Patent and patent application Claims data (Stata (.dta) and MS Excel (.csv))

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.

Patent term adjustments

The Patent Term Adjustment (PTA) statute at issue is 35 USC 154(b)(2)(c), which provides for a deduction from any PTA award "equal to the period of time during which the applicant failed to engage in reasonable efforts to conclude prosecution of the application." The statute also expressly delegates to the USPTO the authority to "prescribe regulations establishing the circumstances that constitute a failure of an applicant to engage in reasonable efforts to conclude processing or examination of an application."
