Generative artificial intelligence products refer to "works" generated with the participation and assistance of generative artificial intelligence, which have different characteristics from traditional works. In today’s rapidly developing technology, there are increasingly more copyright disputes related to generative artificial intelligence, making it a hot topic of concern in the legal community. The paper analyzes typical cases and finds that courts in various regions have not yet formed a unified judgment approach on key issues such as copyrightability, copyright ownership, and infringement liability determination of generative artificial intelligence products. Through legal analysis of these key issues, the paper proposes to construct a specialized system for copyright protection and risk prevention of generative artificial intelligence products in accordance with the basic principles of the copyright system, thus achieving a balance of interests among multiple parties.
