“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.”). 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.

“We disagree with Patent Owner on this record. The language of claim 1 recites “location access rights of said device from said first wireless device.” The claim language does not limit the location access rights to be of only the one other device, at the exclusion of other devices. The ordinary and customary meaning of “location access rights of said device from said first wireless device” encompasses rights that allow other devices, in addition to the recited device, to access location information. The disclosure in the written description is consistent with the ordinary and customary meaning. Although the written description states that an object of the invention is to provide a security feature which allows a user to limit or deny access to a particular user, the written description discusses other purposes served by the assignment of access rights. For example, the written description discloses that “[u]sers may be added, individually or in groups, to a list of users with location access rights to a specific user by that specific user. A specific user may, at any time, modify, delete, or add users allowed to access his or her location.” Ex. 1001, 3:22- 26. The written description further discloses that “a user may organize his/her user list into groups and assign access rights to that group (e.g., family member user group, close friend user group).” Id. at 13:9–12. The fact that the written description of the ’039 patent sets forth multiple objectives to be served by the access rights confirms that these terms should not be construed as limited to a single device. Phillips, 415 F.3d at 1327. Further, because the written description here includes an embodiment where a user assigns access rights to a group, we are persuaded that the scope of the disputed claim terms encompasses a group permission. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed.

“Petitioner argues that a person of ordinary skill in the art would have made Petitioner’s proposed combination of “Degnbol’s disclosure of both selection of location-based events and manual entry using the handset of the phone with Sheha, to improve user ease, given that such techniques were well-known and conventional to POSAs at the time of alleged invention.” Pet. 18 (citing Ex. 1003 ¶ 132). Degnbol describes that “[i]t is an advantage of the present invention that user ‘A’ can be alerted when user ‘B’ arrives or leaves the defined location(s) or area(s)” so as “to enable user ‘A’ to know in advance the proximity or approximate whereabouts of user ‘B’ before possibly acting upon this information by contacting user ‘B’ — or allowing ‘B’ to contact ‘A.’” Ex. 1035, 3:23–27. At this preliminary stage, we find that Petitioner provides sufficient rationale to combine the teachings of Sheha, Degnbol, and McNulty for purposes of institution. Based on the evidence and arguments currently of record, we find that Petitioner demonstrates sufficiently for purposes of institution that the Sheha, Degnbol, and McNulty combination teaches the features recited in claim elements [1D] through [1F] and Petitioner provides sufficient rationale to make its proposed combination. We find that Patent Owner’s arguments do not undermine Petitioner’s showing. c) Conclusion—Claim 1 After consideration of the arguments and the evidence of record at this early stage, we determine that Petitioner has shown sufficiently, for purposes of institution, that the combination of Sheha, Degnbol, and McNulty teaches or suggests all recitations in claim 1. Also, we find that Petitioner provides sufficient rationale to combine the teachings of Sheha, Degnbol, and McNulty for purposes of institution.

“On this record, in considering the background knowledge as well as the inferences that an ordinarily skilled artisan would draw from Sheha’s disclosure, we are sufficiently persuaded that a person of ordinary skill in the art would have caused the mobile telephone to display the map of Figure 5.

The references cited by Mr. Williams explicitly show what is already implicitly taught by Sheha, namely, that displaying the map of Figure 5 on a mobile telephone was within the background knowledge of a person of ordinary skill.

Patent Owner also states that a “second IPR was filed against the same patent in proceeding IPR2024-01490.” Paper 4, 1. Patent Owner does not argue that we should exercise discretion under 35 U.S.C. § 314(a) because Petitioner uses more than one petition to challenge the ’731 patent. challenges the alleged priority date of the ’731 patent (IPR2024-01489) (‘First Petition’) and the second petition assumes that the Patent Owner’s claimed priority date is valid, and addresses prior art references predating that priority date (IPR2024-01490) (‘Second Petition’).” Ex. 1019, 1. In accordance with the Consolidated Trial Practice Guide1 (“CTPG”), issued in November 2019, “there may be circumstances in which more than one petition may be necessary” including “when there is a dispute about priority date requiring arguments under multiple prior art references.” CTPG 59. Such is the case here. Patent Owner does not file any Preliminary Response or other paper disputing Petitioner’s use of two petitions to challenge the claims of the ’731 patent. Based on the record before us, we consider the merits of both petitions because Petitioner’s stated reasons for filing two petitions are consistent with the CTPG. See generally Ex. 1019 (citing CTPG, 59 (“the Board recognizes that there may be circumstances in which more than one petition may be necessary, including, for example, . . . when there is a dispute about priority date requiring arguments under multiple prior art references)).

“information presented in the petition . . . and any response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314; see 37 C.F.R. § 42.4. Upon consideration of the Petition, the Preliminary Response, and the evidence of record, we determine that Petitioner has established a reasonable likelihood of prevailing with respect to the unpatentability of claims 1–39 of the ’633 patent.

- Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner
“May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

“Petitioner shows that (a) Mañosa (i.e., inorganic compounds such as Ni-Mn-In, Gd5Si2Ge2, and La-Fe-Co-Si) and (b) Patel (i.e., PVDF-TrFE- CTFE) teach materials exhibiting inverse BCEs. Pet. 59 (citing, inter alia, Ex. 1007, pages 4–8; Ex. 1009, 1, 4–5; Ex. 1004 ¶ 108). In our view, at this stage, Petitioner sufficiently shows (via the five reasons listed supra) why it would have been obvious to one of ordinary skill in the art to substitute the barocaloric cooling or heating agent of Patel for that taught in Mañosa, thereby reaching the claimed method with a reasonable expectation of success.

Teleflex Inc., 550 U.S. 398, 416 (U.S., 2007) (“The Court recognized that when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.”)” slip op. at 32
