At present, brain-computer interface technology is developing rapidly, and brain-computer interface products are constantly emerging. However, the copyright protection of brain-computer interface products is facing practical difficulties, mainly reflected in the doubt of whether the products constitute works, the ambiguity of the rights and interests of the products, and the challenges in determining the infringement of the products. To protect the rights and interests of people with disabilities, safeguard the legitimate rights and interests of authors, and encourage innovation and technological development, it is necessary to include the products of brain-computer interfaces in copyright protection. Based on this, it is necessary to clarify the copyright of the products of brain-computer interfaces, define the copyright ownership of the products of brain-computer interfaces, and strengthen the protection of brain privacy data, so as to alleviate the practical predicament of copyright protection of the products of brain-computer interfaces and promote the development of brain-computer interface technology.
