    “Petitioner argues that at the time of the application for the ’986 patent (January 2002), a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering or a related field, plus at least two years of industry experience or graduate-level academic experience with computer networking.” Pet. 20. In the Decision on Institution, the Board agreed with and applied Petitioner’s proposed definition, removing the phrase “at least” to avoid unnecessary ambiguity. Dec. on Inst. 18–19. Patent Owner uses Petitioner’s proposed definition for its Response. PO Resp. 5. Neither party made any further argument regarding the level of ordinary skill in the art in its papers during trial. In the Cisco IPR, we adopted a similar definition, determining that a person of ordinary skill in the art would have had “a bachelor’s degree in computer science, computer engineering, electrical engineering, or in an equivalent field, or approximately two years of experience working in the field of information technology and networking,” where “[l]ack of professional experience can be substituted by additional education, and vice versa.” IPR2024-00505, Paper 29 at 10–11 (alteration in original); see Dec. on Inst. 19 n.7 (noting the proposed definition in the Cisco IPR). Based on the full record developed during trial, including our review of the ’986 patent and the types of problems and solutions described in the ’986 patent and cited prior art, we adopt the same definition of the level of ordinary skill in the art as the Cisco IPR and apply it for purposes of this Petitioner’s similar proposed definition in this proceeding.” slip op. at 12

    “Gai discloses entering an Enable_Uplinkfast command at an access switch (e.g., access switch 114) to block a failed port (e.g., the root port) and configure the access switch to send dummy traffic upstream through a new active port. . . . When modified in view of IEEE 1999’s disclosure that self-healing network traffic can advantageously be sent both upstream and downstream, the command would be entered at a backbone switch (e.g., backbone switch 122) to block a failed port (e.g., a designated port connected to access switch 114) and configure the backbone switch to send dummy traffic downstream to an access switch (e.g. access switch 114) through a new active port. While Gai uses its protocol signaling command, Enable_Uplinkfast, to send dummy traffic through a new root port, [a person of ordinary skill in the art] would deem it an obvious implementation detail to modify the parameters of the port on a backbone switch.

    “In the Cisco IPR, we addressed four claim terms in the final written decision: “access switch” and “edge switch,” which appear in independent claims 1 and 13 and various dependent claims, and “downstream” and “upstream,” which appear in claims 11, 12, 23, and 24. IPR2024-00505, Paper 29 at 11–14. We interpreted “access switch” to mean “a switch with ports that connect to LANs and/or to other network endpoints, such as user computer systems,” interpreted “edge switch” to mean “a core switch that is directly connected to an access switch,” interpreted “downstream” to mean “away from the root switch,” and interpreted “upstream” to mean “toward the root switch.” Id. As noted above, Patent Owner did not appeal that decision. We incorporate herein our previous analysis in the Cisco IPR, but note that none of the analysis of the disputed issues below depends on such determine whether Petitioner has met its burden to prove unpatentability of the challenged claims. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Claims 8, 15, and 20 Claim 8 depends indirectly from independent claim 1. Claims 15 and 20 depend indirectly from independent claim 13, which is similar to claim 1 but recites a network switching device rather than a method. As to independent claim 13, Patent Owner refers to its earlier arguments regarding claim 1, asserting that limitation [13C] is “substantially similar” to limitation [1E]. PO Resp. 14–15.

Specifically, according to Patent Owner, Petitioner proposed that “predetermined” be construed as “determined before the data flow request” and that “quantum” be construed as “an amount of a requested resource by which to increase or decrease.” Id.

