Abstract: This research aims to analyze the collaboration networks associated with the processes of invention and patenting in Latin American countries between 1970 and 2017. To do so, we apply social network analysis techniques to a rich database containing information from patents developed by Latin American inventors and registered in the USPTO during such period. We build and analyze three types of collaboration networks: networks of inventors, networks of innovators (i.e. patent owners) and networks of countries in the region. The study of the structural properties and the evolution of such networks allow us to present unprecedented empirical evidence on the forms of interaction and collaboration to invent in Latin America. This evidence shows that collaboration networks in Latin America are highly fragmented and disconnected. Moreover, networks are notoriously foreign-oriented, i.e. the linkages with external nodes are critical compared to the low presence of local connections. Major differences among the countries of the region can be observed, which allow us to identify different behaviors according to how much they use the patent system and the relative development of the national networks. In a region which has been historically characterized by high heterogeneity, this research allows recognizing specific patterns of innovation at the national level. In sum, the contributions of the paper are three fold. First, it presents novel empirical findings with unique information on interaction patterns at the Latin American level. Second, it allows analyzing the whole region and the main trends in the light of the large research background on invention and development from this region. Finally, it discusses some stylized facts in national cases, with the aim of encouraging new research questions for further research agenda.
