You must have obtained the notice of "utility model patent" from the Patent Office before paying the patent registration fee, stamp duty of 205 yuan and the annual fee of the first year in 90 yuan, right? If that's the case, since the Patent Office has issued a notice to grant a patent for utility model, and you have paid all the fees in the notice, the probability of obtaining the certificate is 100% on the premise that you have paid the appropriate fees.
The annual fee you pay for 90 yuan is the annual fee for the first year. If you want to continue to obtain the patent right (the protection period of utility model patent is 10 year), you need to pay the annual fee to the Patent Office every year, which is 1-3 years in 90 yuan, 4-5 years in 900 yuan, 6-8 years in 1200 yuan and 9-65438 years.
