Do I have to pay the patent fee every year?

Patent fees should be paid every year, and patent fees 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.