    “The most common type of MAC bridge is a switch, which has multiple ports connecting it to LANs, other switches, host computing systems, or other network elements. Switches can be roughly classified as access switches or core switches. An access switch has ports that connect to LANs and/or to other network endpoints, such as user computer systems. Core switches interconnect the access switches into a Wide Area Network (WAN), by direct connection between the core switch and access switches and/or by connection to other core switches. Core switches that are directly connected to access switches are referred to herein as edge switches. Ex. 1001, col. 1, ll. 27–38. Both parties refer to this disclosure when arguing whether particular switches in the asserted prior art (Gai) qualify as an “access switch” or “edge switch.” See Pet. 5, 22, 27–28 (“edge switches are ‘[c]ore switches that are directly connected to access switches’”), 71; PO Resp. 31–32 (“The ’986 patent discloses that ‘[a]n access switch has ports that connect to LANs and/or to other network endpoints.’ . . . The ’986 patent also discloses that edge switches are ‘[c]ore switches that are directly connected to access switches.’”); Reply 20, 22. Dr. Houh and Dr. Olivier do so as well. See Ex. 1003 ¶¶ 39, 66–67, 82–83, 166, 171, 193; Ex. 2001 ¶ 80. Based on the full trial record, we agree and conclude that the descriptions of “access switch” and “edge switch” in the ’986 patent reflect what was understood to be the plain and ordinary meanings of these terms at the time of the invention. Accordingly, we interpret “access switch” to mean a switch with ports that connect to LANs and/or to other network endpoints, such as user computer systems, and interpret “edge switch” to mean a core switch that is directly connected to an access switch.” slip op. at 12

    “and conclude that Petitioner has not shown sufficiently that a person of ordinary skill in the art would have been motivated to designate switch 117 as the root switch when implementing the network reconfiguration method of Gai. The only mention of an access switch connected to port 7 of switch 114 is at column 13, lines 59–63 of Gai. While that sentence establishes that such an access switch may exist in the network, it does not state or imply that it would be the root switch. Instead, when discussing the operation of the Figure 1 network, Gai only identifies switches 120 and 121 as the root switch. See Ex. 1005, col. 10, ll. 37–41, col. 11, ll. 60–64, col. 14, ll. 16–20, col. 15, ll. 27–29, 38–51, col. 16, ll. 42–45. To be sure, Gai does disclose that “execution of the spanning tree algorithm causes the switches to elect a single switch, among all the switches within each network, to be the ‘root’ switch,” where “[e]ach switch has a unique numerical identifier (switch ID) and the root is the switch having the lowest switch ID numeric value,” such that an access switch can be the root switch if it has the lowest switch ID. See Ex. 1005, col. 2, ll. 42–47, col. 10, ll. 29–36. As Patent Owner and Dr. Olivier explain in detail, though, Gai expressly cautions against doing so. Gai discloses that [d]epending on the configuration of a given network, the location of the root can significantly affect the distance that messages must travel. For example, many networks include a plurality of switches designated as access switches that provide connectivity to LANs, end stations, etc., and a plurality of backbone switches that, in turn, interconnect the various access switches. If the root is located at an access switch and the principal server utilized by the end stations (i.e., clients) is coupled to a backbone switch, the average distance between end stations and the primary server may be quite high, resulting in inefficient network operation. In addition, the backbone switches may become partitioned as ports between them are blocked. Id. at col. 3, ll. 17–29; see also id. at col. 10, ll. 26–29 (the “location of the root may affect the average distance (i.e., the average number of hops) a message travels and/or cause undesirable partitioning of backbone switches”). Thus, the location of the root is not an unimportant consideration—it affects the distance messages must travel and can cause backbone switches to be partitioned. See id. Gai, therefore, discloses that “[t]o reduce the average distance and avoid partitioning of the backbone switches, it is desirable to locate the root at a backbone switch.”10 Id. at col. 3, ll. 29–31 (emphasis added). Switch 117 in Petitioner’s modified Figure 1 is an access switch, not a backbone switch. See id. at col. 6, ll. 10–12 (“Access switches are preferably coupled to entities (e.g., LANs, end stations, etc.) whereas backbone switches provide the interconnections between access switches.”).” slip op. at 44

