Advances in Patent Rights Acquisition in International Patent Law

The article examines the significant developments in international patent law over the past century, focusing on how procedural changes facilitated by treaties like the Paris Convention and the Patent Cooperation Treaty (PCT) have led to substantive shifts in domestic patent laws. It argues that while these procedural streamlinings aim to enhance efficiency, they have also influenced substantive legal changes, such as the U.S. transition from a first-to-invent to a first-to-file patent system. The author highlights the need to recognize how procedural harmonization can shape substantive patent law and policy.
