Trade Secret Protection for Texas Businesses: What Qualifies, What You Must Do to Keep It, and What Happens When Someone Takes It

By Hank FasthoffJuly 6, 2026

A trade secret is the one form of intellectual property that a single disclosure can destroy in an instant, with nothing you or any court can do to get it back. A patent expires 20 years from filing and, as long as maintenance fees are paid, stays enforceable no matter how widely the holder discloses the invention. A trademark can last indefinitely as long as it's used in commerce and renewed. A copyright lasts the author's life plus 70 years without any maintenance obligation. A trade secret lasts only as long as the owner keeps it secret. Once the information becomes generally known, no court can restore the protection. The secret is gone, and so is the competitive advantage it provided.

For many businesses, trade secrets are the most economically valuable IP they own. Customer lists, pricing models, manufacturing processes, supplier relationships, proprietary formulas, software algorithms, marketing strategies, and business plans all qualify if two conditions are met: the information derives independent economic value from not being generally known, and the owner takes reasonable measures to maintain its secrecy. If either condition fails, the information isn't a trade secret and isn't protectable.

What Qualifies as a Trade Secret

Under the Texas Uniform Trade Secrets Act (TUTSA), codified at TCPRC Chapter 134A, a trade secret is defined as all forms and types of information, including business, scientific, technical, economic, or engineering information, and any formula, design, prototype, pattern, plan, compilation, program device, program, code, device, method, technique, process, procedure, financial data, or list of actual or potential customers or suppliers, if the owner has taken reasonable measures under the circumstances to keep the information secret and the information derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable through proper means by, another person who can obtain economic value from the disclosure or use of the information. TCPRC § 134A.002(6).

Federal protection under the Defend Trade Secrets Act (DTSA), 18 U.S.C. § 1836, provides a parallel cause of action using a substantially identical definition. The DTSA requires that the trade secret be "related to a product or service used in, or intended for use in, interstate or foreign commerce," which limits its scope to businesses with interstate commercial activity. TUTSA has no such limitation.

Texas courts evaluate trade secret status using six factors: how extensively the information is known outside the business, how extensively it's known within the business, what measures the owner took to guard its secrecy, the value of the information to the owner and to competitors, the amount of effort or money the owner spent developing the information, and the ease or difficulty with which the information could be properly acquired or duplicated by others.

Not every piece of confidential business information qualifies. General knowledge, skill, and experience that an employee acquires during employment aren't trade secrets, even if the employee learned them on the job. Industry-standard practices and publicly available data aren't trade secrets regardless of how the owner labels them. And information that the owner treats carelessly (sharing it without NDAs, leaving it accessible to anyone in the organization, failing to mark it confidential) may lose its protected status because the "reasonable measures" requirement wasn't met.

Reasonable Measures to Maintain Secrecy

Reasonable measures are where most trade secret claims succeed or fail. Texas courts won't protect information that the owner didn't bother to protect. What constitutes "reasonable" depends on the circumstances, but courts consistently look for several categories of safeguards.

Confidentiality agreements (NDAs) should be signed by every employee, independent contractor, vendor, and business partner who has access to the information. An NDA that specifically identifies the categories of confidential information, restricts disclosure and use, and survives the termination of the relationship is the foundation of any trade secret protection program.

Access controls limit who can view, copy, or transmit the information. Physical controls include locked offices, restricted-access areas, and visitor sign-in procedures. Electronic controls include password-protected files, encrypted storage, role-based access permissions, and access logs that track who viewed what and when.

Confidential markings on documents, emails, presentations, and files containing trade secret information signal to everyone who encounters them that the material is protected. "Confidential," "Trade Secret," or "Proprietary" markings aren't sufficient by themselves, but their absence makes it harder to prove that the owner treated the information as secret.

Need-to-know policies restrict access to trade secret information to employees and contractors who require it for their job functions. If every employee in the organization has access to the customer list, it's harder to establish that the customer list was subject to reasonable protection. If only three people in the sales department have access, the claim is much stronger.

Exit procedures for departing employees are critical because the most common trade secret disputes involve employees who leave and take information with them (or retain it in their memory). Exit procedures should include a return-of-property protocol (collecting laptops, phones, files, access badges, and any copies of confidential information), a reminder of the departing employee's confidentiality obligations under the NDA, revocation of electronic access on or before the last day of employment, and a brief exit interview documenting the employee's acknowledgment that confidential information must not be used in future employment.

Misappropriation

Misappropriation under TUTSA occurs when a trade secret is acquired by improper means (theft, bribery, misrepresentation, breach of a duty to maintain secrecy, or espionage, including electronic espionage), or when a trade secret is disclosed or used without consent by someone who knew or should have known that the information was acquired through improper means or in violation of a confidentiality obligation. TCPRC § 134A.002(3).