    “We agree with Petitioner. For purposes of claim 1, which does not recite “downstream” communication of dummy traffic (unlike claims 11, 12, 23, and 24), the only modification to Figure 1 is the addition of switch 117 and server 112e—otherwise, in Petitioner’s analysis, Gai’s method operates exactly as described when a failure occurs at root port 3 of switch 114. See Pet. 69–73, 81–85; Tr. 47:20–48:2. That modification is expressly supported by Gai, which discloses the following: Rapid reconfiguration entity 234 similarly generates one or more separate multicast messages 400 for each remaining entity directly coupled to access switch 114 (i.e., entities or end stations on LANs 102–104). In each message 400, entity 234 loads SA field 414 with the address of the corresponding entity. Each of these messages are similarly forwarded by access switch 114 through the new forwarding port (i.e., port number four). In addition, entity 234 generates and transmits one or more multicast messages 400 for entities reachable through switch 114 on ports other than its root port. For example, if port number seven at switch 114 were coupled to another access switch, entity 234 would transmit multicast messages 400 carrying the source address of entities directly coupled to this additional access switch as well. Thus, at least one multicast message 400 is generated and transmitted for each entity directly coupled to or downstream of access switch 114 (relative to the root). As set forth above, upon receipt of these multicast messages 400, the other devices within network 100 update their corresponding filtering databases with the new destination ports, as necessary. Ex. 1005, col. 13, l. 50–col. 14, l. 3 (emphasis added). Gai thus expressly contemplates the addition of “another access switch” coupled to port 7 of switch 114. Switch 117 in the modified Figure 1 is such a switch. See PO Resp. 30 (Patent Owner arguing that “a [person of ordinary skill in the art] would understand that switch 117 is an access switch”); Ex. 1018, 84:14–85:9 (Dr. Olivier agreeing that switch 117 is an “access switch”). And because an “access switch” has “ports that connect to LANs and/or to other network endpoints, such as user computer systems,” and the above disclosure mentions “entities directly coupled to th[e] additional access switch,” switch 117 would be directly connected to a device like server 112e as well. See Ex. 1001, col. 1, ll. 31–33; Ex. 1005, col. 13, ll. 59–63; supra Section II.B. We credit Dr. Houh’s testimony that Gai in its written description expressly discloses the particular “variation of the topology” of Figure 1 that Petitioner asserts. See Ex. 1003 ¶ 165. Third, Patent Owner argues that Petitioner has not established that a person of ordinary skill in the art “would have had a reasonable expectation of success in modifying Gai to meet the claims.” PO Resp. 14–16 (citing Ex. 2001 ¶¶ 47–49). Patent Owner’s arguments are primarily directed to Petitioner’s asserted modification for its “1A” theory. See id. To the extent Patent Owner’s arguments apply to claim 1 and “1B,” we disagree, as Gai expressly describes the asserted modification to Figure 1 (i.e., adding an access switch connected to port 7 of switch 114). Thus, we are persuaded that a person of ordinary skill in the art would have had a reasonable expectation of success in achieving the method of claim 1 based on Gai’s full disclosure.” slip op. at 33

Here, Szrek expressly teaches indirect communication as a possible implementation of its system and Petitioner’s combination—employing Llach’s third-party transaction processor as part of the indirect communication channel—offers the attractive benefit of allowing Szrek’s system to support different game providers, which would reduce some implementation costs even if it might increase other costs, e.g., by having to program certain components (e.g., the cash registers) differently.

