United States Patent and Trademark Office Bulk Downloads

Google and the USPTO entered into an agreement in 2010 to make USPTO bulk data available at no charge. The USPTO now provides access to the data through its Bulk Data Storage System, and as a result Google's data mirror is no longer necessary.

Google packaged USPTO public PAIR data in bulk through 2012 and made it available at no charge. New bulk public PAIR data can be downloaded from Reed Tech.

These data sets are no longer being updated as of 2015. Please visit the USPTO's Electronic Bulk Data Products site for access to the latest downloads.

Patents (grants, published applications, assignments, classification information, and maintenance fee events)
Trademarks (registrations, applications, assignments, and TTAB proceedings)

All data originated from the USPTO. Google is hosting this data unchanged, except for repackaging into zip files.
