Co-inventor Analysis on China's International Technology Collaboration in US Patent Activities: 1976-2010

Abstract

Since 1978, China's economy and science & technology boom and it has shown great power and immense potential to the world. This prosperity is inseparable from China's international collaboration. This paper is focused on China's international technology collaboration activities based on the USPTO patent data from 1976 to 2010. By using of patent statistics analysis and association analysis method, we analyze the US patent data on co-inventor level. The analysis showed that the number of joint patent got a leap and increasing at a high speed at the beginning of 1997. The cooperation scope is gradually expanded and the innovation capacity improved significantly. Most of the co-inventors are from the United States, Taiwan province, Hong Kong and Japan. In the areas of cooperation research field, the joint patents mainly distribute in G06, H01 and H05.
