IPR2024-00828

Detailed Summary

In IPR2024‑00828, Maxell, Ltd. petitions the PTAB Director to vacate the final written decision that declared all twelve challenged claims of U.S. Patent 8,982,086 unpatentable. Maxell asserts that the Board misinterpreted the term “registering modes,” improperly applied prior‑art references (Rogers, Rosenberg, Bayram, Miyazawa), and ignored the patent’s extensive prior reexamination history, rendering the institution of the IPR contrary to 35 U.S.C. §325(d) and the Fintiv precedent. The petition emphasizes inconsistent expert testimony from Samsung and urges reversal of the decision and termination of the proceeding.
