(1) Prove that a trademark is a trademark of goods or services first. Compared with ordinary trademarks, certification trademarks have many differences: certification trademarks indicate that goods or services have a certain quality, while ordinary trademarks indicate that goods or services come from a certain operator; Prove that the trademark registrant must have the ability to detect and supervise goods or services, and the ordinary trademark registrant only needs to be a legally registered operator; Certification trademarks need to submit management rules when applying, but ordinary trademarks don't; The registrant of the certification trademark cannot use the certification trademark, and the registrant is free to use the registered trademark except for legal reasons.

(2) The registrant of a certification trademark must have the ability to detect and supervise goods or services. Judging from the registration and use of certification marks, the main responsibility of the registrant of certification marks is to manage certification marks, which is divided into two aspects: one is to manage the quality of goods or services, and the other is to supervise users to use certification marks.

(3) When the registrant of the certification trademark cannot use the certification trademark itself and requires the user's goods or services to meet the requirements for using the certification trademark, the registrant of the certification trademark shall not refuse to use it.

(4) The main function of a certification trademark is to prove, that is, to prove the origin, raw materials, accuracy, manufacturing method, quality or other specific qualities of a commodity or service.

Legal basis: Article 3 of the Trademark Law of People's Republic of China (PRC) is a registered trademark, including commodity trademark, service trademark, collective trademark and certification trademark; Trademark registrants enjoy the exclusive right to use trademarks and are protected by law.
