The Court of Appeals of Virginia on Tuesday reversed Appian Corp.'s $2 billion trade secrets judgment against competitor Pegasystems Inc., saying that the trial court made a series of errors on its way to the biggest jury award in state history and that a new trial was warranted. The trial court, Fairfax County Circuit Court, wrongfully allowed Appian to rely on Pegasystems' total sales over a certain period to prove unjust enrichment damages and then "improperly foreclosed" Pegasystems from showing that many of its total sales were in areas where the companies did not compete, a three-judge panel concluded unanimously. It also said the trial court erred in relieving Appian of its "proper burden to prove causation between the alleged misappropriation and any damages" through jury instruction.
