Brazil voids Merck AIDS drug patent

JoeBackward writes: "Merck has this useful anti-AIDS drug Elfavirenz, and Brazil has lots of poor people with AIDS. So, after trying really hard to get Merck to cooperate on pricing, the Brazilian government has decided to take a "compulsory license" to the patent, and get the drug from a factory in India. This "compulsory license" is basically a way to take the patent by eminent domain. Check out this story from the Reuters news agency."
