    • Skill levelSkill level petitioner adoptedDecided for patent owner

      “Patent Owner asserts that: A person of ordinary skill in the art in the field of the ’781 patent would have been a person with at least a bachelor’s degree in Electrical Engineering, Computer Engineering, or equivalent, and at least two years of prior work experience with computer architecture, including experience relating to fault tolerant computer architecture, as of the earliest priority date of the ’781 patent—October 25, 2004. If a person did not have a bachelor’s degree, additional relevant and practical experience with fault tolerant computer systems could provide an acceptable substitute. Likewise, further education beyond a bachelor’s degree could compensate for a deficiency in practical experience. See EX2004, Declaration of Nigel A. Jones (“Jones”), ¶ 26. PO Resp. 3. Patent Owner further notes that its position is “similar, but not identical to, Petitioner’s [position]” but that “the analysis [of the claims] is identical for both proposed determinations.” Id. We agree that our analysis would not differ based on choosing one proposed level of skill over the other, but as the losing party, we select Petitioner’s proposed level of skill.” slip op. at 20

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “Accordingly, based on our analysis of the claims and specification, we determine that “logic . . . for transferring, during system runtime, the role of boot processor” means logic that causes the system to identify the spare processor as the boot processor (e.g., in a device tree) which then causes the spare processor to appear as the boot processor to the system during runtime. Ex. 1001, 5:39–55, 10:43–67 (describing why boot processors are treated differently even after the boot process has completed); compare id. at 9:37– 10:42 (process for recovering from loss of lockstep of a non-boot processor without using a spare), with id. at 10:43–11:42 (process for recovering from loss of lockstep of a boot processor using a spare because boot processors, during runtime, need special treatment); see also 15:21–42 (emphasizing that spares are only needed for recovering boot processors). We construe transferring a “role of boot processor” to mean transferring an identification in the system of which processor is the boot processor. This construction comports with the embodiments described in the specification. We do not adopt an additional requirement that this procedure also requires designating which processor will boot the system in the next reboot, which is not disclosed in the specification.” slip op. at 26

    • Expert testimonyPetitioner expert discountedDecided for patent owner

      “Based on the clear support in the specification for the above interpretation, we see no need to resort to extrinsic evidence. Seabed Geosolutions (US) Inc. v. Magseis FF LLC, 8 F.4th 1285, 1287 (Fed. Cir. 2021) (“If the meaning of a claim term is clear from the intrinsic evidence, there is no reason to resort to extrinsic evidence.”) (citing Profectus Tech. LLC v. Huawei Techs. Co., 823 F.3d 1375, 1380 (Fed. Cir. 2016) (“Extrinsic evidence may not be used ‘to contradict claim meaning that is unambiguous in light of the intrinsic evidence.’” (quoting Phillips, 415 F.3d at 1324)). In general, the cited portions of testimony from the declarants from both parties in the briefs do little more than point to the portions of the ’781 patent described above or argue about what a boot processor does during booting. See, e.g., Pet. Reply 2–8. The specification makes clear that it is focused on the role of boot processor during runtime because of problems encountered during runtime; it is not focused on the boot processor during booting. Ex. 1001, 5:39–55, 10:43–67. Thus, the testimony about what a boot processor does during booting, or that the primary function of the boot processor is to boot, is not particularly pertinent, and does not undo the unambiguous discussion in the ’781 patent.” slip op. at 27

    • BurdenDecided for patent owner

      “whether they are the boot processor or not (Ex. 1008, 238, 710), Petitioner does not explain how such information is exposed to the BIOS or operating system, nor how it is changed during runtime, after its purpose has been fulfilled. In sum, even if Petitioner’s proposed combination swaps the spare processor for the processor that booted the system, Petitioner’s proposed combination does not appear to transfer the role of boot processor to the spare processor. At best, Petitioner’s proposed combination transfers the tasks of one processor to another. See Ex. 1005 ¶¶ 15 (Fox describing its disclosure as “updat[ing] the ‘active’ processor list” and “[re-]allocat[ing] the threads that were running on the failing processor”), 46 (transferring “processes (instructions, threads, etc.) initially allocated to the failing processor” to the spare processor)). Of the art of record, we are only aware of the ’781 patent transferring a designation of which processor is the boot processor during the swap to a spare processor. See, e.g., Ex. 1001, 10:43– 55, 11:10–12, 16:19–21, 17:51–55; claims 1, 9, 16, 25. In conclusion, we find that Petitioner has not shown, by a preponderance of the evidence, how the prior art teaches “transferring” a “role of boot processor” as required by limitation 1[c].” slip op. at 40

Petitioner makes additional contentions about what a POSITA would have understood. Id. (“A POSITA would understand that all types of cameras (e.g., analog and digital, photo and video) generally involve the same lighting considerations . . . . [and] that it is important to provide light that evenly illuminates the target subject or object to minimize reflected glare and shadows.”). Patent Owner contends that a POSITA would have at least: (a) a bachelor’s degree in electrical engineering, optical engineering, or a related field; (b) two years of practical experience in designing and developing lighting systems, particularly those integrated with electronic devices such as webcams or computer monitors; and (c) knowledge of user-interface considerations for consumer electronics . . . . Additional experience can substitute for education and vice versa. Prelim. Resp. 12 (citing Ex. 2036 ¶ 48). Patent Owner disputes Petitioner’s contentions regarding what a POSITA would have understood. Prelim. Resp. 12–13 (“[O]ne of ordinary skill in the art would have understood that analog and digital cameras have different operating principles and lighting requirements [and] Petitioner’s lack of appreciation for the suitability and unsuitability of different lights for different applications infects and dooms its invalidity analysis.” (citing Ex. 2036 ¶¶ 36–47)). and years of experience required for a POSITA.

