Abstract: This article studies the inventive activity related to electric vehicles. Particularly, examining the relationship between the overlapping patents and a diverse population of agents: Companies, non-practicing entities, individual inventors and alliances. Based on information from the United States Patent and Trademark Office (USPTO), period from 1976 to 2012, it is presented: 1) as from network analysis, the increasing complexity of inventive electric vehicles; 2) the characteristics and evolution of inventive activity and, 3) its relationship with the existence of overlapping patents. It is shown that the evolution of overlapping patents (from low to high complexity) is associated with greater complexity of technological knowledge as well as greater diversity of agents.
