How long can the patent be authorized after the actual trial?

Legal analysis: 6- 18 months. Because in the substantive examination stage, it usually takes one or more different examinations and defenses, the actual time for each patent to be authorized is different.

Legal basis: Article 35 of the Patent Law of People's Republic of China (PRC). Within three 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substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn.
