This website provides all bibliographic data for USPTO patent applications from the start of its publication in March 2001 up until June 2016 freely and solely for research purposes. Given that around 50% of all patent applications are rejected, it may be relevant to use patent applications over patent grants.
Disclaimer: this dataset has been collected from free and publicly available sources. All copyright remains with the original information providers (USPTO and/or patent applicant). You may only use this dataset for non-commercial purposes.
