What is Patent Data?

A patent is a set of exclusive rights granted to an inventor or assignee for a limited period of time in exchange for detailed public disclosure of an invention. Patents are a form of intellectual property. The USPTO makes patent public data available in bulk form, which can be used to load into databases or other analytical tools for research and analysis. USPTO searchable data is viewable through a search interface on the Open Data site.

  • Historical patent data files

    Patent classification systems are largely designed for administrative purposes, limiting their value for most research purposes. To address this deficiency, Hall, Jaffe, and Trajtenberg (2001) (link is external) developed a higher-level classification for the National Bureau of Economic Research (NBER) Patent Citation Data File by aggregating U.S. Patent Classification (USPC) classes into economically relevant technology categories. While this NBER classification scheme has proven valuable for researchers investigating US patent grants, comparable information on patent applications remained unavailable. For that reason, the Office of Chief Economist (OCE) developed a probability-matching algorithm to apply NBER classifications to patent applications as well as in-force and expired patents. From matched data, we construct the USPTO Historical Patent Data Files, four research datasets containing time series and micro-level data by NBER sub-category on applications, grants, and in-force patents spanning two centuries of innovation. Our hope is that researchers will make use of these data which, for the first time, enable detailed study of the complex dynamics between new filings, pendency, and abandonment and put into context recent trends in patenting activity, litigation, and technological change.
  • Patent assignment economics data for academia and researc...

    Contains detailed information on roughly 6 million patent assignments and other transactions recorded at the USPTO since 1970 and involving over 10 million patents and patent applications. For more information: http://www.uspto.gov/learning-and-resources/electronic-data-products/data.
  • Cancer Moonshot

    This curated dataset consists of 269,353 patent documents (published patent applications and granted patents) spanning the 1976 to 2016 period and is intended to help identify promising R&D on the horizon in diagnostics, therapeutics, data analytics, and model biological systems.

  • Office Actions

    Contains detailed information on 4.4 million Office actions mailed from 2008 through June 2017 for 2.2 million publicly viewable patent applications. The data are sourced from the text of Non-Final Rejection and Final Rejection Office actions issued by patent examiners to applicants during the patent examination process. The data files include information on grounds for rejection raised, the claims in question, and pertinent prior art.
