Comparative Perspectives on Specialised Intellectual Property Courts: Understanding Japan's Intellectual Property High Court Through the Lens of the US Federal Circuit

Abstract This article develops a comparative analysis of specialised courts in intellectual property across both Japan and the US. This article considers the IPHC through the lens of the CAFC to investigate the differing institutional impact and illuminate the most pressing issues in Japanese patent law that have emerged as a result of transplanting this specialised court. Rather than a more conventional analysis of the implementation of these institutions, this article focuses instead on a comparative investigation of the soft law elements that have significantly influenced their effectiveness, providing a different insight on the relationship between these institutions and their broader contextual impact. The main findings of the comparative analysis are found in two primary areas – the impact of specialised courts on the consistency and reliability of patent law; and secondly, recommendations regarding the potential reform of Japanese patent law as it relates to the role of the IPHC. In terms of reform, this article analyzes the double-track problem in Japanese patent law and the key role that, with some modification to the court/patent office relationship, the IPHC could play in addressing this issue with a more fundamental realignment of patent law with its Continental history.
