A Quote by Lawrence Lessig on drugs and patents

These prices are not high because the ingredients of the drugs are expensive. These prices are high because the drugs are protected by patents.The drug companies that produced these life-saving mixes enjoy at least a twenty-year monopoly for their inventions.They use that monopoly power to extract the most they can from the market.That power is in turn used to keep the prices high.
