“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.

“motivated and found it obvious to modify Ferro-Oyobe-Donnelly to include Letendre’s graphical slider on the charge level bar graph of the GUI as a third portion, where the operator moves the slider to specify a desired charge.” Pet. 60 (citing Ex. 1003 ¶ 235). Petitioner contends that Ferro- Donnelly already reflects a system with a GUI on a touchscreen for depicting state of charge and modifying that GUI to add a slider for specifying the state of charge is expressly motivated by Letendre’s indication that “it is essential that the driver be able to limit any draw down so travel is not affected.” Id. (citing Ex. 1007, 19). Letendre also describes its GUI with the slider as “a control that the driver sets according to driving needs.” Id. at 59 (citing Ex. 1007, 19). Ferro’s express description of an input/output device for managing charging preferences and Letendre’s express description of a GUI for setting charging parameters suggest using Letendre’s GUI with Ferro’s system. Id. at 60–61 (citing Ex. 1003 ¶ 236). Petitioner also argues that its proposed combination constitutes “applying a known technique ([Letendre’s] slider . . .) to a known device ([Donnelly’s] vehicle GUI showing a charge bar graphic) ready for improvement to yield predictable results of easily allowing a user to choose a desired level of charge.” Id. at 61 (citing Ex. 1003 ¶ 237). Petitioner also contends that “[s]liders on GUIs were known to make inputting information easier, and thus [an ordinarily skilled artisan] would have been motivated to include a slider on the bar graph.” Id. (citing Ex. 1003 ¶ 237). An ordinarily skilled artisan would have reasonably expected to successfully combine Letendre’s slider in the GUI suggested by Ferro-Donnelly because that GUI already enabled setting charging preferences including “amount of charge” (i.e., minimum and maximum).

“We disagree with Patent Owner. It is true that Oyobe focuses on alerting a vehicle user to a low state of charge by raising a physical indicator on the exterior of the vehicle (i.e., the “informing apparatus 102) when the battery is low. Ex. 1005 ¶ 40. Oyobe explains: even in such a case where the vehicle user exit from the vehicle without checking the SOC of main battery B on the console panel, informing apparatus 102 disposed at a location where it can easily be seen outside the vehicle by the vehicle user allows the vehicle user to easily recognize the necessity of charging main battery B. Id. However, Oyobe’s focus on raising a physical indicator on the vehicle as a reminder does not detract from Oyobe’s unambiguous disclosure that its vehicle also includes position detecting apparatus 108 that uses wireless communication to “sense that the vehicle is parked at the location where charging equipment is installed.” Id. ¶ 142. Oyobe’s ability to sense whether a vehicle is parked next to a charger allows Oyobe’s system to remind the user to charge the battery by raising low battery indicator 102 while the vehicle is located next to a charger but not “where charging cannot be performed.” Id. ¶¶ 143–145. Accordingly, regardless of the reason that Oyobe provides for including its vehicle position detecting apparatus, Oyobe undeniably describes a vehicle sensor that can provide “information indicative of a presence of an electric vehicle in a parking space” near a charging station. And, we find that Petitioner has sufficiently explained why an ordinarily skilled artisan would have been motivated to use Oyobe’s sensor in Ferro’s electric vehicle to “advantageously allows a user to instruct charging without exiting the vehicle and physically interacting with a charging station.” Pet. 11–12 (citing Ex. 1003 ¶¶ 150–152).” slip op. at 20

Not only do we find Petitioner’s reliance on Mr. Andrews’s testimony to be persuasive, but we also find that Mr. Andrews’s citations to Exhibits 1018, 1053, 1057, and 1059 provide strong support for his testimony that an ordinarily skilled artisan would understand that Oyobe teaches that its vehicle is in a parking space when Oyobe’s apparatus 108 detects that “the vehicle is parked” near charging equipment.

