6, the patent office issued a notice of authorization?
7. Does the applicant go through the formalities of obtaining a patent certificate?
8. It takes about 2-3 months to get the patent certificate, and the whole process lasts about 2 years. The specific time depends on the examiner's review speed and the applicant's detailed public information.
