This dataset contains both front-page and in-text citations from patents to scientific articles through 2020.  If you use the data, please cite these two articles:

1. M. Marx & A. Fuegi, "Reliance on Science by Inventors: Hybrid Extraction of In-text Patent-to-Article Citations."  forthcoming in Journal of Economics and Management Strategy. (

2. M. Marx, & A. Fuegi, "Reliance on Science: Worldwide Front-Page Patent Citations to Scientific Articles" (2020), Strategic Management Journal 41(9):1572-1594. (


The datafile containing the citations is _pcs_mag_doi_pmid.tsv. DOIs and PMIDs provided where available. Each citation has the applicant/examiner flag, confidence score (1-10), and whether the reference was a) only on the front page, b) only in the body text, or c) in both. Each paper-patent citation also includes a preview release (think: alpha, not beta) of the temporal gap (in months) and three related measures of self-citation (i.e., was one or more of the inventors on the citing patent also an author on the cited paper). _data_description.pdf has full details. bodytextknowngood.tsv contains the known-good references for calculating recall.
