I've read classified documents reflecting what Bush signed. There were over 1,000 delegates in Banff, Canada who met to iron out the details.
But even if that is not true and you are right, Gilead's strategy is simple. They are keeping their price high for years to come for harvoni and Sovaldi. By striking deals with Indian manufacturers they killed two birds with one stone: get some revenue from India, where the patent was denied, and be able to focus their influence over FDA to block the drugs from being imported from India. Since the majority of generics will come from India. Under TPP, unapproved generic versions of drugs under patent protection cannot be imported. Generic drugs still under patent will not be able to be imported even by personally carrying them, which is legal now.
