Samsung Electronics Co., Ltd. et al. v.Advanced Coding Technologies, LLC
The PTAB instituted an IPR challenging Samsung's patent claims against Advanced Coding Technologies over video compression technology. The Board found that the petitioner sufficiently explained how prior art combined to teach key claimed elements, leading to institution on all claims.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
Amazon challenged Nokia's video coding patent (7532808) at the PTAB, arguing that the claims are obvious over prior art references like Karczewicz and Frojdh. The Board found a reasonable likelihood of unpatentability for several claims, supporting Amazon’s position on key skip coding mode limitations.
Cisco Systems, Inc. v.VIDEO SOLUTIONS PTE. LTD.
Cisco Systems, Inc. filed a Petition challenging the validity of patent 8649426 owned by VIDEO SOLUTIONS PTE. LTD., asserting that the claims are obvious under 35 U.S.C. § 103. The petitioner argues that prior art references Perlman and Oguz teach known solutions for reducing video encoding latency, rendering the claimed methods unpatentable.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon challenged Nokia's hybrid video coding patents at the PTAB, arguing they are obvious combinations of known techniques found in Koga, Lin, and Narroschke. The petition focuses heavily on how combining transform and spatial domain methods is predictable within modern compression standards.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon filed an IPR challenging Nokia Technologies Oy's patents related to hybrid video coding and prediction error encoding. The petition argues that the challenged claims are obvious over combinations of prior art references, specifically Koga, Lin, and Narroschke. Petitioners assert these combinations teach predictable improvements in codec implementation.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
Intel Corporation et al. filed an IPR petition challenging Ericsson's patent on deblocking filter features, asserting obviousness over various prior art references. The core arguments focus on how asymmetric decision-making and specific offset equations are routine modifications of existing video compression techniques.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
Intel and others challenged Ericsson's '659 Patent, arguing that its deblocking filter equations are obvious over prior art references like Fu and Bjontegaard. The petition asserts that a Person Having Ordinary Skill in the Art would have routinely optimized the claimed coefficients using existing knowledge of high-pass filters.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Nokia Technologies Oy faces an Inter Partes Review challenge regarding its video compression patents, specifically concerning sub-pixel interpolation methods. The petitioner argues that combining TML6 and Fandrianto renders the claimed method obvious to a Person Having Ordinary Skill in the Art (POSITA). This proceeding centers on whether the combination of prior art references meets the 103 obviousness standard.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon has initiated an Inter Partes Review (IPR) challenging 51 claims of Nokia's U.S. Patent No. 7,280,599. The core dispute centers on whether the patent claims related to sub-pixel interpolation in video compression are obvious over prior art references TML6 and Fandrianto.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully instituted an IPR against Nokia regarding video compression standards, arguing that MPEG-1 teaches or suggests the claimed quantization methods. The Board found a reasonable likelihood of success despite initial claim construction disputes over sequence vs. picture parameters.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
Amazon has filed a petition challenging Nokia's video compression patent (7,532,808) at the PTAB. The petitioner asserts that the challenged claims are obvious under Section 103 over prior art references including Karczewicz, Frojdh, and H.263. This action targets core technology related to motion estimation and coding.
AMAZON.COM, INC. et al. v.Nokia Technologies Oy
Amazon has filed an IPR petition challenging Nokia's '808 patent, asserting that its skip coding mode is obvious over existing prior art references. The challenge focuses on whether combining zero-motion vector (ZMV) and non-zero motion vector (PNZMV) modes constitutes a predictable combination of known techniques in video compression. This dispute involves complex technical arguments regarding standard-setting technologies.
