Trademark licensing contracts must be filed. The trademark licensing contract signed by both parties shall be reported to the Trademark Office for the record, so as to be consulted by a third party and play the role of publicity. If a trademark licensing contract is not submitted for filing and filing, the rights obtained by the licensee of the contract cannot be against a third party. Legal objectivity:

Article 43 of the Trademark Law A trademark registrant may authorize others to use his registered trademark by signing a trademark license contract. The licensor shall supervise the quality of the goods in which the licensee uses its registered trademark. The licensee shall guarantee the quality of the goods using the registered trademark. Where a registered trademark of another person is used with permission, the name of the licensee and the place of origin of the goods must be marked on the goods using the registered trademark. Where another person is licensed to use his registered trademark, the licensor shall report his trademark license to the Trademark Office for the record and the Trademark Office shall make an announcement. A trademark license may not be used against a bona fide third party without filing.
