Hello, how to correct the authorized utility model patent?

1. There is no amendment procedure for the granted patent. Specifically, in the preliminary examination, the examiner will conduct a comprehensive examination of the patent application with defects that can be overcome through correction in the application documents, and issue a notice of correction. So there is no need to correct it now.

It is impossible to change the attached drawing because it has been authorized.

3. If you want to change it to the correct attached drawings, my idea is to give priority and then submit the correct application documents. However, you'd better call the patent office to consult this method first.

Priority requirement means that the applicant requests the patent office to enjoy priority on the basis of its earlier patent application in accordance with the provisions of Article 29 of the Patent Law.

Article 29 of the Patent Law Where an applicant files a patent application for his invention or utility model with the Patent Administration Department of the State Council within 12 months from the date when he first filed a patent application in China, he may enjoy priority.
