Legal analysis: The stages of invention patent application authorization include publicity, substantive examination and authorization. Rejection of an application for a patent for invention after its publication means that after the invention patent has entered the substantive examination, the administrative department for patent in the State Council considers that its application does not conform to the provisions of the patent law, and it still does not conform to the provisions of the patent law after the applicant has stated his opinions or made amendments, thus rejecting its patent application.
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 administrative department of the State Council to reject the application, he may, within three months from the date of receiving the notice, request a reexamination from the Patent Reexamination Board. If the patent applicant refuses to accept the reexamination decision of the Patent Reexamination Board, he may bring a lawsuit to the people's court within three months from the date of receiving the notice.
