He is a member of the firm's Litigation Department and its Intellectual Property and Antitrust and Competition Practice Groups. His practice encompasses a broad range of intellectual property, antitrust, unfair competition, and complex commercial litigation matters.

Mr. Thomas's practice areas frequently involve patent and trade secret litigation, with a notable focus on life sciences, including Hatch-Waxman cases for pharmaceutical products. He has also handled matters involving semiconductors, electronics, consumer electronics, and telecommunications technology, as indicated by his representation in cases such as Greenthread, LLC v. ON Semiconductor Corporation et al. and Telcom Ventures LLC v. Apple Inc.

He has served as lead trial counsel in significant matters, including representing Hewlett-Packard Co. against Oracle Corp., which resulted in a complete victory for HP and a jury verdict awarding over $3 billion in damages. Other notable cases include securing a judgment in favor of Allergan, Inc. in a $600 million patent license interpretation dispute, Miotox v. Allergan, and successfully trying Allergan, Inc. v. Barr Laboratories, a Hatch-Waxman case where the patents were found valid and infringed, a ruling later affirmed by the Federal Circuit. He served as Lead Counsel in the tracked cases Telcom Ventures LLC v. Apple Inc. and an untitled case, and of counsel in Greenthread, LLC v. ON Semiconductor Corporation et al.

Mr. Thomas is admitted to practice in California and before several federal district courts and circuit courts, including the Federal Circuit.
