How much is the annual fee for utility model patents?

The annual fee is different every year. I don't know what year yours is, so you have to hand it in.

The termination of patent rights can be divided into:

(1) Expiration: the patent right of utility model or design shall be maintained for 10 years from the date of application, and shall be terminated according to law;

(2) Termination without payment: If the patentee fails to pay the annual fee and overdue fine in full as required, the patent right shall be terminated from the expiration date of the previous year.
