(Reuters) – Mayne Pharma has filed a patent infringement lawsuit against Indian drugmaker Sun Pharma in a U.S. court, the Australian drugmaker said on Thursday.
In the lawsuit filed at the United States District Court for New Jersey, Mayne Pharma accused its rival of violating all 20 Orange Book-listed patents linked to IMVEXXY – a vaginal insert aimed at reducing pain during sexual intercourse after menopause.
Orange Book-listed patents are those approved by the U.S. Food and Drug Administration (FDA) and deemed safe to use.
The Australian drugmaker said it filed the lawsuit after a notification indicated Sun Pharma’s submission of an Abbreviated New Drug Application (ANDA) to the FDA to seek approval to market a generic version of IMVEXXY.
