MNTA: If your proposed explanation is, indeed, fact then it suggests that Teva knew they would have great difficulty defending Copaxone. It further suggests that the Court also saw this. Bullish for MNTA. A less plausible explanation is simple oversight/incompetence/arrogance. Arrogance: Perhaps Teva never expected a generic.
