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 We investigate whether essential patents contribute to a “lock in” of outdated standards, or rather encourage investment and increase the pace of standardization.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.

基本专利和标准动态
本文考察了必要专利对标准化的影响。特别地,我们分析了专利对标准替换率的影响。我们调查关键专利是否有助于“锁定”过时的标准,或者鼓励投资并加快标准化的步伐。在ICT领域超过6000个不同标准和近20000个标准版本的综合数据集的基础上,我们证明了必要的专利,以减少早期阶段标准替换的可能性。这种效果在标准发布后的头三年发生。另一方面,重要专利的声明增加了版本替换的可能性。我们认为,这些版本升级并不需要替换标准组件。对版本的影响反映了企业对标准化投资的增加,而早期标准替换率的降低反映了专利对标准化的稳定作用。
