Short Summary
Kangxi Communications seeks Director Review of the PTAB’s discretionary denial to institute an IPR against Skyworks’ RF front‑end patent, arguing that retroactive policy changes violated due process. The petition focuses on the withdrawal of prior‑art defenses in a parallel ITC case and the newly‑created “settled expectations” doctrine.
Detailed Summary
In a petition for Director Review, Kangxi Communications Technologies challenges the PTAB’s discretionary denial to institute an Inter Partes Review of Skyworks Solutions’ U.S. Patent 8,717,101 covering wireless front‑end modules. The petitioner argues that the Board improperly applied the Fintiv factors to a parallel ITC proceeding after the Vidal Memo was rescinded, and that a newly announced “settled expectations” doctrine was applied retroactively, violating the Fifth Amendment due‑process clause. Kangxi also contends that its withdrawal of prior‑art invalidity defenses from the ITC case constitutes a material change in circumstances that should have prompted institution. The request seeks reversal of the denial and referral of the petition for merits review.
