., Ex. 1005 ¶¶ 104–105, 149, 171, 183 and Ex. 1011 ¶¶ 10, 82 to explain why an ordinarily skilled artisan would have reasonably expected success in applying, to Kanan’s small molecules, Neri’s “method of preparing organic molecules, peptides, and oligomeric proteins linked to an oligonucleotide that results in stable self-assembled associated oligonucleotides”). In this regard, we note that “the expectation of success need only be reasonable, not absolute.” Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007).” slip op. at 25
