The research studies on the patents which Chinese Intellectual Property Office authorized between 1985 and 2004, using LOGISTIC regression model to determine the influencing factors of patent maintenance. The results demonstrate that the maintenance quantity of Chinese patents first rises then drops over time. After reaching its peak at the point of the third year, the duration obeys exponential-like distribution. The type of patent applicants, the nationality of patent applicants, authorization year, the number of applicants, and page number of the application influence patent maintenance in a successively decreasing way. The extension of patent maintenance should be promoted from different perspectives, which include enhancing local patent quality and facilitating the industrialization of patents applied by universities and research institutions.
Key words: patent value; patent maintenance; influence factors; patent quality
