Abstract: This paper seeks to lay the groundwork for future research using citation data from patents issued by the China National Intellectual Property Administration (CNIPA). We comprehensively review the citation practices of CNIPA and build the first citation dataset from the documents of CNIPA-granted patents. Our dataset includes both examiner and applicant citations. Technical validation shows that the accuracy of our dataset is over 95 percent, making it reliable for academic studies. We find that the number of forward citations is significantly and positively associated with patent value. We also find applicant citations are stronger predictors of patent value. We provide recommendations for best practices using the CNIPA citation data and make the dataset publicly available for future research.
