AT&T Services Inc. et al. v.Innovative Sonic Limited
AT&T Services Inc. failed to convince the PTAB that its claims were unpatentable over prior art references Centonza and Han. The Board denied institution, finding no reasonable likelihood of prevailing on either anticipation or obviousness grounds. This decision maintains the validity of Innovative Sonic Limited's patent in cellular network connectivity.
Ericsson Inc. et al. v.Active Wireless Technologies LLC
The PTAB granted institution for Ericsson Inc. et al.'s IPR challenge against Active Wireless Technologies LLC, finding compelling evidence of unpatentability under 102 and 103.

Nokia of America Corporation et al. v.Iarnach Technologies Limited
Nokia filed a petition challenging claims in the '892 Patent, asserting obviousness under 35 U.S.C. §103. The challenge focuses on combining prior art standards (ITU-T) and publications to demonstrate that claimed power management features are predictable.
Nokia of America Corporation et al. v.Iarnach Technologies Limited
Petitioners challenged U.S. Patent No. 9,806,892 in a PTAB petition, arguing that several claims related to power management in optical networks are obvious under 35 U.S.C. §103.

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.

Nokia of America Corporation et al. v.Iarnach Technologies Limited
The PTAB found several claims of the patent unpatentable based on obviousness over combinations of prior art standards (G.987.3, G.988) and publications (Röger). The Board specifically determined that Claim 1 was obvious because the combination suggested direct transitions between low-power states for increased energy efficiency.
Siemens Mobility, Inc. et al. v.Metrom Rail, LLC
Siemens Mobility and co‑petitioners seek Director review of a PTAB decision denying institution of an IPR on their UWB train‑control patent. They argue the Board wrongly treated a cited patent number as previously presented art and erred in finding the prior art was substantially the same as that considered during prosecution.

The Board found a material error in the Office's review of the evidence, allowing the IPR to proceed to trial.
MediaTek Inc. et al. v.ParkerVision, Inc.
MediaTek Inc.'s IPR petition against ParkerVision, Inc. was instituted by the PTAB, establishing a reasonable likelihood of prevailing on obviousness grounds. The petitioner successfully argued that combining Nevo and Avitabile renders claims 1-20 unpatentable in wireless communication systems.
Aylo Freesites Ltd et al. v.DISH Technologies L.L.C. et al.
