      “information presented in the petition . . . 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). Having considered the arguments and evidence presented by Petitioner and Patent Owner, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on at least one of the challenged claims of the ’554 patent. We do not institute inter partes review as to the challenged claims of the ’554 patent.” slip op. at 2

      “Petitioner argues that a person of ordinary skill in the art (POSITA) “would have had a bachelor’s degree in an academic area emphasizing computer science (i.e. computer science, computer information systems, computer engineering, etc.) or cybersecurity, with at least two years of experience in the field of cybersecurity.” Pet. 6 (citing Ex. 1003 ¶ 49). Petitioner further argues that “additional education or experience might substitute for these requirements.” Id. Patent Owner does not contest Petitioner’s proposed definition of a POSITA at this stage of the proceeding. See generally, Prelim. Resp. For purposes of this Decision, we adopt Petitioner’s proposed level of ordinary skill because it is consistent with the level of skill in the art at the time of the invention as reflected by the ’554 patent and the cited prior art.” slip op. at 7

Patent Owner asserts that “[n]o constructions are necessary to deny institution because denial is warranted for numerous reasons that do not depend on claim construction, as further detailed below.” Prelim.

    • BurdenNot shown unpatentable

      “Having reviewed the record presently before us, we agree with Patent Owner. Limitation 1[d] requires generating “insights, wherein the generated insights include at least a list of abnormal connections between the identified network objects.” The ʼ554 patent states that “[n]etwork insights are natural-language representations of aspects of the network graph.” 1 Ex. 1001, 10:15–17. Petitioner acknowledges that the recited “insights” are “natural-language representations.” Pet. 26 (citing Ex. 1001, 10:16–18). Dr. Easttom also agrees that insights are natural-language representations. Ex. 1003 ¶ 100 (testifying that “Shivamoggi’s insights are provided to the user as textual descriptions (i.e. natural-language representations).”). As an 1 The parties do not address whether the “wherein” clause of limitation 1[d] runs afoul of the printed matter doctrine. “[T]he petition must set forth . . . . [h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104. Even though “insights” are described in the ʼ554 patent as “natural-language representations of aspects of the network graph” (Ex. 1001, 10:15–17), Petitioner does not construe “insights, wherein the generated insights include at least a list of abnormal connections between the identified network objects,” as “printed matter” that may be disregarded because it is “not functionally related to the substrate.” See Praxair Distribution, Inc. v. Mallinckrodt Hosp. Prods. IP Ltd., 890 F.3d 1024, 1032 (Fed. Cir. 2018) (“‘Where the printed matter is not functionally related to the substrate, the printed matter will not distinguish the invention from the prior art in terms of patentability.’. . . For example, in In re Ngai, 367 F.3d 1336, 1339 (Fed. Cir. 2004) there was no functional relationship between claimed instructions and a diagnostic kit, as the instructions ‘in no way depend[ed] on the kit, and the kit [did] not depend on the’ instructions.” (quoting Ngai, 367 F.3d 1336, 1339 (Fed. Cir. 2004)). Because the parties have not addressed it, we decline to consider if the printed matter doctrine applies here. “virtual machine one to load balancer five, where port eighty is routed to port 1337 on virtual machine one, then from load balancer five to firewall two, where port eighty of firewall two is open, then from firewall two to subnet sixteen, where subnet sixteen has a network address of 10.0.1.0/24, then from subnet sixteen virtual network ten, where virtual network ten has a network address of 10.0.0.0/16, then from virtual network ten to virtual network eleven, via peering connection twelve, where peering connection twelve includes a routing rule to virtual network twelve, specifying virtual network twelve's network address, where virtual network twelve's network address is 172.31.0.0/16.” Ex. 1001, 10:31–45 (quotation marks in original). This example illustrates that an insight is provided in natural-language, or textual, format, consistent with the description of an insight in the ʼ554 patent and the testimony of Dr. Easttom. The limitation, which recites “the generated insights include at least a list of abnormal connections,” therefore requires generating a naturallanguage representation of a list of abnormal connections.” slip op. at 18

      “The Board has recently clarified that “[s]imply noting that the petitioner is adopting a patent owner’s claim construction proposals from district court . . . is not a sufficient reason for advancing different positions in the two forums.” Revvo Techs., Inc. v. Cerebrum Sensor Techs, Inc., IPR2025-00632, Paper 20, 5 (PTAB Nov. 3, 2025) (precedential). In Revvo, as in this case, the petitioner did not propose its own constructions for claim terms in the Petition, but instead accepted the patent owner’s proposed constructions from the related district court litigation. Id. at 2. Although the petitioner had proposed different constructions for the claim terms in district court, it did not explain why it was taking a different position before the Board. Id. The Board’s trial rules “do not necessarily prohibit petitioners from taking inconsistent claim construction positions before the Board and a explain why alternative positions are warranted.” Revvo, Paper 20, 3–4 (quoting Cambridge Mobile Telematics, Inc. v. Sfara, Inc., IPR2024-00952, Paper 12 at 8–9 (PTAB Dec. 13, 2024) (informative)). Petitioner has not sufficiently done so here. Moreover, the fact that Petitioner cannot raise its indefiniteness challenge in an inter partes review is not a sufficient reason to allow Petitioner to take inconsistent claim construction positions before the Board and the district court. Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025- 00340, Paper 18, 3 (Nov. 5, 2025) (informative). As explained in the Board’s Tesla decision: Petitioner’s statement that it cannot raise indefiniteness challenges in an inter partes review is not a sufficient explanation. Indeed, the statement amounts to an assertion that a petitioner should be permitted to raise inconsistent invalidity challenges in the two forums. Petitioner’s explanation may have risen to a sufficient level, for example, if Petitioner had shown that, notwithstanding the alleged indefiniteness of the claim term, an ordinarily skilled artisan would understand that the asserted art satisfies the claim limitation (such as if the limitation prescribed a range and only the outer bounds of the range were unclear). Instead, Petitioner argued indefiniteness in the district court and then adopted Patent Owner’s plain and ordinary meaning construction from the district court litigation in its Petition.

