Cisco Systems, Inc. v.Portsmouth Network Corporation
Cisco Systems successfully argued that multiple claims of Portsmouth Network Corporation's patent were unpatentable over prior art references Dziong and Sathyanath, specifically regarding network routing and bandwidth allocation. The PTAB found a reasonable likelihood of prevailing on several key claims, leading to the institution of the IPR.
Cisco Systems, Inc. v.Portsmouth Network Corporation
The PTAB rejected Cisco's IPR challenge against the '088 patent, finding no grounds for obviousness over prior art references Dziong and Sathyanath. The Board construed the key term "other connections" narrowly to mean established connections with allocated bandwidth, favoring the Patent Owner's interpretation.

Charter Communications’ IPR petition against Iarnach Technologies’ 9,287,982 patent was deemed insufficient. The Patent Owner’s response argues the petitioner ignored the limiting preamble and failed to provide particularized obviousness arguments.
Charter Communications, Inc. v.Iarnach Technologies Limited
Charter Communications' IPR petition against Iarnach Technologies' DOCSIS auto‑configuration patent is challenged by the patent owner, who argues the petitioner's reply adds new, undisclosed arguments, violating the IPR rules.

Charter Communications, Inc. v.Iarnach Technologies Limited
Charter Communications has filed an IPR petition seeking cancellation of all 13 claims of U.S. Patent 8,942,378, which covers multicast encryption in passive optical networks.

Charter Communications, Inc. v.Iarnach Technologies Limited
The PTAB instituted the IPR for Charter Communications against Iarnach Technologies, finding sufficient evidence that claims of Patent No. 9287982 are obvious over various prior art references (Bernstein, Tsuge, MEF 6.1). The Board addressed numerous claim construction issues, confirming some preambles were limiting while others were not.
Charter Communications, Inc. v.Iarnach Technologies Limited
Charter Communications, Inc. failed to invalidate 13 claims covering Passive Optical Networks (PON) and multicast encryption technologies before the PTAB. The Board denied institution based on insufficient evidence showing obviousness over prior art including RFCs and Murakami.
Juniper Networks, Inc v.Monarch Networking Solutions LLC

Google LLC v.--
Google LLC has initiated a Petition challenging U.S. Patent No. 8,825,787 held by Songbird Tech, LLC. The petitioner argues that the patent claims covering voice messaging and web communication systems are unpatentable under both 35 U.S.C. §§ 102 and 103. This challenge targets fundamental components like audio encoding/decoding and browser-resident applications.
Cisco Systems, Inc. v.Croga Innovations Ltd.
Cisco has filed an IPR petition seeking to invalidate claims 1 and 2 of Croga Innovations’ VoIP codec‑switching patent, arguing obviousness over multiple prior‑art references and asserting that discretionary denial is unwarranted.
Cisco Systems, Inc. v.Croga Innovations Ltd.

Google LLC et al. v.Mullen Industries LLC
The Director denied institution of IPR for Mullen Industries against Google LLC et al., vacating the prior decision. The denial was based on a holistic Fintiv analysis where procedural factors outweighed the merits.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
Juniper Networks challenged U.S. Patent 8,130,775 in an IPR, arguing that claims 1 and 6 were obvious over combinations of Wainner, Bocci, and Kamite. The Board found the merits strong and ruled to institute the proceeding, noting prior art was not substantively analyzed by the Examiner.
CommScope Technologies LLC et al. v.Belden Canada ULC et al.

The Board found Petitioner’s arguments persuasive regarding the technical scope of the modular fiber optic cassette system.
Samsung Electronics Co., Ltd. et al. v.KP INNOVATIONS 2, LLC
Samsung Electronics' IPR challenge against KP Innovations was denied institution by the PTAB, despite arguments of anticipation and obviousness. The Board cited concerns over inefficient use of time and resources to decline institution, though a dissent argued for prevailing likelihood.
Google LLC et al. v.Mullen Industries LLC
Google LLC et al. successfully petitioned to institute IPR against Mullen Industries LLC's patent covering location services and tracking. The Board found sufficient evidence of non-obviousness, despite parallel district court litigation, leading to the institution of all 30 claims.
Cisco Systems, Inc. v.Video Solutions Pte. Ltd.
Cisco Systems lost its IPR challenge against Video Solutions Pte. Ltd., with the PTAB rejecting claims of obviousness over Larson and Cai. The Board found that Petitioner failed to provide sufficient technical explanation for how a person skilled in the art would combine prior art references.
Roku, Inc. v.VideoLabs, Inc.
Roku successfully petitioned for the institution of IPR against VideoLabs regarding claims related to Conditional Access and Digital Rights Management.

Comcast Cable Communications, LLC et al. v.Entropic Communications, LLC
Comcast defends its three parallel IPR petitions against Entropic Communications, asserting they comply with PTAB guidance and are essential for addressing multiple invalidity grounds. The response urges the Director to reject the Patent Owner’s request for review.
Cisco Systems, Inc. v.Scale Video Coding LLC
The PTAB denied Cisco Systems' IPR petition against Scale Video Coding LLC, finding the asserted claims were not reasonably likely to be unpatentable over prior art references. The decision focused on technical limitations regarding bandwidth identification in video routers.
Juniper Networks, Inc. v.Portsmouth Network Corporation
The PTAB instituted the IPR petition filed by Juniper Networks against Portsmouth Network Corporation, finding a reasonable likelihood of prevailing on multiple grounds. The Board specifically accepted arguments that challenged claims 1, 2, 4, 6, 7, and others based on obviousness over Blease in view of Weyman and Hu.
Nokia of America Corporation et al. v.Iarnach Technologies Limited
Iarnach Technologies seeks denial of an IPR filed by Nokia and AT&T over U.S. Patent 9,806,892 covering direct power‑state transitions in passive optical networks. The owner argues the cited references do not disclose such transitions and invokes Fintiv discretionary denial factors due to parallel district‑court cases.
Cisco Systems, Inc. v.Portsmouth Network Corporation
Cisco Systems' attempt to overturn the denial of IPR institution against Portsmouth Network Corporation was rejected by the Delegated Review Panel. The DRP upheld the Board's implicit claim construction, finding that the claims covered all network nodes, not just downstream ones.
Aylo Freesites Ltd et al. v.DISH Technologies L.L.C. et al.
The Director vacated the Final Written Decision and dismissed the IPR petition filed by Aylo Freesites Ltd against DISH Technologies L.L.C., finding that the petition was time-barred after correcting its list of Real Parties in Interest.
Cambridge Mobile Telematics, Inc. v.Sfara, Inc.
The PTAB denied institution of IPR for Cambridge Mobile Telematics against Sfara, citing Petitioner's failure to provide a proper claim construction under 37 C.F.R. § 42.104(b)(3). Additionally, the Board found that key 'component' terms functioned as means-plus-function limitations lacking cognizable structure in the patent specification.
