Sonoda & Kobayashi IP Law was established in 1998 and since then, we have been representing a growing number of global companies with their IP needs, as well as Japanese domestic companies. Our high grant rate for patents and our winning record in litigation have provided us with an international reputation as one of the most reliable intellectual property law firms in Asia.

At Sonoda & Kobayashi, we understand the legal and linguistic barriers our foreign clients face when prosecuting and enforcing intellectual property rights in Japan. In order to help our clients overcome these barriers, we believe that, in addition to a thorough knowledge of international patent law and technology, an open-minded, non-culturally or linguistically biased approach is required.
