“First, the claims use present-tense language, “one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection.”3 Ex. 1001, claim 1 (emphasis added). The exclusive use of the present tense have indicates “other connections” must have current possession of the bandwidth. For these other connections to share bandwidth with a newly established connection, they must already exist and have bandwidth ready for immediate use, rather than merely holding a dormant “reservation” pending a network failure. See PO Supp. Br. 1. The Federal Circuit addressed a similar situation where the Court found the present-tense limitation “is connected to the computer network” means a device was required to be connected at the” slip op. at 15

“combination, do not teach or suggest limitations 1.2 and 1.3 requiring: providing a sharing definition specifying one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection, such that a total bandwidth allocated jointly to the new connection and to the other connections in any given segment is equal to a maximum of the requested bandwidth and of the bandwidths of the other connections in the given segment Ex. 1001, limitations 1.2, 1.3 (emphasis added); see PO Resp. 17–22; Sur-reply 4–5, 12–14. As discussed above in Section II.C.2, we interpret “other connections” to mean “existing connections in the network that already have bandwidth allocated to them.” Because the information shared in Dziong and Sathyanath, described below, relates to reserved protection paths, rather than existing connections that have bandwidth that can currently transmit network traffic, the references do not teach or suggest the “other connections” part of the sharing definition in limitations 1.2 and 1.3. Dziong describes advertising, across the network, the amount of bandwidth reserved for recovery on each link that would be activated when a protected link fails. See, e.g., Ex. 1005 ¶ 60; Pet. 36. Once activated, network traffic from a “primary path” failure is rerouted to these recovery paths. See Ex. 1005 ¶¶ 7–9, 70, 83. Petitioner points to this advertising of the reserved bandwidth information as teaching the claimed “sharing definition.” Pet. 33–36 (arguing that the “protection paths [in Dziong] have bandwidth reservations” and “share an overall protection bandwidth reservation”); Reply 21–23. However, since the advertised information only contains information about the recovery paths “that would be activated” upon a primary path failure, such paths are not existing connections that already have bandwidth allocated to them, and therefore do not teach the claimed “other connections” that are part of the sharing definition.

To the contrary, the only specific discussion of identifying bandwidth in Shao-028 says that it takes place upstream of the video router, rather than downstream in the link in question.

“Accordingly, on this record, Petitioner has not demonstrated a reasonable likelihood that Shao-028 teaches or suggests “identify[ing] bandwidth-limited conditions of an internet protocol network between the video router and a [plurality/set] of video receivers.” As such, Petitioner has not demonstrated a reasonable likelihood that Shao-028 would have rendered independent claims 1, 6 or 11 obvious. As to dependent claims 2, 3, 5, 7, 8, 10, 12, 13 and 15, Petitioner makes no further allegations that would remedy the deficiency discussed above in regards to the independent claims. See Pet. 51–56. As such, Petitioner has not shown a reasonable likelihood that any of claims 1–3, 5–8, 10–13 and 15 would have been obvious over the asserted art in Ground 1. Petitioner in Ground 2 asserts alternative arguments for why independent claims 1, 6 and 11 would have been obvious in view of Shao- 023 and an additional reference Shao-423. Pet. 56–70. Because Ground 2 relies on the same argument for why Shao-023 teaches or suggests the limitation “identify[ing] bandwidth-limited conditions of an internet protocol network between the video router and a [plurality/set] of video receivers,” see Pet. 56, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on Ground 2 for the same reasons discussed above for Ground 1.” slip op. at 19

“We do not agree that Zalewski is substantively identical to Willgert.

Ex. 2001, 7:63–8:3. Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirement of a “communication device determining the mobile communication device is in an operational space” was not met.

“not agree, based on the current record, that the claims should be construed to encompass a device that has independent RFID transponder components that are separate from and independent of the components that provide voice call capability. During prosecution of related applications, in distinguishing Zalewski, Applicant disavowed such a broad interpretation. For example, Applicant asserted: The term “transceiver” . . . is well understood by those of ordinary skill in the art. One of ordinary skill in the art would not reasonably interpret a "transceiver" so broadly as to incorporate an entire mobile device's circuitry, and in particular to be read on by two separate transmitters . . . . Ex. 1008, 40. Also: [A] person having ordinary skill in the art would have understood “a transceiver of a mobile communication device” to be a transmitter and receiver combined in a single package/housing/unit and sharing at least some common circuitry for both transmission and reception located within a mobile communication device. . . . . A person having ordinary skill in the art would understand Applicants’ disclosure as describing a single transceiver that can be switched from a first state in which it transmits voice call signals to a second state in which it transmits RFID signals. Id. at 92, 94.

