I have to agree with you that the damage done to mnta by ampha entrance and the judicial set back has been very heavy.
I do believe that given the fulness of time mnta will win their case against ampha. However like you say, the monetary damage mnta can recover from ampha/wpi may indeed be a pittance compared to the 3 or 4 golden quarters they enjoyed before the roof caved in, had that golden episode been allowed to continue.
And then, to my original question last year, how could they possibly dream of a 20% royalty from WPI/Ampha if the entire profit margin enjoyed by WPI/Ampha is 10% or less?
I agree that your being right on the cost erosion that occurred with even just 2 independent generics makes you correct on the royalty discussion for Lovenox as well. But at this point if the en banc reverses the previous ruling then A* (and WPI if the A* can't pay?) will just owe that much more money as penalty. NPV is NPV - whether it is discounted future royalties or cash now. Not sure anyone should care whether it is $1B now (WAG) and 20% royalty on 1/4 of the market in 3 years or $1.3B now and 2% royalty on 1/4 of market in 4.5 years
