Three reexaminations mean as follows:
Three reexaminations refer to the three reexaminations conducted by the Patent Office during the review process of a patent application. These three reviews are substantive review review, authorization review review and invalidation review review. These reviews review the review results of patent applications to ensure the quality and validity of the patent.
The first reexamination is a substantive examination reexamination, which is conducted after the patent application has passed the preliminary examination. The purpose of substantive examination and reexamination is to review the patent claims of the invention to ensure that they comply with the requirements stipulated in the patent law. If the Patent Office believes that the patent application meets the requirements, it will issue a notice of substantive examination opinion, requiring the applicant to modify or supplement the patent requirements. If the patent application does not meet the requirements, a rejection notice will be issued.
The second reexamination is an authorized review reexamination, which is conducted after the patent application has undergone substantive examination. The purpose of authorization review is to review the authorization requirements of the patent right to ensure that they comply with the requirements stipulated in the patent law. If the Patent Office determines that the patent application meets the requirements, it will issue an authorization notice authorizing the applicant to possess patent rights. If the patent application does not meet the requirements, a rejection notice will be issued.
The third review is the invalidation review, which is conducted after the patent right has been granted. The purpose of invalidation review is to review the validity of the patent right and ensure that it meets the requirements stipulated in the Patent Law. If the Patent Office believes that the patent right is invalid, it will issue a notice of invalidation and revoke the patent right. If the patent right is valid, the validity of the patent right will be maintained.
In general, three-branch reexamination is an important measure to ensure the quality and validity of patent rights, and is of great significance for safeguarding the legitimate rights and interests of patentees and promoting technological innovation.
