If the patentee fails to pay the annual fee on time or the amount paid is insufficient after the year when the patent right was granted, the patent administration department of the State Council shall notify the patentee to pay the annual fee within 6 months from the date when the annual fee should be paid, and pay the late fee at the same time; The amount of the late payment fee is calculated by adding 5% of the full annual fee of the current year for every 1 month that exceeds the prescribed payment time; If it is not paid at the expiration of the time limit, the patent right shall be terminated from the date when the annual fee should be paid.
After the termination of the patent right, if someone else applies for a certificate, the patent right belongs to others. Hope to adopt
