Patent payment certificate

That depends on whether your application documents meet the requirements of the patent law. Judging from the 75 pieces submitted by Yuan You, a patent for utility model or design should be submitted. These two kinds of patents are not subject to substantive investigation. As long as there are no substantive defects, they should be authorized to make more corrections. The authorization period is generally five to seven months. After authorization, pay 295 yuan registration fee, annual fee and stamp duty, and you will get the patent certificate in about two and a half months.