Pet. 53–54 (citing Ex. 1003 ¶¶ 129–130). At this stage of the proceeding, we find support for this position, including the fact that Willgert specifically teaches that the communications unit can be integrated into a mobile telephone. Ex. 1004 ¶ 32. Patent Owner challenges this argument based on the statement in Willgert that the communications unit can be “constructed so that the transponder will also function when the mobile telephone is switched-off.” Prelim.

“Willgert/Mooney combination does not teach or suggest the voice call signal requirements of the claims. As stated in the ’984 patent, the voice call signals relate to “the primary function of [the mobile communications device], i.e. to facilitate a user in communicating with another user of another communication device.” Ex. 1001, 3:47–49. The proffered combination of wirelessly connecting a Bluetooth headset to the Bluetooth receiver/transmitter of Willgert’s communications unit includes the fact that the Willgert communications unit is integrated into a mobile telephone. Ex. 1004 ¶¶ 30, 32. Thus, when the telephone is being used for its “primary purpose” of communicating with another user, the same voice call signal involved in that communication is also being transmitted from the telephone to the Bluetooth headset. We see no reason why the claimed “voice call signals” must be construed to exclude such signals. Patent Owner declined to address claim construction in its Preliminary Response, but is free to explore this issue post-institution. We also disagree, based on the current record, with Patent Owner’s assertion that Willgert’s RFID transponder 2 does not transmit “RFID transponder data” or “RFID transponder signals.” The very term itself — RFID transponder — as well as the explicit disclosures in Willgert, establish that the RFID transponder transmits RFID signals and data. Ex. 1004 ¶¶ 4, 14–19. Although, as Patent Owner points out, the ’984 patent discloses embodiments that “emulate” an RFID transponder, there is no reason to confine the scope of the claims to the disclosed embodiments and there is nothing in the ’984 specification or claims that disavows including Willgert’s RFID transponder within the scope of the claims. Also, Patent Owner’s reliance on the prosecution history regarding the Zalewski patent is misplaced. As Patent Owner has explained, Zalewski disclosed “‘an RFID transponder 110’ embedded in a removable cover for a phone or other device ‘such as an MP3 player.’” Prelim. Resp. 14 (citing Ex. 2001, 7:63–8:3). Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirements of a transceiver or transmitter switching between a voice call state and an RFID transponder state were not met. Ex. 1002, 18, 91, 134–135, 155; Ex. 1009, 530. Zalewski was not distinguished based on whether or not the RFID transponder was emulated.

Therefore, there are no serial petitions, as that term is used in General Plastic, filed in these IPRs. However, “our application of the General Plastic factors is not limited solely to instances when multiple petitions are filed by the same petitioner. Rather, when different petitioners challenge the same patent, we consider any relationship between those petitioners when weighing the General Plastic factors.” Valve Corp. v. Elec. Scripting Prods., Inc., IPR2019-00062, Paper 11 at 9 (PTAB Apr. 2, 2019) (precedential). Petitioner argues that “no significant relationship exists” between it and Cisco, as they were “accused of infringing the ’394 patent with different products in different court proceedings . . . and have not coordinated regarding the ’394 patent, the separately accused products, or the filing of petitions for IPR.” Pet. 70. Patent Owner provides no evidence of a significant relationship between Petitioner and Cisco, but nonetheless argues that factors 1–5 favor discretionary denial anyway, because Petitioner had knowledge of the Cisco petition, citing the Board’s decision in Ericsson Inc. v. Uniloc 2017, LLC, IPR2019-01550, Paper 8 at 11–12 (PTAB Mar. 17, 2020) (“Ericsson”), for the proposition that Petitioner’s use of the Cisco petition as a roadmap ties the interests of the petitioners together. Prelim. Resp. 26. We are not persuaded by this assertion. First, Ericsson is not a precedential or informative decision and is not binding on us or informative to our analysis. Moreover, in that case there were five prior petitions that covered all of the challenged claims, and the petitioner admitted crafting its petition based on its review of the prior petitions. Ericsson at 3, 11. Petitioner here has not made such a concession, and moreover, Patent Owner has not presented any evidence that Petitioner actually did use the petition in IPR2024-00506 as a roadmap. Under the circumstances, we find no evidence that Petitioner used the prior petition filed by Cisco as a roadmap, particularly when none of the timing associated with the prior petition was within its control. We find no significant relationship between Petitioner and Cisco. “[W]here, as here, the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” Videndum Prod.

