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.
Daingean Technologies Ltd. opposes AT&T and co‑petitioners' IPR petition on U.S. Patent 11,134,400, arguing the cited reference is not prior art and fails to teach the claimed SRB configurations, urging the Board to deny institution.
AT&T Corp et al. v.Daingean Technologies Ltd.
Multiple major carriers (AT&T, Ericsson, T-Mobile) filed a Petition challenging Daingean Technologies' patent covering base station apparatus for transport block segmentation. The challengers argue the claims are anticipated and obvious under 35 U.S.C. § 102/103 using prior art references Lee and Zheng.
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.

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.
