In this study, we analyse the distribution of examiner patent citations according to patent characteristics, to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technology. Howev...

متن کاملPatent Citations as a Measure of Knowledge Flows: the Influence of Examiner Citations
Analysis of patent citations is a core methodology in the study of knowledge diffusion. However, citations made by patent examiners have not been separately reported, adding unknown noise to the data. We leverage a recent change in the reporting of patent data showing citations added by examiners. The magnitude is high: two-thirds of citations on the average patent are inserted by examiners. Fu...
