Smoothing the lies: Do patent examiners take notice if applicants include citations?

ResumenExaminer patent citations are a popular source of indicators of technological impact and knowledge flows, despite various critiques. We analyse the distribution of examiner patent citations according to patent characteristics, to show their comparative meaningless. Our findings show that it is the science-base of the technology that determines the inclusion of applicant citations. However, this gets masked by the citations added by patent examiners, who smooth the distribution of citations across technology classes and include the ‘standard’ knowledge bases regardless of which references applicants cite. Some researchers have called for the use of applicant rather than examiner patent citations to build indicators of technology impact and knowledge flows. However, we show that the former are not necessarily ‘better’ than the latter, because applicants may ‘inflate’ the numbers in international patents especially when there are co-applicants. The implications are that analysts should consider alternative uses of patent citations e.g. to build indicators of trust within a research system.
