<quote>I don't think patent infringement counts if it is from the user</quote>. 7 upvotes at the time of writing, indicating that lots of people think as you do, but I'm afraid it is wishful thinking. If I or you use a WiFi device which "practices" the patent (in the jargon) and for which a license has not been paid, then we're infringing the patent. We don't have to be reselling the WiFi service (as the hotel chains and coffee shops are), or making any money at all. You, or the manufacturer of the device, must license the patent, to buy out the monopoly which the state (USA in this case) has granted. There is only the economic imbalance of court and lawyer costs which makes it impractical for Innovatio to sue individual WiFi users in the US.
As I understand it, the recent America Invents Act of Congress forbids companies from sueing a group of infringers in a single suit (if the infringing action is the only common factor), so I think individuals can breathe easily. The US Patent system is still broken, though.
