("Watson", now Actavis plc, NYSE:ACT) related to Watson's Abbreviated New Drug Application (ANDA) for a generic version of Absorica^® (isotretinoin capsules).

Background

In September 2013, Ranbaxy received a Paragraph IV Certification Notice of filing from Watson Laboratories, Inc. of an Abbreviated New Drug Application ("ANDA") to the U.S. Food and Drug Administration (FDA) for a generic version of Absorica^®, which is marketed in the U.S. by Ranbaxy.  Absorica is currently protected by three issued patents, which are listed in the FDA's Approved Drug Products List (Orange Book), which expire in September 2021. There are three additional new patent applications pending with the U.S. Patent and Trademark Office.  Cipher has been advised by Ranbaxy that the Paragraph IV filing has no impact on the current sales and marketing plans for the product and that Ranbaxy plans to continue to invest significantly in Absorica.
