工業所有権の保護に関するパリ条約
The first patent law in Japan was thus established in 1871, though it was abandoned in the next year. Today, the founding date of Japanese patent law and of the Japan's patent office is considered to be April 18, 1885, when the "Patent Monopoly Act" (專賣特許條例 "senbai tokkyo jōrei") was enacted. In 1899, Japan acceded to the Paris Convention for the Protection of Industrial Property. Takahashi Korekiyo was the first commissioner of the JPO.
