Cisco’s request for rehearing of the Director Review decision in IPR2025-00188 was denied, maintaining the denial of institution of the inter partes review against patent 8,982,691.
Cisco Systems, Inc. v.WSOU Investments LLC d/b/a Brazos Licensing and Development
Cisco has filed an IPR petition seeking to invalidate claims 1‑10 of WSOU’s ’691 MPLS patent, asserting obviousness over multiple prior‑art references and arguing against discretionary denial.
Juniper Networks, Inc v.Monarch Networking Solutions LLC
Juniper Networks challenges the validity of Monarch Networking Solutions' '845 patent, asserting that claims related to IPv6/IPv4 transition and NAT are obvious under 35 U.S.C. § 103. The petitioner relies on combinations of prior art references (Li, Li-2, Paunikar, Wu) to demonstrate the lack of nonobviousness in networking technology.
DISH Network L.L.C. et al. v.Entropic Communications LLC
DISH Network L.L.C.'s attempt to invalidate 40 claims of Entropic Communications' patent (8363681) was denied by the PTAB. The Board found insufficient evidence that the claimed clock synchronization methods were obvious over prior art, including IEEE802.3ah and Shvodian.
CISCO SYSTEMS, INC. et al. v.InfoExpress Inc.
CISCO SYSTEMS, INC. filed an IPR petition challenging claims of InfoExpress Inc.'s patent (8,347,350), arguing they are obvious under 35 U.S.C. § 103. The challenge relies on combining prior art references Krantz and Herrmann to demonstrate predictable network access control features.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
Monarch’s response to Juniper’s IPR argues that the challenged claims of U.S. Patent 8,130,775 are not obvious, emphasizing that prior‑art references do not disclose a shared link between two pseudo‑wires.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
Monarch Networking’s sur‑reply defends the validity of its MPLS‑pseudowire patent against Juniper’s IPR petition, arguing the prior art does not disclose the claimed shared‑link architecture.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
Monarch’s preliminary response urges the PTAB to deny Juniper’s IPR petition, arguing the cited references do not teach a shared link between two pseudo‑wires and that the petition repeats arguments already considered by the USPTO.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
Juniper Networks successfully petitioned to institute IPR against Monarch Networking Solutions LLC regarding packet switching claims (Claims 1 and 6). The Board found sufficient evidence of obviousness over combinations of prior art references, including Wainner/Bocci and Kamite/Bocci.
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.
Reolink Innovation Inc. et al. v.THROUGH TEK TECHNOLOGY (SHENZHEN) CO., LTD. et al.
Petitioner Reolink Innovation Inc. challenged U.S. Patent No. 10,602,448 covering remote wakeup systems in a PTAB petition. The challenge asserts that the patent is unpatentable under 35 U.S.C. §102 and §103 based on various combinations of prior art references (Zhang, Zill, Liu).

Cisco Systems filed an Initial Petition for Inter Partes Review challenging Video Solutions Pte. Ltd.'s patent (8446823) on grounds of obviousness under 35 U.S.C. §103. The petitioner argues that the claimed methods for managing traffic peaks and delay sensitivity in videoconferencing are predictable combinations of known prior art techniques. This challenge targets core data flow control mechanisms used in multi-party packet networks.
Juniper Networks, Inc. v.Orckit Corporation
Juniper Networks challenges Orckit Corporation's patent via IPR, arguing that the claimed Deep Packet Inspection (DPI) and Software Defined Networking (SDN) methods are obvious. The Petitioner asserts that combining prior art teachings from Lefebvre, Chua, and Rash renders the claims unpatentable under 35 U.S.C. § 103.
Juniper Networks, Inc. v.Portsmouth Network Corporation
Juniper Networks filed a Petition to challenge U.S. Patent No. 8,014,394 held by Portsmouth Network Corporation. The petition asserts that several claims related to multicast routing and switch fabric are obvious over prior art references Blease, Weyman, Hu, Deng, and Rao under 35 U.S.C. § 103. This proceeding addresses the core validity of networking technology patents.
Juniper Networks, Inc. v.Portsmouth Network Corporation
Juniper Networks has filed an Inter Partes Review (IPR) challenging U.S. Patent No. 8,014,394 held by Portsmouth Network Corporation. The petitioner asserts that the patent claims related to multicast routing and stream management are obvious over existing prior art references. This challenge targets core network fabric technology.
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.
