A federal appeals court has overturned a jury decision awarding $920 million in damages to the DuPont Co. in a trade-secrets lawsuit involving high-strength synthetic fibers used in products such as Kevlar body armor.
The appeals court in Richmond, Va., said Thursday that a trial judge abused his discretion and prejudiced South Korea-based Kolon Industries in 2011 when he granted a pretrial motion by DuPont. The court said that in doing so, the judge excluded evidence material to Kolon's defense.
