Current U.S. classification information for all patent grants issued by the U.S. Patent and Trademark Office from 1790 to May 2018. Approximately 450 main divisions of technology, called classifications/classes, broken into approximately 150,000 subdivisions, called subclassifications/subclasses.

Registered patent practitioners are individuals who have passed the USPTO's registration exam and met the qualifications to represent patent applicants before the USPTO.

Trademark practitioners are attorneys who are active members in good standing of the bar of the highest court of any State.

NOTE: Because Trademark attorneys need not apply for registration to practice trademark law before the USPTO, the USPTO does not maintain a roster of trademark attorneys. The names of attorneys who specialize in trademark law may be found in the telephone yellow pages, or by contacting a local bar association. Most state bar websites offer a searchable online registry of their attorneys, and many bar associations operate attorney referral service programs.

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. JPG images are accompanied by an XML file that contains text information about the application. TIFF images contain the application number embedded in the image (stamped prior to scan).

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. These cropped images are available one day after they appear as full-page drawing images in the 24 Hour Box zipfiles.

Contains detailed information on 786,931 assignments and other transactions recorded at the USPTO between 1952 and 2018 and involving 1,491,485 million unique trademark properties.

Contains the bibliographic text (front page) of each patent application (non-provisional utility and plant) published weekly (Thursdays) from March 15, 2001 to present (excludes images/drawings). Subset of the Patent Application Full Text Data.

Under the current Public Dissemination of Data (PDD) no-cost contract (expires April 13, 2020), Reed Tech crawls the USPTO Public PAIR (Patent Application Information Retrieval) website for patent documents, including Content Management System (CMS) PDF images (formerly the Image File Wrappers (IFW) PDF images). This daily crawl is for five hours each night and retrieves both already-submitted documents and new documents as the USPTO makes them publicly available.

Except for repackaging into zip files, these documents are hosted by Reed Tech unchanged. A single zip file is created for each patent application. There is detailed documentation about the format as well as the overview below.

How to access PAIR data:
To access a particular zipfile, replace APP_NUM in the following URL with an application number of interest:
http://patents.reedtech.com/downloads/pair/APP_NUM.zip

For example: http://patents.reedtech.com/downloads/pair/12102391.zip

Over 7,624,417 applications are available. Additional applications will be added regularly as the crawl progresses.

Overview of zipfile contents:
Each zipfile contains the following:
•A README.txt file which indicates when the data was obtained.
•Data files (*.tsv), in tab-delimited text format, compatible with many spreadsheet programs. Each data file represents one tab from the PAIR interface: Address and Attorney/Agent, Application Data, Continuity Data, Foreign Priority, Image File Wrapper, Patent Term Adjustments / Extension History, Transaction History.
◦Data tables from the PAIR interface are organized in one of two ways:
1. Labels in the first column. (Example: Application Data tab.) The second column contains the corresponding value (example: Application number and 12/102,391).
2. Labels in the first row. (Example: Transaction History tab, with labels such as Date and Transaction Description.) Each subsequent row contains the corresponding values for one data item. (In the example, each row represents a single transaction.)
◦Some *.tsv files contain more than one table, separated by a blank line.
◦The Image File Wrapper data file is put in a separate directory along with the additional content that it links to. An extra Filename column is added to the *.tsv file to indicate the appropriate file for each item.
•Image files (*.pdf), in Adobe PDF format. This data is only available for patent applications which have an Image File Wrapper tab on the USPTO PAIR site.

Disclaimer:
No guarantees are made with respect to the completeness or accuracy of this data. In particular, the crawl may discover and retrieve additional documents over time, even for applications submitted long ago.