See, e.g., Ex. 1005, code (57) (“The network device transmits multicast traffic to the subscriber devices.”); Ex. 1007, claim 17 (“A network device to allocate media streams . . . .”), 1:20–29 (disclosing that, if “insufficient bandwidth [is allocated] to video streams, the quality of service degrades”); see Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023) (“That [two prior art references] address the same problem and that [one of the references] was a known way to address that problem is precisely the reason that there’s a motivation to combine under KSR and our precedent.”). On this record, we are persuaded that applying Hu’s port aggregation teaching to Blease’s router would be the application of a known technique to improve the router to allow it to provide multicast streams that require higher bandwidth with predicable results. Pet. 28; see KSR, 550 U.S. at 415–21. As pointed out by Petitioner, these two concepts could be combined together in a straightforward manner and applied to streams that require high-capacity ports, a technique already applied elsewhere in Blease to other ports, so a POSITA would have had a reasonable expectation of success in doing so. Pet. 28–29; Ex. 1003 ¶¶ 93–94; see Elekta Ltd. v. Zap Surgical Sys., Inc., 81 F.4th 1368, 1377 (Fed. Cir. 2023) (“Evidence of reasonable expectation of success, just like evidence of a motivation to combine, ‘may flow from the prior art references themselves, the knowledge of one of ordinary skill in the art, or in some cases, from the nature of the problem to be solved.’”) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). On this record, we are unpersuaded by Patent Owner’s argument that Blease teaches away from using aggregated ports to form a high-capacity link because “Blease’s disclosure is clear that the focus of its multicast techniques is to reduce, not increase, the amount of multicast traffic flowing through network.” Prelim. Resp. 14. The discussion in Blease of minimizing the bandwidth does not relate to restricting the bandwidth required for a particular stream as Patent Owner seems to assert, but rather to eliminating duplicate transmissions of the same multicast stream to be delivered to multiple subscribers. See Ex. 1005, 2:39–42, 4:50–56 (“The multicast transmission techniques described herein may significantly reduce the amount of multicast traffic . . . . For example, regardless of the number of subscriber devices[] connected to the same network switch that request the same multicast stream, [the] network device[] only sends one copy of the multicast stream to the network switch.”). Therefore, aggregating ports to accommodate transmission of a single multicast stream that requires more bandwidth is a different concept that is unrelated to the discussion in Blease about minimizing bandwidth by increasing efficiency.” slip op. at 37

“same day, May 31, 2024, and the prior petition in IPR2024-00506 was filed by a different party previously sued for infringement of the ’394 patent in a different district court case. Therefore, there are no serial petitions, as that term is used in General Plastic, filed in these IPRs. However, “our application of the General Plastic factors is not limited solely to instances when multiple petitions are filed by the same petitioner. Rather, when different petitioners challenge the same patent, we consider any relationship between those petitioners when weighing the General Plastic factors.” Valve Corp. v. Elec. Scripting Prods., Inc., IPR2019-00062, Paper 11 at 9 (PTAB Apr. 2, 2019) (precedential). Petitioner argues that “no significant relationship exists” between it and Cisco, as they were “accused of infringing the ’394 patent with different products in different court proceedings . . . and have not coordinated regarding the ’394 patent, the separately accused products, or the filing of petitions for IPR.” Pet. 70. Patent Owner provides no evidence of a significant relationship between Petitioner and Cisco, but nonetheless argues that factors 1–5 favor discretionary denial anyway, because Petitioner had knowledge of the Cisco petition, citing the Board’s decision in Ericsson Inc. v. Uniloc 2017, LLC, IPR2019-01550, Paper 8 at 11–12 (PTAB Mar. 17, 2020) (“Ericsson”), for the proposition that Petitioner’s use of the Cisco petition as a roadmap ties the interests of the petitioners together. Prelim. Resp. 26. We are not persuaded by this assertion. First, Ericsson is not a precedential or informative decision and is not binding on us or informative to our analysis. Moreover, in that case there were five prior petitions that covered all of the challenged claims, and the petitioner admitted crafting its petition based on its review of the prior petitions. Ericsson at 3, 11. Petitioner here has not made such a concession, and moreover, Patent Owner has not presented any evidence that Petitioner actually did use the petition in IPR2024-00506 as a roadmap. Under the circumstances, we find no evidence that Petitioner used the prior petition filed by Cisco as a roadmap, particularly when none of the timing associated with the prior petition was within its control. We find no significant relationship between Petitioner and Cisco. “[W]here, as here, the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” Videndum Prod. Sols., Inc. v. Rotolight Ltd., IPR2023-01218, Paper 12 at 6 (Vidal Apr. 19, 2024).

