Abstract On 22 August 2025, the Intellectual Property Division of the Supreme People’s Court of China ruled for the first time that core algorithm elements for AI deep learning, such as training code and databases, qualify as trade secrets due to their secrecy, commercial value and confidentiality. The court found that the appellees had failed to prove independent development of the allegedly infringing technology and lacked sufficient evidence to rebut the presumption of secrecy, thereby infringing the appellant’s trade secret rights.
Quan et al. (Mon,) studied this question.
