Network Operators' Requirements and the Structure of Telecommunications Standards

This article uses citations to patents disclosed in the standard setting process to measure the technological significance of voluntary standard setting organizations (SSOs). We find that SSO patents are outliers in several dimensions and importantly, are cited far more frequently than a set of control patents. More surprisingly, we find that SSO patents receive citations for a much longer period of time. Furthermore, we find a significant correlation between citation and the disclosure of a patent to an SSO, which may imply a marginal impact of disclosure. These results provide the first empirical look at patents disclosed to SSO’s, and show that these organizations both select important technologies and play a role in establishing their significance.
