First, patent lawyers are clever at reformulating patents to fit whatever rules may apply; they transform any attempt at limiting the substance of patents into a requirement of mere form. For instance, many US computational idea patents describe a system including an arithmetic unit, an instruction sequencer, a memory, plus controls to carry out a particular computation. This is a peculiar way of describing a computer running a program that does a certain computation; it was designed to make the patent application satisfy criteria that the US patent system was believed for a time to require.
