In the era of rapid technological advancement, artificial intelligence (AI) has emerged as a transformative force across various domains. However, this widespread integration of AI technology has given rise to complex intellectual property challenges, particularly in the realm of copyright. This paper explores the intricate landscape of AI copyright issues, addressing disputes related to training data, the copyright status of AI entities, and ownership attribution for creative works generated by AI. From an object perspective, AI-generated creations undeniably meet the requirements of originality and merit copyright protection, irrespective of civil law or common law frameworks. However, from a subject perspective, the legal recognition of independent copyright status for AI is currently lacking in most jurisdictions. Consequently, it is argued that the relationship between AI and its human operator should be legally characterized as a tool-based association, essential for addressing ownership concerns regarding AI-generated works. Furthermore, AI gives rise to novel copyright infringement quandaries, such as data utilization and incorporation of copyrighted works, presenting challenges in definition and enforcement within existing legal frameworks. Thus, there is a pressing need to refine and enhance relevant laws to adequately address these emerging challenges. As AI technology continues to progress, the copyright conundrums associated with it are poised to evolve, necessitating profound and extensive discourse within the realms of law and intellectual property.
