After copyright registration, you can have evidence to prove that the copyright belongs to you when there are some conflicts and disputes. So will copyright registration affect the registration of trademarks? Whether copyright registration will affect trademark registration does not. Although trademark rights and copyrights are both intellectual property rights, they are protected by different laws and have different objects. Registration as a trademark can exclude others from using the same or similar trademark on the same or similar goods, but it cannot exclude others from registering or using it on different or similar goods (although it is possible to object on the basis of copyright, but without registration, it will be difficult to evidence). The cost of registering and protecting all categories is relatively high. The best way is to apply for copyright registration, which will prevent others from registering it as a trademark. However, not all trademarks can apply for copyright registration.