    “Ex. 1001, 4:46–50. This passage indicates that the interconnect can be a network on a chip and the network on a chip can include wires and buses. That does not necessarily mean that the interconnect can be just wires or buses; rather, it discloses that the interconnect can include wires and buses. In context, the disclosure regarding wires and buses does not support construing the corresponding structure broadly enough to encompass just wires and buses. The networks that constitute the corresponding structure, however, could include networks with wires and buses. Therefore, we agree with Patent Owner that the corresponding structure for the interconnect means should not include a mere bus, switch, and point-to-point wire and instead find that the corresponding structure under 35 U.S.C. § 112 ¶ 6 is a network, which the ’052 patent describes as a multi-hop interconnection between modules separated by one or more network nodes. See Ex. 1001, 2:33–37. Because this structure corresponds to the construction of “interconnect means” proposed by Patent Owner and adopted by the district courts in the TI and Qualcomm litigations (see supra Section III.C.3.b), and we do not rely in our analysis below on a recourse to “equivalents thereto” as permitted by § 112 ¶ 6, we note that our ultimate conclusions on the unpatentability of the challenged claims would be the same if § 112 ¶ 6 did not apply. iii. Conclusion For the reasons stated above, we construe “interconnect means” to cover the structure described in the Specification corresponding to the specified functions of “coupling said plurality of processing modules (M, S)” in the context of claim 6 and “coupling said plurality of processing modules (M, S)” and “enabling a connection-based communication having a set of connection properties” in the context of claims 1 and 7—i.e., a “multi-hop interconnection between modules separated by one or more network nodes”—and equivalents thereof.” slip op. at 28

    “II. ANALYSIS A. Level of Ordinary Skill in the Art Relying on the Schubert Declaration, Petitioner proposes that a person of ordinary skill in the art “would have had a bachelor’s degree in electrical engineering, physics, materials science, or a related discipline, and 6 years of 1 The Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112–29, 125 Stat. 284 (Sept. 16, 2011), includes amendments to Section 103 that became effective on March 16, 2013. Because the challenged claims issued from an application filed before March 16, 2013, we apply pre-AIA law. See Pet. 2; Ex. 1001, codes (22), (30). 2 US 2009/0021955 A1, published January 22, 2009 (Ex. 1004, codes (10), (43)) (“Kuang”).

    “The “context” is typically evaluated by reviewing the intrinsic record. See e.g., Regeneron, 130 F.4th at 1380–84. Here, as discussed above, the ’546 patent has multiple disclosures where a curtain lamp has a single light-emitting diode in one light-emitting diode string. See Ex. 1001, 1:33–36, 6:15–20, 6:27–40, 8:25–45. In particular, the ’546 patent similarly discloses a first curtain lamp with one LED in one light string, as well as a second curtain lamp, which provides further support for Petitioner’s proposed interpretation. Id. at 8:25–45. Although Patent Owner argues that Figures 7 and 8 disclose multiple LEDs and light strings in curtain lamps, other embodiments and claims explicitly indicate single components in a “curtain lamp.” “[T]here is a strong presumption against a claim construction that excludes a disclosed embodiment.” See In re Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1324 (Fed. Cir. 2011). Given that certain embodiments and claim 8 disclose a curtain lamp with one light string with one LED, we decline to interpret the claim to prohibit Petitioner’s interpretation. Additionally, we do not find that Petitioner’s claim interpretation renders the claim terms nonsensical or illogical. See Becton, 616 F.3d at 1255. Patent Owner asserts otherwise, arguing that Petitioner’s interpretation is based upon a “nonsensical” or “absurd[]” argument, there is no reason to have both a master and slave control unit to operate a single LED, and the interpretation renders most of the components superfluous. See PO Sur-reply 12; PO Resp. Supp. Br. 5. As discussed above, however, although the ’546 patent does not appear to provide any explanation for why there are master and slave control units to operate a single LED, the patent nevertheless discloses that in embodiments. This situation is also distinguishable from Becton, where “unequivocal language” of the claim recited “spring means ‘connected to’ the hinged arm,” such that interpreting the spring means and the hinged arm as the same structure would have rendered the claim nonsensical. Becton, 616 F.3d at 1254–55. Becton further found that interpreting the spring means and hinged arm as the same structure would be inconsistent with descriptions of the elements in the specification. Id. Here, in contrast, the ’546 patent Specification is replete with disclosures of a curtain lamp having one light string with one LED, and claim 8 is directed to the same. Accordingly, we adopt Petitioner’s interpretation of these claim elements.” slip op. at 36

