Only the patent applicant has the right to initiate the patent reexamination procedure, and must submit it to the Patent Reexamination Committee of the State Intellectual Property Office within 3 months of receiving the rejection notice. According to the provisions of the Patent Law and its implementing rules, if a patent applicant is dissatisfied with the decision of the State Intellectual Property Office to reject the application, he may request a reexamination to the Patent Reexamination Board within three months from the date of receipt of the notice. The State Intellectual Property Office's decision to reject a patent application includes two situations: one is that after preliminary examination, the State Intellectual Property Office considers that the invention, utility model or design patent application does not comply with the provisions of the patent law and rejects it; the other is that After a substantive examination, the State Intellectual Property Office considered that the invention patent application did not comply with the provisions of the Patent Law and rejected it.

Modified patent application documents should be submitted in duplicate. The Patent Reexamination Board shall transfer the accepted reexamination request to the original examination department of the Patent Administration Department of the State Council for review. If the original examination department agrees to revoke the original decision based on the request of the reexamination requester, the Patent Reexamination Board shall make a reexamination decision accordingly and notify the reexamination requester. If, after conducting a reexamination, the Patent Reexamination Board considers that the reexamination request does not comply with the relevant provisions of the Patent Law and its Implementing Rules, it shall notify the reexamination requester and require him to state his opinions within a specified period. If there is no reply within the time limit, the reexamination request shall be deemed to have been withdrawn; after stating its opinions or making modifications, if the Patent Reexamination Board believes that it still does not comply with the relevant provisions of the Patent Law and its Implementing Rules, it shall make a reexamination decision to maintain the original rejection decision; Patent Reexamination After the review, if the committee believes that the original rejection decision does not comply with the relevant provisions of the Patent Law and its Implementing Rules, or if it believes that the revised patent application documents have eliminated the defects pointed out in the original rejection decision, it shall revoke the original rejection decision and let the original examination department continue.
