Areas of Practice

Charles's practice focuses on patent prosecution and enforcement. He prepares and prosecutes hundreds of patent applications in the areas of semiconductors, LEDs, displays, wireless communications, robotics, software, cloud computing, artificial intelligence, and optical devices. He also participates in litigation in district courts and at the U.S. International Trade Commission (ITC), and proceedings before the U.S. Patent and Trademark Office. Dr. Huang counsels clients on portfolio management, due diligence, and patent invalidity and infringement issues.

Prior to law practice, Charles worked as an intellectual property manager for liquid crystal display manufacturing companies in Taiwan and mainland China. In those positions, he was responsible for analyzing several LCD-related patent portfolios, supervising litigations relating to U.S. patent rights, and negotiating patent acquisitions.
