Answer: The license contract shall not exceed the validity period of the trademark! Therefore, the maximum period for trademark authorization is ten years. What is trademark licensing? Trademark licensing refers to the act of a trademark registrant allowing others to use its registered trademark through legal procedures. Generally, the exclusive use period of the trademark shall not exceed 10 years. However, the trademark exclusive right can be renewed 6 months before the expiration, and each renewal period is 10 years. You can sign a trademark license contract again. As for the reason, it is because the trademark has a limit on the period of exclusive use. If the renewal is not carried out within the renewal period and the extension period, the exclusive right of the trademark will be lost.
