In all spheres of knowledge there are aspects of great relevance that justify their particular treatment. In the field of Mexican Public Law there could be no exception. On this occasion we have selected three legal institutions that deserve a scrupulous examination that allows not only to understand them but also to generate innovative knowledge through research such as the one developed in this work. The aim is to address specificities around the theory of unforeseeability focused on public procurement with a terminal orientation to the intellectual property regime. It also studies the historical and normative assumptions that have been necessary for the effective protection of intellectual property rights in Mexico. Finally, a peculiar treatment will be given to the figure of the hung jury with the idea of assessing whether there are conditions to be introduced in the Mexican criminal justice system.
