 The value of Chinese patents: An empirical investigation of citation lagsChristian Fisch, Philipp Sandner and Lukas Regner China Economic Review, 2017, vol. 45, issue C, 22-34 Abstract: China has been experiencing a substantial growth in patent applications. But is this increase accompanied by a similar increase in patent value? To assess this question, we examine the citation lag of Chinese patents as a proxy of patent value in comparison with patents from the US, Europe, Japan, and Korea. Our empirical analysis comprises a unique data set of 60,000 patents with priority years between 2000 and 2010. Utilizing Cox regressions, our results show that Chinese patents suffer from a large citation lag in comparison to international patents, indicating a lower value. This is especially true for patents filed domestically. However, we find empirical support for an increasing patent value in more recent patents. China shows a strong dynamic in the field of patenting and our results suggest that the gap between Chinese patents and international patents might narrow down in the near future.
