"Of course, you could try to respond to this by defining software as a set of instructions to be performed by a programmable computer. But this overlooks the problem that most technical processes nowadays are computer-controlled. Again, you could try (as some FFII-backed MEPs did during the CII patents directive debate) to restrict patentability to only those technical processes which make use of "forces of nature". The first trouble here is that even "pure software" makes use of "forces of nature" within the microprocessor. Even marketing processes make use of forces of nature governing our brains. So this could become quite a meaningless restriction, and even if it was applied restrictively it would leave, for instance, sound or image processing methods in a grey area."
