Indices are central for comparing the strength of patent systems across countries in international business research, intellectual property management and policymaking. However, existing approaches rely on book laws while most variance across countries emerges from enforcement. We address this weakness and present the Patent Enforcement Index which tracks differences in patent enforcement for 51 countries between 1998 and 2017. We utilize novel firm-level enforcement data and extend the conceptual framework of the patent systems strength index provided by Papageorgiadis et al. (2014). The new index reveals previously uncaptured volatility in patent enforcement and can be decomposed into three topical sub-indices.

指标是比较各国专利体系在国际商业研究，知识产权管理和政策制定方面的优势的关键。但是，现有方法依赖于图书法，而各国之间的大多数差异则来自执法。我们解决了这一弱点，并提出了专利执行指数（Patent Enforcement Index），该指数追踪了1998年至2017年间51个国家在专利执行方面的差异。我们利用新颖的公司级执法数据，并扩展了Papageorgiadis等人提供的专利制度实力指数的概念框架。（2014）。新索引揭示了专利执行中以前未捕获的波动性，可以分解为三个主题子索引。
