The application fee and annual fee for inventions are several times higher than those for utility models.

The protection period of the invention is 20 years,
The utility model is 10 year.
There is only formal examination of utility models, and besides formal examination, there is also substantive examination of inventions. In other words, it is easy to apply for a utility model, but its practicality is in doubt.
In addition, according to Article 9 of the Patent Law, only one patent right can be granted for the same invention-creation. However, if the same applicant applies for a patent for utility model and a patent for invention at the same time on the same day, and the patent for utility model obtained earlier has not been terminated, and the applicant abandons the patent for utility model, the patent for invention may be granted.
