No one is arguing that the Generics are not infringing, they clearly are.
But if the lab tests were to reveal differences, regardless of how small, if the FDA weren't going to act, the Generics would get obliterated in the court of public opinion. I would gladly lead the way.
The results may not be actionable in an infringement action by Amarin, but they would potentially be actionable from the consumer's end under consumer fraud laws if the results scientifically establish that generic V is inferior to brand name V.
