Not really. We have 3 year exclusivity per the FDA Hatchmann Act. Purdue can't get NDA until Oct 2016. Then Purdue would have to challenge the patent, we would sue, and the FDA WOULD HAVE TO grant a 30 MONTH STAY!!!! By then our AD product would be on the street and patent extended. See why Purdue is using their $600 Million per quarter revenue from OxyContin to sink Zogenix!?!??!
