4. Agreement with Sanofi-Aventis SA

 

In 1997, we entered into an exclusive license agreement with Sanofi-Aventis. The agreement gave us a worldwide license to the patent rights and know-how related to the antipsychotic agent iloperidone, including the ability to develop, use, sublicense, manufacture and sell products and processes claimed in the patent rights. The license agreement provided that we pay royalties based on net sales. The underlying patent rights expired in November 2016.
