Especially since it's undecidable (the proposed task being equivalent
to the halting problem)....

Seriously, I suspect that the enforcement of most software patents is
practically impossible, unless they involve some external program feature
such as an xor cursor or a +++ attention sequence.  For example, IBM has
a patent on register assignment via graph coloring -- how in the world
could an outsider detect that a compiler was using this?
