Not a dumb question at all. All points well-taken. But as discussed ad nauseam on this Board, this is about de-risking. No matter how strong Amarin thinks their case is, there are always risks of going to trial.
Quite to the contrary, a settlement, depending upon the terms, is not at all a misuse of shareholder assets. Many have stated that the existence of this specific litigation has been a drag on the assent of the stock price, while the settlement of the litigation will act as a major catalyst for the stock price. Settlement of the litigation may also be a condition set by a potential suitor. As I said previously, whatever is paid in the settlement will most likely be dwarfed by the gain in market cap.
As for copycat lawsuits, that is always a possibility no matter what happens here, because even if Amarin creamed the current challengers, futue challengers will attempt to distinguish this case.
