Aylo Freesites Ltd et al. v.DISH Technologies L.L.C. et al.
The PTAB found that claims 1-11 of the patent were unpatentable over prior art references (Leaning, Klemets, Gamble) based on obviousness under 35 U.S.C. § 103. The Board adopted a limiting construction for 'to achieve continuous presentation,' requiring uninterrupted playback across quality shifts.
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.
Samsung Electronics Co., Ltd. et al. v.Empire Technology Development LLC
The PTAB found claims 25-28 unpatentable over Li and Siam, based on obviousness (103). The Board adopted a specific construction of 'idle power consumption' as power consumed while powered on and waiting to send data. However, the attempt to prove obviousness for claim 29 failed due to impermissible hindsight bias.
Ericsson Inc. et al. v.XR COMMUNICATIONS LLC
The PTAB issued a Final Written Decision finding all 17 challenged claims unpatentable under 35 U.S.C. § 103(a).
