This article aims to propose a classification of Brazilian regions according to their technological skills. These are identified by technological classes, according to the International Patent Classification -IPC stemming from BADEPI/INPI for the period 2000-2011. The classification is based on three indicators: Zipf, Gini and Moran’s I (global and local) coefficients. Results indicate that the degree of hierarchy and concentration in Brazilian regions are smaller in technologies of chemistry food, mechanical and civil engineering, as such technologies are also present in less central regions. In contrast, technologies of electrical engineering and telecommunications, biological and nanotechnologies present a greater degree of hierarchy and concentration, mainly located in São Paulo, Campinas and Rio de Janeiro. Clustering patterns indicate the existence of positive spatial association of these technologies in the Southeast and South regions of Brazil, particularly in the state capitals and Campinas region.
