I just initiated a position recently, so as far as this company's history I may not be that well versed, but from the filings to date, I think DECN would be crazy to entertain most settlement offers before the court's ruling. JNJ would likely continue to lowball. If the court either decides the case should go forward (most likely, IMO) or that DECN has sufficiently laid out its case (unlikely, IMO), any settlement offer would be several multiples higher. If the court somehow finds for JNJ, no big loss from what is likely to be a (relativey) negligible settlement offer.

There's an outlier scenario where JNJ realizes how weak their position is and offers something in the 10% range, but they don't seem too smart. Again, could be wrong.
