Chorzów Factory – intellectual property and the continuity of international law in investor-state dispute settlement

One of the most important cases in the jurisprudence of international law – Chorzów Factory – has a hidden secret, so much so that, even when in plain sight, legal post-mortems of the case fail to mention this well-kept secret. Chorzów Factory was about intellectual property rights, specifically patents and trade secrets, and this narrative has never been fully addressed. When the developments in international investment law and arbitration are fully considered it is worth looking back at Chorzów Factory to associate it with new streams of contemporary investor-state disputes that include issues such as intellectual property rights. Because Chorzów Factory has established the full reparation standard for unlawful expropriation, the standard has enabled a continuity of international law and underscores its importance for contemporary investment arbitration. However, the intellectual property narrative of Chorzów Factory has been neglected, and, in this article, I want to develop the intellectual property narrative of Chorzów Factory and to demonstrate the nexus between fair compensation, intellectual property rights and the continuity of international law.
