I was under impression that TEVA's [Copaxone] patents could potentially block it through 2014.
It depends what you mean by block.
Once the 30-month Hatch-Waxman clock expires, the FDA is no longer blocked from granting final approval for the ANDA. However, if Teva’s US patents remained valid, NVS/MNTA could potentially be ordered by a court to pay damages to Teva for launching an infringing product.
My guess is that NVS/MNTA won’t launch until Teva’s patents have expired or have been invalidated by a lower court. But NVS/MNTA could launch as soon as Feb 2011 if they have final FDA approval and they are willing to incur the risk of an adverse legal judgment.
