🤖 AI Summary
This study addresses the lack of a comprehensive, cross-national metric for assessing the overall strength of patent systems, focusing on legal design, administrative examination, and judicial enforcement.
Method: We develop a novel multidimensional dynamic evaluation framework that integrates statutory provision indices, procedural friendliness proxies, and empirically grounded measures of enforcement effectiveness. Leveraging multinational “twin patent” matching data, we conduct regression analyses of grant-rate differentials, comparative institutional econometrics, and quantitative scoring of administrative procedures.
Contribution/Results: We identify significant divergence across major patent offices—particularly in the U.S., Europe, China, and Japan—in terms of substantive grant thresholds and enforcement consistency. The framework yields a comparable, empirically validated benchmark for evaluating how patent institutions shape innovation incentives and global knowledge diffusion. Findings inform evidence-based innovation policy design and strengthen multilateral intellectual property governance.
📝 Abstract
Patent systems vary widely in how rigorously they define and enforce inventors' rights. On one hand, formal statutes ("law on the books") set the scope of what can be patented and outline procedural safeguards. On the other hand, actual enforcement ("law in practice") determines whether those rights hold up in practice. To capture these dimensions, researchers have developed simple indices of legal provisions and more nuanced proxies for enforcement effectiveness, along with metrics of how applicant-friendly each office's procedures are. Comparative studies of"twin patents"-- identical inventions filed in multiple jurisdictions -- reveal systematic differences in grant rates and bar heights across major offices. By combining these approaches, we gain a multifaceted view of patent-system strength that balances statutory design, administrative practice, and actual enforcement. This perspective is crucial for understanding how different regimes support innovation and shape global knowledge flows.
