anyway that won't work because.. you thought you were buying that software eh? Nope, you are just licensing it.. You thought you might buy a john deere tractor? Nope.. you just licensed the right to use it. sure, you might own the axle nuts but not the software that drives the engine. You say they can't sell the patent? Oh thats ok, they will just license it..

the real problem is that simple & obvious processes are granted patents by the US patent office, and that is what needs to be fixed first.
