Detailed Summary
In IPR2025‑00614, Kingston Technology Company, Inc., Kingston Technology Corporation, and Kingston Digital, Inc. seek to invalidate claims 1‑11 of U.S. Patent No. 8,891,298, which claims a hybrid memory system using distinct SLC and MLC NAND‑flash modules with wear‑leveling and error‑management features. The petition relies on obviousness grounds under 35 U.S.C. § 103, citing the Gavens, Moshayedi, and Sutardja references, among many incorporated patents and publications, to show that a person of ordinary skill would find the claimed subject matter obvious. It also addresses discretionary denial under §§ 314 and 325(d), contending that the Board should institute the proceeding. No institution decision has been made yet; the petition remains pending.
