Amazon.com, Inc. et al. v.Nokia Technologies Oy
The PTAB instituted an IPR challenge against Nokia's patent (8036273), allowing Amazon to proceed with its obviousness arguments. The Board found that the combination of prior art references TML6 and Fandrianto plausibly teaches the claimed sub-pixel interpolation methods.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully petitioned to institute IPR against Nokia's patent (7280599) regarding video compression and sub-pixel interpolation. The Board found sufficient evidence of obviousness over prior art references TML6 and Fandrianto, leading to the institution of all 51 challenged claims.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully petitioned the PTAB to challenge Nokia's video compression patents based on obviousness over prior art references TML6 and Fandrianto. The Board granted institution, finding that the Petitioner met the reasonable likelihood standard for unpatentability. This decision sets a significant precedent in challenging complex technical claims using combined software/hardware disclosures.
Apple Inc. v.S.M.R Innovations LTD et al.
The PTAB denied Apple's IPR petition against S.M.R Innovations, finding no reasonable likelihood that the 'apparatus for rerouting data' patent would be invalidated based on prior art references like Chihara and BluetoothSpec.
Apple Inc. v.S.M.R Innovations LTD et al.
Apple Inc.'s IPR challenge against S.M.R Innovations LTD et al. was instituted by the PTAB on grounds of obviousness (§ 103).

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.
DISH Network L.L.C. et al. v.Entropic Communications, LLC
DISH Network challenges the validity of patent 8621539, arguing that its claims are obvious by combining prior art from Hou, Konschak, and Dapper. The petitioner asserts that known techniques in broadband cable networking render the claimed methods predictable improvements.
DISH Network L.L.C. et al. v.Entropic Communications, LLC
