The Patent Claims Research Dataset contain detailed information on claims from U.S. patents granted between 1976 and 2014 and U.S. patent applications published between 2001 and 2014. The dataset is derived from the Patent Application Publication Full-Text and Patent Grant Full Text files, available at https://bulkdata.uspto.gov/, to which 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.
A document describing the motivation behind and trends of the patent scope measurements is available and can be cited as: Marco, Alan C. and Sarnoff, Joshua D. and deGrazia, Charles, Patent Claims and Patent Scope (October 2016).
