the exclusive use license of a registered trademark means that a trademark registrant signs an exclusive use license contract with a licensee, and licenses the registered trademark to only one licensee in an agreed period, region and manner. The trademark registrant may use the registered trademark according to the agreement, but may not license others to use the registered trademark separately. According to this licensing method, a trademark registrant and a licensee can use a registered trademark at the same time, compete in the market, and share the benefits generated by the goods using the registered trademark. In the case of infringement of the exclusive right to use a registered trademark, the licensee of the exclusive use license contract can bring a lawsuit to the people's court together with the trademark registrant, or bring a lawsuit on his own without the trademark registrant bringing a lawsuit, and investigate the civil liability of the trademark infringer.
