If they really can pull it off with this patent, online casinos and related services might get some headaches. How are patents handled in the US? Do you have to describe some kind of technical process/mechanisms? If they formulate it too narrowly and focusing on a certain technology then the patent's usefulness will be situational at best. If they describe it in a too general way would it still be considered a valid patent?
