Arista Networks challenges Orckit Corporation's patent (10652111) in an IPR, asserting that the claimed Deep Packet Inspection functionality within a Software Defined Networking controller is obvious.
Meta Platforms, Inc. v.Sitnet, LLC
The PTAB found that Claims 1-9 and 20 are unpatentable over prior art references (Amidon, Wong, Gogic) based on obviousness. Additionally, the Board granted an Adverse Judgment to cancel claims 10-19.
Reolink Innovation Inc. et al. v.Throughtek Co., Ltd.
The PTAB issued a Final Written Decision finding the challenged claims unpatentable over various combinations of prior art. The Board specifically found Claim 1 obvious over Lorex Guide and Kim, while also addressing issues of written description and statutory eligibility.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
The PTAB issued a Final Written Decision finding that claims 1 and 6 of the patent were unpatentable over prior art references Wainner and Bocci. The Board agreed with the Petitioner's argument that combining these references rendered the claimed method obvious, particularly regarding shared link functionality in pseudo-wires.
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.
Juniper Networks, Inc. v.Portsmouth Network Corporation
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.
Meta Platforms, Inc. v.Sitnet, LLC
Meta Platforms successfully secured institution in its IPR challenge against Sitnet, LLC's '454 patent. The Board found sufficient support for obviousness over Amidon and Wong/Gogic, advancing the dispute to trial.
Reolink Innovation Inc. et al. v.Throughtek Co., Ltd.
The PTAB institution decision found sufficient evidence of obviousness under 35 U.S.C. § 103 for multiple claims related to peer-to-peer connection establishment. The Petitioner successfully demonstrated that combining prior art references, such as the Lorex Guide and Kim, taught all limitations of several claimed features. This outcome significantly advances the challenge against the patent's validity in this technology area.
Cisco Systems, Inc. v.Portsmouth Network Corporation
Cisco Systems successfully petitioned to challenge Portsmouth Network Corporation's patent (8014394) in an IPR proceeding, leading the PTAB to institute the case. The Board found a reasonable likelihood of prevailing for several claims based on obviousness over prior art references Weyman and Li.
Cisco Systems Inc. v.Portsmouth Network Corporation
The PTAB decided to institute the IPR, finding that Petitioner demonstrated a reasonable likelihood of prevailing on at least one claim. The Board agreed with the petitioner's argument that prior art reference Gai teaches or suggests key limitations related to dummy traffic and spanning tree protocol operation in network switches.
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 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.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 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.Portsmouth Network Corporation
The PTAB found the patent claims unpatentable under 35 U.S.C. § 103(a) based on various combinations of prior art references.

Arista Networks, Inc. v.Orckit Corporation
Arista Networks successfully secured the institution of Inter Partes Review against Orckit Corporation's patent (10652111). The Board found a reasonable likelihood that Arista could prove obviousness based on prior art related to Software Defined Networking and Deep Packet Inspection.
Microsoft Corporation v.Edge Networking Systems, LLC
