We assist clients, particularly companies based in North America and Europe, in obtaining patent protection in Japan. With extensive experience representing international clients, we provide seamless support in English throughout the patent prosecution process. We also support Japanese companies in securing patent protection overseas through close coordination with local counsel in jurisdictions around the world.

We have particular experience in pharmaceuticals and life sciences, chemistry and materials, healthcare, and medical devices and related technologies. Our professionals include patent attorneys with experience in patent examination and appeal proceedings at the Japan Patent Office, as well as patent attorneys with research and development experience in industry. This diverse background enables us to provide highly sophisticated intellectual property services supported by deep technical understanding.

One of our strengths lies not only in understanding complex technologies, but also in developing patent strategies that contribute to our clients’ business growth and enhance corporate value. By combining our technical expertise with insights into the examination practices of the Japan Patent Office, we are able to pursue more effective patent protection tailored to our clients’ business objectives.

In addition, several of our patent attorneys have experience in intellectual property litigation before the Intellectual Property High Court and district courts in Japan. Our professionals also include individuals who have been involved in intellectual property policymaking and international negotiations concerning intellectual property matters. Drawing upon these diverse perspectives and extensive experience, we provide comprehensive support for our clients’ acquisition and enforcement of intellectual property rights, as well as their business development and expansion in Japan.
