The protection period of utility model patent is shorter than that of invention?

China's patent law clearly stipulates that the protection period of utility model patents is 10 years, counting from the date of filing. The protection period of an invention patent is 20 years. In contrast, the protection period of utility model patents is much shorter than that of invention patents. This is because, generally speaking, the process of utility model creation is simpler and easier than invention creation, and the time to bring benefits into play is much shorter. Therefore, the provisions of the law on its protection period are correspondingly shorter.
