      “would have had a bachelor’s degree in a pertinent discipline, such as electrical engineering, civil engineering, mechanical engineering or equivalent with 2–3 years of experience in electrical utility systems, planning, and design” and “the number of years of experience could be higher or lower given the level of education and vice versa.” Pet. 23. In its Preliminary Response, Patent Owner contended Petitioner’s level of ordinary skill is too high. Prelim. Resp. 32. According to Patent Owner, a POSITA would have had “an associate degree in an engineering discipline, and 1–2 years’ experience in electrical power systems” and “[a] lack of work experience can be remedied by additional education, and vice versa.” Prelim. Resp. 31 (citing Ex. 2001 ¶ 21).

Based on the full record, we determine a POSITA would have had a bachelor’s degree in an engineering discipline and two years of experience in electrical power systems. We are satisfied that this comports with the level of skill necessary to understand and implement the teachings of the ’291 patent and the asserted prior art. See Okajima v.

      “the cable hangers (which support the current wires, data wires and other wires). That is, a single multi-function line supports the cable hangers, as a messenger wire, and provides a current path, as a grounding conductor.” Ex. 1001, 2:33–37 (emphasis added). And the sentence following that passage, which is cited by both parties, states: “Accordingly, as used herein, a ‘multi-function line’ means a tension member that supports current wires and/or cable hangers, and, which is conductive.” Ex. 1001, 2:37–40 (emphasis added). The sentences immediately following that sentence provide additional context, stating: “That is, a messenger wire is not a ‘multi-function line.’ Similarly, a conductor that does not support other constructs is not a ‘multi-function line.’” Ex. 1001, 2:40–42 (emphasis added). Thus, the specification indicates that a multi-function line is a tension member, “is conductive,” and supports other constructs such as current wires and/or cable hangers. In contrast, the specification does not mention “effective ground fault current path.”” slip op. at 10

    • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner

      “First, we agree with Petitioner that Patent Owner has not shown that the cited products are coextensive with, and have the required nexus between, the products and claim 1. See Reply 18–29. Even if Patent Owner sells an “Integrated Grounding System” that satisfies each limitation of claim 1, that system is undeniably comprised of “various” “exemplary” interchangeable parts that have uses outside of the claimed invention, that at least purportedly relate to many other of Patent Owner’s patents, and that were known in the prior art. E.g., Ex. 2064, ¶ 304 (identifying “exemplary” product part numbers, including CAB-9605, CAB-9705, CAB-9760, and CAB-9607), n.10; App’x A, A5 (identifying a part number “representative” part the “mid-pier kit”); Ex. 1049, 6–7 (identifying Patent Owner’s patent’s relating to different part numbers). For example, Patent Owner identifies two patent numbers purportedly protecting its “grounding Mid Pier Kit,” the ’551 patent and US Pat. No. 10,461,518. Ex. 1049, 6–7. Patent Owner identifies three of its patents as protecting its copper messenger wire, part number CAB-9605: (i) the ’551 patent, (ii) US Pat. No. 10,461,518, and (iii) US Pat. No. 10,811,859. Id. And Patent Owner identifies eight different patents, but not the ’551 patent, as protecting the cited cable hangers, CAB- 9760. Id. And as explained in the analysis above, all of these parts were known and available in the prior art, as evidenced by the CAB Website and the CAB Whitepaper. We can discern no nexus between the features of the ’551 patent and the alleged objective evidence of nonobviousness given that the so-called “Integrated System” includes multiple, interchangeable, and “exemplary” part numbers that were known in the prior art. See Yita LLC v. MacNeil IP LLC, 69 F.4th 1356, 1364 (Fed. Cir. 2023) (“But our case law makes clear that objective evidence of nonobviousness lacks a nexus if it exclusively relates to a feature that was known in the prior art—not necessarily well-known.” (internal quotations and citations omitted)); see also Tokai Corp. v. Easton Enters., Inc., 632 F.3d 1358, 1369 (Fed. Cir. 2011) (“If commercial success is due to an element in the prior art, no nexus exists.”).” slip op. at 21

