“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

“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.”).

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.

“Patent Owner attempts to distinguish the scope of the claims between the related ’334 patent and ’391 patent, where the claims of the ’334 patent recite a “an endoxifen composition encapsulated in an enteric capsule.” Prelim.

Patent Owner contrasts this with the scope of the claims of the ’391 patent and contends that the challenged claims are directed to “the underlying composition itself, where the enteric material is an ingredient of the composition combined with the endoxifen.” Id. To support its contentions, Patent Owner attempts to apply the doctrine of claim differentiation across patents, noting that [t]he related ’334 describes a composition where the enteric requirement is not part of the composition, reciting “[a]n oral formulation comprising an endoxifen composition encapsulated in an enteric capsule.” EX2014, cl.1.

“distinguish the preamble language reciting “[a] composition comprising an endoxifen and an enteric material” from Ahmad. Prelim. Resp. 13–16. Specifically, Patent Owner contends that Petitioner’s arguments rely on Ahmad’s alleged disclosure of endoxifen encapsulated in enteric-coated capsules. Id. at 14. For example, Patent Owner contends that “every portion of Ahmad relied upon by Petitioner describes a ‘composition containing endoxifen’ that can then be coated with a separate external ‘enteric coating.’” Id. at 15. Patent Owner further contends that these disclosures fail to disclose an enteric material that is a component (with endoxifen) of the composition itself. At most, these disclosures purport to describe (1) a pharmaceutical composition of endoxifen (2) encapsulating the finished composition in a separate external enteric coating. See EX1003, 18:27-29 (“Enteric coating of capsules filled with composition art.”). Prelim. Resp. 15. Patent Owner therefore concludes that “Petitioner identifies no teaching in Ahmad that the enteric material is a component of the endoxifen composition, as claimed.” Id. at 16. Based on our preliminary construction of the term, “[a] composition comprising an endoxifen and an enteric material” discussed above, and, having considered the arguments and evidence presented by the parties at this stage of the proceeding, summarized above, we find that Petitioner has shown it is more likely than not that Ahmad discloses each limitation of claims 1 and 32 for the reasons stated in the Petition, which we adopt for purposes of this Decision.

“At this stage, we find Petitioner’s description of the level of ordinary skill in the art to be sufficient. According to the ’360 patent, “[t]he field of the invention is related to sensor arrays for the detection and diagnosis of disease states.” Ex. 1001, 1:28–29. The Specification describes accomplishing such by analysis of protein coronas using techniques such as LC-MS/MS. See id. at 4:43–5:2 (describing Figure 1). The prior art cited by Petitioner also describes the analysis of protein coronas using similar analytical techniques. See, e.g., Ex. 1005, 584; Ex. 1007, 1870; Ex. 1008, 355–356. Accordingly, the present record supports that a POSA would have an understanding of both proteins and the analytical techniques, e.g., mass spectrometry, that can be used to characterize them. We understand Petitioner’s definition of a POSA to encompass these elements. It requires a formal degree in chemistry,5 which itself entails some knowledge of proteins and related analytical techniques, along with several years’ additional experience in proteomics, protein analysis, or mass spectrometry. Moreover, Petitioner’s definition is flexible in that it allows higher education or skill with, e.g., mass spectrometry, to make up for a lack of specific experience with proteomics assay and protein coronas. This explanation is reasonable and supported on the current record.” slip op. at 8

A person need not be a person of ordinary skill in the art to testify as an expert under Federal Rule of Evidence 702, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008). Here, there is no dispute that Dr. Vargas is qualified in the art of mass spectrometry and, on the current record, we discern no reason why she is not qualified to offer the testimony in her declaration. At most, Patent Owner’s argument that Dr. Vargas lacks experience “perform[ing] mass spectrometry techniques specifically for protein analysis,” goes to the weight we should afford her testimony at trial. See Prelim. Resp. 28–29. It is not a sufficient reason to deny institution, particularly given that Dr. Vargas’s testimony is only part of the showing offered in support of the Petition. 6 Patent Owner’s narrow characterization of Dr. Vargas’s experience (see Prelim.

“c) Analysis On the current record, we are persuaded that Petitioner has demonstrated a reasonable likelihood that the subject matter of claim 1 would have been obvious over the combined disclosures of Yang and Mullins. First, Patent Owner asserts that Yang does not disclose the limitation of “a controller . . . to control fluid flow in and out from the distal end.” Prelim. Resp. 21– 32. On the current record, we agree with Patent Owner that introducing a positive pressure pulse such as through the water hammer effect does not necessarily mean that there will be an overall distal end. See Ex. 2001 ¶¶ 53–54; Ex. 2005 ¶ 60; Ex. 2007, 51 n.12. This is especially true if an overall vacuum state is maintained in the catheter. See Ex. 2001 ¶ 56; Ex. 2007, 43; Ex. 2010, 125:11–18. Further, on the current record, we credit the testimony of Patent Owner’s declarant, Mr. Culbert, that to have flow out of the catheter’s distal end when it is in a patient, the pressure in the catheter needs to exceed mean arterial pressure. See Ex. 2001 ¶ 59; Ex. 2010, 126:15–21. Therefore, on the current record, we agree with Patent Owner that Yang may not explicitly disclose flow out from the distal end of the catheter. Whether Yang alone renders this limitation obvious may be explored further on a full trial record; however, because this limitation appears to be taught by Mullins and Petitioner has shown on this record that a POSA would have been motivated to combine the disclosures of Yang and Mullins, we are sufficiently persuaded that Petitioner has met its burden to show a reasonable likelihood that this limitation is rendered obvious by the combined disclosures of Yang and Mullins.” slip op. at 18

“As explained in the -459 IPR, we do not discern much of a substantive difference between the parties’ respective definitions in this proceeding beyond the number of years of experience after obtaining a doctoral degree. Compare Pet. 12, with Prelim. Resp. 21. For purposes of this Decision, we adopt Patent Owner’s definition as it appears to be reasonable and falls between Petitioner’s definitions asserted in the Petition and in its request for reexamination of the ’781 Patent. See Ex. 2001 ¶ 51. Moreover, Patent Owner’s definition appears consistent with the prior art’s demonstration of the level of ordinary skill in the art at the time of the invention. 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. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). To the extent the parties continue to disagree on the level of ordinary skill in the art, they should brief the issue further during trial.” slip op. at 8

“(citing Ex. 2004). Our rules explain: “The patent owner may file a statutory disclaimer,” and “[n]o inter partes review will be instituted based on disclaimed claims.” 37 C.F.R. § 42.107(e). Patent Owner filed a statutory disclaimer on October 24, 2024. Ex. 2004. A disclaimer under 35 U.S.C. § 253(a) is “considered as part of the original patent” as of the date on which it is “recorded” in the Office. 35 U.S.C. § 253(a). For a disclaimer to be “recorded” in the Office, the disclaimer must: (1) Be signed by the patentee, or an attorney or agent of record; (2) Identify the patent and complete claim or claims, or term being disclaimed. . . .; 3) State the present extent of patentee’s ownership interest in the patent; and (4) Be accompanied by the fee set forth in [37 C.F.R.] § 1.20(d). 37 C.F.R. § 1.321(a); see also Vectra Fitness, Inc. v.

Although we agree encompassing RFIDs attached or implanted “on or within” an animal, the plain language of the claim expressly recites “in,” which, on the present record, we determine corresponds to “within” as described by the ’515 patent Specification.
