Hace unos días encontraba esto, aún no lo he leído pero tiene buena pinta, quizá a alguien le interese. 'An Empirical Look at Software Patents' (PDF) de Mr James Bessen and Mr Robert M. Hunt:

"U.S. legal changes have made it easier to obtain patents on inventions that use software. Software patents now comprise 15% of all patents. Compared with other patents, software patents are more likely to be owned by large U.S. firms. Most are assigned to manufacturing firms; only 6% belong to software publishers. Our regression analysis finds that software patents have become a cheap form of appropriability. This cost advantage, not the profitability of software, accounts for most of their increased use. Also, software patents substitute for firm R&D rather than complement it. Their use is associated with substantially lower R&D intensity, consistent with strategic “patent thicket” behavior."
