Patent Citations to Science

This dataset contains citations from USPTO patents granted 1947-2018 to articles captured by the Microsoft Academic Graph (ID) from 1800-2018. All files in this distribution are compressed using ZIP compression, except the reliance_on_science.pdf documentation which is provided uncompressed. 

The main file, pcs.zip, contains the resolved citations. Each has the patent number, MAG ID, the original citation from the patent, an indicator for whether the citation was supplied by the applicant, examiner, or unknown, and a confidence score (1-10) indicating how likely this match is correct. Note that this distribution does not contain matches with confidence 2 or 1.

The remaining files are a redistribution of the 1 January 2019 release of the Microsoft Academic Graph. Original files can be downloaded from https://aka.ms/msracad; this redistribution carves up the original files into smaller, variable-specific files that can be loaded individually (see reliance_on_science.pdf for full details, the latest version of which is available at https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3331686).
