France has been a political and economic power in the world for centuries, and the founding country of the modern civil law system and the pioneer in the construction of the patent system. Due to its unique historical views of the legislators of the past on natural human rights and the separation of powers, France realizes a unitary system for trial by ordinary courts in patent litigation procedures, and deliberately reduce the involvement of administrative power in patent affairs, making the overall remedy process lighter and creating a significant cost advantage in litigation.However, patent rights cannot be fully explained in terms of“public law theory”or“private law theory”on the basis of its inherent nature. Because patents are the intervention of state actions (public law) at the application and examination stage, but have the value of property law (private law) at the stage of obtaining patent rights. It should be remedied through corresponding litigation procedures (ie administrative litigation or civil litigation). This is also a problem for the dual system of patent litigation adopted by Taiwan. Though the effectiveness of the Intellectual Property Case Trial Law in 2008 has initially solved the problem of the dual system of litigation and improved courts delay, it cannot completely solve the structural problems of the dual system.It is interesting that France, as the founding country of the dual litigation system, has realized a completely unitary system in the field of patent litigation. This article first explains the theoretical formation of the French patent litigation unitary system, then discusses the litigation practice of the French patent litigation unitary system and its characteristics and advantages. Through the method of comparative law, this article puts forward relevant views and suggestions regarding the current patent litigation system in Taiwan and the“Draft Amendments to Some Provisions of the Patent Law (Second Draft)”which was published by the Intellectual Property Office in June 2021.
