Generally, it is 6-18 months. 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 issues such as novelty and creativity will be examined in the substantive examination stage. If there are some substantive defects that cannot be modified, or the conditions for authorization cannot be met after modification, it 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, actual examination and authorization announcement. Generally speaking, they will be published 18 months after acceptance, and then the actual examination stage. Generally, it will take about 3 years to obtain authorization, but it does not rule out a longer time. In order to speed up the time limit for obtaining the patent right, you can apply for making it public in advance, so that it will be published 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, you can also request to speed up the review, but the procedures are more complicated and the cost will be higher. As far as utility models and designs are concerned, they need to go through the stages of acceptance, preliminary examination and authorization announcement. Because there is no need for substantive examination, the time for obtaining authorization for utility models and designs is relatively short, generally from June to October. Legal objectivity:
