Legal analysis: No need. Because the design of graphic trademarks needs creative intellectual labor, when it reaches a certain creative height, graphic trademarks can become works in the sense of copyright law. At this point, the original author can register the copyright of the graphic trademark to prevent others from stealing it. This is voluntary registration.

Legal basis: Article 4 of the Copyright Law of People's Republic of China (PRC). When exercising copyright, the copyright owner shall not violate the Constitution and laws, and shall not harm the public interests. The state shall supervise and administer the publication and dissemination of works according to law.
