Message from Chair, the founder of TAKASHIMA International Patent Office

In 1980, I, Hajime TAKASHIMA, founded TAKASHIMA International Patent Office after long years of experience in the intellectual property department of the leading pharmaceutical company in Japan. Since then, my center of focus has always been the efficient provision of highly professional legal services covering all fields of intellectual property (IP) matters, and I held commitment to contributing to the best interests of our clients. Through professional performance, my firm has earned the trust of a number of Japanese companies as well as foreign ones, and grown into one of the leading patent firms in Japan.

With exponentially advancing technologies over a broad range of fields, the demand on highly sophisticated legal services in the IP matters has been increasing. The experts of various fields in Takashima International Patent Office, who have extensive experience in patent laws, work cooperatively and dynamically to meet the demanding intellectual protection needs of clients and achieve the maximum IP protection possible.

TAKASHIMA International Patent Office has an IP network around the world (we have business relationship with more than 600 patent firms throughout the world), and is strongly capable of handling matters outside Japan. TAKASHIMA International Patent Office provides best legal services both in Japan and abroad.

I and each member of TAKASHIMA International Patent Office are determined to strive to be an outstanding and trusted international patent firm for clients around the world.
