Trademark registration [1] is the prerequisite and condition for a trademark user to obtain the exclusive right to use a trademark. Only trademarks that have been approved and registered are protected by law. The principles of trademark registration are the basic criteria for determining the exclusive right to use trademarks. The choice of different registration principles is the result of the legislators of various countries weighing the relationship between legal certainty and legal fairness in this issue. Trademark registration refers to the legal fact that in order to obtain the exclusive right to use a trademark, the trademark owner applies to the Trademark Office for registration of the trademark he uses in accordance with the registration conditions, principles and procedures stipulated by the state, and the Trademark Office approves the registration after review. A trademark that has been reviewed and registered by the Trademark Office is a registered trademark and enjoys the exclusive right to use the trademark. Simply put, a trademark is the brand of a commodity, a mark used by commodity producers and operators to distinguish the goods they produce or operate from those produced or operated by other commodity producers or operators.

This kind of mark usually consists of a combination of text, graphic English, and numbers. Trademarks protect trademark registrants by ensuring that they have the exclusive right to identify goods or services, or to license others to use them for remuneration. Many electronic brand trademarks are word trademarks; the Mercedes-Benz trademark (a triangle coated with a circle) is a graphic trademark; the Phoenix Bicycle Factory's "Phoenix" trademark is a combination of the word "Phoenix" and the graphic of the Phoenix bird, that is, It is a combination of words and graphics. Trademark registration means that the trademark user submits a registration application to the national trademark authority (Trademark Office of the State Administration for Industry and Commerce) in accordance with the conditions and procedures prescribed by law [1]. The national trademark authority examines and approves the legal facts of registration. In China, trademark registration is the prerequisite for legal protection of a trademark and the legal basis for determining the exclusive right to use a trademark. Once the trademark user is approved for trademark registration, it means that it has obtained the trademark. The exclusive right of this trademark is protected by law.
