Again, as a layperson, it seems to me that MNTA has been saying all along that to manufacture the generic one must violate their patents.
MNTA is saying they found the key to the puzzle and patented it. IF others use THAT KEY they would violate the patent. They conclude that others are violating the patent by inference from the fact they could not find another key.
For SNY, they never needed to find the key. They made a composition and got FDA approval. All they had to do is keep cooking the batches the same way.

It is astonishing what foolish things one can temporarily believe if one thinks too long alone ... where it is often impossible to bring one's ideas to a conclusive test either formal or experimental. J.M. Keynes
