Failure to make a request for substantive examination within the prescribed time limit shall be deemed as withdrawal of the patent application, and the patent application shall be invalid;
If a substantive review request is made, it will enter the review stage, and the final result will be authorized and not authorized. Needless to say, authorization; If it is not authorized, the patent office will also issue a notice of rejection, indicating that the patent application is invalid (this process depends on the specific circumstances of substantive examination, long or short).
So in either case, there will be an authorized or unauthorized final result. After authorization, the patent protection period is 20 years from the date of application (annual fee needs to be paid continuously); Without authorization, the patent is invalid from the date of application and has no protection period.
Even without authorization, others can't apply for a patent for the same technology, because the technology has been made public, which will destroy the novelty of later applications.
