The paper presents an analysis of technology dependency networks between large companies in the IT, telecoms equipment and electronics sectors using patent citations. We then study the impact on start-ups seeking to penetrate these markets. This study highlights the ambivalent nature of patents used as a bargaining chip: they become a tool for cooperation, but this function leads to the exclusion of companies that have nothing to offer in return for access to technology exchange networks.
