LexMachina has released a new report on Trade Secret litigation in Federal Court.
The basics: Federal Trade Secret litigation is up about 30% following enactment of the Defend Trade Secrets Act (DTSA) in 2016. (1134 cases filed in 2017). The DTSA created a federal cause of action for trade secret litigation and resulting original jurisdiction in federal court for the federal claims. Prior to the DTSA, state-law trade secret claims found their way into federal court either via supplemental jurisdiction (typically linked to an a federal IP claim) or via diversity jurisdiction (parties from different states).
The vast majority of trade secret actions include additional causes of action — most often breach of contract or other commercial law claim.
