in this case, in addition to the licensor giving the licensee the right to use its registered trademark, the licensee can also enjoy the right to exclude the use of the third party. That is, the licensor may not give the same license to any third party, but the licensor reserves the right to use the same registered trademark. Exclusive license only excludes third parties from using the trademark in the territory. In the event of infringement of the exclusive right to use a registered trademark, the licensee of the exclusive use license contract may file a lawsuit with the trademark registrant, or file a lawsuit on his own without the trademark registrant's prosecution. Legal basis: Article 43 of the Trademark Law of the People's Republic of China authorizes others to use its registered trademark, and the licensor shall report its trademark license to the Trademark Office for the record, which shall make an announcement. A trademark license may not be used against a bona fide third party without filing.
