Six Degrees of the Roomba

As we all may have noticed at some point there is a list of references cited adorning the face of every US patent. Utilizing these lists of references cited, patents can be connected to other patents through the references cited on their own face, as well as the instances where the patent is cited on a subsequent patents face. By connecting patents in this manner a network begins to form and begs the question: How many steps would it take to connect any patent with any other patent?

So, starting with any patent where would we find ourselves after 6 steps through the references cited network? Today our search dives into a fantasy world where everyone goes home and kicks up their feet while compliant robots take care of the boring housework.
