Legal analysis: the criterion of trademark infringement is that the actor uses the same or similar trademark on the same kind of goods or similar goods without the permission of the trademark registrant, which is regarded as trademark infringement. According to the law, if an unregistered trademark is regarded as a registered trademark, the local administrative department for industry and commerce shall stop it, make corrections within a time limit and notify it.

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.
