Patent Application Retrieval (PAIR) System
Public PAIR is the Patent Application Information Retrieval System.
Public PAIR extract documents contain patent ownership information.
Contains published patent applications includes both text and image content from the USPTO Public Patent Application Information Retrieval (PAIR) System. The text is tab delimited (.tsv) and the images are in Adobe format (.pdf). Each zip file 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.
