Andrew N. Thomases


Andrew Thomases is co-head of the firm's technology, media & telecommunications group and a nationally-recognized, first-chair trial lawyer with over 20 years of experience litigating complex patent and trade secret cases in federal courts throughout the country, as well as before the International Trade Commission. He has achieved numerous successes for companies in the fields of computer technology, semiconductors, analog circuits, wireless technology and medical devices, among other areas.

Andrew recently served as lead counsel for flash memory chip maker Spansion in a large set of multi-patent litigations against its rival Macronix International. Andrew’s representation included four ITC investigations, three district court cases, eleven inter partes review proceedings before the U.S. Patent Office, and coordination of multiple patent litigations in Germany. After two successful trials before the ITC, and after obtaining sanctions against Macronix, the litigations settled favorably for Spansion.

As a first-chair litigator, Andrew also obtained a complete defense decision at the ITC for Advanced Analogic Technologies, Inc., a semiconductor device company, and supported that decision in two appeals before the U.S. Court of Appeals for the Federal Circuit. He was also a key member of a team that obtained a $57 million-plus jury verdict on behalf of a global leader in medical technology, services, and solutions – one of 2009’s largest plaintiff verdicts in California. He has extensive experience in many U.S. district courts, including the Eastern District of Texas, the Districts of California, and the District of Delaware.

Andrew has been recognized as a “leading lawyer” in patent litigation by Chambers USA: America’s Leading Lawyers for Business and has been named among the “Top IP Litigators” in California by the Daily Journal. He has also been recognized by The Legal 500 (U.S.) for his record of successfully representing clients before the ITC.