“the parties’ arguments, we understand Mitchell to teach the propagation of failure information from the location of the failure to the network’s edge or endpoints and that this propagation excludes nodes between the detected failure and the network’s core. Therefore, the question before us is whether one of ordinary skill in the art would have learned of the recited propagation and receipt to and from “each node of the other nodes of the plurality of network nodes traversed by the first set of links”8 from Mitchell’s downstream propagation of failure information. We are not persuaded that Petitioner’s showing is sufficient. Petitioner relies upon a circumstance where the failure occurs far upstream and uses that case to assert that Mitchell teaches the recited propagation and receipt. Claims 1 and 16, however, respectively recite the propagation to “each node” and “all nodes.” Mitchell, in contrast, does not teach propagation to each node, but rather it teaches continuing down the path to message only the remaining nodes in the path between the failure and the endpoints. It specifically and explicitly sets out to maintain connectivity with all nodes upstream of the failure. This is materially different from the claims of the ’637 patent, and Petitioner has not provided a sufficient explanation to establish that one of ordinary skill in the art would have found it obvious to extend Mitchell’s downstream-only propagation to instead” slip op. at 19

“and 16. See Prelim. Resp. 7–10. For example, claim 1 additionally recites, in relevant part, “deactivating a physical layer of the first set of links connected thereto, thereby causing a loss of connectivity in the first set of links.” Ex. 1001, 11:37–39 (limitation [1h]). Claim 16 similarly recites, in relevant part, “to deactivate the physical layer resources of each node to links in the first set of links connected to that node upon receiving the second message, to cause a loss of connectivity in the first set of links.” Id. at 12:54–58 (limitation [16g]). Thus, claims 1 and 16 both require deactivating the physical layer of nodes in order to cause a loss of connectivity in the first set of links. Petitioner asserts that Mitchell teaches that “the physical layer of the links connected downstream of these network elements are deactivated, which causes a loss of connectivity in the ‘group of links.’” Pet. 26 (emphasis omitted); see also id. at 36 (making same argument for claim 16). We are not persuaded that downstream deactivation teaches the deactivation of “each node” nor does it teach the “loss of connectivity in the first set of links.” This is true because Mitchell teaches the preservation of connectivity in upstream links. Petitioner does not argue that one of ordinary skill would have understood Mitchell to teach deactivation of the set of links, but rather Petitioner argues that there could be a circumstance where Mitchell may be unable to preserve connectivity because the failure happened at the most upstream location. This is not sufficient to teach a system that deactivates all nodes in the set of links in order to cause a loss of connectivity in the set of links because Mitchell sets out to maintain some degree of connectivity. We agree with Patent Owner that the disclosures of Mitchell would not have taught one of ordinary skill in the art the recited propagation and receipt of failure information to and by each of the nodes in the network nor would it have taught the recited deactivation to cause a loss of connectivity in the set of links. As such, Petitioner has not met its burden to demonstrate that Mitchell would have rendered independent claims 1 or 16 obvious. As to dependent claims 2–15 and 17–25, Petitioner makes no further allegations that would remedy the deficiency discussed above in regards to the independent claims.
