Breach of NDA

Parties can seek injunctive relief or damages if their protected information was disclosed. In Illinois, such legal action can be sought within ten years after the NDA was breached.[1]

If the breach involves trade secret misappropriation, legal action must be taken within five years of discovery.[2]

Trade Secret: Defined

Illinois law states that information is considered a trade secret if[3]:

  • It can derive economic value from not being known or easily reproducible.
  • It is being kept confidential by the owner.
