Firm Profile

Kuzuwa & Partners, P.C. was founded in 1995 as Kuzuwa & Partners, taking over the predecessor Takao Minami Patent Office.
Since then, we have learned a lot and grown significantly not only through works assigned by domestic companies/research institutions, as well as collaborative work with IP law firms around the world including Western and Asian countries, but also through work directly assigned by many Western companies/research institutions.
In April 2023, we were reborn as a more stable and sustainable professional corporation.
In alliance with “Kuzuwa Law Office”, which has been co-established at this opportunity, we are propelling a wider range of advanced and strategic IP services.
Our firm will provide services with higher customer satisfaction in an environment reasonably suited also to teleworks in the Nishi-Shinjuku Mitsui Building, a 27-story blue-green glass building in a corner of the central Tokyo office area, Nishi-Shinjuku.
