This paper provides the systematic literature review of the literature on patent law failure. Specifically, we focus on both theoretical and empirical studies on patent law, its framework and evolution of its failure. We also explain the influence of TRIPS agreement on developing countries. Additionally, this paper also provides a broader overview of patent law in various settings. Further, to provide a broader framework and future aspects of the patent law in developing countries we tried to mostly mention and interpret the data in relation to the development of those countries. The article also covers different reasons of patent law failure.
