      “Ex. 1163 ¶ 37 (citing Ex. 1003 ¶ 71; Ex. 1005, 1–3). We credit Dr. Bajaj’s testimony which is unrebutted and supported by the record. We, thus, agree with Dr. Bajaj’s reasoning which is based on Menon. We further agree with Dr. Bajaj’s conclusion that Menon does not teach away from the combination with Trefethen. Id. ¶ 75. Menon’s description of building on and enhancing the teachings of Trefethen—the earlier work of the same research group at Cornell—by adding MEX routines to achieve high-performance parallel computing and extensibility for MATLAB, demonstrates a classic motivation for a POSITA to combine. RS6000 is specifically referenced in Menon-Trefethen and adds operational details of the parallel operating platform that teach a POSITA how to implement the MultiMATLAB system with a reasonable expectation of success. Considering Menon as a whole, these facts are inconsistent with Patent Owner’s teaching away arguments. For these reasons, Patent Owner’s teaching away argument is unavailing.

      “skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Patent Owner argues that Menon teaches away from a combination with Trefethen because “Menon expressly states that Trefethen’s first-generation architecture is inadequate for the objectives that motivated the newer design.” Resp. 35–37. The evidence does not support Patent Owner’s position. First, Patent Owner’s teaching away argument is inconsistent with the strong evidence of a motivation to combine Menon and Trefethen discussed above. Second, Patent Owner’s teaching away argument is contrary to the evidence of record for the reasons given in Petitioner’s Reply. Reply 13–15 (e.g., “Menon explicitly cites Trefethen and explains that Menon builds on the teachings of Trefethen.”) (citing Pet. 22; Ex. 1003 ¶ 70; Ex. 1005, 1–3; Ex. 1163 ¶¶ 47–53). We are further persuaded by Dr. Bajaj’s reply testimony: the “MultiMATLAB teachings in Trefethen. In fact, Menon describes enhancing the system of Trefethen. For example, Menon describes a list of “goals” already achieved by MultiMATLAB and then states that the architecture has been “redesigned to achieve two further goals.” One of these two “further goals” is “extensibility,” which Menon achieves by its description of adding “MEX routines” to the system of Trefethen. Far from showing an “incompatibility” between Menon and Trefethen as the POR argues, Menon’s addition of the “MEX routines” to MultiMATLAB shows that such a modification was within the capabilities of a POSITA, because the authors of the Menon paper actually implemented the modification. Ex. 1163 ¶ 49 (citing Ex. 1005, 1–3). Dr. Bajaj’s testimony is unrebutted, credible, and supported by the record. We agree with Dr. Bajaj’s reasoning, which is based on direct quotes in Menon. We further agree with Dr. Bajaj’s conclusion that Menon does not teach away from the combination with Trefethen. Id. ¶¶ 50–52. Menon’s description of building on and enhancing the teachings of Trefethen—the earlier work of the same research group at Cornell—by adding MEX routines to achieve high-performance parallel computing and extensibility for MATLAB, demonstrates a classic motivation for a POSITA to combine the teachings of Menon and Trefethen. RS6000 and POEref are specifically referenced in Menon-Trefethen and add operational details of the parallel operating platform that teach a POSITA how to implement the MultiMATLAB system with a reasonable expectation of success.

