Time required from patent application to preliminary examination

Yes, the application for a patent for utility model only goes through one stage of examination, that is, preliminary examination, and once it is passed, it will be authorized.

If the patent application fee has been paid, it will take about 4-5 months from the submission of the patent application documents to the issuance of the preliminary examination results (that is, the patent office issues the authorization notice), and then it will take about two months for the applicant to obtain the patent certificate after completing the authorization registration.
