International Practice

We have extensive international experience. We assist foreign clients in obtaining and enforcing intellectual property rights in Japan. We coordinate the Japanese prosecution with the filing and prosecution of corresponding applications around the world, particularly in the US, Europe and Asia.

Legal and Technical Consultation
