Legal analysis: there is no clear time limit for authorization. For invention patents, except for some invention patents that need to be kept confidential, general invention patents need to go through the stages of acceptance, preliminary examination, publication, actual examination and authorization announcement. 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. In addition, in some special circumstances, it may be required to speed up the audit, but the procedures are more complicated and the cost will be higher. As far as utility model and design are concerned, it needs to go through the stages of acceptance, preliminary examination and authorization announcement. Because there is no need for substantive examination, it takes a short time for utility models and designs to be authorized.
Legal basis: Article 54 of the Detailed Rules for the Implementation of the Patent Law. After the patent administrative department of the State Council issued the notice of granting the patent right, the applicant shall go through the registration formalities within 2 months from the date of receiving the notice. Where the applicant goes through the registration formalities on schedule, the patent administrative department of the State Council shall grant the patent right, issue the patent certificate and make an announcement.
