The purpose of this paper is to examine the interrelationship between intellectual property rights (IPR) and competition policy. Specifically, issues related to new developments on technological protection measures and digital rights management on copyrights law and its relationship to competition policy are illustrated. The new trend of the legislative directions and frameworks in some advanced countries are presented. Some of the well-known legal cases in the related issues are demonstrated as examples for further discussion. Finally, the balancing needs between IPR and competition policy are stressed so as to pursue the public interests and social justice, which should be the ultimate direction that related legislations aim to.
