In this paper I discuss the fact that economists define optimal IP rights as a continuum of options in three dimensions: height, breadth and length. At the operational level we see the impossibility of multiplying rights indefinitely (due to prohibitive transaction costs), as well as the use of a limited number of IP tools which have led to the implementation of flexibilities. These flexibilities are designed to limit certain perverse effects of rights ill-adjusted to the characteristics of some economic sectors (agricultural biotechnologies, pharmacy, etc.). In this context, I analyse how these flexibilities are implemented in TRIPS and TRIPS+ agreements and I study the consequences for Developing Countries.
