Texas Unfair Competition Law: Prohibited Conduct, Damages, and Deadlines

Texas unfair competition law is an umbrella covering several distinct causes of action: trademark infringement, trade secret misappropriation, violations of the Deceptive Trade Practices Act, tortious interference with contracts or prospective business, and breaches of enforceable non-compete agreements. Each has its own elements, deadlines, and damages rules, but they share a common premise: competing hard is legal, while competing through deception, theft, or interference is not. A successful plaintiff can recover actual losses, and in the right cases, multiplied damages, exemplary damages, injunctions halting the conduct, and attorney fees.

What Counts as Unfair Competition in Texas

Trademark Infringement

Using another company’s name, logo, or identifying mark without permission is one of the clearest forms of unfair competition. Under the Texas Trademark Act, anyone who uses a reproduction or imitation of a registered mark in connection with selling goods or services can be held liable if the use is likely to confuse consumers about the source, even if no actual confusion has yet occurred.¹ The statute does not displace common law trademark rights, so businesses that built goodwill in a mark before registration still retain those protections.²

Trade Secret Misappropriation

The Texas Uniform Trade Secrets Act (TUTSA) protects confidential business information from being stolen, leaked, or used without authorization. A trade secret is any information that derives economic value from not being publicly known, provided the owner took reasonable steps to keep it secret. That includes formulas, customer lists, software code, financial data, and manufacturing processes.³

Misappropriation covers two scenarios: acquiring a trade secret through improper means like theft, bribery, or breach of a confidentiality agreement, or disclosing or using someone else’s trade secret when you know or should know it was improperly obtained. TUTSA also carves out “proper means,” which expressly includes independent development and reverse engineering unless a contract prohibits it.³

Deceptive Trade Practices

The Texas Deceptive Trade Practices-Consumer Protection Act (DTPA) declares false, misleading, or deceptive acts in trade or commerce to be unlawful, and lists dozens of specific prohibited acts, including misrepresenting a product’s quality, characteristics, or geographic origin, and falsely claiming sponsorship or affiliation that doesn’t exist.⁴ The DTPA is primarily a consumer protection statute, so individual consumers have access to the enhanced remedies described below. Businesses can bring DTPA claims in certain situations, but their access to the full remedy stack is more limited.

Tortious Interference

Texas common law prohibits intentionally disrupting another company’s existing contracts or prospective business relationships. To win a claim involving an existing contract, you must show four things: a contract existed, the defendant willfully and intentionally interfered with it, that interference proximately caused injury, and actual damages resulted. For claims involving prospective business relationships that hadn’t been finalized yet, you must also prove the defendant used independently wrongful conduct such as fraud, threats, or illegal activity.

Federal Law Running Alongside

Many Texas unfair competition disputes also implicate the federal Lanham Act, which creates civil liability for using a false designation of origin or making a misleading representation about goods or services in interstate commerce where the use is likely to confuse consumers about source, sponsorship, or affiliation. The Lanham Act also reaches false advertising in commercial promotion.⁵ You can bring state and federal unfair competition claims in the same lawsuit, and Texas state courts can hear Lanham Act claims that arise alongside state-law causes of action.

Non-Competes as a Separate Flashpoint

Non-compete agreements generate a large share of Texas unfair competition disputes, usually when an employee leaves for a competitor or starts a rival business. Texas enforces non-competes, but only if they meet specific requirements. The agreement must be tied to an otherwise enforceable deal, such as an employment contract that includes access to trade secrets or specialized training, and the limits on time, geography, and the scope of restricted activity must be reasonable and no broader than needed to protect the employer’s legitimate interests.⁶

What counts as reasonable depends on the facts. A two-year non-compete covering the same metropolitan area where the employee worked may be fine; a five-year ban covering the whole state probably isn’t. If a court finds the restrictions overly broad, Texas law allows the court to reform the agreement by narrowing it to enforceable terms rather than throwing it out entirely. Physicians have additional statutory protections, including guaranteed access to patient lists and the right to continue treating patients through an acute illness after leaving a practice.⁶

Proving a Claim

Specific elements vary by claim, but every unfair competition case in Texas shares a common backbone: you must show the defendant engaged in wrongful conduct that goes beyond ordinary competition, and that the conduct caused you measurable harm. Courts draw a firm line between aggressive-but-lawful tactics and conduct that crosses into deception, fraud, or misappropriation.

Causation is where many claims fall apart. You need a direct, provable link between the wrongful act and your losses. If a competitor spread false information and you lost customers, you need evidence that the misinformation actually drove those customers away, not that sales happened to dip during the same period. Speculation about lost revenue does not survive summary judgment.

