Trademark is a symbol used by commodity producers, operators or service providers to help consumers identify brands and distinguish different places of origin. It is usually composed of visible elements such as text, graphics, letters, numbers, three-dimensional signs or colors. Brand is the customer's comprehensive cognition of enterprise sensibility and rationality, including product, name, price, quality, service, customer loyalty, popularity and satisfaction. Trademark embodies the concept of enterprise through visual communication art. An excellent trademark can let customers know about the enterprise and its connotation, and also become an important tool to show brand personality. On most occasions, people are used to calling trademarks "brands" or "brands". In fact, trademarks and brands are both related and different, and they are not exactly the same. Trademark is a legal concept and is protected by national laws. As a non-legal concept, brand is more related to business operation and operation. In order to obtain legal protection, brands must apply for trademark registration.
