Territoriality and Intellectual Property Infringement Proceedings

Abstract This article examines the principle of territoriality in intellectual property rights ( IPR s) and its implications for cross-border infringement proceedings. It highlights the complexities arising from globalization and digital technologies, which challenge the traditional territorial nature of IPR s. The article compares jurisdictional approaches in the United States, the European Union, Korea, noting the strict adherence to territoriality in validity disputes and the varied stances on infringement claims. It also explores the innovative measures adopted by national courts, particularly in the context of Standard Essential Patents ( SEP s), to extend their jurisdiction while respecting territorial limits. The article underscores China’s pragmatic approach, balancing respect for territoriality with judicial efficiency, and its proactive role in setting global FRAND terms for SEP s. The analysis suggests that while territoriality remains a fundamental principle, evolving judicial practices are adapting to the demands of a globalized economy.
