Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (2) disclosure or use of a trade secret of a person without express or implied consent by another person who:
    (A) used improper means to acquire knowledge of the trade secret; or
    (B) at the time of disclosure or use, knew or had reason to know that knowledge of the trade secret was:
    (I) derived from or through a person who utilized improper means to acquire it;
    (II) acquired under circumstances giving rise to a duty to maintain its secrecy or limit its use; or
    (III) derived from or through a person who owed a duty to the person seeking relief to maintain its secrecy or limit its use; or

765 ILCS 1065/3

    (765 ILCS 1065/3) (from Ch. 140, par. 353)
    Sec. 3. (a) Actual or threatened misappropriation may be enjoined. Upon application to the court, an injunction may be terminated when the trade secret has ceased to exist, provided that the injunction may be continued for an additional reasonable period of time in appropriate circumstances for reasons including, but not limited to an elimination of the commercial advantage that otherwise would be derived from the misappropriation, deterrence of willful and malicious misappropriation, or where the trade secret ceases to exist due to the fault of the enjoined party or others by improper means.
    (b) If the court determines that it would be unreasonable to prohibit future use due to an overriding public interest, an injunction may condition future use upon payment of a reasonable royalty for no longer than the period of time the use could have been prohibited.
    (c) In appropriate circumstances, affirmative acts to protect a trade secret may be compelled by a court order.

If neither damages nor unjust enrichment caused by the misappropriation are proved by a preponderance of the evidence, the court may award damages caused by misappropriation measured in terms of a reasonable royalty for a misappropriator's unauthorized disclosure or use of a trade secret.
    (b) If willful and malicious misappropriation exists, the court may award exemplary damages in an amount not exceeding twice any award made under subsection (a).
