Pay attention to the examination of the licensee's qualification; 3. Pay attention to the maintenance of trademark rights; 4, strengthen the supervision of the licensee's trademark use.

Legal basis: Article 43 of the Trademark Law of People's Republic of China (PRC). A trademark registrant may authorize others to use its 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 its registered trademark, the licensor shall report the licensing of the trademark to the Trademark Office for the record, and the Trademark Office shall make an announcement. Without filing, the trademark license shall not be used against bona fide third parties.
