Tokyo, one of the world’s most technologically advanced and populated urban centers, is home to Keisen Associates’ main office. We are located in Chiyoda Ward in the heart of Tokyo, near the Imperial Palace grounds. The office is a short distance from the Supreme Court and the Tokyo High Court, where District Court patent litigation cases are heard, and from the Japan Patent Office.
In Tokyo, our patent attorneys can have frequent exchanges with JPO officials at every stage of patent and trademark prosecution as well as contact Asian law firms with ease. Our Tokyo office works in every stage of Japanese intellectual property prosecution and litigation.
