Patent Family Tree
This tool creates a basic diagram of the patent family based upon the same information available via PAIR (but in a graphical and more useful format). The resulting diagram identifies cited parents and identifies all descendents of the patent or patent application.
Unfortunately, this tool has been removed. The patent office has restricted web access to their PAIR system which prevents us from being able to generate our graphical representation of patent family trees. We apologize for the inconvenience.
