In recent years，brain-computer interface technology has shown rapid development，with various brain-computer interface-generated products continuously emerging. However，the copyright protection of these products faces practical challenges，specifically manifested as uncertainty about whether the products meet the standard as constituent elements of the work，unclear attribution of rights and interests，and difficulties in determining the standard for infringement. To safeguard the legitimate interests of creators and promote technological innovation and development，it is imperative to incorporate brain-computer interface products into the copyright protection system. Therefore，it is necessary to clarify its copyright eligibility，determine the ownership of authorship copyright，and strengthen the protection of privacy data related to the brain. These aim to alleviate the practical challenges of copyright protection and promote the steady advancement of brain - computer interface technology.
