The termination of trademark rights means that the registered trademark owner loses his trademark rights due to statutory reasons and is no longer protected by the law. Termination is divided into two categories: termination at the expiration of the term and early termination. When a registered trademark expires and is not renewed, the registered trademark will be canceled and the trademark rights will be terminated. Early termination generally includes four situations: First, the trademark owner declares to the Trademark Office that it has given up registration. For example, when there is a conflict with prior rights, the registration may be voluntarily abandoned. Generally speaking, if a trademark owner has entered into a trademark licensing contract with others, it cannot abandon the registration without the consent of the licensee, otherwise it will be liable for breach of contract. Second, the Trademark Review and Adjudication Board ruled that the grounds for the dispute were established and revoked the registered trademark. Third, the Trademark Office rules or the People's Court declares the registered trademark to be invalid. The declaration of invalidity has retroactive effect, that is, the trademark right is deemed to have ceased to exist from the beginning.
