      “review, “the Director may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.”3 Our § 325(d) analysis employs a two-prong framework: (1) whether the arguments presented in the petition are the same or substantially the same as those previously presented to the Office; and (2) if so, whether the petitioner has demonstrated a material error by the Office in its prior consideration of those arguments.

Advanced Bionics, 9. These non-exclusive factors include: (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Becton, Dickinson, 17–18 (formatting added). “If, after review of factors (a), (b), and (d), it is determined that the same or substantially the same art or arguments previously were presented to the Office, then factors (c), (e), and (f) relate to whether the petitioner has demonstrated a material error by the Office.” Advanced Bionics, 10.” slip op. at 10

      “Further, although Petitioner contends that BK Medical’s needle guide “maintains and stabilizes” the needle position, they provide no explanation as to how it does so and do not appear to account for forces that would move the position of the needle during insertion. Petitioner cites to testimony from their declarant, Dr. Yun, to provide support for this argument; however, Dr. Yun’s testimony is essentially a verbatim repetition of Petitioner’s argument without a discussion of how BK Medical’s needle guide provides such stability. Compare Pet. 59–60 with Ex. 1003 ¶ 107. Thus, we accord little weight to Dr. Yun’s testimony on this topic. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Xerox Corp. et al., v.

Prelim. Resp. 21–32; see Apple Inc. v.

Mar. 20, 2020) (precedential). Because we deny the petition under 35 U.S.C. § 325(d), this argument is moot. Further, we note that Petitioner has filed a stipulation under Sotera Wireless, Inc. v.

We determine that neither of the two limitations identified by Petitioner requires an express construction for purposes of this Decision. It bears mentioning, however, that the ’357 patent states that “[t]he insertional enzyme can be a transposase.” Ex. 1001, 3:47–48. There is no dispute that Grunenwald discloses the use of a transposase and, thus, an insertional enzyme complex. See Pet. 16 (citing Ex. 1003 ¶¶ 17, 93–94, 162); Prelim. Resp. 13 (“Grunenwald further defines ‘transposase’ to mean ‘an enzyme that is capable of forming a functional complex . . . and catalyzing insertion or transposition of the transposon end-containing composition into the double-stranded target DNA with which it is incubated in an in vitro transposition reaction.” (citing Ex. 1003 ¶ 93)).” slip op. at 6

      “Petitioner “has the burden from the outset to show with particularity why the patent it challenges is unpatentable.” Harmonic, Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016); see also SAS Inst., Inc. v. Iancu, 138 S.Ct. 1348, 1355 (2018) (“in an inter partes review, the petitioner is the master of its complaint”). A petition for inter partes review must identify how the challenged claims are unpatentable, and must specify where each element of the claim is found in the relied-upon prior art. 37 C.F.R. § 42.104(b); see also 35 U.S.C. § 312(a)(3) (a petition must identify, “with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim”). A petition must also include “a detailed explanation of the significance of the evidence including material facts, and the governing laws, rules, and precedent.” 37 C.F.R. § 42.22(a)(2). What is missing from both the Petition and the supporting testimony is an adequate explanation of how or why a POSA would have understood that Jung teaches the isolation of a botulinum toxin type A macro complex in particular, when Jung is silent as to the form of the toxin being produced. In this case, it is not enough to simply cite evidence; an explanation of the significance of that evidence is necessary. Based on our review of the record, we find that there is insufficient explanation and insufficient supporting evidence that Jung teaches isolating a botulinum toxin type A macro complex. Petitioner’s statements, and Dr. Bates’s testimony, that Jung teaches isolating a botulinum toxin, and that botulinum toxins “naturally comprise[] a complex with a variety of non-toxic proteins bound thereto” that can be intermediate, large, or macro in size, are conclusory because they do not explain why the form of toxin ultimately isolated in Jung is a macro complex. Therefore, Petitioner does not sufficiently show that the combination of Jung and Ton discloses “[a] method of isolating a botulinum toxin type A macro complex from a botulinum containing solution” or “separating the botulinum toxin type A macro complex from the cation exchange chromatography medium” as required by claim 1 of the ’598 patent.” slip op. at 13

      “To support a conclusion of obviousness when combining the teachings of multiple references, an articulated reason with some rational underpinning to combine the known elements in the fashion claimed must be provided. See KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007); see also In re Magnum Oil Tools, Int’l, Ltd., 829 F.3d 1364, 1381 (Fed.

