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 results can provide a reference to the innovation of the service invention and improvement of the policy.
