This article analyzes China’s Data IP experiment based on the “Three Types Separation” rule from the 2022 Data Twenty Measures. Three parallel registration systems run by the China National Intellectual Property Administration, the National Data Administration and the Ministry of Finance regulate data IP, data property rights, and data assets respectively. Pilot results and Zhejiang surveys reveal domestic private enterprises dominate registrations, mostly for internal data product development. Courts treat Data IP certificates as preliminary evidence under the Anti-Unfair Competition Law. Despite booming registration volume, institutional coordination and immature data trading markets remain challenges for the system.
