If you think that the examiner's opinion is unreasonable, you can make a request for reexamination within 3 months after receiving the notice of rejection decision, and pay the formal fee for reexamination. 2, after the review, if the rejection results remain unchanged, you can take the patent office review and invalid trial department as the defendant to the court.

After the review, the patent administration department in the State Council shall make a decision and notify the patent applicant.
