It takes about 18 months from preliminary examination to announcement of a patent.
Patent application time
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. Under normal circumstances, an announcement will be made 18 months after acceptance, and then the actual review stage will be carried out. Generally, it will take about 3 years to obtain authorization, but longer time is not excluded. In order to speed up the time limit for obtaining patent rights, you can apply for early disclosure, so that after passing the preliminary examination, it will be announced and then enter the practical examination stage, which can speed up the authorization process. In addition, in some special circumstances, you can also request for accelerated review, but the procedures are more complicated and the fees will be higher.
For utility models and designs, they need to go through the acceptance, preliminary review and authorization announcement stages. Since substantive examination is not required, the time for utility models and designs to be authorized is shorter, generally 6 -October.
