With the vigorous development of artificial intelligence (AI) technology, it has exerted a significant impact on the intellectual property (IP) system. AI poses unprecedented challenges to the definition of IP objects, the determination of right ownership, the manifestation of infringement forms, and the conduct of judicial adjudication. As a key pillar of the IP system, judicial protection is urgently required to address these challenges. This article will conduct an in-depth analysis of the copyright ownership of AI-generated content, the patent protection path for AI assisted inventions and creations, and the identification dilemma regarding the legality of AI training data, aiming to provide effective ideas for tackling these challenges.