“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

“The primary basis for Patent Owner’s argument is the fact that the ’111 patent has been subject to previous inter partes reviews filed by other parties.2 Id. at 14–19. A related fact—not fully addressed by Patent Owner—is that Patent Owner has staggered-in-time its suits alleging infringement of the ’111 patent against different parties. Patent Owner sued Cisco Systems in July 2022, but waited a year to separately file suit against Juniper Networks and Petitioner. IPR2023-00554, Ex. 1010; IPR2024- 00037, Paper 2. Patent Owner was not obligated to sue Petitioner at the same time that it sued Cisco Systems. Similarly, Petitioner was under no obligation to request to join Cisco System’s earlier filed inter partes review. See Prelim. Resp. 16. Rather, as acknowledged by Patent Owner, Petitioner waited to file the present inter partes review until the last day allowed under statute. Id. at 15, 17. Based on the circumstances before us, we do not agree with Patent Owner that it would be appropriate to enforce a deadline on Petitioner that is earlier than the deadline outlined by statute. See id. at 16.” slip op. at 3

“Petitioner also provides an extensive discussion of the reasons to combine Chua with the system of Lefebvre, such as due “to Chua’s more detailed teachings regarding actions an SDN controller takes in response to information from security-related services like DPI.” Id. at 25 (citing Ex. 1002 ¶ 102); see also, e.g., id. at 24–26 (discussing reasons to combine). Petitioner also provides a detailed discussion of how the combined teachings of Lefebvre and Chua teach the method steps of claim 1. Id. at 32–39; see also Ex. 1002 ¶¶ 115–136.

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Neither Petitioner nor Patent Owner proposes constructions for any claim terms. See Pet. 12; Prelim. Resp. 2. Based on the current record, we need not construe explicitly any claim terms because doing so would not change the outcome of the analysis below. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“On the current record, Petitioner adequately explains the reasons to combine Butler with Jianan to arrive at the first two alternative devices. The discussion on the reasons to combine Butler and Jianan spans over nine pages of the Petition, with approximately twenty paragraphs of the Giachetti Declaration supporting that discussion. See Pet. 13–22; Giachetti Decl. ¶¶ 78–98. Patent Owner selects one statement from Petitioner’s discussion and asserts that that single statement is inadequate. Moreover, Patent Owner relies on mere conclusory attorney argument as to the alleged technical issues that would have been identified by one of ordinary skill in the art. See Elbit Sys., 881 F.3d at 1359. On the current record, we determine that Petitioner has made a sufficient showing that a person of ordinary skill in the art would have had reason to modify Butler and Jianan as proposed and that the articulated reasoning is supported by rational underpinning, at least as to the first two alternative devices (as discussed above).” slip op. at 25

“At this stage of the proceeding, Petitioner adequately explains the reasons to combine Dimbylow and Howes. The discussion on these issues spans eight pages of the Petition, with approximately nine paragraphs of the Giachetti Declaration supporting that discussion. In contrast, Patent Owner relies on mere conclusory attorney argument as to the Petition’s alleged failings. See Elbit Sys., 881 F.3d at 1359. Moreover, the relied-upon prior art need not expressly teach or suggest the proposed combination and also need not identify modified components as a “problem.” See KSR Int’l, 550 U.S. at 418 (discussing how the obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ”). Second, Patent Owner argues that because Dimbylow discloses a hand vacuum and Howes discloses an upright vacuum with no attachable cleaning tool, “there is no evidence a [person of ordinary skill in the art] would have looked to Howes to fill in alleged gaps in Dimbylow.” Prelim. Resp. 14–15. On the current record, this argument does not identify a deficiency in Petitioner’s position. As an initial matter, Patent Owner has not adequately explained why the overall form factor of the devices in the relied-upon prior art—i.e., a hand vacuum versus upright vacuum—would impact the motivation to combine when the aspects relied on from Howes relate more narrowly to structures allowing opening of dust collection units (a problem common to both hand vacuums and uprights). See, e.g., Pet. 18 (discussing why one of ordinary skill in the art “would have been particularly motivated to look at similar references (including cyclonic vacuum-cleaner references having the same assignee, Dyson) that teach mechanisms to release a similar component (door catch) on a similar device (dirt collection chamber) to accomplish a similar goal (hygienic and convenient bin emptying)” (citing Giachetti Decl. ¶ 84)); see also In re Paulsen, 30 F.3d 1475, 1481–82 (Fed. Cir. 1994) (affirming rejection of a laptop computer hinge as obvious over hinged cabinets, piano lids, etc., because the “problem is not unique to portable computers”). Patent Owner’s conclusory statement that “no evidence” has been presented does not address Petitioner’s positions.” slip op. at 24
