    • Patent Examination Research Dataset (PatEx) for Academia and Researchers (2001 - 2023)

    Metadata Updated: September 30, 2025

    Contains detailed information on more than 13 million publicly-viewable provisional and non-provisional patent applications to the USPTO and over 1 million Patent Cooperation Treaty (PCT) applications. It is based on data that OCE downloaded from the Patent Examination Data System (PEDS) in June, 2023. There are several data files, each of which coincides with a tab on USPTOs Patent Examination Data System (PEDS). The 2022 PatEx release includes some information that has not been made available in previous years. The release includes data on patent applicants in addition to inventors (all_applicants). It includes metadata on patent examination-related documents which are sourced from the CMS (cms_documents and cms_document_codes).
