Substantive examination stage: after the publication of the application for a patent for invention, if the applicant puts forward a request for substantive examination and it has taken effect, the applicant will enter the substantive examination procedure. If the applicant fails to make a request for real trial within three years from the date of application, or the request for real trial does not take effect, the application shall be deemed to have been withdrawn.
In the actual trial process, whether the patent application is novel, creative and practical will be comprehensively examined.

Failing to pay within the time limit shall be deemed to have withdrawn the application. If the substantive examination finds no reason for rejection, it shall enter the authorization procedure as required.
