Legal analysis: If two trademarks have the same characteristics and ordinary buyers can't distinguish them with ordinary attention, they are similar trademarks. General buyers include the ultimate consumer middlemen, but not connoisseurs with special interests. If some well-known trademarks or well-known trademarks have high public awareness and strong indication function for the source of goods or services, then it is necessary to determine whether the two trademarks are similar.

Legal basis: Article 13 of the Trademark Law of People's Republic of China (PRC) is a trademark well known to the relevant public. If the obligee thinks that his rights have been infringed, he may request the protection of well-known trademarks 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.
