The PTAB denied an IPR petition filed by a consortium of wireless carriers against ASUS Technology Licensing Inc., citing unfavorable findings under the Fintiv discretionary denial standard. The Board found that despite some neutral factors, Petitioner's substantial delay and lack of compelling merits weighed against proceeding with the case.
Ericsson Inc. et al. v.Active Wireless Technologies LLC
Ericsson and Nokia successfully petitioned against Active Wireless Technologies' patent (10785764) in a PTAB decision, leading to institution. The Board found a likelihood of prevailing on the Shin obviousness ground over NB-IoT/LTE multicast services claims.
Ericsson Inc. et al. v.Active Wireless Technologies LLC
Ericsson and Nokia successfully petitioned to institute an IPR against Active Wireless Technologies LLC regarding 5G NR PUCCH design claims. The Board found compelling evidence of unpatentability, despite initial concerns raised by the Patent Owner's arguments.
Intel Corporation et al. v.TELEFONAKTIEBOLAGET L M ERICSSON et al.
Intel Corporation initiated this Petition challenging the validity of Ericsson's patent (7151430), asserting that all 21 claims are obvious over various combinations of prior art. The petitioner relies heavily on Taniguchi, Midya, and Raghavan to demonstrate that claimed features in inductive coupling/antenna design were already known or suggested.
Intel Corporation et al. v.TELEFONAKTIEBOLAGET L M ERICSSON et al.
The PTAB found multiple claims of the '430 patent unpatentable over prior art, primarily Taniguchi. The Board adopted Petitioner's construction that key claim terms were not limiting, supporting obviousness findings across several grounds.
AT&T Corp et al. v.Daingean Technologies Ltd.
Daingean Technologies Ltd. opposes AT&T and other petitioners’ IPR request on U.S. Patent 11,196,509, asserting that the cited Lee and Zheng references fail to teach the patent’s specific code‑block sizing and grouping features, and that the petition relies on hindsight.
AT&T Corp et al. v.Daingean Technologies Ltd.
AT&T and its partners filed a Petition challenging Daingean Technologies' '400 Patent, asserting that claims 5, 7, and 8 are anticipated or obvious by the prior art reference R2-1702708. The challenge focuses on dual-connectivity/5G standards, arguing that an Ericsson technical contribution discloses all elements of the challenged claims. This is a critical early stage attack in ongoing litigation against Daingean Technologies.
AT&T Corp et al. v.Daingean Technologies Ltd.
The PTAB denied AT&T's IPR against Daingean Technologies, finding that the Petitioner failed to show a reasonable likelihood of success regarding claims related to code block segmentation and HARQ-ACKs. The denial hinged on insufficient support for the 'multiple CB/CBG limitation' in both cited prior art references.
AT&T Corp et al. v.Daingean Technologies Ltd.
The PTAB denied institution of IPR against Daingean Technologies' patent, finding that the petitioner failed to prove its sole prior art reference (R2-1702708) was a publicly accessible printed publication.

The PTAB denied Amazon's request for Director Review of the institution decision in IPR2024-00691, leaving Nokia's patent institution intact.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon challenges Nokia's video coding patents (8,050,321) in an IPR petition, arguing that the claims are obvious over established standards like MPEG-1 and prior art references such as Kim and Yagasaki. The petitioner asserts that existing technologies render the core inventive concepts of the patent predictable.
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.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
The PTAB granted institution for the patent covering video coding methods related to grouping image frames. The petitioner successfully argued that the claims are obvious over prior art references like MPEG-1, Yagasaki, and Kim.
