To be honest, given the efficiency of the drug and the huge benefit it could be to society, I feel like if I had been the employee in charge of filing patents I would've more than ready to lose my job in exchange for low cost general availability in the US via (illegal maybe, whatever) cross-border market. It's a nice loop hole and a great thing that once the delay expired they can't file ever again.

One's got to find ways to feel like the good guy when working for Big Pharma . That's probably not what happened but it's nice imagining it.
