A well-known trademark refers to a trademark widely known to the relevant public in China. Well-known trademarks are recognized on a case-by-case basis in China. If it is recognized as a well-known trademark when a trademark dispute occurs, it will not be protected as a well-known trademark in subsequent disputes. China's restrictions on well-known trademarks are that producers and operators are not allowed to use the words "well-known trademarks" in commodities, commodity packages or containers, or in commercial activities such as advertisements and exhibitions. In addition to the above restrictions, the use of well-known trademarks is the same as that of ordinary trademarks, but the protection of registered well-known trademarks is stronger than that of ordinary registered trademarks, which can achieve cross-class protection and prohibit others 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, and others can only be prohibited from using the same or similar trademarks on the same or similar goods.

the trademark law of the people's republic of china

Article 13

Trademark holders who are well-known to the relevant public think that their rights have been infringed may request the protection of the well-known trademark in accordance with the provisions of this Law.

A trademark applied for registration on the same or similar goods is a well-known trademark copied, imitated or translated by others, which is not registered in China. It is easy to cause confusion, so it is not registered and prohibited to be used.

Where a trademark applied for registration on different or dissimilar goods is a well-known trademark registered by others in China, misleading the public and possibly harming the interests of the registrant of the well-known trademark, it shall not be registered and its use shall be prohibited. Article 15

Without authorization, the agent or representative registers the trademark of the principal or the principal in his own name. If the principal or the principal has any objection, it shall not be registered and the use thereof shall be prohibited.

Where the trademark applied for registration on the same or similar goods is the same as or similar to the unregistered trademark previously used by others, and the applicant has a contract, business relationship or other relationship with others other than those specified in the preceding paragraph, knowing that the trademark of others exists, and others raise objections, registration shall not be granted.
