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.

description: The latest version of PatEx (referred to below as the 2020 release) contains detailed information on nearly 11.9 million publicly-viewable provisional and non-provisional patent applications to the USPTO and over 4.6 million Patent Cooperation Treaty (PCT) applications. It is based on data that OCE downloaded from the Patent Examination Data System (PEDS) in April, 2021. The PEDS data are sourced from Public PAIR. The first time that OCE used PEDS as the basis of PatEx was for the 2019 release. We took the PEDS data and organized it into the familiar PatEx data files, which are based on the organization of the Public PAIR portal. The data files include information on each application’s characteristics, prosecution history, continuation history, claims of foreign priority, patent term adjustment history, publication history, and correspondence address information.
