      “Electromedizinishe Gerӓte GmbH, IPR2019-01469, Paper 6 at 8–10 (Feb. 13, 2020) (“Advanced Bionics”) (precedential), the Board addresses § 325(d) applying a “two-part framework.” In the first part of the framework, we ask whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments 8 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. 22 previously were presented to the Office. Advanced Bionics at 8. Factors (a), (b), and (d) of Becton, Dickinson come into play under this first part of the framework. Id. at 8–10. If either condition of the framework’s first part is met (e.g., substantially the same art is presented), we move to part two of the framework, asking “whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of [the] challenged claims.” Id. at 8. Factors (c), (e), and (f) of Becton, Dickinson fall within part two of the framework. Id. at 10 (“[F]actors (c), (e), and (f) relate to whether the petitioner has demonstrated material error by the Office.”). Only if the same or substantially the same art or arguments were previously presented to the Office do we then consider whether petitioner has demonstrated error. Advanced Bionics at 8–10. “If the petitioner fails to show that the Office erred, the Director may exercise his discretion not to institute inter partes review.” Id. at 8–9. “At bottom, this [§ 325(d)] framework reflects a commitment to defer to previous Office evaluations of the evidence of record unless material error is shown.” Id. at 9 (“If reasonable minds can disagree regarding the purported treatment of the art or arguments, it cannot be said that the Office erred in a manner material to patentability.”). B.” slip op. at 22

      “Patent Owner does not dispute Petitioner’s proposed definition, but states that the person of ordinary skill in the art would “[t]ypically” . . . have had an M.D. or a Ph.D. in immunology, biochemistry, cell biology, molecular biology, or a related discipline, with at least two years of experience in conducting laboratory research on chimeric T cell receptors.” Prelim. Resp. 44 (citing Ex. 2001 ¶ 20). According to Patent Owner, the ordinarily skilled artisan “would have had knowledge of the scientific literature and have skills relating to chimeric T cell receptors and methods of using such receptors” and “may have worked as part of a multidisciplinary team” and been able to draw on the specialized skills of, for example, an immunologist, and/or a clinical oncologist. See id. at 43–44. Considering the record before us, both parties present reasonable definitions of one of ordinary skill in the art. For the purpose of this proceeding, we consider one of ordinary skill in the art as having had an M.D. or a Ph.D. in immunology, biochemistry, cell biology, molecular biology, or a related discipline, with at least two years of experience in conducting laboratory research on chimeric T cell receptors and/or the use of CAR-T immunotherapy. Consistent with Patent Owner’s proposed definition, the ordinarily skilled artisan may have worked as part of a 20 multidisciplinary team and been able to draw on the specialized skills of, for example, an immunologist, and/or a clinical oncologist.” slip op. at 20

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble not limitingDecided for patent owner

      “We do not find Petitioner’s argument persuasive for the reasons set forth on pages 34–40 of the Preliminary Response. Most particularly, we note that the phrase “[a] chimeric antigen receptor (CAR)” occurs solely in the preamble of independent claim 24. Terms in a preamble, however, are not generally construed as limiting. See Allen Eng’g Corp. v. Bartell Indus., Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). More specifically, “when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention,” the preamble is not considered a limitation. Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 809 (Fed. Cir. 2002). In the present case, we find it plausible—if not likely—that the Examiner gave no weight to the terms in the preamble of claim 24 such that the remaining language did not expressly or implicitly require either a 32 transmembrane domain, or a “T-cell activation moiety” specific to CAR constructs. The Examiner appears to have recognized, however, that CAR constructs differ from Kalled’s antibodies at least in having a transmembrane domain as expressly recited in claims 29 and 30. See Ex. 2005, 605, 745–749 (allowing amended claims). This view is underscored by the Examiner’s decision not to reject claims 34 and 38 as anticipated by Kalled. See Ex. 2005, 604. Notably, claims 34 and 38 recite SEQ ID Nos 4–12, each of which encodes a complete CAR construct and, thus, implicitly includes a transmembrane domain. See id. at 589 (claiming a CAR comprising the amino acid sequence of SEQ ID Nos: 4–12 (claim 34) or a nucleic acid encoding the same (claim 38)); Ex. 1001, 9:49–53; Ex. 2001 ¶ 92.12” slip op. at 32

