Tennessee Code Title 47. Commercial Instruments and Transactions § 47-25-1707

An action for misappropriation must be brought within three (3) years after the misappropriation is discovered or, by the exercise of reasonable diligence, should have been discovered. For the purposes of this section, a continuing misappropriation by any person constitutes a single claim against that person, but this section shall be applied separately to any claim against each other person who receives a trade secret from another person who misappropriated that trade secret.
