Dispute Summary
Micron Technology filed a Petition challenging the validity of Yangtze Memory Technologies' '031 Patent, arguing that key claims are obvious over prior art references Kim and Tessariol. The petition focuses on 3D NAND memory structures, specifically multi-stack staircase designs and etch profiles. Micron asserts that the combination of teachings from these references renders the claimed features predictable and non-novel.