      “The test for written description support is “whether the disclosure of the application relied upon reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date” based on an “objective inquiry into the four corners of the specification.” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). If this test fails, the application is not entitled to the benefit of the earlier filing date. The written description requirement is satisfied when the specification “set[s] forth enough detail to allow a person of ordinary skill in the art to understand what is claimed and to recognize that the inventor invented what is claimed.” University of Rochester v. G.D. Searle & Co., Inc., 358 F.3d 916, 928 (Fed. Cir. 2004). The specification does not have to provide exact or verbatim textual support for the claimed subject matter at issue. Fujikawa v. Wattanasin, 93 F.3d 1559, 1570 (Fed. Cir. 1996). The Federal Circuit has clarified that [a]lthough [the applicant] does not have to describe exactly the subject matter claimed, . . . the description must clearly allow persons of ordinary skill in the art to recognize that [he or she] invented what is claimed . . . . The test for sufficiency of support . . . is whether the disclosure of the application relied upon “reasonably conveys to the artisan that the inventor had possession at that time of the later claimed subject matter.” Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991) (citations omitted). Moreover, “the written description requirement does not demand either examples or an actual reduction to practice.” Capon v.

      “Petitioner proposes that one of ordinary skill in the art would have had “an M.D. degree or a Ph.D. degree in biochemistry, pharmacology, nutrition chemistry, exercise physiology, or kinesiology, and at least two years of post-doctoral research or clinical experience with physiology, biochemistry, exercise science, or dietary supplements and formulation.” Pet. 16 (citing Ex. 1003 ¶ 21). Patent Owner does not challenge this definition at this time. Prelim. Resp. 7. For purposes of this decision, we apply Petitioner’s proposed definition as it is consistent with the level of skill presented in the ’555 patent and applied art. We also note that the level of ordinary skill in the art at the time of the invention may be reflected in the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus.

      “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. Prelim. Resp. 30. Moreover, PCT1 discloses a working example where three test subjects were given a dose in the range Petitioner alleges would be lethal, with no ill result. Id., citing Ex. 1008 ¶ 106. Dr. Volek’s failure to address this discrepancy, or to provide alternate sources to explain why his conclusion is nonetheless correct, merits his brief testimony on this issue be assigned little probative” slip op. at 20

      “G. Claim Construction In a post-grant review, we apply the same claim construction standard as would be used by a district court to construe a claim in a civil action involving the validity or infringement of a patent. 37 C.F.R. § 42.200(b) (2020). Under that standard, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record. Id.; Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc); Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365–66 (Fed. Cir. 2012). Pet. 23–24. Patent Owner does not propose a construction for “inorganic nitrate.” Prelim Resp. 8–9. For purposes of determining whether to institute trial of the challenged claims, we determine it is not necessary to construe “inorganic nitrate.” Vivid Techs., Inc. v. Am.

      “Petitioner’s proposed construction of the term “longer.” See supra, Section II.A (“[L]onger” lasting means “the longer duration of efficacy of an animal-protein-free botulinum toxin composition when compared to an animal-protein-containing botulinum toxin composition that is dosed at the same or comparable amount and administered in the same manner (e.g., by injection) to the same or comparable location(s).” (emphasis added)). Although Petitioner is correct in pointing out that Ruegg compared the effect of “5.0 U/kg of either RT003 or BOTOX®” (Pet. 35; Ex. 1004, Figure 1), 13 Petitioner has not sufficiently shown that 5.0 U/kg of RT003 is the same or comparable amount as 5.0 U/kg of BOTOX. Indeed, BOTOX Label explains that one unit (U) of BOTOX “corresponds to the calculated median intraperitoneal lethal dose (LD50) in mice.” Ex. 1007, 548. BOTOX Label emphasizes that the method for performing the assay is specific to BOTOX. Id. “Due to specific details of this assay such as the vehicle, dilution scheme and laboratory protocols for the various mouse LD50 assays,” it warns, units of biological activity of BOTOX “cannot be compared to nor converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method.” Id.” slip op. at 13

      “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.

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.

      “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.
