If you don’t care about the application date, just submit a new application. If you want to keep the original application date, you need to pay a restoration fee of 1,000 yuan.
Under normal circumstances, utility model patents can be authorized 4-6 months from the date of application. After authorization, you need to pay the authorization registration fee and annual fee. After payment is completed, there are still about 3 months to issue the certificate.
If there are problems with the application documents, they need to be corrected. The correction time is usually 2 months. After you submit it, if there is no problem, it will be authorized soon. If there is a problem, it may have to be repaired, but it’s hard to say the specific time. But you should be able to get the certificate within a year.
