The patent litigation was filed by the Company in the United States District Court for the District of Delaware in response to Zydus notifying the Company that they had submitted an Abbreviated New Drug Application (ANDA) to the United States Food and Drug Administration seeking approval to market generic versions of INGREZZA prior to expiration of the Company’s Orange Book listed patents. As a result of the Zydus Agreement, the Company has granted Zydus the right to sell generic versions of INGREZZA in the United States beginning October 1, 2038, or earlier under certain circumstances.
