(Corrects spelling of Sunovion in headline.)

Dainippon Sumitomo Pharma Co.’s Sunovion won an appeals court ruling today that Dr. Reddy’s Laboratories Ltd.’s generic version of Lunesta would infringe a patent that expires next year.

The U.S. Court of Appeals for the Federal Circuit in Washington said the trial judge erred in ruling the Dr. Reddy’s version didn’t infringe the patent. The opinion was posted on the court’s website.
