The US Supreme Court has sided with Teva Pharmaceutical Industries Ltd. in the company's high-profile patent dispute with rival firms over the top-selling multiple sclerosis drug.
The justices ruled Tuesday that a federal appeals court wrongly overturned five of Teva's patents for the drug Copaxone. The decision allows the Israel-based company to keep its exclusive rights to the drug until September 2015. Copaxone generates about $4 billion in annual sales for Teva.
