Abstract: In recent years, the rapid development of artificial intelligence technology has made intellectual property issues the focus of academic research and judicial decisions. This paper reviews the relevant literature and judicial precedents at home and abroad, focusing on the future development of artificial intelligence technology. From the perspective of stimulating innovation, this study has investigated the basic issues such as the subject qualification, object scope, acquisition standards, rights attribution, implementation and application, and effective regulation of intellectual property protection for works, signs and inventions created by artificial intelligence.It constructs a system of intellectual property protection for artificial intelligence and proposes countermeasures for building an intellectual property protection system for AI-generated works, signs, and inventions.The legal policies regarding intellectual property rights of artificial intelligence should be ly revised and improved. It should be clearly stipulated that works, signs and inventions generated by artificial intelligence can obtain intellectual property protection. The ownership of intellectual property rights of artificial intelligence-generated works, signs and inventions should follow the principle of contract. The qualification of artificial intelligence as the creator of works, the designer of signs and the inventor should be granted. The acquisition standards for intellectual property rights of artificial intelligence-generated works, signs and inventions should be improved. The application of the principles of good faith and creditworthiness, balance of interests and anti-abuse regulations of intellectual property rights should be strengthened in the field of artificial intelligence.
