“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.

“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. Osseo Imaging, LLC v.

“C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

[A] POSITA implementing Bharadwaj’s preamble designs would have been motivated to look to another reference, like Sun, for an understanding of the format of the user field that would support non-MU-MIMO allocations and the single-user transmission scenario. A POSITA would have combined the teachings of Bharadwaj with Sun to realize implementation details for the HE-SIG-A and HE-SIG-B fields of the HE MU PPDU to better support both MU-MIMO and non-MU-MIMO allocations. SAMSUNG-1003, ¶¶153-158. . . . . A POSITA would have found it obvious to look to Sun for modifying Bharadwaj to include the user field format for SU (non-MU-MIMO) allocation to complement Bharadwaj’s disclosure of the MU-MIMO user field format and to provide a more complete system that would allow HE MU PPDUs to support both MU-MIMO allocations for multiple users and non-MU-MIMO allocations for a single user. SAMSUNG- 1003, ¶¶153-158. The combination also would have been obvious and predictable for at least the following reasons: 1) both Bharadwaj and Sun describe designs for a PHY data unit (or PPDU) to support communications between an AP and a station within a high-efficiency Wi-Fi network, consistent with 802.11ax; 2) both Bharadwaj and Sun describe the PPDU design for supporting MU-MIMO downlink transmission as including HE- SIG-A and HE-SIG-B fields; and 3) Bharadwaj already describes the format for the user field for the MU-MIMO allocation, while also recognizing the single-user scenario, and the combination merely involves the addition to Bharadwaj of the user field format for the single-user allocation, as taught by Sun. SAMSUNG-1003, ¶¶153- 158. The combination is obvious also because elements of the combined system would each perform similar functions they had been known to perform in similar contexts outside the combination.

“The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious.

“claims a method of treating a human patient with colorectal cancer having certain characteristics using pembrolizumab and the main prior art reference cited by Petitioner discloses testing pembrolizumab to treat human patients. (See Ex. 1001, 25:40–50, Ex. 1005; see Decision 8–9.) Accordingly, the relevant field of Patent Owner’s claims is treating human patients, as well as testing existing compounds. Neither party directs us to evidence of the level of skill in the art beyond what we considered for institution of trial. In the Decision to institute trial, we determined that the level of skill in the art relevant to the claims of the ’393 patent is not limited to knowledge of and experience with conducting research relating to oncology or developing and conducting clinical trials. (See Dec. 8–9.) We determined that the level of skill also includes knowledge of and experience with treating colorectal cancer patients with immunotherapy compounds, identifying the conditions these patients may have, and understanding the literature regarding clinical trials for such colorectal cancers and the associated conditions and immunotherapy. (See id.) Because the parties do not present additional evidence or argument, we maintain that determination.” slip op. at 9

“1 requires a causal relationship wherein the patient must be tested for MSI-H and, if he or she is determined to be MSI-H or dMMR, then the patient is treated with 10 mg/kg of pembrolizumab every 14 days. We further agree that this relationship is different than the use of the term “after” in claims 7, 20, and 27, wherein patients must be treated with a different cancer therapy, and wherein the cancer must have later progressed for the treatment to be within the scope of these claims. (Ex. 1001, 25:66–7, 26:44–46, 26:63–64.) In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab. For this reason, if the prior art teaches the limitations of 1) testing a biological sample obtained from a patient having colorectal cancer to determine that the patient’s colorectal cancer is microsatellite instability high or mismatch repair deficient, and 2) treating the patient with a therapeutically effective amount of pembrolizumab if the patient’s colorectal cancer is determined to be microsatellite instability high or DNA mismatch repair deficient, the art anticipates claim 1. We are not persuaded that claim 1 requires or excludes anything else because nothing else is recited in the claim.” slip op. at 12

“Petitioner proposes the following claim constructions: “an allocated block of serial numbers” as “a pre-authorized range of binary serial numbers” and “uniquely corresponding” as the “term’s plain and ordinary meaning, consistent with the articulation of the plain and ordinary meaning” in the Avery Dennison litigation. Pet. 8–12. As to the remaining claim terms, Petitioner applies the district court’s constructions in the Avery Dennison litigation. Id. at 12 (citing Ex. 1028). Patent Owner applies the following constructions that were entered during in the Avery Dennison litigation: “object class information space” as “data field within the memory of the RFID integrated circuit chip for information identifying the class of an object, such as a company prefix, item reference code, partition value, and/or filter value,” “unique serial number space” as “data field within the memory of the RFID integrated circuit for information identifying a unique serial number,” “being assigned a limited number of most significant bits” as “includes a limited, predefined sequence at the leading end,” “remaining bits of lesser significance” as “the remaining lower order bits at the trailing end,” “is encoded with one serial number instance” as “has stored within it one serial number instance,” “an allocated block of serial numbers” as “a pre-authorized range of serial numbers,” and “uniquely corresponding” as its plain and ordinary meaning.

“However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15

“Owner is telling. Petitioner does not refute Patent Owner’s evidence of objective indicia. On the current record, the objective indicia evidence is compelling. As to long felt need, Patent Owner cited evidence on record before the Examiner that showed a persistent need recognized by ordinarily skilled artisans. In re Gershon, 372 F.2d 535, 538 (CCPA 1967). For example, Dr. Huang states “This research is the breakthrough we have been waiting for since nearly a century . . . This is crucial for the potato breeding worldwide.” Ex. 2009, 687.

“Petitioner contends that one motivation for combining would have been that Marcus ’904 includes additional disclosure of targeting media programming to specific users, which would lead to better customization of media programming by Cristofalo. Pet. 38 (citing Ex. 1002 ¶ 122). This assertion is vague and unexplained. Petitioner also asserts that Marcus ’904 provides “additional implementation details” on how final media programming is generated and formatted for display. Id. at 38–39 (citing Ex. 1002 ¶ 123). We fail to see, at this stage, how merely disclosing additional details would motivate a skilled artisan to combine references. If we were to agree with a proposed combination merely because one reference includes details another does not, this could “swallow all of patent law.” Cf. Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 217 (2014) (addressing patent eligibility). Finally, Petitioner contends that combining Marcus ’904’s advertising sources would unlock new revenue sources for Cristofalo. Pet. 39 (citing Ex. 1002 ¶ 124). Patent Owner argues that this rationale appears to be superfluous, since Cristofalo already discloses targeting advertising to users. Prelim. Resp. 26 (“Cristofalo’s receiving system ‘already’ assembles the programming with advertisements.”); see Pet. 38 (referring to Cristofalo’s “targeted advertising”). We tend to agree at this stage. Thus, we question Petitioner’s rationale to combine Cristofalo with Marcus ’904.” slip op. at 16
