Yes, though AW's ability to do that will be litigated in the injunction phase, so I doubt it will come to that.
No, it's only the key to AW's liability under MNTA's patents. As you state below, I don't think the FDA cares one way or another vis a' vis its approval. However if--as MNTA has stated many times--the FDA echoed the substance of MNTA's technology in its published "roadmap," it does seem likely that the FDA may have forced AW into violating them.
Yes, but see my answer above.
Yes, my view is that the FDA issued its roadmap without regard to whether forcing MNTA's competitors to follow that route would cause them to be liable for patent infringement--the FDA obviously felt that it was the best route from a scientific standpoint. Perhaps this factor could be argued by the defense to oppose multiple damages, along the lines of, "We were only doing what we were told."
