George Dvorksy has an interesting article at io9 on the subject of gene patents, discussing the current litigation over the issue. This includes a quote that he got from me on the subject of contrived patents in general and on the so-called tragedy of the anti-commons (though I don't use that expression - the point is that, theoretically, intellectual property rights can be become too fragmented among different right-holders to operate in the public interest).
The article is worth reading, not only because it discusses my (rather wishy-washy) views sympathetically but also because it gives an up-to-date and accurate account of a tricky, often misunderstood, subject. Dvorsky has his own bias, but he's fair in presenting arguments from both sides of the debate without simply dismissing any of them or demonising people with whom he has disagreements.
There's also a vigorous discussion thread there, which looks like it may contain some worthwhile nuggets.
