China's well-known trademarks refer to trademarks that have been recognized as "well-known trademarks" by the competent authorities (Trademark Office of the State Administration for Industry and Commerce, the Trademark Review and Adjudication Board or the People's Court) in accordance with legal procedures. Well-known trademarks refer to trademarks that are widely known to the relevant public in China. my country's "Trademark Law" imposes restrictions on well-known trademarks: producers and operators shall not use the words "well-known trademark" on goods, product packaging or containers, or in advertising, exhibitions, or other commercial activities. In addition to the above restrictions, the use of well-known trademarks is the same as ordinary trademarks, but the protection of registered well-known trademarks is stronger than that of ordinary registered trademarks. Cross-class protection can be achieved, and others can be prohibited from using the same or similar trademarks in all categories. The protection of unregistered well-known trademarks is the same as that of ordinary registered trademarks. Others can only be prohibited from using the same or similar trademarks on the same or similar goods.
