Google hosts USPTO Patent Data for 2 years – Download USPTO ZIP Files
Google just signed an agreement to host all of the Patent and Trademark Raw Data from the USPTO.
The Google Patent About Page added this comment:
Q. Why does Google offer bulk downloads of patent and trademark information?A. Google and the US Patent and Trademark Office have partnered to provide bulk file downloads of patent and trademark information to everyone, for free. This information is also available on a file-by-file basis from the USPTO website, or for bulk download on CDs, DVDs, or digital tape, with fees to cover the USPTO’s expenses (often more than $10,000 and potentially up to $250,000). Many major law firms and research organizations rely on bulk file downloads so they can do more comprehensive analysis of the data. Now anyone can get the information for free by visiting http://www.google.com/googlebooks/uspto.html.
So, for all you data crunchers out there – here’s your chance to get your hands dirty. Previously, this data was hidden on a little known FTP server.
