The annual fee for utility model patents is fixed. When paying the annual fee for the first time, the patent office will give the payment instruction, which will be written clearly. The general annual fee of the utility model is: 1-3 years: 90 yuan; 4-5 years: 900 yuan; 6-8 years: 1200 yuan; 9- 10 year: 2,000 yuan.
If you pay by bank, you should indicate the name of the fee and your own patent number, otherwise the Patent Office will think that the fee is unknown.
I hope the answer will help you.
