Microsoft Corporation v.EyesMatch Ltd.
The PTAB upheld all claims of the patent in this final written decision after rejecting multiple grounds of obviousness (103). The Board adopted specific claim constructions for 'mirror-mimicking' and 'varying rate,' finding the petitioner failed to meet its burden of proof.
Microsoft Corporation v.EyesMatch Ltd.
Google LLC successfully convinced the PTAB that all 18 challenged claims of EyesMatch Ltd.'s patent were unpatentable over various combinations of prior art references. The Board adopted a specific construction for 'mirror tracking mode,' which was central to finding obviousness across multiple grounds.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The PTAB denied Micron's IPR petition against Yangtze Memory because the patent owner had successfully filed a statutory disclaimer covering all challenged claims related to 3D memory devices.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology's IPR petition against Yangtze Memory Technologies was denied by the PTAB. The Board found that Micron failed to demonstrate a reasonable likelihood of prevailing on the merits, specifically regarding obviousness over prior art Costa in 3D memory technology.
