All I could find was that Teva's first notice delt with DR. Reddy. I'm not prevy to know how the fda sends out the Para IV notice. It would seem rather quick for the FDA to 'accept' both Mylan's and Momenta's filing one month later if they hadn't filed earlier.
I think being that both Mylan and Momenta happened to be accepted concurrently the FDA is telegraphing its intent.
