Nicox SA announced that the United States Patent and Trademark Office (USPTO) has determined that U.S. Patent No. 7,629,345, which covers latanoprostene bunod, commercialized by Bausch + Lomb under the trademark VYZULTA, is eligible for patent term extension of five years. Nicox has also applied for patent term extension of two other patents covering latanoprostene bunod, U.S. patent Nos. 7,273,946 and 8,058,467.

Nicox, in collaboration with Bausch + Lomb, must now elect which patent will be the subject of the patent term extension, and, depending on the choice of the patent, this may lead to an extension to either 2029 or 2030.