  • Strike new argumentNew argument consideredDecided for petitioner

    “Although Patent Owner argues that Petitioner’s arguments in the Reply on “light strings” and “curtain lamp” as they relate to a single LED are improper, we do not agree. As Patent Owner acknowledges, the Petition and Dr. Schubert’s original declaration stated that a “curtain lamp” is “commonly understood to be one or more light strings.” See PO Sur-reply 12; see also Pet. 8; Ex. 1003 ¶ 37. Patent Owner did not contest Petitioner’s interpretation in its Response. See PO Resp. 15. Patent Owner did, however, argue that Kuang did not teach or suggest “light strings” in any form and therefore did not teach a “curtain lamp” under Petitioner’s definition of the same. PO Resp. 15–17. A petitioner reply may respond to arguments raised in a patent owner’s response under 35 U.S.C. § 42.23(b), and here Petitioner’s argument that a light string may have a single LED is properly presented in its Reply in response to Patent Owner’s arguments. Further, Patent Owner was not only aware that Petitioner had taken the position that a “curtain lamp” could be a single “light string,” but Patent Owner also did not dispute Petitioner’s interpretation.8 Our view, therefore, is that Petitioner’s argument that a curtain lamp may be a single LED is proper because it is corollary to Petitioner’s reply arguments on light strings. That is, Petitioner’s assertion follows from the reply arguments on light strings and the unopposed interpretation of curtain lamp as a single light string. Additionally, to the extent there could be any prejudice to Patent Owner by these light string and curtain lamp arguments, Patent Owner has had opportunities to address them by supplemental briefing.” slip op. at 32

Further, we agree with Petitioner that “[t]he ability to handle multiple requests would expand the capabilities and flexibilities of the chatbot-RPA bot” as well as “improv[e] costs, time, and capabilities.” Id. at 19–20 (citing Ex. 1003 ¶¶ 95, 96, 99). Both Symons and Williams support this argument. Ex. 1011, 2 (stating that RPA “support[s] repetitive, labor-intensive and transactional business processes,” that “software robots [are] an attractive way to drive operational cost reduction,” and that “[a]utomation through RPA can offer a return on investment (ROI) often ranging between 30 and 50 percent”); id. at 5 (stating that “[d]eployment of these cognitive tools promises new levels of productivity and innovation–freeing human workers to focus on higher-value activities and bringing industrial-level quality, consistency and auditability to business processes”); Ex. 1004, 2 (stating that “combining [RPA bots and chatbots] to automate processes can tremendously boost productivity in multiple organizations” and that “[RPA bots] reduce[] costs and human efforts”). Patent Owner’s argument that “[n]either Symons nor Williams suggest using a single chatbot-RPA to handle multiple requests at once in the same conversation thread” (PO Resp. 38) is not commensurate with the claim language, which does not require a single automation process (e.g., chatbot-RPA) to handle multiple inputs (e.g., multiple requests in the same conversation thread). See Reply 9–10. Regardless, however, we are not persuaded that Williams does not suggest using a single chatbot-RPA to handle multiple requests, as argued by Patent Owner. Sur-reply 9; see Ex. 1011, 2 (stating, for example, that “[t]he most common processes enabled by RPA today include back-office administrative processes and workflow within IT, finance, procurement, and human resources functions” and that “RPA enlists software robots to perform complex, nested routines that cut across multiple applications and interact with these systems”); id. at 3 (“Through several scripted questions, the virtual agent can surmise that the supplier is asking for status on their payment and, thus, trigger an RPA robot to access the appropriate enterprise resource planning (ERP) backend system, validate the caller’s details, retrieve necessary information, and provide status back in real-time to the supplier.”).” slip op. at 35
