Legal analysis: useful. From the perspective of intellectual property protection, it is necessary to apply for registration of trademarks in copyright registration, especially those related to content. China's Trademark Law stipulates that if someone uses your work for trademark registration, they can raise an objection to the Trademark Office. In the case of sufficient conditions, it is recommended to apply for registration of the trademark and conduct copyright registration at the same time.

legal basis: article 3 of the trademark law of the people's Republic of China is a registered trademark, and the trademark registrant enjoys the exclusive right to use the trademark and is protected by law.
