S.C. Code Ann. § 39-8-100
(A) If the court finds that a trade secret may be disclosed during a criminal proceeding, the court must issue a protective order limiting the use and dissemination of the trade secret including, but not limited to, articles disclosing that secret, provided that the issuance of a protective order would not conceal fraud or work an injustice. The protective order may, in the court's discretion, include the following provisions:
(3) that a party seeking to show the trade secret, or articles containing the trade secret, to a person not designated by the protective order must first obtain court approval to do so.
