Juniper Networks, Inc. v.Portsmouth Network Corporation
The PTAB issued a Final Written Decision finding several claims of the '986 patent unpatentable under 35 U.S.C. § 103(a). The Board concluded that the combination of prior art references, including Gai and an IEEE publication, taught the full scope of the claimed network failure recovery method.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
Cisco Systems successfully petitioned to challenge Umbra Technologies' patent (10630505) regarding Global Virtual Network optimization claims. The PTAB institution decision found reasonable likelihood of success based on obviousness over prior art combinations, specifically citing Hankins and Munger for several key claims.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
CISCO SYSTEMS successfully convinced the PTAB to institute trial on claims 15-20 of UMBRA TECHNOLOGIES' patent. The Board found reasonable likelihood of unpatentability based on obviousness over Hankins and Kommula, despite Patent Owner disputes regarding key technical terms.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
The PTAB found all 20 challenged claims unpatentable under 35 U.S.C. § 103 (obviousness). The Board adopted the Petitioner's analysis, concluding that the claimed technology was obvious over Hankins alone or in combination with Munger and Treuhaft.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
The PTAB issued a Final Written Decision finding that the Petitioner failed to prove unpatentability for claims 15-20 of the '595 patent. Claims 1-14 were mooted by disclaimer, resulting in no challenged claims being found unpatentable.
Cisco Systems Inc. v.Portsmouth Network Corporation
The PTAB found that a large group of claims (15) were unpatentable over the prior art reference Gai under 35 U.S.C. § 103(a). The Board relied on Petitioner's '1B' theory, which successfully demonstrated obviousness by showing Gai disclosed all limitations of the claimed network topology and dummy traffic function. Claims 11, 12, 23, and 24 survived the challenge.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
The PTAB denied Cisco's IPR petition against Umbra Technologies regarding network security claims (1-26). The Board found that the petitioner failed to demonstrate a reasonable likelihood of prevailing on obviousness over the combined prior art teachings.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
CISCO SYSTEMS, INC. successfully challenged seven claims of UMBRA TECHNOLOGIES LTD.'s patent under 35 U.S.C. § 103 (obviousness). The Board preliminarily found that the claimed invention was obvious over the prior art reference Agarwala and general knowledge of a Person Having Ordinary Skill in the Art (POSITA).
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
The Board issued a Final Written Decision finding all seven challenged claims unpatentable based on obviousness over the prior art reference Agarwala. The decision adopted Petitioner's construction that 'data beacons' was merely an intended use, and found that Agarwala disclosed every structural limitation of the claims through a combination of disclosures.
Cisco Systems, Inc. v.Portsmouth Network Corporation
The PTAB issued a Final Written Decision finding that claims 1-18 of the patent were unpatentable on grounds of obviousness over Kovvali and Kalman. The Board rejected the Petitioner's arguments, agreeing with the Patent Owner that there was no valid motivation to combine the references for resource allocation in ring topology data flow.
