产业特性与专利联盟经济效率

由互补性专利形成的专利联盟能够克服“专利丛林”问题、提高纵向产业链经济效率，这一结论是对专利联盟的一般共识。以生物技术产业为例，从产业特性角度，分析在存在溢出效应和产品差异化的情况下，由互补性专利组成的专利联盟经济效率问题。研究发现，当专利联盟的形成导致溢出效应很大且最终产品近似可替代时，由互补性专利组成的专利联盟会降低社会总福利水平，这为专利联盟的反垄断规制审查提供了一种新的理论见解。

Industrial Characteristics and Economic Efficiency of Patent Pools

It is a general consensus that patent pools made up of complementary patents can overcome patent thicket problem and improve economic efficiency in vertical industrial chain. In this paper, from the perspective of industrial characteristics based on the biotechnology industry, it analyzes a complementary patent pool is whether efficiency-improving or not when spillover effects and differentiation are in the case. The conclusion is that when the formation of a patent pool leads to a large spillover effect and the final products are almost substitutable, even a complementary patent pool could reduce the level of social welfare. The result offers a new theoretical insight for antitrust review on patent pools.
