Cisco Systems Inc. v.Portsmouth Network Corporation

· IPR2024-00505

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.

patent final

Cisco Systems, Inc. v.Portsmouth Network Corporation

· IPR2024-00506

· IPR2024-00913

The PTAB issued a Final Written Decision finding that ten of the fifteen challenged claims were unpatentable under 35 U.S.C. § 103 based on various combinations of prior art references (Blease, Weyman, Hu, Deng). The Board found sufficient motivation to combine Blease and Weyman for distributed architecture features, while also finding that combining Blease/Weyman with Hu was plausible for bandwidth efficiency improvements.

patent Final Written Decision

Adobe Inc. v.Jaffe, Jonathan

· IPR2024-01352
