“We are not persuaded that exclusion of the cited portions of Dr. Chambliss’ testimony or Exhibits 1073, 1074, 1075, 1082, 1083, 1084, 1085, 1086, 1088, and 1090 is warranted. While the parties disagree on the merits of Dr. Chambliss’ testimony as to whether PGGs were known to be gelling agents by persons of ordinary skill in the art at the time of the Priority Applications, Patent Owner does not persuade us that Dr. Chambliss fails to support his testimony with any reasonable logical or scientific basis. The exhibits that Patent Owner seeks to exclude, which include a patent, technical references, and a journal article, are relevant to the inquiry Dr. Chambliss performed in forming his opinion. We therefore do not see a basis for exclusion under FRE 702/703 or 37 C.F.R. § 42.64(c). Moreover, we find this evidence both admissible and relevant as it concerns a fundamental issue for our patentability analysis. Thus, we decline to exclude the evidence under FRE 401 or 402.” slip op. at 12

“would have possessed “a degree in one or more fields of medicine, chemical engineering, chemistry, pharmaceutical science, and/or pharmacology and a number of years of industry training or experience in one or more of those fields.” Pet. 21 (citing Ex. 1002 ¶ 82). Petitioner further proposes that “[i]f the degree is a Ph.D[.], then the required industry experience need not be significant, e.g., two years or more, but if the technical degree is a B.S. or M.S., then the industry experience would be more significant, e.g., five years or more.” Id. We preliminarily adopted Petitioner’s definition of a POSA’s skill level in our Institution Decision as it was undisputed at the time and consistent with the evidence of record. Inst. Dec. 7–8. Neither Patent Owner nor Petitioner addresses the level of ordinary skill in the art in the post-institution briefing. We continue to adopt Petitioner’s proposed skill level for a POSA herein and have also taken into account the level of skill reflected in the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Applying this level of skill, we find that Dr. Chambliss and Dr. Constantinides are qualified to provide opinions as to the perspective and knowledge of a POSA. See Ex. 1002 ¶¶ 81–83; Ex. 2030 ¶¶ 58–63.” slip op. at 8

“We agree with Patent Owner that the challenged claims recite methods of making formulations using recited features and ingredients. In addition, as we stated in our Decision on Institution, “[t]he claims define abuse deterrence in terms of when the dosage form is ‘subjected to t[a]mpering comprising heating at a temperature greater than about 45° C.’” Inst. Dec. 19 (quoting Ex. 1001, 41:50–52). Additionally, the claims and specification identify specific ingredients that can purportedly help achieve this abuse deterrence functionality. Id. Given these conclusions, further construction of “abuse deterrent,” which both parties generally agree relates to methods of making the drug dosage form less likely to be abused, is not necessary to resolve the issues before us.” slip op. at 9

“Notwithstanding these individual teachings, we find that the specification fails to demonstrate that the inventors of the ’961 patent possessed a dosage form comprising a combination of the recited components that also satisfied the recited functionality. We are persuaded that the specification fails to provide sufficient guidance that would have led the POSA to create the recited dosage form. See Fujikawan 93 F.3d at 1571; In re Ruschig, 379 F.2d 990, 995 (CCPA 1967). Rather, “one is left to select[] from the myriads of possibilities encompassed by the broad disclosure, with no guide indicating or directing that this particular selection should be made rather than any of the many others which could also be made.” Ruschig, 379 F.2d at 995.” slip op. at 34

“We have the authority and discretion to determine whether to institute a post grant review. 35 U.S.C. § 324; 37 C.F.R. § 42.4(a) (2021). We may not institute a post-grant review unless “the information presented in the petition . . . , if such information is not rebutted, would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a). After considering the briefing and the evidence of record, we conclude that Petitioner has failed to establish a reasonable likelihood of prevailing in demonstrating that the challenged claims are unpatentable over the cited prior art in asserted grounds 2–5. With regard to ground 1, Petitioner’s written description ground, we determine that Petitioner’s arguments are substantially the same as those previously presented to and considered by the Office, and we exercise our discretion under 35 U.S.C. § 325(d) and decline to institute post-grant review of the ’542 patent on that ground alone.” slip op. at 2

“We agree with Patent Owner that Petitioner’s arguments regarding whether the ’542 patent provides § 112 written description support for the challenged claims are substantially the same as those considered by the Examiner during the prosecution of the ’542 patent. As set forth above, the Examiner repeatedly rejected the pending claims because (1) the claims were overly broad in light of the guidance provided in the specification that was limited to the working examples specific to exon 7 of a gene encoding a MLH3 subunit (Ex. 1006, 623–24); (2) the claims did not enable the oligonucleotides to “hybridize[] to a complementary target nucleic acid sequence of a gene or gene product to modulate the expression of a component of a mismatch repair (MMR) complex” based on the disclosure of the specification, which was limited to the working examples (id.); and (3) the claims did not enable a pharmaceutical composition of the recited nucleotide base length range for the entire scope of the claims based on the disclosure of the specification, which was limited to the working examples (id. at 1183–84). The rejections were based on a broad reading of the claims as interpreted by the ordinarily skilled artisan, and required analysis of whether there is sufficient support in the specification for the entire scope of the claims. Applicant overcame these issues by narrowing the claims until the Examiner agreed that the support present was sufficient.” slip op. at 36
- Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableMotivation not found
“We agree with Patent Owner that Petitioner’s allegations regarding the skilled artisan’s reasons to combine are conclusory and insufficiently supported by evidence. Petitioner cites Dr. Wood’s testimony to explain why the skilled artisan would have understood that Fuselier’s suggestion to “switch[] isoforms of MLH3” could be accomplished by manipulating pre-mRNA splicing to delete exon 7. Petitioner’s discussion on pages 59–60 quotes phrases from Dr. Wood’s referenced testimony, see Ex. 1002, ¶¶ 213–216, but the rationale appearing in the Petition merely comprises repetitive generalized statements akin to “Morcos is a powerful tool that can accomplish what Fuselier suggested.” See Pet. 59–60. Dr. Wood’s underlying testimony lacks key explanation as to the understanding of the ordinary artisan at the time of the invention. What Petitioner has not provided, as Patent Owner argues, are the reasons 1) why Fuselier’s suggestion to “switch[] isoforms” would have led the artisan to pursue deletion of exon 7; and 2) why the artisan would have selected Morcos’ time. See Prelim. Resp. 55–56.” slip op. at 19

“invention in the field of antisense technology “would have had knowledge of the scientific literature and have skills relating to approaches for utilizing synthetic oligonucleotides to manipulate gene expression” and “have been well-experienced in laboratory techniques and strategies for designing and making SSOs, conducting in vitro and in vivo testing, and application of SSOs in research.” Pet. 18 (citing Ex. 1002 ¶¶ 30, 31). Petitioner adds that the artisan “would have had knowledge of laboratory techniques and strategies in creating nuclease-resistant SSOs, and using such SSOs to manipulate gene expression to force expression of selected isoforms of a M.D. or a Ph.D. in physiological science, biochemistry, molecular biology, chemistry, or a related discipline, with at least five years of experience in SSOs design and manipulation” and may have “worked as part of a multidisciplinary team” to permit input by others on the team with specialized skills to assist in solving problems. Id. Patent Owner does not contest the skill level provided by Petitioner for the purpose of deciding institution (Prelim. Resp. 4), and we adopt it as reasonably consistent with the level of skill represented by the ’542 patent and the art of record.” slip op. at 8
