Kitazawa & Koizumi

Since its establishment on August 1, 1989, Kitazawa & Koizumi has been providing high-quality intellectual property services to clients in Japan and abroad, with a particular focus on the electrical and mechanical fields. Through close communication and thorough consultation with our clients, we carefully and precisely prepare patent specifications as well as intermediate documents, such as written arguments and amendments. Over the years, this approach has enabled us to build long-standing relationships of trust with our clients.

On September 16, 2016, marking the twenty-seventh anniversary of our founding, we reorganized as a Patent Professional Corporation in order to further strengthen our management structure and ensure sustainable operations. Following this reorganization, the firm is led by two Patent Attorneys who oversee management and operations under a stable and well-structured framework.

Building on our experience and practical expertise in foreign patent prosecution, we remain committed to serving as a reliable partner in developing and implementing intellectual property strategies from both domestic and international perspectives. We sincerely appreciate your continued trust and support.
