Legal analysis: 1, patent rejection and reexamination can only be conducted once, and the reexamination board has only 1 chance to reply or amend. 2, the review process itself is a remedy for the decision of the review department to reject, in the review request and reply to the review, you can modify the claim and state the patent reasons; However, for the same rejection decision, only one opportunity is given to pass the review relief. If you refuse to accept the review decision, you can only file an administrative lawsuit, and the result of the lawsuit is generally to maintain the review decision, or to revoke the judgment and make a new review decision (in the latter case, there will be more than one review decision, but it should not be considered as two reviews; It is a review that has produced more than two review decisions through litigation, and the subsequent review decisions are actually equivalent to revoking the previous review decisions, and only the last one is valid).
Legal basis: Article 41 of the Patent Law of People's Republic of China (PRC). If the patent applicant refuses to accept the decision of the patent administration department in the State Council to reject the application, he may request a reexamination to the patent administration department in the State Council within three months from the date of receiving the notice. After the review, the patent administration department in the State Council shall make a decision and notify the patent applicant. If the patent applicant refuses to accept the reexamination decision of the patent administrative department of the State Council, he may bring a lawsuit to the people's court within three months from the date of receiving the notice.
