About AKEBONO INTERNATIONAL Kagurazaka Office
The history of AKEBONO INTERNATIONAL Kagurazaka Office spans over 90 years, and includes its founding as YASUHARA PATENT OFFICE in 1929 and reorganization into YASUHARA LAW & PATENT OFFICE in 1951. OLINASU ASSOCIATES was spun off from the law firm and established as an IP firm with highly experienced patent and trademark attorneys in October 2008. On November 1, 2022, OLINASU ASSOCIATES was renamed AKEBONO INTERNATIONAL Kagurazaka Office in order to reinforce our connection with AKEBONO INTERNATIONAL, an IP firm located in Shinjuku, Tokyo that has been working on patent and design registration on behalf of its clients since April 1992, as well as to leverage this enhanced level of cooperation in providing an even better level of service to our clients.