Here, the Petition lacks an adequate explanation as to why a POSA reading Kim ’741 would have looked to Jung for its teachings regarding anion exchange chromatography, and how a POSA would have combined the teachings of Kim ’741 and Jung in the manner claimed. Because we are not persuaded that Petitioner sufficiently establishes a motivation to combine Kim ’741 and Jung with respect to the anion exchange chromatography limitation of claim 1, we are not persuaded that Petitioner’s alternative assertion of Jung for this limitation warrants reconsideration of the prior art and arguments previously considered by the Office. Accordingly, we find that the Examiner’s failure to consider Jung in combination with Kim ’741 with respect to the anion exchange chromatography limitation of claim 1 is not an error that weighs in favor of institution.” slip op. at 29

      “ApoE4+ patient with AD using tramiprosate over the Caltagirone reference, which disclosed treatment of ApoE4+ “all-comers” (containing at least one ApoE4 allele, either heterozygous or homozygous) with tramiprosate. See, e.g., Ex. 1002, 204–208. When Patent Owner responded to the Examiner by highlighting data (i.e., Figure 8 of the specification giving rise to the ’029 patent) showing a notable increase in cognitive function in patients with two ApoE4 alleles (homozygous) who were administered tramiprosate as compared to the ApoE4 “all-comers” (mixed homozygous/heterozygous population), the Examiner suggested narrowing the pending claims to treatment of ApoE4 homozygotes. Ex. 1002, 342. Patent Owner submitted amended claims requiring selection of patients for treatment who were homozygous for ApoE4, and argued: The presently amended claims . . . select only ApoE4 homozygotes for treatment with tramiprosate or a prodrug thereof, necessarily omitting ApoE4 heterozygotes from such treatment. . . . Caltagirone fails to teach or suggest a patient selection strategy that would limit tramiprosate treatment to patients having two ApoE4 alleles and, in fact, teaches away from such selection. Kong fails to contradict or overcome these deficiencies in Caltagirone. Kong does not refer to any patient selection strategy, much less one that would limit tramiprosate prodrug treatment to ApoE4 homozygotes. The Office's reliance on Kong is solely for its teaching of a tramiprosate prodrug. Thus, the combination of Caltagirone and Kong, taken under the Office’s interpretation, suggests treatment of all ApoE4+ patients with a prodrug of tramiprosate. This falls far short of suggesting the presently claimed patient selection and treatment strategy which selects only ApoE4 homozygotes for treatment and does not treat ApoE4 heterozygotes.

      “Petitioner asserts that a person of ordinary skill in the art (“skilled artisan”) at the time of the invention would have had at least an M.D. or Ph.D. degree in a biomedical science or equivalent field. They would also have several years of clinical experience treating and/or conducting clinical trials of drugs for AD patients, or professional experience working in clinical trial design and execution related to drugs for AD or supervising such work. Pet. 19 (citing Ex. 1003 ¶¶ 52–53). Patent Owner does not contest the characterization offered by Petitioner. Prelim. Resp. 14–15. For purposes of this Decision, we adopt Petitioner’s characterization as it is consistent with the level of skill in the art at the time of the invention as reflected by the ’029 patent and the cited prior art.