Trade secret claims add a threshold hurdle: you have to prove the information qualifies as a trade secret at all. That means showing both that the information has independent economic value because it isn’t publicly known and that you took reasonable precautions to keep it secret.³ Companies that store sensitive data on unprotected shared drives, skip password protection, or never require nondisclosure agreements undermine their own claims before litigation starts.

What You Can Recover

Actual Damages

A plaintiff who wins can recover actual damages, including lost profits, diminished market share, and harm to business reputation. Courts expect financial records and expert testimony to quantify these losses. Vague assertions about reputational damage will not carry the day without supporting data.

Trade Secret Damages Under TUTSA

TUTSA provides its own damages framework. You can recover actual losses caused by the misappropriation plus any unjust enrichment the defendant gained that isn’t already captured in the loss calculation. When losses are hard to quantify, the court can instead impose a reasonable royalty based on what the defendant should have paid for authorized use of the trade secret.⁷

For willful and malicious misappropriation proven by clear and convincing evidence, TUTSA allows exemplary damages up to twice the amount awarded under the actual-damages calculation.⁷ This cap sits separately from the general exemplary damages cap below.

DTPA Damages

The DTPA has its own multiplier for bad actors. A prevailing consumer recovers economic damages as a baseline. If the defendant acted knowingly, the consumer can also recover mental anguish damages, and the court can award up to three times the economic damages. If the defendant acted intentionally, the multiplier goes up: up to three times the combined total of economic damages and mental anguish damages. Attorney fees, court costs, and prejudgment interest are not folded into the base amount.⁸

General Exemplary Damages

For unfair competition claims outside TUTSA and the DTPA, Texas allows exemplary (punitive) damages when the plaintiff proves by clear and convincing evidence that the harm resulted from fraud, malice, or gross negligence.⁹ Texas caps these awards at the greater of $200,000 or two times the economic damages plus any noneconomic damages found by the jury, with the noneconomic portion itself capped at $750,000.¹⁰

Injunctive Relief

Courts can order a defendant to stop the unfair conduct. Injunctions are especially critical in trade secret cases, where ongoing use of stolen information causes damage that money alone cannot fix. Depending on urgency, a court may issue a temporary restraining order to halt the behavior immediately, a preliminary injunction to maintain the status quo during litigation, or a permanent injunction after final judgment. A temporary restraining order typically requires showing irreparable harm without it and a probable right to recover on the merits.

Attorney Fees

Fee recovery is not automatic in most Texas unfair competition cases, but two statutes create meaningful exceptions. Under TUTSA, the court may award reasonable attorney fees to the prevailing party if a misappropriation claim was brought in bad faith, if a motion to end an injunction was made or opposed in bad faith, or if willful and malicious misappropriation is established.¹¹ This cuts both ways: a defendant who proves a trade secret claim was filed frivolously can recover defense costs.

Under the DTPA, every prevailing consumer is entitled to court costs and reasonable attorney fees as a matter of right. If the court finds the DTPA lawsuit was groundless or brought in bad faith, the defendant gets its attorney fees instead.⁸ This built-in fee-shifting discourages both frivolous claims and meritless defenses.

Filing Deadlines

Missing a filing deadline kills a claim regardless of its merits. The deadlines vary by claim type, and they are shorter than many businesses expect.

DTPA claims: two years from the date the deceptive act occurred, or two years from the date you discovered or reasonably should have discovered the violation. If the defendant deliberately concealed the wrongdoing, the deadline can be extended by 180 days.¹²
Trade secret claims: three years from the date the misappropriation was discovered or should have been discovered through reasonable diligence. Ongoing misappropriation is treated as a single act for limitations purposes, so the clock starts once you learn of the initial theft.
Trademark claims: four years, borrowed from the Texas limitations period for fraud, applied to both state and federal infringement claims.
Tortious interference: generally two years, under the limitations period for intentional torts.

The discovery rule can stretch these deadlines when the wrongful conduct was inherently difficult to detect, but courts apply it narrowly. Waiting because you weren’t sure about the strength of your case is not the same as being unable to discover the violation.

Where Cases Are Filed and Who Else Can Sue

Unfair competition claims in Texas are filed in state district courts, which have general jurisdiction over civil business disputes. If the case involves a federal trademark claim under the Lanham Act or a trade secret claim under the federal Defend Trade Secrets Act, you can file in federal court, or remove the case there if the defendant was first sued in state court. The Texas Attorney General’s consumer protection division can pursue DTPA violations separately from any private lawsuit, which matters when the deceptive conduct affects a wider pool of consumers than any one plaintiff.⁴

The plaintiff carries the burden throughout. For most claims, that is a preponderance of the evidence; for exemplary damages, it rises to clear and convincing evidence of fraud, malice, or gross negligence.⁹ Successful plaintiffs can walk away with monetary damages, injunctive relief, or both.
