This paper aims to examine the impacts of competition law on the intellectual property (IP) abuse prevention in Australia, Japan and China. The author first examines the true nature of the IP abuse conduct in the Agreement on Trade-Related Aspects of IP Rights (TRIPS). He then provides a brief overview of the recent development of the Chinese Anti-Monopoly Law 2008 and its implementing regulations, particularly focusing on the provisions on IP abuse prevention. He further compares and critically examines how Japan and Australia deal with the interface of IP and competition laws, particularly examining the likely effects and potential limits of their laws on the IP abuse prevention issue. Finally, by drawing on lessons from the experiences of Japan and Australia, the author provides some practical suggestions for future law reforms in China and other countries in this challenging area.
