Institution was denied because Petitioner did not show a reasonable likelihood that claims 1–3, 5–8, 10–13, or 15 would have been obvious over either asserted ground.

“We are persuaded by Patent Owner’s arguments that Petitioner has not shown a reasonable likelihood that any of the three cited aspects of Shao- 028 teach or suggest that bandwidth-limited conditions are identified on the link between the video router and the client devices as required by the claims. 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. See Ex. 1005, 13:39–40. Moreover, the control requests from the client devices do not convey bandwidth conditions at all. We address each of the three arguments from Petitioner on this limitation below.” slip op. at 12

“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

The Board denied institution on claims 1–25 because Mitchell did not teach or render obvious the required failure propagation to each node and deactivation causing loss of connectivity.

“Under 35 U.S.C. § 314(a), an inter partes review may not be instituted unless the information presented in the petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons stated below, we determine that Petitioner has not established a reasonable likelihood that it would prevail with respect to at least one claim. We, therefore, deny Petitioner’s request to institute inter partes review.” slip op. at 2

“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. As such, Petitioner has not met its burden to show that any of claims 1–25 would have been obvious over the asserted art.” slip op. at 20
