Legal analysis: The termination of the trademark authorization letter is automatically terminated upon expiration of the authorization period, and if the trademark registrant and the licensed user reach an agreement through negotiation, the authorization license can be terminated in advance. Or if one party commits breach of contract or illegal behavior such as failing to perform the contract as agreed, the other party may exercise the right to terminate the contract in accordance with the law and terminate the authorization. If you want to terminate a trademark use contract, you must obtain the unanimous consent of both parties who signed the contract. If you unilaterally terminate the contract agreement, the other party can directly sue. This is considered a breach of contract and requires a certain amount of compensation and financial compensation to the other party.