      “Babic ascertained that “different effects of a drug could be observed in different subpopulations of patients based on ApoE4 carrier status”” and that “drug effects in homozygous carriers could be greater than those in the heterozygous carriers and non-carriers who did not respond to the drug.” Ex. 1003 ¶ 107. As stated, this testimony does not support Petitioner’s contention that an ordinary artisan would have been motivated “to select homozygous ApoE4 carriers for treatment with any drug for which response has been correlated to ApoE4 carrier status.” See Pet. 41 (emphasis added). In particular, we find an insufficient factual basis for Petitioner’s contention that results obtained for galantamine, an acetylcholinesterase inhibitor (Ex. 1003 ¶ 105) would have motivated an ordinary artisan to replace the galantamine taught in Babic with tramiprosate (homotaurine), a GABA receptor agonist that works by a different mechanism (Ex. 1007, 582). We have also considered Dr. Ruffalo’s testimony that the ordinary artisan would have been motivated to replace Babic’s galantamine with tramiprosate as taught in Caltagirone or Val-APS as taught in Kong. Ex. 1003 ¶¶ 276–277. Dr. Ruffalo posits that Babic’s disclosures would have motivated the ordinary artisan to analyze Caltagirone’s data to ascertain if tramiprosate is more effective in homozygotes, and to replace galantamine with tramiprosate or Val-APS as taught in Kong because of their improved safety profiles as compared to galantamine, and because the replacement drugs target the underlying disease and not symptom amelioration as does galantamine. Id. Dr. Ruffalo also posits that the prior art would have imparted the following knowledge to the ordinary artisan: because the effect of tramiprosate was dependent on the required ApoE4 allele, homozygotes having the highest number of ApoE4 allele copies would derive, at the very least, as much benefit as from the drug as the heterozygotes having only one copy of the allele, and most likely the homozygotes would have the greatest therapeutic response to tramiprosate since they have the maximum number of copies of the required allele. Having done this simple assessment, A POSA would conclude that tramiprosate would be expected to exhibit a greater therapeutic effect in homozygotes and thus would have been motivated to treat homozygotes with tramiprosate, including in an oral dosage form as taught by Aisen. Id. Dr. Ruffalo further posits that the skilled artisan would have had a reasonable expectation of success in administering tramiprosate to treat homozygous ApoE4 patients because they “would almost certainly have the greatest response to the drug.” Id. ¶ 286. Patent Owner argues that the Examiner previously examined the issue of whether ApoE4 genotypes in treatment decisions should be considered during prosecution, with respect to Caltagirone, where ApoE4 genotypes were included, and Sleegers (Ex. 1002, 685, 1137), where studies led away from such inclusion. Prelim. Resp. 30–31. We find Sleegers’ disclosure” slip op. at 29

      “In addressing the level of ordinary skill in the art, Petitioner contends that: A POSA is a person skilled in the art of administering CAR T-cell therapies. The person would possess a relatively high level of skill and have at least an MD, together with several years of experience in administering CAR T-cell therapies. The person would also have experience designing CARs. The POSA would have knowledge of the scientific literature pertaining to immunology, including CARs and methods for utilizing CARs before the priority date. A POSA would also be knowledgeable about laboratory techniques related to engineering and testing the function of CAR T-cells. A POSA would also be knowledgeable about designing clinical trials, including selecting dose ranges, that evaluate CAR T-cell therapies. Pet. 10. Patent Owner does not presently contest this definition. Although Petitioner’s definition generally comports with our understanding of the high level of skill in the art, we are not persuaded all of the asserted qualifications must be embodied in a single person. For example, it seems unduly limiting to require that the person of ordinary skill in the art have “at least an MD” degree, and “be knowledgeable about laboratory techniques related to engineering and testing the function of CAR T-cells,” as Petitioner suggests. Accordingly, we provisionally adopt Petitioner’s definition with the caveat that the asserted qualifications may be shared among multiple individuals working as part of a multidisciplinary team. C.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notNot reached

      “Patent Owner points out that the structure of independent claim 1 here is similar to those addressed in Eli Lilly. Prelim. Resp. 18. And, as in Eli Lilly, the Specification of the ’140 patent underscores the centrality of the method recited in the preamble. Id. (citing Ex. 1001, codes (54), (57), 1:55– 57). Unlike in Eli Lilly, however, the body of independent claim 1 does not recite merely “an effective amount” but “an anti-tumor effective amount” of the composition administered. Petitioner argues that whereas the preambles in Eli Lilly “provide the only metric by which one practicing the claim could determine whether the amount administered is an ‘effective amount,’” the term “anti-tumor effective amount” in independent claim 1 “is well-defined by the specification and provides sufficient guidance for determining effectiveness.” Prelim. Reply 3 (citing Eli Lilly at 1342). On balance, Petitioner appears to have the better argument. Nonetheless, even if we were to construe the treatment language of the preamble to mean “reducing the frequency or severity of at least one sign or symptom of cancer” as Patent Owner proposes, this definition is coextensive with, if not subsumed by, the term “anti-tumor effective amount,” discussed below. As such, the outcome of this proceeding does not turn on whether the preamble is limiting.” slip op. at 17

