Abstract
Compared with the numbers of patent applications and patent granted, the numbers of valid patents and their maintenance times can better embody one country’s technological innovation capability. In this book, 2921 patents, which granted by the State Intellectual Property Office in China in 1994 and up to April 30, 2007 terminated due to unpaid fees, are analyzed based on the patent information perspective by multivariate linear regression using SPSS software (11.5). The results show that the average maintenance time of patents, which granted by the State Intellectual Property Office, is shorter and the terminated speed quicker. The effecting degrees of a nationality of applicants, a examination time, a types of patentees, a number of inventors and a claims number of patents on the paten maintenance time followed by weakening.

In China, patent includes invention patent, utility models patent and design patent. Because utility models patent and design patent need not substantive examination, so many scholars at home and abroad believe the quantity of inventions patents is one of indicators to measure the innovation capability of enterprises, a region and a nation. Therefore, in this book “patent” just refers to invention patent.

There is only 1 patent terminated by the declaration of abandonment, while 2921 were terminated for failure to pay maintenance fees. So the terminated patents mentioned hereinafter should mean the patents terminated for failure to pay maintenance fees unless there is a specific explanation, and the maintenance time of patents means the period from grant to termination for failure to pay maintenance fees.
