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." This move gives Brazil one more thing in common with Thailand, both of which have blocked YouTube. Thailand's compulsory licensing of Elfavirenz and Plavix has landed the country on the US's watch list for piracy.
