Google LLC v.Proxense, LLC
Google LLC successfully argued that the challenged claims were obvious over multiple combinations of prior art (Dua, Giobbi ’157, Kotola, Buer). The PTAB instituted the IPR on all 20 challenged claims after rejecting the Patent Owner's narrow claim construction arguments. This sets up a significant trial phase regarding wireless security and digital key technology.
Samsung Electronics Co., Ltd. et al. v.XiFi Networks R&D, Inc.
The Board granted institution for the PGR proceeding involving Samsung and XiFi Networks, allowing the challenge to proceed based on likelihood of prevailing or unpatentability.

Apple Inc. successfully petitioned to institute IPR against Apex Beam Technologies LLC's patent 10,944,527, arguing the claims are obvious over prior art related to massive MIMO and beamforming.
Lenovo (United States), Inc. et al. v.Telefonaktiebolaget LM Ericsson et al.
Lenovo successfully convinced the PTAB to institute an IPR against Ericsson's patent (10425817) covering 5G security protocols. The Board found a reasonable likelihood of prevailing based on combinations of prior art references, leading to a trial proceeding.
Hewlett Packard Enterprise Company et al. v.Cobblestone Wireless LLC
The PTAB institution decision upheld the Petitioner's challenge of nine claims based on obviousness in wireless communication technology. The Board accepted that prior art disclosures, including IEEE standards and Shearer, support the claimed dual-frequency transmission structure.
AT&T Corp et al. v.Daingean Technologies Ltd.
The Board issued a Final Written Decision finding all challenged claims unpatentable. The patent relates to random access procedures in LTE/5G apparatuses and involved significant claim construction regarding power ramping functions.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully challenged Nokia's patent claims in an IPR proceeding regarding video coding and motion prediction technology. The Board found a reasonable likelihood of prevailing on the grounds of obviousness over prior art, leading to institution.
ASUSTeK Computer Inc. et al. v.Nokia Technologies Oy
The PTAB granted institution for IPR2025-01153, allowing ASUSTeK to challenge Nokia's patent 10536714 after demonstrating a reasonable likelihood of prevailing.
ASUSTeK Computer Inc. et al. v.Nokia Technologies Oy
The USPTO denied institution of IPR petitions filed by ASUSTeK against Nokia, preventing the trial on patentability issues.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully navigated the institution phase of its IPR against Nokia regarding video coding claims. The Board found a reasonable likelihood that Amazon could prove unpatentability under § 103, leading to the case being instituted for trial.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
The PTAB instituted the IPR, finding a reasonable likelihood of unpatentability for claims related to video compression and coding. The Board found that prior art references like Karczewicz and Frojdh, combined with H.263 standards, teach the claimed 'skip coding mode.'
Nokia of America Corporation et al. v.Iarnach Technologies Limited
Nokia of America Corporation et al.'s IPR petition against Iarnach Technologies Limited was denied by the PTAB, preventing trial on claims 1-11. The Board found that the combination of prior art references (G.984.3 and Khermosh) did not sufficiently teach or suggest the claimed method for managing upstream burst overhead parameters in PON systems.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications challenged Entropic's '008 patent claims, arguing they are obvious in light of prior art references like Renken and Cholas. The PTAB institution decision recognized the compelling unpatentability challenges presented by Comcast regarding signal monitoring technology.
DISH Network L.L.C. et al. v.Entropic Communications LLC
The PTAB denied institution of IPR for DISH Network against Entropic Communications, finding that the challenger failed to establish a reasonable likelihood of prevailing on grounds of obviousness. The challenge related to common bit-loading methods in broadband coaxial networks.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully challenged Nokia's video compression patent (8077991) in an IPR proceeding based on obviousness and anticipation grounds. The PTAB found a reasonable likelihood that Amazon would prevail, leading to the institution of trial on all contested claims.
Cox Communications, Inc. v.Entropic Communications LLC
Cox Communications' IPR challenge against Entropic Communications regarding network monitoring technology was denied by the PTAB. The Board found insufficient evidence to establish a reasonable likelihood of prevailing on grounds of obviousness over various prior art references.
Samsung Electronics Co., Ltd. et al. v.Empire Technology Development LLC
The PTAB denied institution of an IPR challenging five claims related to channel estimation in MIMO systems. The Board found that the petitioner failed to demonstrate a reasonable likelihood of prevailing against obviousness grounds over multiple prior art references.
Ericsson Inc. et al. v.XR COMMUNICATIONS LLC
The PTAB institution decision found a reasonable likelihood of prevailing for the Petitioner in its IPR against XR Communications LLC. The challenge focused on whether multi-beam directed signal systems were unpatentable under 35 U.S.C. § 103 using prior art references Agee and Butler.
Digital Global Systems, Inc. v.DeepSig, Inc.
Digital Global Systems successfully secured the institution of IPR against DeepSig's patent (11,018,704) over radio signal distortion correction claims, setting up a major technical dispute in cellular communications.
Samsung Electronics America, Inc. et al. v.Cobblestone Wireless LLC
The PTAB institution decision found a reasonable likelihood of success for Samsung Electronics America, Inc. in challenging Cobblestone Wireless LLC's patent (7924802). The Board preliminarily determined that the preamble 'in a wireless communication channel' is not limiting, allowing the IPR to proceed on grounds of obviousness (103) and anticipation (102).
Ericsson Inc. et al. v.XR COMMUNICATIONS LLC
