Texas Trade Secret Injunctions: The Real Trial

Several Texas appellate decisions have dissolved or narrowed trade secret injunctions based on the order’s wording rather than the strength of the proof. Rule 683 of the Texas Rules of Civil Procedure requires that an injunction set forth the reasons for its issuance, be specific in terms, and describe in reasonable detail—not by reference to the pleadings—the acts restrained. Those requirements are mandatory, and an order that fails to meet them may be declared void and dissolved.

So while a temporary injunction hearing decides many Texas trade secret cases, the resulting order undoes many of them.

What Butnaru Still Requires

Section 134A.003(a) says actual or threatened misappropriation “may be enjoined,” so long as the order does not prohibit a person from using general knowledge, skill, and experience acquired during employment. The verb is permissive, and no Texas Supreme Court decision holds that the statute relieves an applicant of what Butnaru v. Ford Motor Co., 84 S.W.3d 198, 204 (Tex. 2002), demands: a probable right to the relief sought, and a probable, imminent, and irreparable injury in the interim.

Texas courts of appeals have not settled whether irreparable injury is presumed. The Fort Worth Court of Appeals has said that “[t]he threatened disclosure of trade secrets constitutes irreparable injury as a matter of law.” IAC, Ltd. v. Bell Helicopter Textron, Inc., 160 S.W.3d 191, 200 (Tex. App.—Fort Worth 2005, no pet.). The First Court, sitting en banc two years earlier, treated the analogous prima facie presumption as rebuttable and not binding on the trial court, and declined to adopt inevitable disclosure at all. Cardinal Health Staffing Network, Inc. v. Bowen, 106 S.W.3d 230, 236, 241–43 (Tex. App.—Houston [1st Dist.] 2003, no pet.).

But a movant who relies on the presumption gives an appellate court a reason to dissolve the order and leaves the trial judge nothing to write down—and Rule 683 requires the judge to write something down.

The hearing does not decide whether the information is, in law and fact, a trade secret. The question is actually narrower: whether the applicant has shown the information is entitled to protection until trial. IAC, 160 S.W.3d at 197.

Who Gets to Sit in the Room?

Section 134A.006(b), added in 2017, presumes a party may participate and assist counsel, and lets the court exclude a party or its representative when countervailing interests overcome that presumption. The court must run a balancing test across seven listed considerations, including the value of the secret, the competitive harm disclosure would cause, and whether the representative acts as a competitive decision maker.

The Legislature wrote that provision a year after In re M-I L.L.C., 505 S.W.3d 569 (Tex. 2016), where a trial court refused to exclude a competitor’s designated representative from a temporary injunction hearing with the observation, “You sued them. They stay, period.” The Supreme Court conditionally granted mandamus—not because exclusion was required, but because the court had never performed the required balancing analysis. On the competitive decision-maker question, it borrowed the D.C. Circuit’s line that “it is very difficult for the human mind to compartmentalize and selectively suppress information once learned.”

Where Injunctions Die

Now to Rule 683, which produces more reversals in this area than the merits do.

In Wimbrey v. WorldVentures Marketing, LLC, No. 05-19-01520-CV (Tex. App.—Dallas Dec. 17, 2020, no pet.) (mem. op.), the Dallas court dissolved an injunction on two grounds. The order restrained disparagement without saying why. And it restrained use of “confidential information” without defining the term, leaving the defendants “to speculate about what particular information or item would constitute ‘confidential information.'”

In Reliant Hospital Partners, LLC v. Cornerstone Healthcare Group Holdings, Inc., 374 S.W.3d 488 (Tex. App.—Dallas 2012, pet. denied), the order was void as to one defendant because it drew no connection between the acts restrained and any irreparable injury attributable to him. A paragraph barring dealings with post-acute care facilities the defendants learned about while employed came out entirely because nothing in it limited the restraint to confidential information. The trial court had “essentially created a non-compete restriction.”

And in Contract Datascan Holdings, Inc. v. Retail Services WIS Corp., No. 02-23-00153-CV (Tex. App.—Fort Worth Nov. 16, 2023, no pet.) (mem. op.), five paragraphs fell because the order’s definition of confidential information swept in the plaintiff’s whole client list when the evidence concerned a single client. The court quoted the appellant’s framing with approval: “The universe of WIS’s clients is known only to WIS, so Datascan is left only to guess.”

But the tension is real, and nobody has resolved it. Rule 683 requires describing the restrained conduct in reasonable detail, while case law tells courts to word these orders so they do not disclose the secret. Rugen v. Interactive Business Systems, Inc., 864 S.W.2d 548, 553 (Tex. App.—Dallas 1993, no writ). Describe the information by source and category rather than content—the pricing model given to a named customer in a named month, the drawings for a named part number.

And Rule 683 requires the order to set the case for trial, which does more than housekeeping. In Wimbrey, the non-solicitation restraint tracked a one-year contractual limit that expired while the appeal was pending, and the issue went moot. A short contractual restraint and a distant trial setting cancel each other out—one reason the enforcement questions in our discussion of Texas non-compete agreements in post-employment disputes belong in the injunction strategy from the start.

Sealing After September 2025

In HouseCanary, Inc. v. Title Source, Inc., 622 S.W.3d 254 (Tex. 2021), the Supreme Court held that the Texas Uniform Trade Secrets Act displaces parts of Rule 76a but supplies no self-contained sealing pathway. Effective September 1, 2025, House Bill 4081 added section 134A.0065: a notice-and-affidavit procedure, a right in any person to move to unseal, and a preponderance burden on the claimant to show the document holds actual secrets. The Business Court gave a related lesson two months earlier. In SafeLease Insurance Services, LLC v. Storable, Inc., 2025 Tex. Bus. 28, the defendant lost the Rule 507 trade secret privilege because it never asserted it in its discovery responses, as Rule 193.3(a) requires. The customer list was produced.

The order is the deliverable in a Texas trade secret injunction practice. Draft it before the hearing, include the reasons, get the trial setting, and describe what it restrains so narrowly that the person bound by it never has to guess.
