I think you are wrong. In Europe, for example, a software algorithm is only patentable as part of a physical method and only as far as that physical method is concerned. So you can patent an algorithm that imitates a servomechanism to keep a motor from stalling but that patent only applies to the physical system it is embedded in. I can freely use the same algorithm to, say, control the pressure of a boiler, if it is appliable.
That is, unless I have misread or forgot something.
