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

      “We have authority to determine whether to institute a post-grant review under 35 U.S.C. § 324. Institution of a post-grant review is authorized by statute when “the information presented in the petition . . . 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). A post-grant review may also be instituted when “the petition raises a novel or unsettled legal question that is important to other patents or patent applications.” See id. § 324(b). Applying that standard on behalf of the Director (37 C.F.R. § 42.4(a)) and in consideration of the Petition, Preliminary Response, and the evidence of record, we determine that the information presented shows that it is more likely than not that Petitioner would prevail in establishing unpatentability of claims 1–3 of the ’201 patent.” slip op. at 2

      “At this stage of the proceedings, neither Petitioner’s nor Patent Owner’s proffered definitions of the level of skill appear appropriate. Petitioner’s proposal requires as little as a bachelor’s degree in organic chemistry and two years of experience as a laboratory technician working on development of molecules with targeted biological activity, and an ambiguous “understanding” of certain processes. Patent Owner’s proposal, other the other hand, requires multiple years of both formal training and actual, practical experience in highly specialized fields that involve detection of optical or radiolabeled compounds and use of molecular imaging techniques such as PET and SPECT. For the purposes of this decision, on the record at this time, we find that a POSA would have had a Ph.D. in chemistry, biochemistry, or a comparable field or an M.D., and at least four years of experience in chemical synthesis of compounds that may be used to target biologically-significant tissues. This definition appears consistent with the level of skill shown in the prior art references of record. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). The parties will have the opportunity to cross-examine Dr. Martin and Dr. VanBrocklin in this proceeding to develop a full record for us to determine the weight that each expert’s testimony should be given. We invite the parties to further brief the definition of a POSA here, and whether we should discount either experts’ testimony due to lack of qualifications.” slip op. at 8

      “c) Analysis On the present record, we find that “low molecular weight” is not limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration all concerns metabolomics and metabolites, and we find no reason that even a vague definition of metabolites applies to the claimed compounds. See Ex. 1002, ¶ 102. Moreover, the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’201 patent fall outside of Patent Owner’s proposed definition is persuasive (see id., ¶ 103), as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). In addition, the opinion stated in the Pomper Declaration that “the term of ‘low molecular weight’ is well accepted in the chemical arts’” and the declarant “recognize[s] that low molecular weight compounds would have a molecular weight of typically form about 50 Daltons to about 1,500 Daltons” is offered by a co-inventor. We, as factfinder, have discretion to weigh the credibility of expert witnesses and to give each item of evidence such weight as appropriate. See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”). In this case, we find that the published references on metabolites do not support the opinion. In re Am. Acad. of Sci. Tech Ctr., 367 F.3d at 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”) The Pomper reference (Ex. 1006) also uses the term “low molecular weight”—without further characterization of the term—and is uninformative as to the meaning of the term. See Ex. 2002, ¶ 60; Ex. 1006, ¶ 12. The table giving the molecular weight of a “selection of compounds disclosed by Pomper” (see Ex. 2002, ¶ 62) is not persuasive in defining “low molecular weight,” as it does not explain how those included were “selected” and does not include molecular weights for all of the examples.7 In addition, Patent Owner’s definition does not appear to apply to all claimed compounds.8 7 At least one of the examples (SRV73) not included in the table appears to have a molecular weight well over “about 1,500 Daltons.” 8 See, e.g., claim 113 of Ex. 1006.

      “The ’201 patent defines “alkyl” as “a straight (i.e., unbranched) or branched chain, acyclic or cyclic hydrocarbon group, or combination thereof” “ that has “the number of carbon atoms designated (i.e., C1–C10 means one to ten carbons, including 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 carbons)” and “[i]n particular embodiments, the term ‘alkyl’ refers to C1-20 inclusive, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 carbons” “unless otherwise stated.” Ex. 1001, 39:44–58. Although substituents at the R1x position in the claims are limited to “C1-6alkyl,” those at position R3x are not. Ex. 1001, Certif. Corr. Patent Owner’s representation that “Jansen I provides ‘the following definitions’ stating that ‘alkyls groups of this invention comprise from 1 to 6 carbon atoms’” is inaccurate. See Prelim. Resp. 19. In fact, Jansen I states: The term “alkyl” by itself or as part of another substituent refers to a fully saturated hydrocarbon of Formula CxH2x+1 wherein x is a number greater than or equal to 1. Generally, alkyl groups of this invention comprise from 1 to 6 carbon atoms. Alkyl groups may be linear or branched and may be substituted as indicated herein. When a subscript is used herein following a carbon atom, the subscript refers to the number of carbon atoms that the named group may contain. Ex. 1007, 22:16–23 (emphasis added). Neither the ’201 patent nor its incorporation by reference of Jansen I would have conveyed to a POSA that the “(CO)alkyl” of the substituent in the R3x position in the claims is intended to comprise from one to six carbon atoms or is limited to any particular length and size. “(C(O)alkyl,” having no number of carbon atoms designated, means” slip op. at 15

      “legal error by construing claim 1” of the ’027 patent “as requiring the slope to always be negative.” Reh’g Req. 4, 6–8. We made no such construction. In fact, we determined that no claim term required express construction, expressly or implicitly. Dec. 7. In arguing that we committed legal error, Petitioner points to statements in Patent Owner’s briefing, see Reh’g Req. 6– 9, but does not identify anything in our Decision that indicates we construed the choosing step of claim 1 as requiring that the DMD slope should always be negative. Consequently, Petitioner’s assertion of legal error is unsupported.” slip op. at 7

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
