What is the earliest patent law?

Patents germinated in Britain. 1236, King Henry III of England granted a Bordeaux citizen the privilege of making all kinds of colorful fabrics for 15; 133 1 year, King Edward III of England granted Flemish John Kemp the exclusive right to weave and dye cloth. 1367, two watchmakers are licensed to operate. The earliest patent system in the world was established in Venice and the United States. 1474, Venice and People's Republic of China (PRC) formulated the world's first patent law and issued the world's first patent according to law. Galileo galilei, a scientist, has been granted the patent right of pumps in Venice and China for 20 years. 1642, Britain promulgated the monopoly law, and after Britain, other capitalist countries successively promulgated the patent law. For example, the year of America 1790, France 179 1, Germany 1877 and Japan 1885. After World War II, many developing countries in Asia, Africa and Latin America also formulated their own patent laws. At the same time, in order to promote international cooperation and exchanges, many international treaties and organizations have emerged, such as the Paris Convention for the Protection of Industrial Property, the Patent Cooperation Treaty, the European Patent Treaty, the World Intellectual Property Organization and the European Patent Office. It is necessary to talk about the origin and development of China's patent system. During the Guangxu period of the Qing Dynasty (1882), the layout of Shanghai weaving won the monopoly right of "within ten years, only Chinese businessmen are allowed to set up joint-stock companies, and other companies are not allowed to set up bureaus"; 1895, the capitalist Zhang Jian obtained the privilege of duty-free operation in Tongzhou, Suiming and Haimen. 1889, Emperor Guangxu promulgated the Articles of Association for Awarding Awards for Revitalizing Craft. The real patent system was established in 19 12 after the Revolution of 1911, and the Ministry of Industry and Commerce promulgated the Provisional Regulations on Award Technology. From 65438 to 0944, the Kuomintang government promulgated the patent law. After the birth of New China, the Central People's Government promulgated No.65438-0950 Provisional Regulations on the Protection of Invention Rights and Patent Rights. Especially after the reform and opening up, China's patent industry has developed vigorously. On March 1984, the National People's Congress Standing Committee (NPCSC) passed the patent law, which was formally implemented on April 1985. The number of patent applications in China is increasing year by year, with 1998 exceeding1200,000, making it one of the few patent powers in the world. 1984, the patent law promulgated by China and the earliest Venetian patent law formulated in 1474 were exhibited in an exhibition of the history of inventions and creations of the World Intellectual Property Organization, which showed that China's patent cause was well received by the world public.
