Abstract
The relevant data of 3838 domestic patents and foreign patents, which were granted by SIPO in 1994, are comparatively analyzed using SPSS software, and fund that the maintenance rate, the maintenance time, the average number of claims and the examination time of domestic patents are significantly less than foreign patents. In the maintaining patents, foreign patents focus on high-tech fields; domestic patents focus on traditional technologies fields. From the perspective of the maintenance status of patents, the innovation ability of domestic patentee is less than that of foreign patentee.
