UEMATSU on Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law

The latest issue of the Ritsumeikan Law Review (No. 43, 2025), a law review in English published by the Ritsumeikan University Law Association since 1986, features a study by Professor Mao UEMATSU (School of Law, Ritsumeikan University) entitled Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law.

The article examines a series of patent litigation cases in Korea and Japan, analyzing them to “illustrate the complexity of cross-border patent litigation.” It further argues that, even after reforms to procedural laws in both Korea and Japan, structurally similar cross-border conflicts remain unresolved. The paper concludes with preliminary reflections on possible improvements in legal coordination within Asia.

By introducing case law from both jurisdictions and sharing information on recent legal developments in the region, the study provides valuable material for comparative research and contributes to a better understanding of the dynamics of Asian private international law.
