“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

“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.

“Patent Owner contends that claim construction is necessary for the “seed-applied substance” term because Petitioner allegedly ignores the teaching of the specification in evaluating the term. Prelim. Resp. 12. Patent Owner points to the specification, which defines a “seed-applied substance” as “includ[ing] any composition applied to seeds prior to the seeds being planted (e.g., when the seed comes in contact with the soil in a field).” Id. at 13 (quoting Ex. 1001, 7:45-48). Patent Owner contends that the term means “a substance that is applied directly to the seed before the seed comes into contact with the soil in a field.” Id. (citing Ex. 2001, ¶ 55). According to Patent Owner, Petitioner erroneously uses a definition that “allows the ‘seedapplied substance’ to be applied to the seed (and soil) as the seed lay planted in the soil.’” Id.

“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.

“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.

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.

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

Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway.

Accordingly, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by 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.

“The parties do not identify any issue relating to the preamble that would impact our analysis. We recognize that Patent Owner is suggesting that Petitioner’s expert, at least, is reading the word “clinical” into the treatment language of claim 1. However, the plain language of the claim 1 preamble states “treating lymphoma or leukemia in a human patient” and is supported by a straightforward definition in the Specification of the ’087 patent, expressly limiting the invention to treatment of human patients. See Ex. 1001, 16:25–38. We therefore find that the preamble terms do not need claim construction because there is no actual dispute suggesting that, for example, claim 1 implicitly recites the term “clinical.” See, e.g., Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

“d. Analysis Considering the Wands factors as a whole, we find that the limited breadth of the claims, presence of several working examples, significant amount of direction and guidance provided by the ’087 patent, predictability in treating blood cancers with Bcl-2 inhibitors like GDC-0199, and high level of skill in the art are balanced against a large quantity of experimentation. Based on our consideration of the entirety of the evidence, we find that a preponderance of the evidence supports the conclusion that undue experimentation would not have been required to make and use the invention commensurate in scope with the claims of the ’087 patent. One underlying theme of Petitioner’s contentions and Petitioner’s expert testimony is the repeated contention that clinical trials were not completed by Patent Owner. See, e.g., Pet. 48 (“venetoclax (GDC-0199) was not FDA-approved”); Ex. 1020 ¶ 193. We find these arguments unpersuasive as we agree with Patent Owner that “[i]t is well established that a patent may be secured, and typically is secured, before the conclusion of clinical trials.” In re Montgomery, 67 F.3d 1375, 1382 (Fed. Cir. 2012). Particularly as to the dependent claims, a preponderance of the evidence of record does not support a finding that undue experimentation would have been required to administer three different doses of GDC-0199 starting with 100 mg, to use multiple daily dosing cycles of one day, to continue until disease progression occurs, or to combine with other treatment compounds. We find that a preponderance of the evidence does not support Petitioner’s position that any of the dependent claims fail to comply with the enablement requirement.” slip op. at 23

“Applying Rai and Wertheim to the instant facts, we agree with Patent Owner that, factually and legally, in the ’087 patent “the claimed dosages of 100 mg, 200 mg, and/or 400 mg of GDC-0199 are adequately supported.” PO Second Suppl. Brief 2 (citing PO Resp. 11, 27–29; PO Sur-reply 19, 21– 22; Ex. 1001, 24:20–29.) In particular, the ’087 patent describes all three specific dosage values 100 mg, 200 mg, and 400 mg in the context of an escalating drug dosage series and Petitioner points to no persuasive statements in the specification that dispute either the effectiveness or the operability of GDC-0199 at any of these dosages.” slip op. at 32