      “We find Petitioner’s proposed construction to be generally consistent with the intrinsic record (including the claim language) and the Federal Circuit’s guidance. However, we decline to adopt the use of “related to” instead of “associated with” in Petitioner’s proposed construction because we determine the language used in the claim, “associated with,” is clear enough on its face and Petitioner provides no persuasive justification for altering the plain meaning to “related to”. Consistent with the Federal Circuit’s guidance, we determine the proper construction of “performance data” further includes data pertaining to the performance of a server and/or a technology tier. Netflix, 2024 WL 3507601 at *6 (citing Ex. 1001, 3:56–57, 4:3–8, 4:14–18, 7:26–29). Accordingly, we determine “performance data” means “data associated with the performance of one or more application instances, including instance-level, application-level, device-level, and tierlevel data and includes data pertaining to the performance of a server and/or a technology tier.” We determine no other terms require express construction. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “Applying our construction of “performance data,” we agree with Petitioner that, among other things, the CPU utilization and review time shown in Masters’ Figure 5.6.2.1-2 and Figures 8A and 8B fall within the scope of the claimed “performance data.” See Pet. 50–56; Reply 17. The CPU utilization data and review time data are both data associated with the performance of one or more application instances. Further, the Figures and corresponding description in Appendix J evidence collection of the performance data for each application instance. Pet. 34–38, 50; Ex. 1024, 39. Similarly, the startup of a copy of the Auto-Special process on Altair11 constitutes a life cycle event, as it is the creation of an application instance, and the termination of Auto-Special on Altair7 is another example of a life cycle event, as claimed. Ex. 1024, 39; see Pet. 39–44. We agree with Petitioner that these Figures and related descriptions in Masters teach collecting performance data and correlating the performance data to the life cycle events. See Pet. 46, 50–55. We also agree with Petitioner that Masters’ Figures 9A and 9B similarly show the collection and correlation of performance data, at least with the response time, action time, CPU score, and similar metrics depicted in the Figures. Pet. 47–49. Figures 9A and 9B show the correlation of the performance data to a life cycle event, by, for example, depicting the performance issue (an overload on Altair11) that cause the creation of a new application instance on Altair3. Pet. Reply 12. We agree with Petitioner that the response time to trigger the creation of an application instance on Altrair3 and the amount of time the application instance takes to start are two examples of performance data correlated with the life cycle event. Pet. Masters, Figures 9A and 9B depict Masters’ Decision Review Display that provides a summary of allocation and reallocation actions taken by the RMA, and “[f]or each action, timing information regarding how long it took the Resource Management functions, e.g., the Resource Manager . . . and the Program Controller . . ., to both arrive at a decision and to enact the decided action are shown along with host fitness scores that were used in arriving at the allocation decision.” Ex. 1004, 30:1–10. We disagree with Patent Owner’s arguments that the Masters’ “response time” “cannot be associated with the performance of the ‘Semi-Auto’ application instance because the response time passes before the instance exists” (PO Remand Br. 4), and we agree with Petitioner that the time required to start an application instance is a metric associated with the creation of that instance. In sum, we agree with Petitioner that Masters teaches the Correlating Limitations.” slip op. at 28

      “In general, a preamble limits the invention if it recites essential structure or steps, or if it is necessary to give life, meaning, and vitality to the claim.” Cochlear Bone Anchored Solutions AB v. Oticon Med. AB, 958 F.3d 1348, 1354–55 (Fed. Cir. 2020) (quoting Catalina Mktg. Int’l v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002)). We agree with Petitioner that the preambles of claims 1 and 6 recite an intended use. The bodies of both claims recite a structurally complete system comprising a messenger wire and a plurality of cable hangers that are disposed along and suspended from the messenger wire and have a plurality of cable carrying surfaces structured to support at least one electrical cable of the plurality of electrical cables and are separated by a cable carrier divider. Ex. 1001, 10:27–37. According to the preambles, the system are used “for organizing a plurality of electrical cables extending from a plurality of solar panels.” Id. at 10:24–26. slip op. at 9

