Well-known trademarks, famous trademarks and well-known trademarks are "famous trademarks". There are many similarities and significant differences between the three, which are mainly reflected in the following aspects:

First, the recognition agencies are different: Well-known trademarks are recognized by the Trademark Office of the State Administration for Industry and Commerce or the People's Court according to judicial procedures, famous trademarks are recognized by the provincial industrial and commercial departments, and well-known trademarks are generally recognized by the local (city) industrial and commercial departments.

The second is that the recognition standards are different: a well-known trademark must be known to the relevant public across the country, while a famous trademark and a well-known trademark must be known to at least the relevant public in the province or local (city).

Third, the requirements for trademark registration are different: a well-known trademark may be a registered trademark or an unregistered trademark, while a famous trademark and a well-known trademark must be a registered trademark.

At the same time, the three can also be transformed into each other, because the reputation and popularity of each trademark continue to change with the passage of time or changes in the use of trademark users. Well-known trademarks are famous trademarks. It can gradually evolve into a well-known trademark, and a well-known trademark may also dilute into a famous trademark or even an ordinary trademark.
