This just seems silly. Why would anyone want a shock when their phone rings? And why is this something that can get a patent? It's not like getting a shock is something new. I've witness the event since 3rd grade when some of the more adventurus kids would stick rulers in the outlets. Besides, it would be simple to do on a phone. Just connect a couple wires to the vibrate motor and then tap them to your person. Making sure not to send the signal across the heart. Even still, I don't think it would be powerful enough.
Did I mention this was silly?
