Both Viagra and Cialis have Orange-Book patents running to Apr 2020. (Viagra just received a 6-month pediatric extension from the testing of Revatio in infant pulmonary hypertension: #msg-72269824, #msg-72270186.)
The phrase, “earlier under certain circumstances” means that if a company other than Teva launches a generic version of Viagra in the US before 12/11/17 (either as a result of a settlement or a court judgment), then Teva can launch on the same date as the other company. This is a strandard provision in these kinds of patent settlements.
The settlements terms are essentially the same as the ones in the PFE-TEVA deal in 2013 (#msg-95062675).
