The protection scope of well-known trademarks that are not registered in China is different from that of well-known trademarks registered in China. 1. The trademark applied for registration of 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. That is to say, for well-known trademarks that are not registered in China, only the right to use the same or similar goods or services is protected. The trademark applied for registration is a well-known trademark copied, imitated or translated by others and used on the same or similar goods or services. If it is easy to cause confusion, it shall not be registered and its use shall be prohibited. However, if the goods and services using the registered trademark are not the same or similar to those using the well-known trademark that is not registered in China, and it is not easy to cause confusion, the registration and use of the trademark will not be prohibited. Second, the trademarks applied for registration of different commodities or similar commodities are well-known trademarks registered by others in China, which mislead the public and may harm the interests of well-known trademark registrants, so they shall not be registered and prohibited from being used. That is to say, for well-known trademarks registered in China, not only others are forbidden to register and use the same or similar goods or services, but also others are forbidden to register and use different or dissimilar goods or services, which embodies the principle that China's trademark law focuses on protecting registered trademarks.
