It's not like NVS/MNTA can tell the FDA "Our drug is made using the same process that Teva uses - this we know for sure, because we stole their trade secrets."
However, this notion has already been planted by virtue of Teva’s filing its lawsuit, and I presume that FDA staffers are aware of some of the legal machinations in the Copaxone patent case. Such awareness could perhaps color the review process in NVS/MNTA’s favor, perhaps even subliminally.
Teva must have belatedly realized that alleging theft of Copaxone trade secrets was a losing game. These charges are no longer part of the ongoing litigation.
