Brand and trademark are two similar concepts. They have the same connection but also have certain differences.

Contact:

1. Both are the logos of a company or a product or service.

2. Both have a formulating effect on specific products or services.

3. Both can replace products or services in social publicity to a certain extent and within a certain range.

4. Both appear in the form of certain words, numbers, letters, graphics, etc.

Difference:

1. Trademarks need to be registered through legal procedures before they can have legal effect, but brands do not.

2. A trademark can be a picture or text that has nothing to do with the product or company name, while a brand is usually the text in the company name, or is specifically related to the product.

3. Through publicity and marketing, a trademark can become the brand of a specific company or product or service. A brand does not necessarily refer to a company's trademark.
