Short Summary
Samsung has filed a Petition for Director Review challenging the USPTO’s denial of institution for IPR 2025‑00482, arguing the agency’s retroactive policy change violates due process, the APA, and statutory limits.
Detailed Summary
In Petition for Director Review, Samsung Electronics contests the USPTO’s denial of institution for IPR 2025‑00482 covering patent 11,405,429. Samsung contends that the Acting Director’s retroactive rescission of the 2022 Vidal Memo— which had limited discretionary denial based on parallel litigation— violates the Fifth Amendment due process rights and the Administrative Procedure Act. The petition further asserts that the rescission breaches the change‑in‑position doctrine, unlawfully rewrites statutory deadlines and estoppel provisions, and is unconstitutionally vague. Samsung also argues that the rescission should have been subject to notice‑and‑comment rulemaking. The petitioner seeks reversal of the denial and a merits review of the IPR.
