Not this time. They were for companies that actually sold products that were effective. Provenge is #$%$.
NO company will touch Dendreon. There may be a little merit in buying some of the patents during Dendreon's liquidation. Or maybe not? It all depends on when the patents were awarded. In time, they all run out. Perhaps Big Pharma will just wait until the patents expire?
Advice: Look at it from the vantage point of Big Pharma, not as a DNDN trader. Then it'll become soooo much clearer on how to trade DNDN stock and/or options.
