Thats really self-serving logic. Let me turn it around.
Based on the same principle, we can argue that if Teva loses, then the FDA should not approve Copaxone because a court has found that Novartis did not steal enough important data and hence the copy cannot be exact. If Teva wins, FDA cant approve because the court will bar it. So its actually a win-win for Teva rather than the lose-lose the way you portray it.
The flaw in your logic is that it assumes argument=fact and two arguments in differing venues cannot be contradictory. At least my logic above looks at impact of decisions rather than arguments.
