      “an inter partes review, “the Director may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.” The Board uses a two-part framework when determining whether to exercise its discretion under 35 U.S.C. § 325(d), specifically: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if so, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims.

      “each of its elements was, independently, known in the prior art.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). An obviousness determination based on a combination of references requires finding “both ‘that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.’” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367–68 (Fed. Cir. 2016) (citation omitted); see KSR, 550 U.S. at 418. Further, an assertion of obviousness “cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418; In re NuVasive, Inc., 842 F.3d 1376, 1383 (Fed. Cir. 2016) (a finding of a motivation to combine “must be supported by a ‘reasoned explanation.’” “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3)); see also Intelligent Bio-Sys., 821 F.3d at 1369. Therefore, to prevail in an inter partes review, Petitioner must explain how the proposed combination of prior art would have rendered the challenged claims unpatentable. At this preliminary stage, we determine whether the information presented in the Petition shows there is a reasonable likelihood that Petitioner would prevail in establishing that at least one of the challenged claims would have been obvious over the proposed combination of prior art.

      “It is well established that collateral estoppel applies to IPR proceedings.” Google LLC v. Hammond Dev. Int’l, 54 F.4th 1377, 1381 (Fed. Cir. 2022). Collateral estoppel, i.e., issue preclusion, applies when “(1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party.” VirnetX Inc. v.

      “We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003) (“First, we look to the claim language to determine if, as a matter of logic or grammar, [the recited steps] must be performed in the order written.”).” slip op. at 8

Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). In response, Patent Owner argues that Petitioner’s obviousness analysis is flawed because “there is no articulated reasoning regarding what specific element of claim 45 Buibas . . . does not disclose.” Prelim. Resp. 19–20. In other words, according to Patent Owner, Petitioner “failed to perform a proper obviousness analysis because Petitioner has failed to identify anything in the claims that Buibas lacks disclosure of for Ground 1A.” Id. at 20. Based on the present record, we determine that Petitioner has set forth sufficient reasoning to support a motivation to combine Buibas and Sinyavskiy for purposes of institution, as well as sufficient reasoning to support the conclusion that one of ordinary skill would have had a reasonable expectation of success in making the combination. We do not agree with Patent Owner’s argument that Petitioner’s obviousness analysis is flawed because it fails to identify what is lacking in Buibas’s disclosure. To the contrary, Petitioner explains that Buibas “broadly suggests” that its spiking neural networks “can be partitioned into modules for different tasks or behaviors” but “discloses little detail about the partitioning,” and that Sinyavskiy’s more detailed disclosure of partitioning spiking neural networks would fill in these details. See Pet. 12–13, 14–15, 24. Petitioner also relies on Sinyavskiy’s more detailed disclosures concerning partitioning the network to satisfy limitations [45.1] and [45.6]. Id. at 23–27, 35.

      “On this record, Patent Owner’s argument is unavailing. First, the evidence of record indicates that Li and Wu are analogous art. Pet. 70; Ex. 1003, Bhattacharjee Decl. ¶ 201. For example, the ’845 patent, Li, and Wu are all directed to the same field of endeavor, namely, computer networking and routing data packets. Ex. 1001, 1:17–21, Ex. 1003 ¶ 201; Ex. 1037, 1; Ex. 1039, 9. Second, the evidence of record indicates that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the cited teachings of Li and Wu. Pet. 78–79 (citing Ex. 1003, Bhattacharjee Decl. ¶ 207). As discussed above, Petitioner relies on Wu’s teaching that an IPv6 destination address includes a destination port number. Pet. 79–80 (citing Ex. 1003, Bhattacharjee Decl. ¶ 211). Even if Patent Owner is correct that Li and Wu address the interoperability of IPv4 and IPv6 networks from different perspectives, a person of ordinary skill in the art would have reasonably expected that Wu’s destination port number could be incorporated into the unused padding in Li’s IPv6 destination address. Pet. 76–80; Ex. 1003 ¶¶ 199–212. On this record, Petitioner shows sufficiently that an ordinarily skilled artisan would have had reason to combine the cited teachings of Li and Wu.” slip op. at 51

      “An inter partes review may not be instituted unless “the 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(a). Further, when instituting an inter partes review, we “will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). Here, Petitioner demonstrates a reasonable likelihood of prevailing in showing that at least one of the challenged claims is unpatentable.

      “the same standard used in a civil action under 35 U.S.C. § 282(b), including construing the claim in accordance with the ordinary and customary meaning of the claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner notes that several claim terms previously were construed by a district court in another case. Pet. 10–14 (citing Ex. 1036). Patent Owner proposes construing the term “domain” to mean “a network or subnetwork and its address space that are under common control.” Prelim. Resp. 19–21. Petitioner disagrees with Patent Owner’s proposed construction of the term “domain.” Pet. 31. We determine that no claim terms require express construction for purposes of this Decision. As discussed below, even if we assume that the term “domain” means “a network or subnetwork and its address space that are under common control,” Petitioner shows sufficiently that at least one of the challenged claims is unpatentable. See Section II.E.1. As a result, we need not resolve the parties’ dispute about the meaning of the term “domain” for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “As discussed above, Petitioner presents evidence that although Li-2 “never became an official Internet-Draft published in the IETF directory,” Li-2 remained in the IETF’s staging folder. Pet. 20–22; Ex. 1009 ¶¶ 10–11. But the evidence of record indicates that the IETF’s staging folder may contain thousands of documents. Prelim. Resp. 35; Ex. 1008 ¶ 4; Ex. 1044. This raises the issue of whether a person of ordinary skill in the art exercising reasonable diligence could have located Li-2 simply by browsing the filenames of the numerous documents in the IETF’s staging folder. Patent Owner may address this issue again and present any other arguments regarding this asserted ground in its Patent Owner Response. Petitioner also presents evidence that the IETF’s Datatracker included Li-2 for “a given period” after the authors canceled Li-2. Pet 22; Ex. 1008 ¶ 11. But Petitioner does not indicate how long the IETF’s Datatracker would have included Li-2 (e.g., hours, days, weeks, years). See Pet. 22; Prelim. Resp. 36; Ex. 1008 ¶ 11. This raises the issue of whether Li-2 was present in the IETF’s Datatracker such that a person of ordinary skill in the art exercising reasonable diligence could have located Li-2.