      “processor,” “multi-core” processor, or “singular ‘hardware processor’ that ‘comprises’ (or ‘with’) multiple ‘processing cores’” as Patent Owner contends. Resp. 11–12, 21; see also Ex. 1163 ¶ 22 (“The claim does not recite ‘single chip,’ ‘single package,’ ‘single die,’ or ‘single multi-core microprocessor.’”). Nor do the claims recite a plurality of processing cores “within” a single-chip package or read as “multi-core within a processor” as argued by Patent Owner. Resp. 12–14; Sur-Reply 2; see Reply 6 (citing Ex. 1163 ¶ 23 (“Thus, the phrase ‘with a plurality of processing cores’ identifies the required processing resources associated with the hardware processor; it does not import a packaging limitation.”)). The claims do recite a hardware processor “with” a plurality of processing cores; a critical distinction even Patent Owner reads as open-ended, i.e., as a hardware processor that “comprises” a plurality of processing cores. See Resp. 11 (“the claims require a singular ‘hardware processor’ that ‘comprises’ (or ‘with’) multiple ‘processing cores’”). Consequently, the claim language does not support Patent Owner’s proposed construction of “a . . . hardware processor with a plurality of processing cores” as a single multi-core processor. cores it contains” in reliance on a parsed description in the ’034 patent specification: The specification explains: “Each processor can contain one or more processor cores that are capable of single-threaded execution. Processor cores are generally independent microprocessors, but more than one can be included in a single-chip package.” Id. at 1212 (partially quoting Ex. 1001, 5:11–16); Sur-Reply 2. The quoted description does not support Patent Owner’s contention that the claimed “a . . . hardware processor with a plurality of processing cores” must be limited to a “single multi-core processor” that “locates multiple cores within a ‘single-chip package,’” i.e. limited to a single multi-core microprocessor such as “a Core 2 Duo is one processor package with two cores.” Resp. 12– 13, 21 (citing Ex. 1001, 7:15–25). The description quoted above from column 5, moreover, describes a “processor” that “can contain one or more processor cores” each of which can be an independent microprocessor. Reply 2–3 (citing Ex. 1001, 5:11–16; Ex. 1163 ¶¶ 10–14). As Petitioner emphasizes, the specification distinguishes a “processor” from a “microprocessor” and describes a “processor” that “can be one or more general purpose single-core or multi-core microprocessors,” rather than limiting a “processor” to a single multi-core microprocessor.

      “A POSITA would have had an especially strong reason to read these references together because they address the same project, the same MATLAB-based parallel-computing problem, and the same MultiMATLAB command environment. Menon expressly identifies Trefethen’s MultiMATLAB work and then describes a redesigned architecture that preserves the same user-level objective––parallel MATLAB computations—while improving implementation details and extensibility. A POSITA therefore would not view the references as mutually exclusive alternatives. Rather, a POSITA would understand Trefethen as teaching specific MultiMATLAB commands and examples, including Eval, Send, Recv, and the architecture was implemented and improved in a later version. Ex. 1163 ¶¶ 71–72 (emphases added). We find the above reasoning persuasive and adopt it as our own. Petitioner and Dr. Bajaj demonstrate a sound technical motivation for a POSITA—someone having a bachelor’s degree in computer science, computer engineering, or electrical engineering and two years of experience working in the field of cluster computing or parallel processing—to combine Menon and Trefethen: to improve MATLAB’s operational performance and extensibility in a parallel operating environment. Menon builds on Trefethen to improve and extend the parallel processing capabilities of MultiMATLAB: “This system will enable users to access high-performance parallel routines from within the MATLAB environment, to extend the environment with new parallel routines, and to use these routines to develop parallel applications with the MATLAB language.” Ex. 1005 Abstract. Menon is intended to be read in conjunction with Trefethen, as would be expected from two references generated by the same research group at the same university addressed to the same technical subject matter about a year apart. Ex. 1005, 1; Ex. 1006, Ex. 1086 ¶¶ 65, 101, 102. The very first citation in Menon is to Trefethen. Ex. 1005, 2, 16.” slip op. at 30

      “operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318).

Pet. 7–8 (citing Ex. 1001, 2:14–17, 4:7–14, 9:3–6; Ex. 1003 ¶¶ 67–68). As above, whether we construe the “[external] data exchange device” under 35 U.S.C.

Patent Owner, quoting the description of a data exchange device in the ’294 patent, contends that a “[external] data exchange device” “can be any sort of data exchange device comprising an electronic circuit (not shown) therein and a data transceiver 9a.” Resp. 8 (quoting Ex. 1001, 9:4–6). Patent Owner also responds to the Petition by clarifying that “[a]n external data exchange device is not a transceiver but a device with a transceiver.” Id. (citing Ex. 2001 ¶ 48). Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)).

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “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). These disclosures demonstrate that Petitioner’s motivation to combine stems from the prior art references themselves rather than from hindsight. Moreover, Petitioner’s contentions are supported by credible testimony from Dr. Easttom. 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. Patent Owner does not provide any authority supporting its contention that providing a motivation to combine in the manner asserted in the Petition is contrary to proper obviousness analysis under Graham.” slip op. at 25

      “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. We find Petitioner’s formulation to be consistent with the evidence of record at this stage of the proceedings, including the asserted prior art and the ’529 Patent, and we preliminarily adopt and apply that definition for purposes of this Decision.

      “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. See Ex. 1005, 15, 25.” slip op. at 19

      “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

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

      “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
