@Greedfighter: There is one detail that makes me think that nor India nor US will be able to stop the people's import of HCV drugs: the import is allowed due to the Art. 60 from TRIPS, so no matter what US and India will agree, I doubt this import will be stopped so easily.
If you look for instance at another case, at the DOHA DECLARATION, changes that are being made to an agreement that was already signed by several other countries takes a huge amount of time, by which, hopefully, more and more people would be treated by means of HCV medication.
