The earliest country in the world to establish a patent system was the then Republic of Venice, which promulgated the world's first patent law on March 1474 19. For example, Galileo, a famous scientist, applied for a 20-year patent for the pumping irrigation machine he invented in this country.
Britain promulgated the monopoly law in 1624, which is called "the beginning of modern patent law". Its basic principles and some provisions have been followed by many countries when formulating patent laws. Therefore, it is considered that the history of modern patent system began with the promulgation of this monopoly law in Britain.
