Noven Pharmaceuticals, Inc. said it filed a lawsuit in the US District Court of Delaware against Alvogen for patent infringement.
Noven said Alvogen is seeking approval to market and sell a generic version of its estrogen therapy patch Minivelle (estradiol transdermal system) prior to the expiration of two of Noven’s Orange Book listed patents.
“The lawsuit reflects Noven’s commitment to vigorously enforce its intellectual property rights against infringement,” said Noven.
Noven’s general counsel Michael Greene said: “Minivelle is Noven’s premier commercialized product.
“We are confident in the strength of our patent position and it is our intent to aggressively protect Minivelle and our intellectual property.”