Reverse engineering (starting with a lawfully obtained product and working backward to determine how it was made) isn't misappropriation, unless a contract such as a license term prohibits it. Independent development (creating the same information independently without reference to the trade secret) isn't misappropriation. These are "proper means" under the statute, and a trade secret owner can't prevent a competitor from reaching the same result through legitimate effort.

Most misappropriation disputes involve a departing employee who takes confidential files, customer lists, or proprietary data to a competitor. The second most common involves a business partner or vendor who uses confidential information received under an NDA for purposes outside the scope of the agreement. In both cases, the owner's ability to prove misappropriation depends heavily on the documentation of reasonable measures taken before the misappropriation occurred.

The Inevitable Disclosure Doctrine

Inevitable disclosure is a theory under which a court may enjoin a departing employee from working for a competitor on the grounds that the employee's knowledge of trade secrets makes it "inevitable" that the employee will disclose or use those secrets in the new position, even without evidence of actual disclosure.

Texas courts have given the inevitable disclosure doctrine limited acceptance. TUTSA allows injunctions for "threatened misappropriation," but the statute specifies that an injunction can't prohibit a person from using "general knowledge, skill, and experience" acquired during prior employment. TCPRC § 134A.003(a). The DTSA goes further, stating that an injunction can't "prevent a person from entering into an employment relationship" and can only place conditions on employment based on "evidence of threatened misappropriation." 18 U.S.C. § 1836(b)(3)(A).

In practice, a Texas court is unlikely to block an employee from working for a competitor solely because the employee knows trade secrets. The owner typically must show more: that the employee took documents or data, that the employee's new role would specifically require use of the trade secrets, or that the employee made statements suggesting an intent to use the information. Inevitable disclosure alone, without additional evidence of threatened misappropriation, is generally insufficient in Texas.

Remedies

TUTSA and the DTSA provide three categories of remedies for trade secret misappropriation.

Injunctive relief prevents the continued or threatened use of the trade secret. A court can issue a temporary restraining order (often sought on an emergency basis when the owner discovers the misappropriation), a temporary injunction (maintaining the status quo during litigation), and a permanent injunction (entered after trial). TUTSA also creates a statutory presumption in favor of granting protective orders during litigation to preserve the secrecy of the alleged trade secret. TCPRC § 134A.006(a).

Monetary damages can include actual loss caused by the misappropriation (lost profits, lost customers, diminished competitive position), unjust enrichment not accounted for in the actual loss calculation (the profits the defendant earned by using the misappropriated information), or a reasonable royalty for the unauthorized use (an alternative measure when actual loss and unjust enrichment are difficult to calculate).

Exemplary damages of up to twice the compensatory award are available if willful and malicious misappropriation is proven under the clear and convincing evidence standard the statute requires. TCPRC § 134A.004(b). Attorney's fees may be awarded to the prevailing party if the misappropriation was willful and malicious or if the claim was brought in bad faith. TCPRC § 134A.005. The statute of limitations is three years from the date the misappropriation was discovered or should have been discovered through reasonable diligence.

DTSA Whistleblower Immunity Notice

Under the DTSA, employers must include a specific immunity notice in any contract or agreement that governs the use of trade secrets or other confidential information. The notice must inform employees and contractors that they're immune from criminal or civil liability under federal or state trade secret law for disclosing a trade secret in confidence to a government official or attorney for the purpose of reporting a suspected violation of law, or for disclosing a trade secret in a complaint or other document filed under seal in a lawsuit. 18 U.S.C. § 1833(b).

If the employer fails to include this notice and later sues the employee for misappropriation under the DTSA, the employer can't recover attorney's fees or exemplary damages. The notice requirement applies to contracts entered into or updated after the DTSA's enactment in May 2016.

Practical Recommendations

Identify your trade secrets before a dispute forces you to. Many businesses can't articulate what their trade secrets are until someone takes them. Document the information that provides competitive value, explain why it's not generally known, and record the measures you've taken to protect it.

Require NDAs from every person who accesses trade secret information. Employees, independent contractors, vendors, joint venture partners, potential investors conducting due diligence, and anyone else who receives confidential information should sign an NDA before receiving access.

Implement electronic access controls that restrict access to trade secret information on a need-to-know basis. Use password protection, encryption, role-based permissions, and access logs. If you can't identify who accessed a file and when, you'll have difficulty proving misappropriation.

Conduct exit procedures for every departing employee. Collect all company property and copies of confidential information, revoke electronic access, and remind the employee of their ongoing confidentiality obligations in writing.

Include the DTSA whistleblower immunity notice in every NDA, employment agreement, and contractor agreement. Omitting it forfeits your right to recover attorney's fees and exemplary damages under the DTSA.

If you discover misappropriation, act immediately. Trade secret protection is time-sensitive. Delay in seeking an injunction can be interpreted as evidence that the information isn't valuable enough to protect, and continued dissemination of the information can destroy the trade secret status entirely. Contact your attorney the day you discover the misappropriation, not the week after.
