USPTO Datasets

Contains the images of each patent application (non-provisional utility and plant) published weekly (Thursdays) from March 15, 2001 to present in Portable Document Format (PDF) created from the Patent Application Single-Page TIFF Images. Each weekly file contains approx. 6,000 patent applications. Approx. 11 GB (compressed) per week.

Contains the images of each patent application (non-provisional utility and plant) published weekly (Thursdays) from March 15, 2001 to present in Tagged Image File Format (TIFF) Revision 6.0 with CCITT Group 4 Compression (single-page TIFFs). Each weekly file contains approximately 6,000 published patent applications.

Contains (MAR 15, 2001 - present) the full text, images/drawings, and complex work units (tables, mathematical expressions, chemical structures, and genetic sequence data) of each patent application (non-provisional utility and plant) published weekly (Thursdays). The file format is eXtensible Markup Language (XML) in accordance with the Patent Application Version 4.4 International Common Element (ICE) Document Type Definition (DTD).

Contains (MAR 15, 2001 - present) the full text of each patent application (non-provisional utility and plant) published weekly (Thursdays) (excludes images/drawings). The file format is eXtensible Markup Language (XML) in accordance with the Patent Application Version 4.4 International Common Element (ICE) Document Type Definition (DTD).

Contains (MAR 15, 2001 - present) the bibliographic text (front page) of each patent application (non-provisional utility and plant) published weekly (Thursdays) (excludes images/drawings). The file format is eXtensible Markup Language (XML) in accordance with the Patent Application Version 4.4 International Common Element (ICE) Document Type Definition (DTD).

Trademark Assignments: Assignment text data (no images) in CY2022. The file format is eXtensible Markup Language (XML) in accordance with the U.S. Trademark Assignments Version 0.4 Document Type Definition (DTD).

Published each Tuesday, the Patent Official Gazette contains bibliographic (front page) information, a representative claim, and a drawing (if applicable) of each patent grant issued that week. Includes U.S. Patent and Trademark Office (USPTO) Notices which provide important information and changes in rules concerning both patents and trademarks.

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!

  

Contains detailed information on 9.2 million publicly viewable patent applications filed with the USPTO through December 2021. The data are sourced from the Public Patent Application Information Retrieval (Public PAIR) system. There are several data files, each of which coincides with a tab on USPTO's Public PAIR web 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.

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
