Trademarks can be words, patterns, sounds or their combinations. After registration, a trademark can only be used in this trademark category, that is, a registered trademark can only be used in food, and a registered trademark can only be used in electrical appliances.

Copyright is copyright. After the creation of a work, the author owns the copyright of the work and registers it as an important element. In China, copyright registration is only to determine the ownership of works, which is beneficial to use as favorable evidence in the event of copyright disputes in the later period.

Therefore, the trademark copyright application is generally aimed at the pattern trademark or the sound trademark, and the pattern and the sound trademark have strong originality, otherwise there is no need to apply for copyright again.
