(j)An order granting or denying a motion to unseal a document under Subsection (h) is considered to be severed from the action and is a final judgment that may be appealed by any party or intervenor who participated in the hearing preceding the issuance of the order.

Plain-English Summary

A detailed filing procedure, and it covers the case where the secret belongs to someone who is not a party.

Subsection (a) — sealing your own secret. File a notice of sealing and an affidavit describing the type of information, giving contact details for later notice, and setting forth the factual basis for the trade secret allegation; deliver the document in a sealed envelope; and serve notice, affidavit and document on each other party.

Subsection (b) — filing someone else’s secret. A party filing a document it knows another person claims as a trade secret files a notice and a statement identifying that person, and must serve the non-party claimant as well as the parties.

Subsection (c) puts a 14-day clock on that non-party. They must file their own affidavit not later than the 14th day after receiving the notice.

Subsection (d) is what happens meanwhile, and the default is unforgiving. The document is treated as filed under seal until the 14 days expire — and if no affidavit is timely filed, it is treated as publicly filed until one is.

So a trade secret owner who misses the deadline loses the seal by default, and regains it only prospectively.

Subsection (f) gives any person a right to intervene — as a matter of right, before or after judgment — to seal or unseal, which matters when a secret reaches the public record in a case its owner knew nothing about.

Subsection (h) sets the unsealing standard: the court shall grant the motion unless the claimant shows by a preponderance of the evidence that the document contains a trade secret, with 14 days’ notice by certified mail. Subsection (j) makes the ruling severed and immediately appealable.

Subsection (k) was repealed effective December 4, 2025.
