Patent Assignments

This solution allows you to quickly look up any US patent assignments for a given company name, US patent number, US pre-grant publication number, or US patent application serial number in the USPTO patent assignment database.

Select a company name, US patent number, US pre-grant publication number, or US patent application serial number in webpage text, then open the context menu and select "Open USPTO Assignments" from the menu. You can normally open the context menu by right-clicking.

The extension should work for any webpage loaded after the initial installation of the extension, as long as JavaScript is enabled.

Just let me know of any issues you experience before writing a review -- I'm happy to continue to improve the solution. The extension is provided 'As-Is' without any express or implied warranty of any kind.

Note that I do not collect any information from the extension -- all handling is done at your local browser.

Enjoy!
