A new Open Data Portal (ODP) is launching soon! Developer Hub will continue to run in parallel with the new ODP through 2025. Thank you for your help in moving us out of beta. Learn more about the new Open Data Portal on data.uspto.gov.
USPTO Datasets
Protecting inventors and entrepreneurs fuels innovation and creativity, driving advances that can benefit society. As the federal agency that grants patents and registers trademarks, we hold a treasure trove of data. Now we’re giving it to you - faster and easier than before.
Certificates include post issuance documents, e.g., ex parte and inter partes reexamination documents. These were weekly and are daily starting on Ocotober of 2012.
Contains the images of each patent grant issued weekly (Tuesdays) from July 31, 1790 to December 26, 2023 in Tagged Image File Format (TIFF) Revision 6.0 with CCITT Group 4 Compression (single-page TIFFs). Includes a separate weekly Certificates-of-Correction (C-of-C) file and a daily Certificates file.
Certificates-of-Correction (C-of-C) File (2010 - present) contains a listing of all Certificates of Correction for US patent documents and lists the following fields: Document Number; Publication Date; and Kind of Document Code (always "X6"). Layout information for the Certificates of Correction File is provided and additional information regarding Certificates of Correction can be found on the list at the following location https://www.uspto.gov/patents-getting-started/general-information-concerning-patents#heading-26
Bnnnnn.tar: Rescans of miscellaneous documents from miscellaneous years (1790 - present). The filename relates to the Digital Linear Tape (DLT) cartridge.
These documents replace the original data disseminated by the Electronic Information Products Division (EIPD). For more information on the data, contact ipd@uspto.gov (link sends e-mail).
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."
These historical statistics are data for requests for reexamination filed since 7/1/1981 (for ex parte) or since 11/29/1999 (for inter partes). They are updated weekly.
Contains (JAN 1976 - DEC 2001) the full text of each patent grant issued weekly (Tuesdays) (excludes images/drawings and reexaminations). The file format is Green Book, ASCII text and includes tables and "in-line" mathematical equations.
Contains the full text, images/drawings, and complex work units (tables, mathematical expressions, chemical structures, and genetic sequence data) of each patent grant (excludes reexaminations) issued weekly (Tuesdays) in CY2001. The file format is Standard Generalized Markup Language (SGML) in accordance with the U.S. Patent Grant Version 2.4 Document Type Definition (DTD).
