“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.

“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.

In addition, Petitioner explains that adding per-application data usage monitoring to Bennett’s device “would have enabled device manufacturers and service providers to incorporate additional applications and functionality into wireless devices while allowing users to retain control of aggregate device data usage.” Id. at 17 (citing Exs. 1003, 1042).

“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. Cf. KSR Int’l Co. v. 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

“Considering these disclosures together with the cited paragraphs of Petitioner’s declaration, Petitioner sufficiently shows on the present record that one of ordinary skill in the art would have understood that, in Shell, when a user attempts a voice call, the user can cause a current data connection to disconnect, because (1) a voice-related connection request will be made, (2) the request for voice connection will be prioritized over data requests, and (3) the request will also be prioritized if it is coming from an active application rather than an application running in the background. Pet. 47; Ex. 1003 ¶ 140; Ex. 1005 ¶¶ 8, 13, 14, 57. On the preliminary record, the relied-upon portions of Shell adequately show a determination of whether an application is an active application for prioritization purposes and disconnecting a current data connection due to a user attempting to make a voice call. Ex. 1005 ¶¶ 8, 13, 14, 57. The attempt to make a voice call would be a user interaction resulting in a request for a voice connection that would be prioritized over the data request of another application using the current data connection. See Ex. 1005 ¶¶ 8, 13, 14, 57. The attempt to make a voice call also involves a user interacting with an application to make it an active background. See Ex. 1003 ¶ 140. Petitioner, thus, sufficiently shows for institution that Shell’s processor is “configured to determine that the different application is an active application based on a user interaction with the different application,” as required by claim 26.

“One of ordinary skill in the art, Petitioner argues, would have, thus, been motivated to look to references, such as Cole, that provided mobile devices with network access while addressing cost, power, and network selection. Pet. 13–14 (citing Ex. 1003 ¶ 68; Ex. 1006, code (57), ¶¶ 14–15, 78, 83, 88, 98). Petitioner also argues that Cole describes Internet access control techniques based on conditions, such as power state change and load on current communication links, and that applying Cole to Shell would have “promoted more efficient communications and network access connectivity.” Id. at 14 (citing Ex. 1003 ¶ 68; Ex. 1006 ¶¶ 83, 98). Using Cole’s techniques, the proposed combination, Petitioner explains, would have evaluated network and power conditions, determined whether to apply an Internet access control, evaluated further conditions, such as whether the application is running in the foreground or background, and then determined the priority of packets traveling over the selected network. Pet. 14 (citing Ex. 1003 ¶ 68; Ex. 1005 ¶ 92; Ex. 1006 ¶¶ 11, 78, 83, 88, 98).

Petitioner further argues that the proposed combination would have included the processors, non-transitory memory, and display, as taught by both references, to perform the recited operations.

Petitioner additionally argues that one of ordinary skill in the art would have had a reasonable expectation of success in making the proposed combination because it “would have required only routine programming knowledge well within [ordinary] skill,” “would have amounted to nothing more than the use of a known technique to improve similar devices . . . in a similar way,” and would have been “combining prior art elements according to known methods to yield predictable results.” Pet. 15–16 (citing Ex. 1003 ¶¶ 73, 74; Ex. 1005 ¶¶ 36, 40; Ex. 1006 ¶¶ 34, 35, Fig. 2).” slip op. at 21
