USPTO Datasets

The USPTO Trademark Daily Application Image 24 Hour Box (XML/TIFF/JPEG) consists of two datasets: (A) 24 Hour Box file, hryymmdd.zip & (B) 24 Hour Box Supplemental file, hrsyymmdda.zip, with optional files, hrsyymmddb.zip, hrsyymmddc.zip, etc. (A) The 24 Hour Box zipfile contains images of daily Trademark applications in either JPG format (black and white, grayscale, or color) or TIFF format (black and white) processed through the Trademark Image Capture and Retrieval System (TICRS) and viewable using any standard image viewer. (B) The 24 Hour Box Supplemental zipfile(s) contain Trademark cropped TIFF (black and white) or cropped JPG (color) image files from paper submissions of Trademark applications.

Contains the images of each patent grant issued weekly (Tuesdays) from July 31, 1790 to present in Portable Document Format (PDF) created from the Patent Grant Single-Page TIFF Images. Also included are older grants that have new Certificates-of-Correction (C-of-C) and rescanned images of older patent grants. Each weekly file contains approx. 6,000 patent grants. Approx. 9 GB (compressed) per week.

Contains the images of each patent grant issued weekly (Tuesdays) from July 31, 1790 to present 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

Contains (JAN 2002 - present) 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). The file format is extensible Markup Language (XML) in accordance with the Patent Grant Version 4.5 International Common Element (ICE) Document Type Definition (DTD).

Contains (JAN 2002 - present) the full text of each patent grant issued weekly (Tuesdays) (excludes images/drawings and reexaminations). The file format is eXtensible Markup Language (XML) in accordance with the Patent Grant International Common Element (ICE) Document Type Definition (DTD).

Contains (JAN 2002 - present) the bibliographic text (front page) of each patent grant issued weekly (Tuesdays) (excludes images/drawings and reexaminations). The file format is eXtensible Markup Language (XML) in accordance with the Patent Grant International Common Element (ICE) Document Type Definition (DTD).

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.

Bnnnnn.tar: Rescans of miscellaneous documents from miscellaneous years (1790 - present). The filename relates to the Digital Linear Tape (DLT) cartridge.

The USPTO receives millions of patent applications and supporting documents each year. During the application process, inventors sometimes submit documents using alternative versions of their names. As raised in the USPTO directors blog (dated September 08, 2021), this can limit the office’s ability to accurately certify the number of applications from a specific inventor and determine whether inventors are following application fee rules and regulations. Certifications submitted with errors often mean longer wait times for all applicants.

Prior to this sample USPTO dataset, identifying patent application discrepancies required manually reviewing millions of documents to match names and signatures. Patent documents come in different formats and languages and can contain multiple inventors for each application. Signatures exist in various locations within a document, making signature to applicant name matching challenging.

This sample USPTO research dataset provides images of signatures extracted from inventor oath documents.  This data set could be used for validation of micro entity certifications or other research purposes. It includes 883,811 applications and oath document signature images. Its is 40.5 GB of total size and is broken as 8 zip files for the following Patent Application Series:

Application # Series	Applications	Signature Counts
12	160,116	292,354
13	156,284	282,303
14	159,067	304,182
15	154,964	305,029
16	134,728	260,884
17	58,718	112,406
29	58,125	84,123
35	1,809	1,984
Total	883,811	1,643,265

 

Each of these zip files contain folders for each application number in a given series. The application folders contain the oath document identifier that includes the image(s) of the signature(s) as PNG, and JSON file that contains the application number, the inventor name(s), and confidence level of the signature extraction algorithm.

Fun Fact: This research data set includes a few celebrity signature images such as Elon Musk and Lori Greiner. See if you can identify the others!
