1. Well-known trademarks and ordinary trademarks have different meanings. Well-known trademarks are widely known to the relevant public and enjoy a high reputation in China. Ordinary trademarks, on the other hand, do not need to be widely known to the relevant public in China, nor do they need to enjoy a high reputation. 2. Ordinary trademarks with different recognition or acquisition methods are generally recognized by the Trademark Office, while well-known trademarks sometimes need the recognition of the Trademark Review and Adjudication Board or the judgment of the court. 3. For ordinary trademarks with different protections, the vast majority of trademarks that are not protected by special laws are normally used; Once a well-known trademark is recognized, it enjoys special legal protection. Ordinary trademarks can only be protected by law in the categories of goods or services approved for registration and enjoy the exclusive right to use trademarks; Well-known trademarks are protected in different degrees by their originality and distinctiveness. Well-known trademarks can resist the malicious registration of others; Other companies may not register the well-known trademark as a domain name; No other company may register the well-known trademark as the company name. The judicial protection of well-known trademarks can be divided into two levels: one is the protection in the registration stage, and the other is the protection in the trademark infringement stage after registration.
