How long will the substantive examination authorization take effect?

Legal analysis: Patent substantive examination generally takes six to eighteen months, but the specific time depends on the content of the invention, the examiner's understanding of the invention, the examiner's work arrangement, and the time between the examiner and the applicant or his agent. The so-called substantive examination means that the State Patent Office examines the novelty, creativity, practicality and other substantive contents of the invention-creation for which a patent is applied. Within 3 years from the date of application, the State Patent Office may, upon the request of the applicant at any time, conduct a substantive examination of the application.

Legal basis: People's Republic of China (PRC) Patent Law.

Article 35 Within 3 years from the date of filing, the administrative department for patent in the State Council may, upon the request of the applicant at any time, make a substantive examination of the application; If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. The patent administrative department of the State Council may, when it deems it necessary, examine the application for a patent for invention on its own.

Article 39 If the application for a patent for invention is not found to be rejected after substantive examination, the administrative department for patent in the State Council shall make a decision to grant a patent right for invention, issue a patent certificate for invention, and register and announce it at the same time. The invention patent right shall take effect as of the date of announcement.