      “virtual machines” is not a definition of the term, but rather describes how a virtual machine is created. The sentence following the reference to creating virtual resources as “software constructs,” on which Patent Owner relies, states, “[t]he virtual resources are then assigned to virtual machines used for respective servers.” Ex. 1001, 13:46–48 (emphasis added). Thus “virtualization” refers to creating virtual machines by assigning virtual resources as software constructs, but the nature and scope of what constitutes a “virtual machine” is unresolved by Patent Owner’s proposed construction. See Reply 5. In any event, like Petitioner, Patent Owner ultimately argues that it is unnecessary to pin down the outer bounds of the construction of “virtual machine,” because, according to Patent Owner, McCarthy discloses virtual machines under any of the constructions that have been considered here. Sur-Reply 17–20.” slip op. at 15

    • Expert testimonyPetitioner expert creditedDecided for petitioner

      “We credit the testimony of Petitioner’s expert Dr. Madisetti, which provides adequate support for Petitioner’s asserted combination. Moreover, Petitioner’s obviousness analysis is supported by the undisputed fact that virtual machines and their advantages were well known at the time of the McCarthy application, and by the prosecution history of the ’005 patent, during which, as discussed above in Section III.D.2.a), the Examiner cited references disclosing virtual machines in finding the then-pending claims obvious. Ex. 1002, 47–59. Applicants overcame that rejection by amending the claims to add the requirement that the second manager process maintain a list of priority levels and quantity of needed resources (a requirement now satisfied by McCarthy). Id. at 113–115, 181–192. But the basic finding of the Examiner that virtual machines were a well-known and obvious technique at the time of the ’005 invention supports Petitioner’s challenge. Accordingly, we determine that Petitioner has provided sufficiently articulated reasoning with rational underpinnings for the proffered combination of McCarthy and Gien, and the preponderance of the evidence establishes that a person of ordinary skill would have been motivated to make that combination.” slip op. at 69

      “A sufficient written description of a genus requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can “visualize or recognize” the members of the genus. Ariad, 598 F.3d at 1350; D Three Enterprises, 890 F.3d at 1048–50; Idenix v. Gilead Sciences, 941 F.3d 1149, 1164 (Fed. Cir. 2019); ICU Medical v. Alaris, 558 F.3d 1368, 1377 (Fed. Cir. 2009); Rivera, 857 F.3d at 1319–21; LizardTech v. Earth Res. Mapping, 424 F.3d 1336, 1346 (Fed. Cir. 2005); Smith & Nephew v. Arthrex, IPR2017-00275, Paper 36, 27–28 (May 2, 2018). Because we have determined that the physical partition embodiment of McCarthy is not a disclosure of virtual machines, a virtualization software layer (or software virtualization layer), or a host operating system, McCarthy does not support the computing domains genus of the ’005 claims. Even if we were to agree that the disclosure in McCarthy of virtual partitions were a disclosure of a type of virtual machine (we do not), we would nevertheless determine that the full scope of the computing domains requirement was not met. The virtual machine embodiment claimed in the ’005 patent describes the distinctive features of the virtual machine embodiment, not present in the physical partition embodiment: Virtualization software typically executes in connection with a host operating system of the physical server. The virtualization software creates virtual resources as software constructs. The virtual resources are then assigned to virtual machines. Specifically, the virtual resources are used to execute “guest” operating systems that execute on top of the host operating system. . . . . [V]irtualization refers to the creation of virtual machines that coexist on one or several physical servers. Virtualization software typically executes in connection with a host operating system of the physical server. The virtualization software creates virtual resources as software constructs. The virtual resources are then assigned to virtual machines used for respective servers. Specifically, the virtual resources are used to execute “guest” operating systems that execute on top of the host operating system. The guest operating systems are then used to execute applications. Ex. 1001, 1:39–45, 13:43–51. This arrangement of “guest” operating systems operating “on top of the host operating system” using “virtualization software” is not present in the physical partition embodiment of the ’005 patent or McCarthy.17 Therefore, McCarthy neither discloses a representative number of species falling within the scope of the computing domains genus, nor structural features common to the members of the computing domains genus so that one of skill in the art can “visualize or recognize” the members of the genus. d) Summary Accordingly, having considered the entire record and weighed the entirety of the evidence, we determine that Petitioner has proved by a preponderance of the evidence that McCarthy is prior art to the ’005 patent claims.18” slip op. at 60
