>>Sanofi has asked the US Supreme Court to review the ruling of patent invalidity based on inequitable conduct.
Petitioning for Cert is uphill even when you have a case where there are differing views* of the law from different Circuits. That is not possible here since patent appeals all go to the Federal Circuit. At least that is what I think. :-)
That would not prevent the Court accepting review if the concepts interested the Court.
If there are others who know better, please correct any of this since I am likely out of my depth. :-)
