U.S. patent litigation attorney Kevin Su counsels the world’s leading brands. He helps clients protect their intellectual property and market share as he consistently wins cases for them in U.S. District Courts, appellate courts, at the Patent Trial and Appeal Board, and before the U.S. International Trade Commission.

In his practice emphasizing patent litigation in computer-related technologies, Kevin represents many leading-edge companies in U.S. courts, including clients from India, China, Germany, Taiwan, and South Korea, in addition to U.S. clients. He has played a leading role in major ITC investigations and trials that helped clients quickly and forcefully block imported products from infringing their IP.

He also has extensive trade secret litigation experience, both in asserting and defending breach of contract, misappropriation, and unfair competition claims.

Kevin has represented clients in patent infringement cases involving chemical, electrical, computer hardware and software, and Internet technologies, as well as semiconductors and medical devices.

As a fluent Mandarin speaker, Kevin offers client companies based in Greater China a powerful advantage – he readily understands and communicates easily with them.

In addition to his active patent litigation practice, Kevin helps junior, diverse attorneys launch their careers by recruiting and mentoring them through Students of Color job fairs and other events and organizations that support diversity in the legal profession. He is also involved in the Asian Bar Association. Coming to the aid of children in need of political asylum and immigration, Kevin provides pro bono representation through Kids In Need of Defense and the Political Asylum/Immigration Representation Project.
