What is the time from the application to the next revision of the utility model patent?

Hello! At present, it is the fastest to submit a paper application directly to the acceptance window, and you can get the acceptance notice on the spot. The approval time is the same. After receiving the notice, you need to mail the electronic application, at least 1 week. The shortest time from application to obtaining the certificate of the utility model is 6 months. It takes at least 1 month and a half to 2 months to correct once. The license is usually issued after receiving the authorization notice of 1.5 months. I received the authorization notice in more than 3 months, and got another utility model certificate in 6 months.
