The Supreme Court has set the date for oral argument in Helsinn Healthcare S.A. v. Teva Pharmaceuticals USA Inc. as December 4, 2018.
Last week the Court also granted leave for the Solicitor General to participate in the oral argument as amicus curiae. And, Teva Pharmaceuticals filed its brief, available [here]. Also, an interesting admixture of intellectual property professors have signed on to what appears to be the single an amicus brief in support of Teva.
