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 general, it will be announced within 65,438+08 months after acceptance, and then the actual examination stage. 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. 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, the time for authorization of utility models and designs is relatively short, generally 6- 10 months.
