Your Japanese Patent Attorney

Founder & Representative
Katsuyuki KOBAYASHI
Japanese Patent Attorney
I have been engaged in intellectual property practice for more than 30 years, handling both domestic and international IP matters.
I believe that good IP practice begins with understanding the client's business, not simply filing an application. I aim to provide practical and consistent support and to build long-term relationships with clients and overseas associates.
