One of the few Japanese speaking U.S. litigators based in Japan, Mac Fox handles intellectual property infringement litigation, licensing, and counseling matters and represents clients ranging from electronics manufacturers to life sciences companies. He practiced in Los Angeles for nearly a decade before relocating to Tokyo in 2006. Mac has litigated cases throughout the U.S. and has experience before the International Trade Commission and Federal Circuit. He also has represented clients in commercial disputes and has experience in litigation related to cartel investigations.

Mac’s recent experience includes defending Japanese companies in multipatent cases involving telecommunications and network security technology, litigations involving technology relating to chipsets used in mobile handsets, and patent infringement litigation involving technology used in LCD and DLP projectors. He also has represented branded pharmaceutical companies in enforcing their patent rights through ANDA litigation under the Hatch-Waxman Act.

Mac frequently speaks on IP law and has lectured to the Japan Patent Attorneys Association and to the Chung Hwa Research Institute in Taiwan. He has guest lectured as part of an IP law course at Keio University. In 2015, he was invited to participate in a mock oral argument before the chief judge of the Federal Circuit Court of Appeals at a symposium in Tokyo celebrating the 10th anniversary of the creation of Japan’s Intellectual Property High Court.

He is a member of the Daini Tokyo Bar Association, American Bar Association, and American Intellectual Property Law Association and has served as a master of the Tokyo IP American Inn of Court.
