Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
Western Digital Technologies, Inc. failed its IPR challenge against a patent owned by Godo Kaisha IP Bridge 1 regarding Magnetic Tunnel Junctions (MTJ). The PTAB denied the petition on obviousness grounds (103), finding that the petitioner could not establish a reasonable likelihood of prevailing.
Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
The PTAB denied institution of an IPR petition filed by Western Digital Technologies against Godo Kaisha IP Bridge 1 because the patent owner had statutorily disclaimed all challenged claims.
Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
Western Digital Technologies successfully secured institution of its IPR against Godo Kaisha IP Bridge 1 regarding MTJ technology claims. The Board found sufficient evidence to support obviousness under 35 U.S.C. § 103 over combinations of prior art, including Bowen and Sunai.
Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
The PTAB found claims 1 and 2 unpatentable over the combination of Bowen and Parkin's prior art references. The Board concluded that combining these references taught all elements of the challenged claims, including a rationale for using amorphous, annealed CoFeB electrodes to achieve high TMR. Claims 3 and 4 were not found unpatentable.
Adobe Inc. v.Jaffe, Jonathan
The PTAB issued a Final Written Decision rejecting all claims of the '828 Patent. The Board adopted the Patent Owner's narrow claim construction, specifically requiring monitoring of the physical coupling between the sensor and memory. Petitioner failed to demonstrate that any combination of prior art references renders the claims obvious under 35 U.S.C. § 103.
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.
Juniper Networks, Inc. v.Portsmouth Network Corporation
Juniper Networks successfully navigated the PTAB's institution standards, leading to trial on numerous claims of Portsmouth Network Corporation's patent. The Board found a reasonable likelihood of prevailing based on obviousness grounds over Blease in view of Weyman and Hu.
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.
Rode Microphones, LLC et al. v.Zaxcom, Inc.
The PTAB Institute Decision granted trial for Rode Microphones and Freedman Electronics against Zaxcom regarding wireless audio recording systems. The Board found that the Petitioner successfully demonstrated a reasonable likelihood of prevailing on at least one claim, despite procedural hurdles related to parallel district court litigation.
Rode Microphones, LLC et al. v.Zaxcom, Inc.
The PTAB granted institution of the IPR against Zaxcom's '902 patent for wireless multi-track audio systems, finding a reasonable likelihood of prevailing on obviousness grounds. The Board conducted preliminary claim constructions for key terms like 'wearable' and 'master timecode.'
Rode Microphones, LLC et al. v.Zaxcom, Inc.
Rode Microphones and Freedman Electronics successfully petitioned for IPR institution against Zaxcom's audio recording patents, demonstrating a reasonable likelihood of prevailing. The Board found that the combination of Strub and Woo renders the claimed synchronization methods obvious under § 103.
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 found the patent claims unpatentable under 35 U.S.C. § 103(a) based on various combinations of prior art references. The Petitioner successfully demonstrated that combining existing network technologies taught or rendered obvious the claimed limitations, particularly in multicast routing and packet processing.
Juniper Networks, Inc. v.Portsmouth Network Corporation
The PTAB granted institution for an IPR concerning network reconfiguration protocols, finding a reasonable likelihood of prevailing on the grounds of obviousness (103). The patent relates to methods for rapid link failure recovery in Switching/Routing Protocols (STP).
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.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.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
Cisco Systems successfully navigated a discretionary denial challenge at the PTAB, leading to the institution of an IPR against Portsmouth Network Corp. over network resource allocation claims. The Board found that Cisco demonstrated a reasonable likelihood of prevailing on at least one claim, despite arguments regarding prior art redundancy and pending district court litigation.
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.
