We would like Return to download and absorb data from this location on the USPTO website into our tables. The objective is to determine whether this dataset is better than the current version of our patent data (a combination of the data in the patent_2015 and patentdata databases[[Patent Data]].
The XML files are available at https://bulkdata.uspto.gov/data2/patent/assignment/

<section begin=bulk />The USPTO provides bulk data recording patent transactions, applications, properties, reassignments, and history through XML files to the general public. These files have been downloaded and the data has been compiled in tables using PostgreSQL. The objective of processing the bulk data is to enhance the McNair Center's historical datasets ([[Patent Data Processing - SQL Steps|patent_2015 and patentdata]]) and track the entirety of US patent activity, specifically concerning utility patents. <section end=bulk /> == Steps Followed to Extract the USPTO Assignees Data ==
===Extracting Data from XML Files ===
== Scripts for processing data ==
The programs/scripts (see details below) are located at on our [[Software Repository|Bonobo Git Server]].
repository: Patent_Data_Parser
branch: next
directory: /uspto_assignees_xml_parser
file: USPTO_Assignee_Download.pl
The down-loader script used to download XML files is essentially same, with minor changes, as the one used for downloading USPTO patent-data.
That is, the current version of down-loader script downloads all files from the base URL (see above): https://bulkdata.uspto.gov/data2/patent/assignment/
=== Parsing the XML files ===
