Short Summary
Headwater Research filed a response to Samsung’s request for Director Review of the PTAB’s denial of institution. The patent owner argues the Vidal Memo recission was proper, the change‑in‑position doctrine does not apply, and discretionary denial is statutorily authorized.
Detailed Summary
In the response to Samsung Electronics’ request for Director Review, Headwater Research contends that the PTAB’s recission of the Vidal Memo was proper because the memo was an improperly issued substantive rule under the APA. The patent owner further argues that the change‑in‑position doctrine is inapplicable since no reliance interests were created, and that the PTAB’s discretionary denial framework is expressly permitted by 35 U.S.C. § 314(a) and does not require a stipulation or alter the statutory IPR deadline. Citing numerous cases and statutory authority, Headwater maintains that the Director’s denial of institution was lawful and should be upheld.
