      “V. CONCLUSION Petitioner has, at this stage, established that it will more likely than not prevail in showing that at least one of the challenged claims is unpatentable. This determination is, however, based on a preliminary record and is not final on any issues of patentability. We will make a final determination on the patentability of the challenged claims, as necessary and applying the preponderance of the evidence standard, based on a fully developed record through trial. VI. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 324(a) post grant review of claims 1–4 of the ’233 patent is hereby instituted on the grounds set forth in the Petition, commencing on the entry date of this Order, and pursuant to 35 U.S.C. § 324(d) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial; and” slip op. at 40

For the purposes of this decision, on the record at this time, we find that Petitioner’s definition appears consistent with the level of skill shown in the prior art references of record, and apply it herein. See Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007).

      “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 from 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 (“[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.”) US-121, of which Dr. Pomper is lead inventor, 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. 1006, ¶ 12. In addition, Patent Owner’s definition does not appear to apply to all compounds claimed in US-121.5” slip op. at 11

      “limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, 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). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20. We are persuaded by the testimony of Dr. Zeglis, Petitioner’s declarant, that compounds weighing over 1500 Da may share those same behaviors, along with certain identified B moieties disclosed as embodiments. See Ex. 1003 ¶ 83.” slip op. at 10

      “The Petition includes detailed arguments that map the limitations of the challenged claims to specific disclosures in Yu (Sample 1). Id. at 50–62. The Petition also maps adequately the limitations of the challenged claims to specific disclosures in Stewart (Example 2). Id. at 62–66. For example, Petitioner shows sufficiently that Yu (Example 1) coextrudes “a multilayered polymeric film,” that is, a “sheet,” arranged in the hard-soft-hard-soft-hard, five-layer configuration required by claim 11. Pet. 50–51; Ex. 1002 ¶¶ 124, 126–128; Ex. 1012 ¶¶ 63, 78, 92. Petitioner also shows sufficiently that the hard layers in that configuration of Yu (Example 1) are “hard” and the hard layers are “hard” within the meaning of claim 11. Pet. 53; Ex. 1002 ¶ 131; Ex. 1012 ¶ 78. In other words, Petitioner shows sufficiently, on this record, that Yu (Example 1) anticipates claim 11. Based on the information presented, we find that Petitioner shows sufficiently, for purposes of trial institution, that at least one challenged claim of the ’263 patent is anticipated by Yu (Sample 1).” slip op. at 12

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “That prior art disclosure of elastomeric materials for use as the outer layers in an unclaimed and disfavored soft-hard-soft layer configuration does not convey, with reasonable clarity, that the inventors had possession of the claimed subject matter, in which the elastomeric material forms the inner layer of a polymeric sheet in a hard-soft-hard layer configuration. See id. ¶¶ 7, 33–35, 109–110. Even if the hardness limitation of the challenged claims would have been obvious from the relied-upon disclosure of the ’176 application (Ex. 2001 ¶ 109), that circumstance is insufficient to establish written description support. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008) (quotations omitted); see Pet. 21 (quoting that precedent). Accordingly, we agree with Petitioner that the invention that Patent Owner seeks to protect in the ’263 patent does not appear to be “part of the invention” described in the ’176 application. Pet. 40; see Ex. 2001 ¶ 109 (describing elastomeric materials, having the specified hardness, only in the context of an unclaimed prior art soft-hard-soft embodiment). On this record, we preliminarily agree with Petitioner that the earliest effective filing date to which the ’263 patent appears to be entitled is December 18, 2019, namely, the filing date of the ’256 application, from which the ’263 patent issued. Ex. 1001, codes (21), (22). Patent Owner may contest this issue in a timely response to the Petition.” slip op. at 9

