Jason Lee Romrell

Jason Lee Romrell is a patent litigation attorney and a partner at Finnegan, Henderson, Farabow, Garrett & Dunner, where he formerly led the firm's appeals, issues, and legal strategy section. He focuses on high-stakes intellectual property disputes across both trial and appellate levels, representing clients before federal district courts, the Patent Trial and Appeal Board (PTAB), and the U.S. Court of Appeals for the Federal Circuit. His practice encompasses various technology areas, including wireless audio synchronization, voice recognition, and pharmaceuticals, as evidenced by his case work.

Romrell represents both patent owners and accused infringers. Although the initial case data listed him on the defendant side in Sonos, Inc. v. Implicit, LLC, subsequent Federal Circuit proceedings, styled Implicit, LLC v. Sonos, Inc., show him arguing for the appellant, Implicit, LLC, a non-practicing entity that asserted patents related to content rendering synchronization against Sonos. In this matter, the Federal Circuit affirmed the invalidity of the asserted patent claims, a decision that stemmed from inter partes review (IPR) proceedings. Furthermore, he secured a significant $240 million jury verdict for his client Promptu in a patent infringement lawsuit against Comcast, involving voice recognition technology.

He regularly appears before the PTAB and the Federal Circuit, reflecting extensive experience in post-grant review proceedings and appellate advocacy. He has also contributed to discussions and publications regarding Federal Circuit jurisdiction over PTAB appeals under the America Invents Act (AIA).

Prior to joining Finnegan, Romrell served as a judicial law clerk to the Honorable Sharon Prost at the Federal Circuit and to the Honorable Ronald M. Whyte at the U.S. District Court for the Northern District of California. He was admitted to the State Bar of California on December 22, 2009.
