1. In the process of preliminary examination, the Patent Office considers that the application for a patent for invention-creation does not conform to the relevant provisions of the Patent Law and its detailed rules for implementation, and rejects it after stating opinions or making corrections;
2, in the substantive examination, the application for a patent for invention does not conform to the relevant provisions of the Patent Law and its implementing rules, and is rejected after being informed by the Chinese Patent Office of its statement or correction. There are two ways to deal with the rejection of a patent application:
1, choose to give up. If the patent application is unnecessary, the applicant can choose to give up applying for the patent after the patent application is rejected.
2. Request to reject the patent reexamination. Of course, if the applicant does not want to give up the patent, he can also apply for patent reexamination.
