Bifurcation – Separation of Infringement and Validity


Korea has bifurcated system that allocates decision power to separate authorities. Patent Infringement Issue and Patent Invalidity Issue must be decided by two separate and independent courts as shown below. Patent infringement and invalidity challenge may occur simultaneously but two proceedings are correlated. Invalidity defense is allowed in limited circumstances under patent Infringement lawsuits. A court may stay the infringement lawsuit proceeding on its discretion due to Invalidity proceeding.
