Patent subsidy policy is an important policy tool for the government to encourage and guide the innovation subjects to apply for patent. This paper mainly adopts the Mann-Whitney U test to quantitatively analyze the impact of regional patent subsidy policy on patent application. It takes four provinces as the research objects. The result shows that patent subsidy policy of each region has different effects on different kinds of patent application, and thus some policy suggestions are proposed. In addition this paper presents the thinking and prospect for the applicability of Mann-Whitney U test in patent issues.