      “The parties disagree about whether the ordinarily skilled artisan would have had specific “experience with dental appliances or access to individuals with such experience.” Prelim. Resp. 17; see Pet. 14–15 n.1 (disagreeing with that proposition). Neither party explains why a resolution of that Stat. 284 (September 16, 2011), includes revisions to Section 102(a) that became effective on March 16, 2013. For reasons explained in this Decision, on this record it appears Petitioner is correct that the challenged claims are entitled to an effective filing date no earlier than December 18, 2019 and, therefore, the AIA provisions apply in this proceeding. See Pet. 22, 39–40; Ex. 1001, code (60). 2 WO 20010/043419 A1, published Apr. 22, 2010, with English Translation (Ex. 1015). 3 We take notice that the first and second grounds identified in the Petition assert anticipation based on the same prior art disclosure. 4 US Pub. 2004/0224283 A1, published Nov. 11, 2004 (Ex. 1008). dispute is necessary to this Decision to institute review. See, e.g., Prelim. Resp. 17 n.2 (“even under Petitioner’s proposed definition, the Petition fails to show a reasonable likelihood that any claim is unpatentable”); Pet. 14–15 & n.1 (arguing about the issue without explaining how a resolution of the dispute would change the outcome of the decision on institution). If either party believes that the difference in level of skill would have a material effect on the analysis of the patentability of the challenged claims, that issue should be specifically addressed in briefing during the trial. We will resolve that dispute only to the extent necessary in any final written decision. Based on the information presented, we find that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 6

Patent Owner discusses the terms “layer” and “inner.” Prelim. Resp. 19–22. Taking account of the information presented, we determine that no claim term requires express construction for purposes of deciding whether to institute review.

      “Ex. 1006, 1 (citations omitted). Accordingly, when considering the ’507 patent’s purpose, the type of problems encountered in the art, and prior art solutions to those problems, it is clear that with respect to levodopa/carbidopa treatments for Parkinson’s Disease, the pharmaceutical formulation and its resulting pharmacokinetics and patient experience are intertwined, thus supporting a requirement that a person of ordinary skill in the art have knowledge or experience in each of these areas. See, e.g., Indivior Inc. v. Dr. Reddy’s Labs., S.A., 930 F.3d 1325, 1345 (Fed. Cir. 2019) (finding no clear error in district court’s compromise measure of level of ordinary skill in the art as a team comprising different skill sets). In view of the above considerations, we preliminarily find that a person of ordinary skill in the art would be a member of a team that includes person(s) with (a) a Ph.D. in a field related to the development of pharmaceuticals (for example, pharmacology, pharmacokinetics, pharmaceutics, pharmaceutical chemistry, organic chemistry, biochemistry, molecular biology, medicinal chemistry, formulation development, or a related field), or equivalent degree, and 2–4 years of experience in the analysis of pharmacokinetic data, pharmaceutical formulation development, and/or drug discovery or development, or a B.S. or M.S. degree in a field related to the development of pharmaceuticals, or equivalent degree, and 4–6 years of experience in the analysis of pharmacokinetic data, pharmaceutical formulation development, and/or drug discovery or development, and (b) a medical degree or equivalent degree with experience in treating patients with Parkinson’s disease. In subsequent briefing, should the parties propose any differences from the team approach articulated above, they should support their proposal and address the impact, if any, of the differences on the pertinent disputes in this proceeding.

      “Determining whether a patent is subject to the first-inventor-to-file provisions of the AIA, and therefore eligible for post-grant review, is straightforward when the patentee filed the application from which the patent issued before March 16, 2013, or when the patentee filed the application on or after March 16, 2013, without any priority claim. The determination is more complex, however, for a patent that issues from a “transition application,” that is, an application filed on or after March 16, 2013, that claims the benefit of an earlier filing date. See MPEP § 2159.04 (9th ed. Rev. 10.2019, June 2020). Entitlement to the benefit of an earlier date under 35 U.S.C. §§ 119, 120, 121, or 365 is premised on disclosure of the claimed invention “in the manner provided by § 112(a) (other than the requirement to disclose the best mode)” in the earlier application. See 35 U.S.C. §§ 119(e), 120. Thus, a patent that issues from a transition application is not available for post-grant review if the claimed subject matter complies with the written description and enablement requirements of § 112(a) for an ancestor application filed prior to March 16, 2013.” slip op. at 9

      “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.

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.

      “The Fintiv factors “relate to whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Fintiv, IPR2020-00019, Paper 11 at 6. A stay of parallel litigation pending resolution of a Board proceeding “allays concerns about inefficiency and duplication of efforts.” Id. That the E.D.N.Y. case was stayed “at its earliest stage,” however, does not “allay[] concerns about inefficiency and duplication of efforts” in view of the 1220 investigation. Additionally, the E.D.N.Y. case was stayed “pending completion” of the 1220 investigation, not because of any Board proceeding. Ex. 3002, 1. With dates set in the 1220 investigation for the ALJ’s initial determination and the ITC’s final determination, a stay seems highly unlikely, especially with the initial determination date about a week away. Hence, factor (1) weighs against institution. See Fitbit, Inc. v. Koninklijke Philips N.V., IPR2020-00771, Paper 14 at 16–17 (PTAB Oct. 19, 2020).” slip op. at 18

      “essentially the same argument about the ’557 patent’s effective filing date for its challenge based on Nakamura-959 and Nakamura-949 as for its invalidity defense based on insufficient written-description support for claim 1.

