“III. LEVEL OF ORDINARY SKILL IN THE ART Petitioner contends a person of ordinary skill in the art (“POSITA”) would have a Ph.D. degree in biological, chemical or biochemical engineering, molecular biology, or biochemistry and at least two years of experience in the field of utilizing or assessing horseshoe crab zymogen proteins (lysate, purified native and/or recombinantly produced) for endotoxin detection and quantitation. More education could substitute for experience to a certain extent, and vice versa. Pet. 22 (citing Ex. 1003 ¶¶48–49). Patent Owner does not dispute Petitioner’s description of a POSITA in its Preliminary Response. Prelim. Resp. 10. 1 In addition to other changes to Title 35, the AIA introduced amendments to 35 U.S.C. § 102. Because Patent Owner concedes that the ’725 application “contains, or contained at any time, a claim to a claimed invention that has an effective filing date on or after March 16, 2013” (Ex. 1022), the AIA version of § 102 applies to the ’109 patent.

“To show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23– 24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in which a POSA would have understood the prior art, or what a POSA would have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)). Thus, the information presented in the Petition, which is limited to the perspective of a 2013 POSITA, does not demonstrate that it is more likely than not that at least 1 of the claims challenged in the Petition is unpatentable for lack of written description.” slip op. at 12

“Nevertheless, we determine that the contrary evidence Petitioner has cited suffices to establish a reasonable likelihood of success at this preliminary stage of the proceeding. In this regard, we also note Dr. Jain’s testimony — currently unrebutted — that an ordinarily skilled artisan would have known, based on Tokunaga’s sequence comparisons of Factor C proteins, that “certain sequence differences between [Limulus polyphemus] and Tachypleus tridentatus were non-conservative (i.e., potentially giving rise to changes in function in terms of enzymatic activity of Factor C).” Ex. 1002 ¶ 94 (citing Ex. 1022, 157). We likewise note Dr. Jain’s testimony that such artisan would have recognized Tokunaga’s conclusion, regarding “immunological and biochemical properties” of Factor C proteins of the two different horseshoe crab species, to be “based on only gross biophysical-biochemical properties” that are not “granular enough” to predict functional properties such as residual activity in presence of specific ions.

See 37 C.F.R. § 42.64(b)(1) (“Any objection to evidence submitted during a preliminary proceeding must be filed within ten business days of the institution of the trial.”); also compare Fed. R. Evid. 801(c) (defining hearsay as a statement, not made at the current trial or hearing, “offer[ed] in evidence to prove the truth of the matter asserted”), with Fed. R. Evid. 801(d)(2) (excluding from hearsay statement offered against an opposing party where statement was made by “a person whom the party authorized to make a statement on the subject” or by a “party’s agent or employee on a matter within the scope of that relationship and while it existed”). Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

“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.

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

“parties, we do not find the merits to be particularly strong on the current record. For example, limitation [1-4] recites, in part, “a locking nut having . . . an external thread on an outside surface of the locking nut.” Ex. 1001, 9:46–47. In alleging obviousness based in part on Orphanos, Petitioner equates the claimed “locking nut” to Orphanos’s collet 230 in a first embodiment of Orphanos, or Orphanos’s collet portion 1052 in a second embodiment of Orphanos. Pet. 37–38. Petitioner acknowledges that the collet and collet portion do not have external threads, but rather are designed to have a snap-fit engagement with the inner sidewall of the baseplate’s central throughbore.

Patent Owner, on the other hand, would have us interpret the claim to require that they be separate structures. Patent Owner raises credible evidence to support its theory. Specifically, Patent Owner directs us to the language of claim 1, which separately recites “a central screw” and “a locking nut.” Prelim. Resp. 51; see Ex. 1001, 9:44–53. Patent Owner further contends, in view of the claim language, that the claimed central post and locking nut are separate and distinct components. According to Patent Owner, however, Lefebvre’s main head and anchor rod portions are parts of a single monolithic anchoring screw. Prelim. Resp. 53–58.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional.

We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46.

“Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006. 2. Conclusion: PGR Eligibility For the foregoing reasons, and based on the record before us, we determine that Petitioner has not demonstrated that it is more likely than not that the ’202 patent has, or had, at least one claim having an effective filing date on or after March 16, 2013. Accordingly, we determine that the ’202 patent is entitled to the filing date of the ’634 application (October 18, 2006), and, thus, the ’202 patent is not eligible for post-grant review.” slip op. at 18

“Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals. These two facts provide together a proper reason to limit the claims in this way.”); Phillips v. AWH Corp., 415 F.3d 1303, 1312–1317 (Fed. Cir. 2005) (en banc) (“[T]he specification may reveal an intentional disclaimer, or disavowal, of claim scope by the inventor.

“Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim. Resp. 13 (noting that Petitioner does not identify other limitations in the challenged claims “allegedly lacking support in the ’202 patent family’s applications dating back to U.S. App. No. 11/550,634, filed on October 18, 2006”). Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

“We note that the identification of a Ph.D. as an example of “more formal education” creates a vast range of education relative to a bachelor’s degree. Thus, we treat the identification of a Ph.D. just as it is—an example—and not a requirement. In this case, “more formal education” can be satisfied by a level of education less than a Ph.D (but greater than a bachelor’s degree).

“patent describes that “angular position transducer 78 is placed on top of swing leg pivot shaft 24” and that “pivot shaft 24 is rotationally fixed to the connector plate and duplicates the angular movements of swing leg 20 about the pivot shaft.” Ex. 1001, 12:15–16, 12:20–22, Figs. 5, 7. The ’723 patent also describes that “[a]ngular position transducer 78 is mounted inside . . . protective can 90 . . . which is bolted to hinge bracket 28 via an upright holding arm 92” and that “trigger pin 94 projects upwardly from the top surface of pivot shaft 24 and cooperates with angular position transducer 78 to generate an angular position signal.” Id. at 12:28–33, Fig. 5. These descriptions expressly convey that angular position transducer 78 is on pivot shaft 24 and mounted inside protective can 90 that is bolted to hinge bracket 28. Id. at 12:15–16, 12:20–22, 12:28–30, Figs. 5, 7; see also Prelim. Resp. 17 (describing the same embodiment shown in Figs. 5 and 7). According to Petitioner, the ’723 patent describes the pivot shaft as part of the hinge bracket, not the modular frame or swing leg. Pet. 109–110 (citing Ex. 1001, 7:42–46, 12:17–22). On the preliminary record, we agree because the cited portions of the Specification describe that a “hinge bracket is interposed between each swing leg and an associated surface of the bolsters and includes a fixed, upright pivot shaft that pivotally engages the swing leg for pivotal movements” and “pivot shaft 24 is rotationally fixed to the connector plate.” Ex. 1001, 7:42–45, 12:20–21. We also agree that “even if one were to find that the hinge bracket is part of either the modular frame or swing leg (contrary to the claims and specification treating these all as separate components), the specification would only provide written description for one of the claimed alternatives.” Pet. 110 (citing Ex. 1002 ¶ 199).” slip op. at 19
