Value of Chinese Patents: Evidence from the Chinese Patent Inventor Survey


How valuable are Chinese patents really? Critics have long argued that the value of Chinese patents is low given the variety of attractive government benefits accorded to those who apply for patents. Using the inventor survey approach (one of three major approaches used to estimate the value of patents), I attempt to uncover the value of Chinese patents. The data source for the study—the Chinese Patent Inventor Survey conducted by the China State Intellectual Property Office (SIPO)—is unique insofar as no academic research literature has hitherto made use of this data source (with the SIPO survey having been conducted since 2008) to estimate the value of Chinese patents. Using 145,597 enterprise- completed questionnaires from SIPO surveys conducted from 2008 through 2013, my estimates provide evidence relating to the debate on the impact of government subsidies on patenting activities in China.
