Detailed Summary
Micron Technology, Inc. filed Petition IPR2025-00118 seeking inter partes review of claims 1‑14 of U.S. Patent No. 10,879,164 owned by Yangtze Memory Technologies. The petition asserts that the claimed integrated‑circuit electrostatic‑discharge bus structure is obvious in view of the prior‑art references Yoshinaga, Saint, and Haralabidis, combined with the knowledge of a person of ordinary skill. Micron also argues that there are no grounds for a §314(a) discretionary denial and that a §325(d) denial would be inappropriate, urging the Board to institute the proceeding and find the claims unpatentable.