As we understand the arguments, resolving the ’557 patent’s effective filing date does not require interpreting any part of § 1.57. See Pet. 12–21; Prelim. Resp. 29–31. Instead, the issue turns on whether the ’154 application supports claim 1 according to § 112’s first paragraph. See Pet. 12–21; Prelim. Resp. 29–31. Also, the challenges based on Tanda present a similar issue whether the ’447 provisional supports claim 1 according to § 112’s first paragraph. See Pet. 12–21, 61; Prelim. Resp. 29–31, 36–37. “[T]he test for sufficiency 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.” Ariad Pharm., Inc. v.

      “temperature change within a short period of time, in conjunction with Moslehi’s RF chuck that has low thermal mass, to teach “the thermal mass of the substrate holder is selected for a predetermined temperature change within a specific interval of time during processing,” as claimed. Id. at 20– 22 (citing Ex. 1002, 6:18–62, 7:19–30; Ex. 1003, 4:45–48, 4:55–57, 10:7–9, 11:58–60; Ex. 1008 ¶¶ 73, 74). Lam also provides a rationale to combine the teachings of Kadomura’s embodiment 1 with those of Moslehi. Id. at 40–42. Flamm raises several arguments in response. First, Flamm contends that, in related Case IPR2015-01759, the Board was not persuaded by Lam’s approach of parsing phrases recited in independent claim 13 that are “interdependent” and addressing those phrases individually. PO Resp. 4 (citing Ex. 2001, 17). Flamm argues that, even though in this case Lam parses “the thermal mass of the substrate holder is selected for a predetermined temperature change within a specific interval of time during processing” into two elements instead of three elements, this should not change the Board’s initial admonishment—namely, “[t]he claim language requires that these phrases are interdependent, and cannot be parsed into separate elements met individually.” Id. at 4 (emphasis added). Second, Flamm contends that Kadomura’s predetermined temperature change and time interval are not interdependent, as is required by independent claim 13. Id. at 5. Instead, Flamm argues that, because Kadomura’s time interval is a function of the time required to exhaust the first gas prior to introducing and stabilizing the second gas, this time interval is divorced completely from the predetermined temperature change. Id. at 5–6. We agree with Flamm that Lam’s analysis improperly breaks the elements of independent claim 13 into small phrases, and then attempts to match disclosures from the prior art to those phrases taken out of context. In particular, we note that independent claim 13 recites that “the thermal mass of the substrate holder is selected for a predetermined temperature change within a specific interval of time during processing.” Ex. 1001, 21:1–3 (emphasis added). This claim language requires that these phrases are interdependent, and cannot be parsed into separate elements met individually. In other words, the thermal mass must be selected in order to undergo a predetermined temperature change within a specific interval of time, e.g., a change of 10°C per minute. Lam’s analysis is deficient, to the extent it separates selecting the thermal mass of the substrate holder from a predetermined temperature change within a specific interval of time and analyzes each separately.” slip op. at 16

      “We also do not find Dr. Cecchi’s supporting testimony on this particular issue to be persuasive. Ex. 1008 ¶¶ 73, 74. Dr. Cecchi’s analysis essentially repeats the arguments advanced in the Petition, and also breaks up the elements of the independent claim 13 into separate phrases that are then analyzed out of context. For these reasons, we do not credit his testimony that the combined teachings of Kadomura (embodiment 1) and Moslehi account for “the thermal mass of the substrate holder is selected for a predetermined temperature change within a specific interval of time during processing,” as recited in independent claim 13.” slip op. at 18

      “claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007).

Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). We analyze this asserted ground based on obviousness with the principles identified above in mind. 2. Kadomura Overview Kadomura generally relates to a dry etching method used primarily for the production of semiconductor devices and, in particular, to a dry etching method and apparatus that provides compatibility for anisotropic fabrication and high selectivity. Ex. 1002, 1:6–10. According to Kadomura, one objective of the disclosed dry etching method is to apply an etching treatment that includes a plurality of steps to a specimen within the same 3 Relying upon the testimony of Dr. Cecchi, Lam offers an assessment as to the level of skill in the art.
