I applied for a patent, but I didn't authorize it in the end.

Theoretically, the law does not restrict the applicant from repeatedly applying for a patent for the same technical scheme, but what is the purpose of the applicant's patent application? In general, the purpose of an applicant applying for a patent should be to protect the patented technical scheme with economic value as a patent at the legal level.

There may be two reasons why the patent application is ultimately not approved:

First, the technical scheme itself does not meet the substantive requirements of novelty, creativity and practicality required by patent authorization;

Second, the applicant does not meet the requirements of the patent law due to procedural reasons (such as the time limit for submitting documents and payment of fees). ) after filing a patent application.

If it is not authorized for the first reason, it is meaningless to apply again.

If the second reason is not authorized, it depends on whether the applicant's technical scheme has been made public before the final unauthorized result comes out. If it is made public, the re-application may still be rejected because of the loss of novelty; If it is not public, it can be authorized.

If the applicant must get a patent certificate, you might as well try both cases.
