How long does it usually take from patent acceptance to authorization?

Legal analysis: it will be published 18 months from the date of acceptance, and then the actual trial stage will be carried out. It usually takes about 3 years to get authorization, but it does not rule out a longer time. In order to speed up the time limit for obtaining the patent right, we can apply for publicity in advance, so that it can be made public after passing the preliminary examination, and then enter the actual trial stage, which can speed up the progress of authorization.

Legal basis: Article 34 of the Patent Law of People's Republic of China (PRC). After receiving an application for a patent for invention, the administrative department for patent in the State Council, after preliminary examination, finds that it conforms to the provisions of this Law, and shall publish it within 18 months from the date of application. The patent administration department of the State Council may publish its application at an early date upon the request of the applicant.
