[Note, most of this stuff I'm not certain about, they're just nuggets
stored in my head somewhere.]
One effect of patenting algorithms is that they don't make it into
free compilers. I know GCC actively avoids patented algorithms, and
remember reading about one algorithm they would prefer to have used
that they couldn't (I think it was for register allocation).
I believe a problematic patented compiler algorithm is Steengaard's
unification based alias analysis. It was (originally at least) faster
than Andersen's, but patented and so avoided.
A point to consider for compiler patents is that no-one really makes
any money off compilers...
