Patent and Patent Application Claims Research Dataset for Academia and Researchers (1976 - 2014)uspto.data.commerce.gov | Last Updated 17 May 2018
Contains detailed information on claims from U.S. patents granted between January 1976 and December 2014 and U.S. patent applications published between March 15, 2001 and December 2014. The dataset is derived from the Patent Grant Full Text and Patent Application Full Text bulk data files. The Office of Chief Economist (OCE) applied a Python algorithm to identify individual claims as well as the dependency relationship between claims. From the parsed claims text, OCE created six data files containing individually-parsed claims, claim-level statistics, and document-level statistics, including newly-developed measures of patent scope.
