GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
GlobalFoundries has filed an IPR petition challenging 21 claims of Oak IP’s ’691 patent covering metal‑semiconductor junctions. The petition relies on U.S. Patent No. 7,176,483 for anticipation and on a combination of that patent with U.S. Patent No. 7,727,882 for obviousness, while also raising written‑description and enablement issues.
NXP Semiconductors N .V. et al. v.Harbor Island Dynamic, LLC
Samsung and NXP successfully invalidated a large portion of Harbor Island Dynamic's patent portfolio in the IPR proceeding. The Board found multiple claims unpatentable based on anticipation (102) and obviousness (103) using prior art references like Yu, Okashita, and Burgener. This final decision significantly weakens the patent owner’s position in semiconductor device technology.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The PTAB denied institution of an IPR challenge brought by Micron Technology against Yangtze Memory Technologies regarding 3D memory device patents. The Board found the Petitioner failed to meet its burden of showing a reasonable likelihood of prevailing over prior art references.
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.
