A well-known trademark is a trademark type officially recognized by the Trademark Office of the State Administration for Industry and Commerce of China, which is widely known to the public and enjoys a high reputation in China. The protection of well-known trademarks is not limited to the same or similar goods or services. When applying for registration or use of different or similar goods, they will not be registered and prohibited from being used. Therefore, well-known trademarks are given a wide range of exclusive rights.

Moreover, the company name and website domain name of the enterprise holding the "well-known trademark" will be specially protected by law, which is different from ordinary trademarks. So far, there are 1624 trademarks recognized as "well-known trademarks" in China, of which 98 are foreign brands.
