How long will the patent for invention be authorized after the substantive examination takes effect? The patent for invention is generally authorized about 6-18 months after the substantive examination takes effect. If there is no problem, it may be authorized in less than a year. However, there is no guarantee that authorization will be granted, because novelty, creativity and other issues will be examined at the substantive review stage. If there are some substantive defects that cannot be modified, or the conditions for authorization cannot be met after modification, they may be rejected. 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, practical examination and authorization announcement. Generally, 18 months from the date of acceptance will be announced, and then the practical examination stage will be carried out. Generally, about 3 years will be allowed to obtain authorization, but not excluding a longer time. In order to speed up the time limit for obtaining the patent right, we can apply for early disclosure. In this way, after passing the preliminary examination, we will publish it and then enter the actual examination stage, which can speed up the progress of authorization. In addition, in some special cases, the request for accelerated review can be made, but the procedures are complex and the cost will be high. As far as utility models and designs are concerned, they need to go through the stages of acceptance, preliminary examination and authorization announcement. Since no substantive examination is required, the time for utility models and designs to be authorized is relatively short, usually from June to October.
