Provides a patent claims tree for a given patent.
Displays a patent claims tree for all patent claims listed on a current webpage.
Select the red and black "WM" icon on the right side of the address bar in the Chrome browser to see a patent claims tree.
Currently supported on the following websites (at least partially):
- Google Patents (.com, .de, .fr, .co.uk, .se, .ca, co.in, co.nz currently -- send me requests for additional countries).
We at Wolf Mountain IP, LLC do our best to present the claims trees correctly, but we do not guarantee results because the supported websites are dynamic and often changing -- so PLEASE LET US KNOW OF ANY ISSUES YOU ENCOUNTER. The extension is provided 'As-Is' without any express or implied warranty of any kind.
Note that no information is collected from the extension -- all handling is done at your local browser.
Multiple dependent claims are not currently fully supported. Also, only claims in English are currently supported.