      “Petitioner asserts that Patent Owner’s construction “only replaces ‘organizing’ with ‘separating’” and “organizing” has a broader ordinary meaning than separating and includes “to arrange or order” not merely to separate. Reply 4 (citing Exs. 1052, 1053); id. at 5 (“Separated cables may be organized. But not all organized cables are necessarily separated.”). We adopt Petitioner’s interpretation of “organizing” as “to arrange or order.” Reply 4. This meaning is consistent with the preamble language of “[a] system for organizing a plurality of electrical cables extending from a plurality of solar panels” comprising a messenger wire and cable hangers disposed along and suspended from the messenger wire with cable carrying surfaces that support electrical cables separated by a divider. Ex. 1001, 10:24–37. The system organizes electrical cables by (1) suspending them from a messenger wire on cable hangers, (2) supporting the cables on cable carrying surfaces of each cable hanger, and (3) separating the cables on adjacent cable carrying surfaces of the cable hangers by using a divider. The “organizing” in the preamble encompasses each of these ways of arranging or ordering the electrical cables but is not limited to any particular way of doing so and merely recites an intended use of the systems. Because we interpret the preamble as reciting an intended use of the systems, we also interpret this portion of the preamble as an intended use of those systems. Our Decision would be the same under Patent Owner’s interpretation that organizing means separating because the combination of Almy and Carr renders obvious a system for organizing electrical cables extending from solar panels by suspending them from a messenger wire on cable hangers that also separate the cables, as discussed infra in Section II.D. See Reply 12 n.4.” slip op. at 12

      “Patent Owner argues that a skilled artisan would not have replaced Almy’s wire loops with Carr’s hangers to prevent cross-induction because Almy discloses only DC power cables that extend from the photovoltaic (PV) modules to a combiner box and inverter that converts DC current to AC current without disclosing AC cables or data cables in close proximity to Almy’s DC cables that could create a cross-induction effect.

Pet. 45–46; Reply 12–13; Ex. 2001 ¶¶ 53–55.

Because Almy’s wire loops cannot comply with NEC regulations that require the separation of AC, DC, and data cables, they limit the ability of Almy’s system to power trackers with AC current to move PV modules to track the sun and obtain maximum power. Ex. 1001, 1:20–56; PO Resp. 7–8 (describing the solar industry trend to use trackers and NEC rules requiring separation of AC, DC, and signal cables for such systems). Carr’s hangers would enable Almy’s solar power system to organize AC, DC, and data cables for solar panels and trackers on a single messenger wire to increase efficiency, comply with NEC rules, prevent cross induction, and avoid the costs of trenching and cable trays. Reply 12–13; Pet. 45–47; Ex. 1005, 1:27–34 (Carr’s cable hangers separate arial conducting cables to minimize cross induction); Ex. 1002 ¶¶ 32–36 (describing the benefits of separating electrical cables with hangers), 48, 96–98 (wire loops cannot prevent cross induction between current- and non-current-carrying cables as hangers do); Ex. 2001 ¶¶ 53–55 (NEC rules require separation of AC, DC, and signal cables); see Metso Mins., Inc. v Powerscreen Int’l Distrib., 526 F. App’x 988, 997 (Fed. Cir. 2013) (finding a motivation to combine to create a solution that complies with road permit regulations).

      “We decline to adopt Patent Owner’s implicit construction that would require “selecting an entity pair from” all of the entity pairs of “said plurality of transport entities.” Contrary to Patent Owner’s arguments addressing the claim language, the plain language of claim 1 does not require the selection to be from all of the entity pairs of the plurality of transport entities for which an overall cost has been determined. The plain language of claim 1 also does not preclude the selection to be from a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined. Rather, dependent claim 9, through its dependence on claims 1 and 4, explicitly allows for the selection to be from a subset of the entity pairs of the plurality of transport entities.

