Copyright registration will affect trademark registration. Copyright registration is beneficial to prevent the loss of rights caused by registering only one trademark. You can provide proof of protection of registered copyright in case of conflict with others' trademark rights, and you can also prevent infringement caused by others' trademarks being similar or similar to your own trademarks.

Legal basis:

Article 30 of the Trademark Law of People's Republic of China (PRC) If the trademark applied for registration does not conform to the relevant provisions of this Law or is identical with or similar to a trademark registered or preliminarily approved by others on the same kind of goods or similar goods, the Trademark Office will reject the application and will not make an announcement. Article 31 of the Trademark Law of People's Republic of China (PRC) * * * Where two or more applicants for trademark registration apply for registration with the same or similar trademarks on the same kind of goods or similar goods, they shall make a preliminary examination of the trademark applied earlier and make an announcement; Where an application is filed on the same day, the prior trademark shall be preliminarily examined and announced, and the application of others shall be rejected without announcement. Article 32 of the Trademark Law of People's Republic of China (PRC) * * * An application for trademark registration shall not damage the prior rights of others, nor shall it preempt the registration of a trademark that has been used by others and has certain influence by unfair means.
