Abstract
We explored the interactions between papers and patents by studying cross-citations between journal papers and technical patents concerning CRISPR/CAS9, an emerging research topic. We found that the knowledge flow from patents to papers was weaker than that from papers to patents, while the knowledge flow of papers–papers and patents–patents were faster than that between papers and patents. From 2013 to 2017, the science cycle time (SCT) value of journal papers was 4.23, while their technology cycle time (TCT) value was 6.29. The SCT value of patents was 9.56, while their TCT value was 4.88. The science linkage value and technology linkage value between papers and patents was 82.39 and 0.012, respectively. T-tests indicated that the interaction between papers and patents was significant. Although there are many paper citations by patents, the distribution of paper citations was more scattered than patent citations by patents. Examining the paper and patent hybrid documents co-citation revealed that papers’ references contained five topics, while patents’ references contained only three.
