Chinese public university patents during 2006-20: a comprehensive investigation and comparative study

Promoting growth in patent activity was an important stated goal of China's Medium- and Long-Term Plan for Science and Technology Development (2006-20), and it was a successful one. By the end of this ambitious blueprint, China had witnessed enormous growth in the number of granted patents, especially those granted to public universities. This vital role played by universities in technology innovation justifies further research on the role of academia with respect to the development of technology. However, most studies on patenting by Chinese universities are limited in terms of research scale and context, and patent performance is seldom investigated in great detail. This study first presents an overall analysis of the utility patents granted to Chinese public universities (not utility model patents). Then, we compare the patent performance of two elite university groups: Project 985 universities in China and member institutions of the Association of American Universities (AAU) in the USA. Our results show that Chinese universities account for a high proportion of the total patents granted in China, and the number of patents granted to universities has grown rapidly in recent decades, making them a very substantial contributor to China's innovation system. However, the value of patents did not improve as their counts surged. Compared to AAU universities, the technological and economic value of patents held by Project 985 universities is considerably lower, even for the top-patenting universities in China. These findings extend our understanding of technological innovation activity in China's academic landscape and might inspire future policies toward patent quality and impact.
