According to China's Patent Law, the protection period of design patent right is 10 years, counting from the date of application. The protection period of design varies from country to country: the protection period of Japanese design is 15 years from the date of approval of registration; In Germany, the protection period is 20 years from the date of application; In Britain, the protection period is 5 years from the date of registration, which can be extended for 4 times for 5 years each time; In the United States, the protection period is 14 years from the date of issuance of the certificate; In France, the protection period is 25 years from the date of registration, which can be extended for another 25 years after the registrant declares. It can be seen that the protection period of design patents in China is relatively short compared with developed countries.
