I covered that in the article:

"In particular, Boldrin and Levine devote a chapter of their book, Against Intellectual Monopoly, to the pharmaceutical industry. They argue that the actual cost of bringing drugs to market is substantially lower than the estimates produced by the pharmaceutical industry — a group with a vested interest in lobbying for strong patent protections. They also provide evidence that in many instances the existence of patents hinders research in drug production."
