ABSTRACT The current IP preliminary injunction system in China is an awkward mixture that has developed under two shadows: U.S.–China trade relations, and path dependence. This article traces the historical moments when China amended its rules on IP preliminary injunctions. It finds that, while U.S.–China trade relations facilitated the transplantation of equitable standards into the regime, the basic procedural framework, rooted in the civil law tradition, remains largely intact. These double shadows have introduced pressing problems into the system. However, most of these issues can be attributed to China's retention of its basic procedural framework, which is shared with and originates from the property preservation system. Path dependence theory aptly explains this developmental trajectory and offers normative guidance for future reforms. It may not be feasible to conduct a full cost–benefit analysis on establishing a standalone framework for IP preliminary injunctions in China, which would represent a radical alteration of the system. However, the developmental-evolution model of path dependence theory can still provide valuable insights, even if the system currently exhibits a semi-strong form of path dependence. Chinese legislators could design future incremental reforms with path evolution in mind, aiming for a gradual recombination that ultimately pulls the IP preliminary injunction system out of its original procedural framework. Once sufficient incremental reforms have accumulated, decision-makers can seize critical junctures (such as future escalations in U.S.–China trade conflicts) as opportunities to establish a new, standalone framework for IP preliminary injunctions, thereby breaking the lock-in loop.
