Abstract: Digital innovation is typical patent-intensive innovation. In recent years, strategic patent behaviors have been increasingly emerging in the field of digital innovation. It has had a significantly negative impact on digital innovation. It is necessary to have an in-depth research on strategic patent behaviors in digital innovation. The analysis of time series data shows that the surge of patent families leads to the surge of patent quantity in this field. At the same time, patent litigations also present an explosive growth trend in digital innovation. On this basis, the research shows that patent families and patent litigations are not isolated in digital innovation. There is a significant interaction of mutual promotion between patent families and patent litigations. That is, the growth of patent family quantity leads to the emergence of massive patent litigations and the emergence of patent litigations stimulates more applications of patent families. Therefore, it is necessary to improve the examination and authorization standard of patent families. We can achieve the policy effect of "killing two birds with one stone" and curb the negative impact of the overflow of strategic patent behaviors on digital innovation.

摘要： 数字创新是典型的专利密集型创新，近年来，该领域的策略性专利行为日益凸现，对数字创新产生了不容忽视的负面影响，有必要深入研究数字创新的策略性专利行为。针对时间序列数据的分析表明，同族专利导致了该领域专利数量激增；同时，专利诉讼也呈现爆发式增长态势；在此基础上的研究表明，数字创新领域的同族专利与专利诉讼不是孤立的，二者存在显著的相互促进作用，即同族专利的增长引发专利诉讼的涌现，而专利诉讼的涌现刺激布局更多的同族专利。因此，有必要提高同族专利审查授权标准，以达到“一石二鸟”的效果，遏制策略性专利行为泛滥对数字创新的负面影响。
