The difference between a trademark and a brand is:

1. A trademark is a legal concept, which is protected by the Trademark Law. Once registered, the obligee enjoys the exclusive right to use the trademark. And brand is an economic concept.

2. For enterprises, there are usually only a few brands, but trademarks can choose to register a series of trademarks.

3. The function of a trademark is to associate products with enterprises and serve as a logo. The brand is related to the overall image of the enterprise, but the relationship between trademark and brand is also very close. Enterprises usually register the brand as one of a series of trademarks.
