Dispute Summary
Samsung Electronics filed an IPR petition seeking cancellation of claims 1‑4 of Maxell’s U.S. Patent 11,277,650. The petition argues the claims are obvious over three prior‑art references—Shindo, Sasaki, and a combination of Futa and McClellan—under 35 U.S.C. §103. The petition requests that all challenged claims be found unpatentable.
