(Bloomberg) -- Teva Pharmaceutical Industries Ltd. lost an appeals court bid to revive four patents on its top-selling multiple sclerosis drug Copaxone.

A trial judge was correct to invalidate the four Teva patents, the U.S. Court of Appeals for the Federal Circuit said Friday in an opinion on its electronic docket. The decision was a victory for generic-drug makers including Mylan NV and Novartis AG’s Sandoz.
