Full text XML, TIFF images, and bibliographic data for U.S. patents and trademarks are now available for bulk download free of charge from Google, according to a June 2, 2010 press release from the U.S. Patent and Trademark Office (USPTO). The trademark information includes data from 1870 to present, and the patent information includes data from 1976 to present.
According to the USPTO, the information available for download includes the following data or document types:
- “Patent grants and published applications
- Trademark applications
- Trademark Trial and Appeal Board (TTAB) proceedings
- Patent classification information
- Patent maintenance fee events
- Patent and Trademark assignments.”
According to the USPTO, “The USPTO and Google will be working together to make additional data available in the future, including patent and trademark file histories and related data.”
This provision of access to legal information in XML in bulk, with accompanying metadata, all free of charge, seems consistent with the goals of the Law.gov legal open government data project.