      “support a construction that is similar to Petitioner’s construction of a “network path” as “a link between two machines.” See Pet. 17. That is, limitation 1(a) recites “selecting a reachable resource having a network path to access the reachable resource, wherein the reachable resource is a cloud object . . . having access to an external network which is external to the cloud computing environment,” and limitation 1(b) recites “actively inspecting the network path to determine if the network path of the reachable resource is accessible from the external network.” This plain language shows that a network path is simply a connection (link) between an external network object and a resource in a cloud (or cloud object). The specification provides an example of accessing “port 22”: “Active inspection allows to [sic] generate instructions directed at the reachable resource over a network path, which when received by the reachable resource cause the reachable resource to send a response.” Ex. 1001, 5:40–45. The specification also states that “a network path may include sequential representations of possible data/control flows between two or more objects in a graph.” Ex. 1001, 12:49–52; accord Ex. 1001, 12:60–62 (describing “a path show[ing] a connection between security objects and/or computing objects that communicate over a network”), 12:42–44 (“A network path is a connection of two or more security objects accessible from an external or internal network, and/or an external or internal object.”). In other words, the specification indicates that a transmitting testing object may be an object external to the cloud connected via a network path to another object (a cloud resource for testing). The “network path” may also include resources/objects (represented as graph vertices) on the path. See id. at 12:51–59 (“A path may be a vertexonly path, describing a sequence of vertex-to-vertex ‘hops,’ an edge-only path, describing only the edges included in the sequence without description of the associated vertices, or a combined edge-vertex path, describing both edges and vertexes included in the sequence.” (emphasis added)). Accordingly, for purposes of institution, we construe a “network path” as “a connection between an external object and a cloud resource, wherein the connection itself include objects and/or cloud resources.”” slip op. at 9

      “We agree with Petitioner. The evidence of record, including the ’892 patent and its prosecution history,9 indicates that the ordinary and customary meaning of “transitioning . . . from . . . to” encompasses both direct and indirect transitions. Looking first to the claim language itself, the word “directly” appears in claims 1, 6, and 10, but not claim 14, presumptively suggesting that claim 14 was intended to more broadly capture systems with either direct or indirect transitions. See CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed.

      “ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34. On this preliminary record, we are persuaded that Petitioner has made a sufficient showing that a POSITA would have had a reason to combine the teachings of Ericsson and TS 25.331.” slip op. at 20

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner, relying on the testimony of Dr. Kakaes, contends that a person of ordinary skill in the art (POSITA) “would have had a B.S. in Electrical Engineering or a related field with at least three years of experience designing, developing, and/or testing telecommunication systems,” and “would also have familiarity with the wireless standards and well-known protocols for accessing wireless networks existing at the relevant time,” wherein “[m]ore education may supplement practical experience or vice versa.” Pet. 12–13. At this stage in the proceeding, Patent Owner does not contest Petitioner’s proposal or offer an alternative. On this record, we are persuaded that Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art. For purposes of this Decision, we adopt Petitioner’s proposed level of skill.” slip op. at 10

      “proposed combination of Leaning and Gamble teaches all limitations of claims 2 and 9. I find that the added analysis for these claims based on Gamble overcomes the deficiencies in the other ground, including those of the base claim from which they depend. I also differ from my colleagues in how I view secondary considerations of nonobviousness. I find that the developed record of this case does not support that multiple TCP connections or multiple, parallel/simultaneous TCP connections are critical, unclaimed features of the ’772 patent. Indeed, Petitioner does not argue as much, and all challenged claims at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet. Reply 21–22) that Patent Owner cannot credibly maintain that it is entitled to a presumption of nexus to the same products— the MOVE Media Player and “Sling TV”—across nine patents and 120 claims having different scope while citing to substantially the same alleged evidence of secondary considerations. The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances. In addition, Patent Owner’s own cited evidence suggests that MOVE’s plug-in is a “key” feature of its technology, particularly to ensure “fluidity of playback” (PO Resp. 51–52 (quoting Ex. 2048) (emphasis omitted)), but the claims do not recite a plug-in. This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims. I also agree that Patent Owner’s evidence of secondary considerations is entitled to insignificant weight, or little to no weight, and that it does not outweigh Petitioner’s persuasive obviousness showing under the other Graham factors. Thus, I join in my colleagues’ determination that Petitioner has shown, by a preponderance of the evidence, that claims 2 and 9 would have been obvious over the combination of Leaning and Gamble.” slip op. at 101