      “sufficiently established a motivation to combine Ross, Agarwal, and Biran in the manner proposed. For example, Petitioner contends for limitation 1[b] that a POSITA would have been motivated to implement Ross’s system to genericize network entities as taught by Agarwal and that Agarwal provides an express motivation to do so, explaining that “[t]he grouping of nodes can be helpful when attempting to understand system properties in a cloud environment, like availability, security and performance, where the system includes a large number of nodes.” Pet. 21 (citing Ex. 1005, 4:13–26, 13:21–27; Ex. 1003 ¶¶ 103–108). Similarly, for limitation 1[d] Petitioner argues that “Biran provides express motivation to implement Ross to gather information on host-less components . . . to generate an accurate, service-aware view of the system infrastructure.” Id. at 32 (citing Ex. 1006, 1:59– 61; Ex. 1003 ¶¶ 134–136).

See Ex. 1003 ¶¶ 103–108, 122–123, Addressing a motivation to combine on a limitation-by-limitation basis, as Petitioner has done in its Petition, is not necessarily improper, and may in fact be more suitable in certain situations depending on the proposed combination.

      “35 U.S.C. § 103 involves determining the level of ordinary skill in the pertinent art at the time the invention was made. Graham, 383 U.S. at 17. The level of skill in the art is “a prism or lens” through which we view the prior art and the claimed invention. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). The person of ordinary skill in the art is a hypothetical person who knows the relevant art. In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). Factors to consider include the types of problems encountered in the art, the sophistication of the technology, and the educational level of active workers in the field. Id. One or more factors may predominate. Id. Petitioner asserts that one of ordinary skill in the field of the ’529 Patent would have had “a bachelor’s degree in computer engineering, computer science, electrical engineering, or a similar degree, with 2–3 years additional education or experience might substitute for these requirements.” Pet. 5; Ex. 1003 ¶¶ 32–33. Patent Owner’s Preliminary Response does not address this issue.

      “Owner contends that Petitioner’s argument “inverts the appropriate understanding: just because the challenged patent identifies an example security database that stores a representation of a computing environment as nodes and edges does not mean that anything that stores a representation of a computing environment as nodes and edges is necessarily a security database.” Prelim. Resp. at 7–8. We agree with the logic of Patent Owner’s argument, but disagree that Petitioner necessarily “relies on this inverted understanding for its prior art mapping.” Id. at 8. We understand Dr. Zadok’s explanation to mean only that the claim term “security database” encompasses graph databases that include a representation of the computing environment, meaning that some (but not necessarily all) security databases are graph databases. See Ex. 1003 ¶ 100. The language in the Petition to which Patent Owner objects can be read consistently with Dr. Zadok’s declaration. Petitioner does not, however, take a position on what the outer bounds of the claim term “security database” should be. Without attempting a full construction of the term “security database,” it is possible to determine from the current record, at least on a preliminary basis, some of the database types that would fall within its scope. The ’529 Patent explains that the claimed “security database” is part of an “inspection cybersecurity threats. Specifically, it provides as follows: In certain embodiments, the cloud computing environment 110 is monitored for cybersecurity objects, threats, risks, and the like, by an inspection environment 130. In an embodiment, the inspection environment 130 is configured to monitor the cloud computing environment 110 for cybersecurity objects, threats, risks, combinations thereof, and the like. Ex. 1001, 6:1–7; see id. Fig. 1. The ’529 Patent also provides: “In an embodiment, the inspection environment 130 further includes a security database 136. In some embodiments, the security database 136 is configured to store a representation of the cloud computing environment 110, for example based on a predetermined data schema.” Id. at 7:46–50. Thus, we can conclude that the term “security database,” as used in the ’529 Patent, encompasses at least a database within an inspection environment that monitors for cybersecurity threats and is configured to store a representation of a cloud computing environment that is monitored by the inspection environment. An example of such a security database is the Neo4j® graph database. Id. at 7:58–60. As discussed below, another example is the “context map” disclosed in Shua ’048.

      “We find nothing contradictory in Petitioner’s argument that “100% of an organization’s assets” would include its AI models. Pet. 11, 21. Shua ’048 appears to contemplate treating multiple layers of structures as assets to be mapped and monitored. Ex. 1005 ¶ 30 (Shua’s Orca system “automatically assesses the security state of discovered asset[s] throughout the technology stack, including all four cloud layers: I/S, OS, apps, and data.”). On the current record, a VM is an asset that contains other assets, including an AI model.10 We conclude that for the purposes of institution, Petitioner’s mapping, as elucidated by Dr. Zadok, adequately demonstrates that the combination of Shua and Lang discloses limitation 1[c] and the corresponding limitations in claims 9 and 10. We further conclude that Petitioner’s identification of a motivation to combine Shua with Lang is adequate for institution purposes.” slip op. at 23

      “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

      “The ’655 patent Specification states that: The topology data table 21 of the online server 20 is mainly recorded with a link data 49 between each of the P2P devices 41– 46 within the P2P device community.

Ex. 1001, 4:51–57. On this preliminary record, we agree with Petitioner that the term “link data” is a “connection relationship between the P2P devices.” This meaning is consistent with the ordinary meaning of the term within the context of the claim, that is, “link data” means data on the links (connections) between each of the P2P devices, where the Specification provides a more fulsome meaning that the term includes, at least, “the connection structure, connection data and/or locations of connection.” See id. at 4:55–57.

We determine that this disclosure provides support for Mr. Lett’s testimony that “Lee describes techniques for changing an overlay in response to changing network characteristics,” which could be beneficial.
