A trademark is a brand and a commercial identification mark. Copyright is a work created by oneself. If a registered work is used as a trademark, it is still necessary to register a trademark, otherwise it will be infringing. The registration of copyright works is a formal examination, and the trademark is a substantive examination. Suggestion: For your original distinctive works, you should register the copyright and trademark at the same time. However, if the works are very similar to other people's works, that is, there are many similar graphics when inquiring about registered trademarks, then the originality of this graphic is relatively small, so even if you register the copyright in the future, it will be reasonably considered that you copied other people's works, and it will be very troublesome to defend rights. See Articles 9 and 32 of the Trademark Law and Articles 2 and 47.48 of the Copyright Law for details.
