Claims Data is offered in two categories. Claims for patents granted before 2005 and after for patents granted in and after 2005. We make this distinction as a consequence of making certain improvements in parsing XML formatted USPTO provided bulk files. These improvements include improved mathematical formula parsing, retaining newlines in claim text and other improvements. Please review the updated data dictionary or reach out to with any questions.

The PatentsView database is sourced from USPTO -provided text and XML data on published patent applications (2001-most recent update) and granted patents (1976-most recent update). The current PatentsView database MySQL dump is available for download, upon request. The patent applications database, which contains all granted and non-granted applications, is also available upon request. After March, 2016, the applications database will not contain the same inventor IDs as the PatentsView database. Only inventors on granted applications can be matched between the PatentsView and applications databases via a granted application ID.

From the PatentsView database, simple assignee and lawyer disambiguations are performed, and the patents are geocoded with a location-based disambiguation. Data are then fed into the inventor disambiguation algorithm in order to identify clusters of inventor names that are determined to be the same individual. Because the disambiguation of inventor identities is an ongoing effort, there are likely to be errors observable in the PatentsView data tables. The team welcomes feedback as we continue to improve our disambiguation methodology.
