Abstract

This paper examines the impact of essential patents on standardization. In particular, we analyze the influence of patents on the rate of standard replacement. We investigate whether essential patents contribute to a "lock in" of outdated standards, or rather encourage investment and increase the pace of standardization. Building upon a comprehensive dataset of over 6.000 different standards and nearly 20.000 standard versions in the field of ICT, we evidence essential patents to reduce the likelihood of standard replacement in early stages. This effect takes place in the first three years after the standard is issued. On the other hand, declarations of essential patents increase the likelihood of version replacement. We argue that these version upgrades do not entail replacement of standard components. The effect on versions reflects an increase in the firms' investment in standardization, while the reduced rate of standard replacement in early years reflects a stabilizing effect of patents on standardization.
