South Korean company Kolon Industries Inc. has asked the U.S. Fourth Circuit appellate court to overturn a lower court’s ruling and to side with Kolon in charges that competitor DuPont restricted competition. The initial ruling in September 2011 ruled against Kolon’s charges that DuPont created a monopoly on body armor fiber sales through market domination and price discrimination. Kolon argues that the Virginia federal court, who ruled against them, overlooked key evidence in the case.
