The service invention is one of the main forms of innovation activities. Using the method of descriptive statistical analysis and K‐means clustering analysis to analyze the dates of the application and the authorization of the service invention which is from 2002 to 2013 in SIPO ,we can draw the conclusions as follows. Analyzing the total aspect ,we can recognize that the amount of patents in the service invention increases fast ,and the average growth rate of the application is 36% ,and the authorization is 41%.However ,the ratio of patents in the service invention is low ,and the average application ratio is 36% ,and the average authorization ratio is 17%.Analyzing the applications ,the proportion both the application and the authorization is more than eighty percent of enterprises ,but the application structure must be changed. Analyzing the difference of areas ,the difference of the amount of the service invention is huge ,and it is related with the level of economic development. It is hope that the research re‐sults can provide a reference to the innovation of the service invention and improvement of the policy.%职务发明是创新活动的主要形式之一，论文利用EXCEL描述性统计分析方法与SPSS的K‐Means聚类分析方法，分析国家知识产权局2002—2013年职务发明专利申请量和授权量相关数据，结果表明：从总体上分析发明专利职务申请量与授权量增长迅速，平均增长率分别为36％和41％，发明专利职务量份额偏低，平均申请和平均授权比例仅为36％和17％。在申请主体方面，企业职务申请与授权比例占到八成以上，但其申请结构有待于优化。从地区差异分析，职务发明专利区域间的差异与当地经济发展水平相关。希冀这些研究结果为促进职务发明创新与政策完善提供参考依据。
