"We surmise that this immediate launch by Watson/Amphastar is a maneuver to elicit a patent settlement out of Momenta," Davis said. "A short partial launch by Watson followed by a quick settlement would have a positive, though not material, impact on Watson's 2012 numbers."
IMO the parties are gonna work towards a settlement... risk / reward analysis says that a settlement is the best outcome for both @ this point in time.
