Will the patent right be permanently suspended as long as the annual fee is not paid?

If you don't pay the annual fee, the patent right will be terminated. But it will not be terminated immediately, and there will be a payment deadline. That is, if the patentee fails to pay the annual fee within the time limit, the patent administration department in the State Council shall notify the patentee to pay the overdue fine within 6 months from the date when the annual fee should be paid, and at the same time pay the overdue fine. If the patentee fails to pay the overdue fine, the patent right shall be terminated from the date when the annual fee should be paid.
