Pfizer Inc., the world’s largest drugmaker, convinced a U.S. judge that its patents for the pain-drug Lyrica are valid and infringed, giving it exclusive sales rights until 2018.
Pfizer, based in New York, sued competitors including Teva Pharmaceuticals USA in federal court in Wilmington, Delaware, in April 2009, contending their sales of generic Lyrica would infringe the patents and cause irreparable harm.
“The defendants are enjoined, based on this infringement, from commercially manufacturing, using, offering for sale, or selling” their product, and the U.S. Food and Drug Administration is prohibited from approving the generic drug applications until the patents expire, U.S. District Judge Gregory M. Sleet wrote in a 133-page opinion released yesterday.
“The court’s decision recognizes the infringement and validity of our Lyrica patents and affirms the value of Lyrica as a distinct and important innovation for patients,” Amy Schulman, Pfizer’s general counsel, said in a statement. “Protecting our intellectual property is vital to our ability to develop new medicines that save and enhance patients’ lives.”
Lyrica, approved by the FDA in 2004 to treat pain, also has been used by doctors to treat anxiety, epilepsy and restless-leg syndrome. Pfizer logged $3.7 billion in Lyrica sales last year.
