The firm: Nakamura & Partners was established as a patent and law firm in 1914 by patent attorney Morio Nakamatsu, who served as the ninth commissioner of the Japanese Patent Office from 1907-13. In 1946 the eldest son of Morio Nakamatsu, Kannosuke Nakamatsu, succeeded his father at the firm. Kannosuke Nakamatsu was deeply involved in public activities and held many prestigious positions, including acting president of Dai-ni Tokyo Bar Association, president of the Japan Patent Attorneys’ Association and president of the Japan Federation of Bar Associations. In 1963 the firm was reorganised as a partnership. In 1983 the firm was renamed Nakamura & Partners, ushering in a period of rapid expansion. From 1987-1992, Minoru Nakamura, Kazuko Matsuo and Fumiaki Otsuka acted as representative partners of the firm. From 1993-97, Fumiaki Otsuka, Kaichi Shishido and Yoshio Kumakura acted as representative partners. From 1998-2007, Yoshio Kumakura acted as a representative partner. From 2008-10 Koichi Tsujii and Nobuo Ogawa acted as representative partners. From 2011-14, Koichi Tsujii, Atsushi Hakoda and Takaki Nishijima acted as representative partners. Since 2017, Shin-ichiro Tanaka, Kazuhiko Yoshida and Takeshi Deshimaru have been acting as representative partners for all other partners and associates at the firm (including 19 attorneys-at-law and more than 60 patent attorneys).
