The difference between a trademark and a logo 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. Logo usually refers to brand, which is an economic concept.

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

3. The function of a trademark is to associate the product with the enterprise and serve as an identifier. The logo is related to the overall image of the company.

But the relationship between trademarks and logos is also very close. Companies usually register their logos as one of a series of trademarks. In fact, it has been proven that registering a logo as a trademark and protecting it with trademark law is the most convenient, effective and powerful way to protect a company's goodwill. Therefore, in a sense, a company's logo and trademark can be the same, which is why people often equate logo and trademark. In fact, logo is broader in extension than trademark.

Legal basis: Article 11 of the "Trademark Law of the People's Republic of China" The following signs shall not be registered as trademarks:
