Could you expand on what you think MNTA will "discover" that will prompt Amphastar (and MNTA, to be sure) to settle out of court?
I have no idea what, if anything, will be found of consequence during the discovery phase. However, the mere fact that the Judge allows discovery ought to be enough to induce the parties to entertain serious settlement discussions. The stakes in this case are too high for them not to, IMO.
