The specific reasons for the termination of the patent right include:
1. The patentee fails to pay the annual fee as required.
2. The patentee waives his patent right in writing.
3. The invention patent, utility model patent and design patent of the party concerned have expired.
Patent, literally, refers to the exclusive right. The word patent comes from Latin Litteraepatentes, which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive rights certificate signed by the British king himself.
