Kolon wins in appeals court over DuPont in U.S. lawsuit

April 3, 2014

WASHINGTON (Yonhap) — A U.S. appeals court on Thursday overturned a 2012 verdict against Kolon Industries Inc. of South Korea that awarded DuPont Co. $919.9 million in damages.

DuPont, the largest U.S. chemical firm by market value, has alleged its South Korean rival stole some trade secrets for Kevlar, a fiber used to make tires, fiber-optic cables and bullet-proof vests.

In 2012, jurors in a federal court in Richmond, Va., delivered a verdict in favor of DuPont, ordering Kolon to pay $919.9 million.

But the 4th U.S. Circuit Court of Appeals in the city threw out the verdict, saying the judge wrongly excluded evidence related to Kolon’s defense. It ordered a new trial.

DuPont’s response was not immediately available.
