Our litigation attorneys represent Japanese clients in key jurisdictions across the United States as well as in International Trade Commission (ITC) proceedings. There are a handful of Federal District Courts in which Japanese companies have most frequently been involved in patent litigation in recent years. The ITC is also a venue that commonly hears patent disputes involving Japanese companies, and in which Fish & Richardson regularly represents clients.

Our patent attorneys have extensive experience filing and prosecuting patent applications for international clients, including Japanese companies. We also handle reexamination, reissue, and interference proceedings in the United States Patent and Trademark Office (USPTO) for Japanese clients.

Attorneys from our Japan Team frequently visit Japan to work and strategize with our clients and to reinforce our commitment to their ongoing technological and business success. Members of our Japan Team also participate and hold leadership roles in key intellectual property associations relating to Japan, and we regularly present innovative seminars specifically designed for Japanese companies and their executives. Our attorneys have lectured on U.S. patent law and procedures at seminars in Japan that have been sponsored by the AIPPI Japan Group, the Japan Intellectual Property Association (JIPA), the Japan Patent Attorney Association (JPAA), and the Kansai Economic Federation.

Fish’s standing in the intellectual property arena is consistently recognized. In 2012, we have been named the #1 Overall Litigation firm and #1 IP Litigation firm for America’s largest corporations by Corporate Counsel, listed in the IAM Patent 1000 for National Patent Prosecution and Litigation Practices, and ranked in the Top Tier 1 National Rankings in Patent Prosecution and Patent Litigation by The Legal 500.

Focus in Japan

For decades, our attorneys have been visiting Japan to forge relationships and to bring value and expertise to Japanese companies. As a result of these efforts, we have had the privilege of representing well-known Japanese companies in a range of important intellectual property matters. We have also developed numerous professional relationships throughout Japan, including connections with several prominent Japanese law and patent firms. Even when our attorneys are not physically present in Japan, we use our constellation of connections and state-of-the-art technology to maintain contact and to work collaboratively with our Japan-based clients.

Our ongoing commitment to the Japanese legal market has resulted in the continual expansion of our Japan practice and the development of a team of attorneys who provide outstanding service to our Japan-based clients. Our Japan Team members are located in offices across the United States, allowing us immediate access to local information, courts, and key forums, including the ITC and USPTO in Washington, D.C. We maintain an in-house translator to support our Japan Team, and several attorneys and members of our professional support staff are fluent in Japanese.

Fish & Richardson is known for the quality of its thought leadership, as reflected in our frequent, insightful seminar participation, newsletters, and attorney blogs. Members of the Japan Team continually assess legal developments in the United States and overseas in terms of how they affect our Japanese clients, and we provide information and guidance to keep our clients in the best position possible.

We encourage our clients to visit our offices and to meet with as many members of the Japan Team as possible whenever they are in the United States. We are pleased to help clients and contacts with the logistics for their visits.
