An anonymous reader writes "Current orthodoxy claims patents encourage innovation, by allowing developers to enjoy profitable monopolies on their inventions which in turn inspire them to create new inventions. A new report by the non-partisan General Accounting Office suggests that this orthodoxy is wrong — at least when drug companies are involved. According to the report, existing patent law allows drug companies to patent, and make substantial profits off of, "new" drugs which differ little from existing medicines. Given high profit margins on very minor innovations, the report argues that drug companies have little incentive to produce innovative new drugs. In other words, current patent law actually discourages drug companies from producing new medicines. Responding to the report, Senator Dick Durbin (D-IL) released a strongly worded statement suggesting that a legislative response will be forthcoming. "The findings in this new GAO report," said Senator Durbin, "raise serious questions about the pharmaceutical industry claims that there is a connection between new drug development and the soaring price of drugs already on the market. Most troubling is the notion that pharmaceutical industry profits are coming at the expense of consumers in the form of higher prices and fewer new drugs.""
