This historical dataset is constructed using digitalized records of original patent documents that are publicly available. HistPat can be used in different disciplines ranging from geography, economics, history, network science, and science and technology studies. Additionally, it can easily be merged with post-1975 USPTO digital patent data to extend it until today.</abstract><sumDscr><timePrd cycle="P1" event="start" date="1790">1790</timePrd><timePrd cycle="P1" event="end" date="1975">1975</timePrd><dataKind>Patent Data</dataKind></sumDscr><notes>If you want to get a notification whenever the database is updated send us an E-mail.</notes></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt><citReq>Petralia, Sergio, Pierre-Alexandre Balland, and David L.
