Citations from patents to other patents have frequently been employed in studies of innovation, but these citations have many limitations. By contrast, citations from patents to non-patent materials—especially scientific articles—promise to be more useful but are much more difficult to discern given that they appear in patent documents as unstructured text. We present methods for automatically linking patents to scientific papers from 1800-2018 and share the results publicly. Moreover, we characterize the performance of our algorithms and present ROC curves so that researchers can select data according to their sensitivity to false positives vs. false negatives. Our hope is that publicly-available patent citations to science fuel research on innovation, knowledge diffusion, technology commercialization, and other topics.
