If you ask me, if patents on software should ever be allowed, it
should be required that the description is accompanied by a formal
specification in a common modelling language, like Z, Larch, VDM or
whatever. This would clarify what the people really mean, avoid spongy
description like the above, and be actually a real win for other
people going to implement the stuff. And patents would be much less
:-], and equivalence could be decidable.
