Citation Bridge^TM is a free search utility lets you look up forward and backward U.S. Patent Citations (also called U.S. Patent References) on an individual patent and search back and forth through citation generations. Find out who's citing your patents and whom your patents are citing.

Here's How It Works…

After you have registered and logged in, enter a U.S. patent number in the search box and click Search to retrieve a Citation Bridge^TM of the patents citing your patent and those that your patent cites.

Click on any Title (listed next to each patent number in the Citation Bridge^TM) to view the title, inventor, assignee, abstract, issue date, and application date.

It's easy to search back and forth through citation generations. Simply click on any Patent Number, making that number the center of your Citation Bridge^TM, to generate a new Forward and Backward listing.
