Trademark authorization, also known as trademark license, means that a trademark registrant authorizes others to use its registered trademark by signing a trademark authorization contract. Licensee engages in business activities (usually producing and selling a product or providing a service) according to the contract, and pays the corresponding fee-royalties to Licensor; At the same time, Licensor provides guidance and assistance in personnel training, organizational design and operation management. The Trademark Law stipulates that 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. The advantage of obtaining trademark authorization is that the licensee can obtain the right to use the trademark through special trademark authorization. With the popularity, good image and business philosophy of trademarks, we can make our products enter and be accepted by the market at lower cost, faster speed and lower risk, and make enterprises and products succeed quickly. Sales authorization generally refers to authorizing a product or service to an authorized person to operate sales. Article 43 of the Trademark Law of People's Republic of China (PRC)
