terms of_use: USPTO’s online databases are not designed or intended to be a source for bulk downloads of USPTO data when accessed through the website’s interfaces. Individuals, companies, IP addresses, or blocks of IP addresses who, in effect, deny or decrease service by generating unusually high numbers of database accesses (searches, pages, or hits), whether generated manually or in an automated fashion, may be denied access to USPTO servers without notice. Bulk data products may be separately obtained from the USPTO, either for free or at the cost of dissemination. For details, see information on Electronic Bulk Data Products:

description: 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, 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.
