In this paper, we discuss the implications of the recent Intellectual Propriety Right (IPR) enforcement in the European Union (EU) as a potential factor affecting agrifood biotechnology industry stagnation. After presenting a theoretical framework justifying patents, we describe some controversial questions in the European patent protection related to: a) the distinction between discovery and invention and; b) the morality and ordre public exception to the patentability. Although we provide some evidence about the reduction in importance of agrifood activities compared to that of pharmaceutical areas of application, we conclude that differences between EU and other developed countries IPR legislations are not the principal regulatory controversial factor affecting activities in the agrifood biotechnology sector.
