Thomas L. Jarvis

Specialty / focus. Thomas L. Jarvis is a patent trial lawyer whose practice centers on complex technology litigation, with a distinctive concentration in U.S. International Trade Commission Section 337 investigations. His tracked matter — Longitude Licensing Ltd. v. Apple Inc. (defense-side, lead counsel, Finnegan) — involves semiconductor transistor/finFET process patents, consistent with his broader electronics docket. Published practice descriptions (Chambers, The Legal 500, IAM Patent 1000, IPWatchdog) show decades of work on smartphones/wireless communications, microprocessors, DSPs, memory, networking equipment, semiconductor fabrication and packaging, and software, plus occasional non-electronics technologies (medical devices, industrial equipment, alkaline batteries). He is a former Senior Investigative Attorney in the ITC's Office of Unfair Import Investigations (roughly 10 years there).

Side / firm context. The authoritative case list shows one appearance, entirely on the defendant side (0 plaintiff / 1 defendant). Jarvis primarily defends operating companies — including Apple, Comcast, Ericsson, and Research In Motion — in ITC and district court patent fights, though earlier in his career he also led offensive ITC cases for Asian manufacturers such as HTC, S3 Graphics, and VIA Technologies against Apple. He was an ITC litigator at Finnegan, Henderson, Farabow, Garrett & Dunner for many years (partner through July 2013), then moved with three partners to Winston & Strawn in August 2013, where he chairs the firm's ITC practice (still listed there in the 2025 Chambers Global guide). Note a sourcing wrinkle: his single tracked appearance is attributed to Finnegan, and some current directory listings also associate him with Finnegan, suggesting a possible return to that firm; the publicly available record is inconsistent on his current firm as of the search date.

Notable cases / outcomes. Public sources credit Jarvis with more than 60 Section 337 investigations and 150+ trial days as lead counsel. Highlights include leading multiple HTC/S3/VIA cases against Apple at the ITC; defending Research In Motion in the ITC matter that invalidated a Kodak imaging patent (after it had extracted large royalties from Korean handset makers); two Ericsson ITC cases against Apple that settled after trial; and Comcast's ITC defense against Rovi/TiVo through trial. His professional rankings include Chambers USA Band 1/leading recognition for Section 337 work over many years and The Legal 500 and IAM recognition as a leading ITC patent litigator.

PTAB / IPR and credentials. No public record indicates a regular IPR/PGR practice; his documented experience is district court and ITC litigation, although his firm (Finnegan) has handled related IPRs for other Longitude defendants. Education and bar-admission details could not be confirmed from reliable professional sources in the materials reviewed and are therefore omitted.
