History



Isamu Hosoi was registered as a Patent Attorney in the Japanese Patent Office (JPO) in 1973, and established the Hosoi Patent Firm in Tokyo in 1975. In 1996, Hosoi joined forces with Japanese patent attorney Mr. Osamu Shimizu to form the firm Shimizu & Hosoi. In September 2007, Hosoi reorganized the firm as (in English) HOSOI & ASSOCIATES. “Ars” is the Latin for “art” in Ars Kokusai Tokkyo Jimusho (“Ars International Intellectual Property”), the Japanese name of the firm since September 2007.