      “We also do not agree with Patent Owner’s substantive arguments. We agree with Petitioner that, in the flow of data from the core network to the network nodes 24, 26, 28 in Bruckman, there is a selection of a trace 52 out of the group of four traces 52 in order to send data to the appropriate line card 34, link 30, and node 24, 26, 28. We have reviewed Petitioner’s analysis addressing dependent claim 11 (see Pet. 58–63) and find that this selecting a trace 52 out of the group traces 52. For these same reasons, we also do not agree with Patent Owner’s argument that “given that Bruckman discloses a system in which the trace is ‘determined’—and not selected—by the selection of a link 30, a POSITA would understand that Bruckman does not disclose the claimed selections in ‘a single computation.’” PO Resp. 53. More particularly, the analysis addressing claim 11, cited by Petitioner, provides additional explanation that Bruckman’s equipment 22 is a two-level demultiplexer structure with concentrators 50 acting as a first level demultiplexer to select one of four links 30 and switching core 40 acting as a second-level demultiplexer by distributing data frames from the input channel among four separate traces 52. See Pet. 58–59 (reproducing Ex. 1005, Fig. 2 (with Petitioner’s added annotations); citing Ex. 1003 ¶ 137; Pet. 23–27). The cited analysis further explains that Bruckman’s equipment 22 shown in Figure 2 includes a control line from controller 42 to the switching core 40 and control lines to each of the concentrators 50. See Pet. 59–60 (reproducing Ex. 1005, Fig. 2 (with Petitioner’s added annotations); citing Ex. 1003 ¶ 138). According to Petitioner, “[g]iven this well-known, two-level structure, a POSITA would have found it obvious for Bruckman’s [e]quipment 22 to be controlled in a manner consistent with well-known two-level demultiplexer control techniques.” Pet. 59 (citing Ex. 1003 ¶ 138). The cited analysis further explains that “[b]ecause each of the demultiplexing devices (switching core 40 and concentrators 50) in [Bruckman’s] Fig. 2 has one input and four outputs, a POSITA would have found it obvious to control each with a two-bit command signal.” Pet. 60 (citing Ex. 1003 ¶ 139). According to Petitioner, switching core (second-level demultiplexer) to select a trace 52. A different two-bit signal would be used to control the concentrators (first-level demultiplexers) to select a link 30, consistent with known techniques for controlling two-level demultiplexers.

      “Considering the evidence of record on both sides, we find Petitioner’s argument persuasive that Baker teaches a “mapping” as recited in limitation 1.4. Baker’s disclosure of a “mapping” is explicit. See, e.g., Ex. 1005 ¶ 69, 83. And the evidence shows that this mapping occurs “in advance of a communication,” and may, for example, take place in the head node as part of the Administer Ring routine.

That intermediate rings are ultimately configured to simply forward traffic “according to preconfigured rules” (Ex. 1005 ¶ 87) rather than to perform more complicated routing has no pertinent bearing on the process corresponding to the recited “mapping” step, which occurs “in advance” of the communication and any such forwarding (id. ¶ 76).” slip op. at 26

      “allocating bandwidth as part of its resources and that, in light of Wright, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology. See Pet. 36; Pet. Reply 22–23; Ex. 1007 ¶ 17; Ex. 1003 ¶¶ 94–96; Ex. 1036 ¶¶ 49–51.

See PO Resp. 31–32. Based on the level of ordinary skill and the level of detail in Baker, Wright, and the ’431 patent, and crediting Dr. Houh’s testimony, we find Petitioner’s argument persuasive that such modification would have been within the capability of someone of ordinary skill in the art. See Pet. 17–20 (citing Ex. 1003 ¶¶ 42–46, 48).
