- Independent claim numbers
- Independent claim word count
- Independent claim type (best effort)
- Independent claim text
- Dependent claim numbers
- Hierarchical dependencies
- Priority date (Google Patents only)

Select the red claims tree icon on the toolbar in the Chrome browser to see a patent claims tree and associated details. You may need to pin the extension to keep it visible in the toolbar.
Currently supported on the following websites (at least partially):
- USPTO
- Google Patents (.com, .de, .fr, .co.uk, .se, .ca, co.in, co.nz currently -- send me requests for additional countries). Currently US, EP, WO, and CA patent documents are handled. A future update will also handle documents from other jurisdictions such as DE.
- FreePatentsOnline
- Espacenet
We do our best to present the claims trees and information correctly, but we cannot guarantee results because the supported websites are dynamic and often changing.
The extension is provided ‘As-Is’ without any express or implied warranty of any kind.
The extension should work for a webpage loaded after the initial installation of the extension, as long as JavaScript is enabled.
Note that no information is collected or transmitted from the extension -- all webpage information handling is done only at your local browser in the extension.
Multiple dependent claims are not currently fully supported. Also, only claims in English are currently fully supported. Some basic French and German handling is provided.
Visited links on Google Patents pages are highlighted, facilitating review projects.
