PatentsView

PatentsView is a free, publicly accessible patent data exploration platform developed by the American Institutes for Research in partnership with the USPTO, covering granted patents (1976-present) and published applications (2001-present). It's built for researchers, analysts, entrepreneurs, educators, and patent examiners who need to search, visualize, download, or programmatically query patent, inventor, assignee, and location data. Its standout differentiator is advanced machine-learning inventor and assignee disambiguation, which links entities to themselves over time and makes longitudinal patent analysis possible.