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “As we understand it response, Patent Owner does not appear to contest that “anti-tumor effect” can comprise a decrease in the number of tumor cells, but argues that the claim term requires “a palpable therapeutic effect,” which is more than “just the death of a single cancer cell or handful of cells.” Prelim. Resp. 19–23; Prelim. Sur-reply 4–5. In support, Patent Owner points to the ’140 patent’s express definition of “[a]n ‘effective amount’” as meaning “an amount which provides a therapeutic or prophylactic benefit.” Pet. 20 (citing Ex. 1001, 13:53–54). Relatedly, we note that the Specification also teaches that a “‘therapeutically effective amount’ includes that amount of a compound that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the signs or symptoms of the disorder or disease being treated.” Ex. 1001, 18:12–15. Patent Owner further contends that “[t]he specification teaches that ‘an antitumor effective amount’ is an amount to be administered that is “determined by a physician” as part of determining ‘[t]he optimal dosage and treatment regime for a particular patient . . . by monitoring the patient for signs of disease and adjusting the treatment accordingly.’” Prelim. Resp. 22 (citing Ex. 1001, 37:53–38:5). Considering the argument and evidence of record, we agree with Patent Owner that one of ordinary skill in the art would understand an “anti- tumor effective amount” as used in claim 1 to require more than the killing of a single tumor cell. Accordingly, we provisionally construe “anti-tumor effective amount” as any amount of CAR T-cells administered to a patient in need of cancer treatment that reduces the frequency or severity of at least one clinically relevant sign or symptom of the disease. To the extent this functional limitation is satisfied, claim 2 indicates that an “anti-tumor effective amount” may be limited to between 104 to 109 CAR T-cells/kg body weight. At this stage of the proceeding, no other term requires construction.” slip op. at 19

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “reasonable expectation of success in light of the unpredictability of cancer therapy and the “uninspiring” results and failures of earlier CAR-T clinical trials. Prelim. Resp. 23–28 (citing e.g., Ex. 2037, 1036; Ex. 2010, 1824– 1825; Ex. 2032, 1250–1251). In support, Patent Owner points to OSI Pharms. as “directly on-point.” Id. at 24 (citing OSI Pharms., LLC v. Apotex Inc., 939 F.3d 1375 (Fed. Cir. 2019)). The claims at issue in OSI Pharms., were structurally similar to those at issue here and directed to a method of treating non-small cell lung cancer (“NSCLC”) in a mammal using a therapeutically effective amount of erlotinib, which had previously been shown to inhibit the epidermal growth factor receptor (“EGFR”) in vitro. 939 F.3d at 1378–79. The court stated: Cancer treatment is highly unpredictable. Even though the EGFR was identified in some cancers as a drug target, the in vitro (i.e., in a test tube) effectiveness of a drug in inhibiting the EGFR turned out to be a poor proxy for how effective that drug actually was in treating cancer in vivo (i.e., in the body). Numerous EGFR inhibitors that showed promising in vitro activity failed for a variety of reasons. Id. at 1377; see also id. at 1386 (“1,630 other new drug compounds that, like erlotinib, targeted NSCLC and were studied in Phase II trials. The failure rate for these compounds was 99.5%”). Against this backdrop, the court reversed the Board over its unsupported reading of the two cited references, finding that: the asserted references do not disclose any data or other information about erlotinib’s efficacy in treating NSCLC. The record does not contain any clinical (human) data or preclinical (animal) data. It does not even include in vitro (test tube) data regarding erlotinib’s effect on NSCLC. Id. at 1384. Considering the promising in vitro data presented in Campana and Jensen, Petitioner here has a somewhat better position than the Appellees in OSI Pharms. At core, Grounds 1 and 2, require us to find a reasonable expectation of success in treating a human cancer based on in vitro experiments, the mere existence of a clinical trial, and absent any of the “clinical (human) data or preclinical (animal) data,” highlighted by the court. See id. Considering the inherent unpredictability of the field and the history of failures of similar technology documented by Patent Owner, we do not find Petitioner’s arguments persuasive. As such, Petitioner has not demonstrated a reasonable likelihood of success in proving that any claim of the ’140 patent is unpatentable under Grounds 1 and 2.” slip op. at 40
