Google is one of the leaders in innovation. The recent one is TiSP(http://www.google.com/tisp/)
Google TiSP (BETA) is a fully functional, end-to-end system that provides in-home wireless access by connecting your commode-based TiSP wireless router to one of thousands of TiSP Access Nodes via fiber-optic cable strung through your local municipal sewage lines.
And no one would have actually thought of patenting the technique of Flushing the Toilet :)
"Grasp both ends of the spindle firmly while a friend or loved one flushes, thus activating the patented GFlush™ system, which sends the weighted cable surfing through the plumbing system to one of the thousands of TiSP Access Nodes." Google it just think differently.
