Patents according to the neo-Schumpeterian approach: an introductory discussion
This paper deals with the theoretical status of patents, taking the neo-shumpeterian
approach as a reference. Different characteristics of patents are analysed: i) informational
contents; ii) appropriability of innovation returns; iii) the complex trade-off between
the incentives for innovation or diffusion; iv) patent scope and its impact on second generation
innovations; v) barrier to entry. This analysis leads to an evaluation of patent laws
as different mix of these characteristics. Finally, the specificities of patent laws adapted to
less-developed countries are discussed.
