PO Resp. 7–10. Patent Owner also points to dependent claims 6–9 as relying on the preamble reciting “a deodorant stick” as antecedent basis for claim elements. Id. at 9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 19 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick). We determine that no express construction of any claim term is necessary to determine whether to institute inter partes review. Nidec Motor Corp. v.

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.

      “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 concedes that the Specification does not describe a representative number of members of the genus, stating “this is a common structural features case.” Tr. 65:25–66:3.

      “For a functionally-defined genus, “the written description requirement [can be met] when the art has established a correlation between structure and function.” Ariad, 598 F.3d at 1350. Here, the challenge claims recite two types of functional limitations. First, independent claim 10 requires the coformer to have a second chemical functionality, which is defined as being complementary to the first chemical functionality via non-covalent hydrogen bonding. That is, the co-former’s second chemical functionality must be complementary to either a carboxamide, carbonyl, or amine functionality of an API via non-covalent hydrogen bonding. Second, the non-covalent hydrogen bonding between the first chemical functionality of the API and the second chemical functionality of the co-former must result in the formation of supramolecular synthons.” slip op. at 21

In this way, the ’284 patent specification discloses generating “an index of treatment efficacy” where “the index [is] based in part on data of severity of sleep disorder symptoms of the subject and data of usage of the PAP device by the subject,” because the system uses data collected from the sensors to evaluate the severity of the subject’s sleeping disorder and efficacy of the current treatment, and can adjust the treatment without human intervention as needed.

We find that Petitioner has failed to demonstrate, more likely than not, that any experimentation would have been undue in view of the Wands factors. Prelim. Resp. 25 (citing Wands, 858 F.2d at 737). On this record, Petitioner has not demonstrated that the claimed subject matter is unpredictable or would require undue experimentation. Petitioner argues that “the challenged claims are not enabled regarding the ‘index of treatment efficacy’ claim elements.” Pet. 24. But as Patent Owner establishes, Petitioner acknowledges that determining treatment efficacies was merely applying a known technique. See Prelim.

Petitioner, however, has not demonstrated, more likely than not, that it would take undue experimentation to carry out such display or transmission. The Petition merely suggests that the specification lacks enablement of these claim limitations, but fails to provide any analysis of pertinent factors, such as the state of the prior art, the level of ordinary skill, or the level of predictability in the art with regard to displaying and transmitting data on a cell phone at the time of the invention.

      “In this post-grant review, we construe the claims of the ’284 patent “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. § 282(b).” 37 C.F.R. § 42.200(b) (2019).

What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). 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. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it.
