Computer Sciences Corp. v. Tata: Trade Secrets

The Fifth Circuit affirmed a $168 million trade-secret judgment against Tata, endorsing unjust-enrichment damages based on the development costs a misappropriator avoided.

A nine-figure judgment over insurance software gave the Fifth Circuit a chance to clarify one of the most practically important questions in trade-secret remedies: can a plaintiff recover the costs a misappropriator avoided by stealing rather than building? In Computer Sciences Corp. v. Tata Consultancy Services Ltd., No. 24-10749 (5th Cir. Nov. 21, 2025), the court answered yes, affirming roughly $168 million in damages and endorsing unjust enrichment measured by avoided development costs. The decision is a modern marquee application of the value-based damages tradition, and it lands at a moment when courts are policing how aggressively trade-secret plaintiffs can monetize a defendant’s shortcut.

At a glance

Case: Computer Sciences Corp. v. Tata Consultancy Services Ltd., No. 24-10749 (5th Cir. Nov. 21, 2025).
Court: United States Court of Appeals for the Fifth Circuit, on appeal from the Northern District of Texas.
Posture: Appeal from a judgment entered after an eight-day trial with an advisory jury; the district court reduced the jury’s recommended awards before entering judgment.
Holding: The court affirmed roughly $168 million in damages, upheld findings of unauthorized, willful and malicious misappropriation, and endorsed unjust-enrichment damages based on avoided development costs; it vacated the injunction and remanded for a narrowed one.
Significance: Confirms that avoided-cost unjust enrichment is a recoverable measure under the DTSA, even absent harm beyond the plaintiff’s actual losses. The Supreme Court denied certiorari on June 15, 2026 (No. 25-1107), leaving the rule in place.

The platforms and the consultant

Computer Sciences Corporation (CSC) licensed two insurance software platforms (Vantage and CyberLife) to the insurer Transamerica. Tata Consultancy Services (TCS), a global technology consultancy, was later brought in by Transamerica as a third-party vendor to maintain those CSC platforms. That arrangement gave TCS authorized access to CSC’s confidential material for a limited, defined purpose.

TCS, however, was developing its own competing insurance platform, BaNCS, and won a multibillion-dollar contract to migrate Transamerica’s business onto it. The evidence at trial showed that TCS used CSC’s confidential information, including source code and technical manuals, in building out BaNCS. In other words, access granted for maintenance was, the factfinder concluded, exploited to accelerate a competing product. CSC sued in the Northern District of Texas in August 2019, pleading among other claims a trade-secret misappropriation claim under the federal Defend Trade Secrets Act. (Texas law governed CSC’s contracts with Transamerica; New York law governed TCS’s.)

Unauthorized use and a willful, malicious finding

After an eight-day trial with an advisory jury, the district court found for CSC. It concluded that TCS’s use exceeded the authorization in the governing contracts and that TCS acted with the requisite mental state, including willful and malicious misappropriation (the predicate for exemplary damages). The court reduced the jury’s recommended compensatory award to $56 million and its exemplary award to $112 million, for a total of roughly $168 million.

On appeal, the Fifth Circuit affirmed those liability findings. It agreed that the contracts did not permit TCS to repurpose CSC’s confidential material for BaNCS development, and that the record supported the willful-and-malicious determination. That mens rea finding is what unlocked the exemplary component, and the court affirmed the ratio between compensatory and exemplary damages as within permissible bounds.

Avoided development costs as the damages engine

The most consequential holding concerns how the compensatory damages were measured. The Fifth Circuit affirmed that a trade-secret plaintiff may recover unjust-enrichment damages based on the development costs the defendant avoided by misappropriating the secret. The logic is straightforward: when a defendant skips the time and expense of building technology independently and instead takes a shortcut through another’s secret, the benefit it gains is itself a recoverable measure of enrichment.

Critically, the court held this measure is available even absent harm to the plaintiff beyond its actual losses. A defendant’s enrichment can be a freestanding basis for damages; the plaintiff need not show that the misappropriation cost it additional sales or market share on top of what it already proved. That framing aligns the DTSA with the older value-to-the-defendant tradition in the Fifth Circuit, which since University Computing Co. v. Lykes-Youngstown Corp., 504 F.2d 518 (5th Cir. 1974), has measured the value of the secret to the defendant where the plaintiff cannot prove specific injury, and gives plaintiffs a powerful theory in cases where a sophisticated competitor uses stolen know-how to leapfrog development.

What Tata won and what remains

TCS did secure partial relief. The Fifth Circuit vacated the injunction and remanded for the issuance of a revised one, holding that a prohibition on TCS’s future use of “Post-Misappropriation BaNCS Material” overlapped with the unjust-enrichment award and had to be removed, while the bar on TCS’s access to and use of CSC’s trade secrets stayed. It also directed the district court to clarify the definition of the parties bound so the injunction comports with Federal Rule of Civil Procedure 65(d)(2). The damages, however, stood: the court otherwise affirmed on all remaining issues. TCS sought certiorari, and on June 15, 2026, the Supreme Court denied review in Tata Consultancy Services Ltd. v. Computer Sciences Corp., No. 25-1107, leaving the Fifth Circuit’s rule intact.

Open questions

How far does avoided-cost enrichment extend? The decision endorses the measure but leaves room to argue about how to quantify avoided costs and isolate them from a defendant’s legitimate independent work.
What is the ceiling on exemplary ratios? The court affirmed this ratio, but the boundaries of permissible exemplary multiples in trade-secret cases remain fact-dependent.
Will the circuit split be resolved? Not soon. The Fifth Circuit expressly declined to follow the general rule announced in the Second Circuit’s Syntel Sterling Best Shores Mauritius Ltd. v. TriZetto Group, 68 F.4th 792 (2d Cir. 2023), that a secret holder can never recover unjust-enrichment damages where it suffers no compensable harm beyond lost profits. With certiorari denied on June 15, 2026, the disagreement persists and the answer depends on where suit is filed.

Implications

Avoided cost is a recoverable benefit. Plaintiffs can frame damages around what the defendant saved by not building the technology itself, not just the plaintiff’s lost profits.
No separate harm requirement for enrichment. A defendant’s gain can ground damages even without proof of incremental harm beyond actual losses already shown.
Authorized access is not a safe harbor. Vendors granted access for one purpose face serious exposure if they repurpose confidential material to build competing products.
Willful and malicious findings drive exemplary exposure. The mental-state finding more than doubled the award; defendants should treat intent evidence as outcome-determinative.
Injunctions must avoid double recovery. Courts will trim injunctive terms that duplicate damages and must define bound parties with Rule 65 precision.

Frequently asked questions

What did the Fifth Circuit decide in Computer Sciences Corp. v. Tata? It affirmed a roughly $168 million trade-secret judgment, including $56 million in compensatory damages and $112 million in exemplary damages, and upheld findings that Tata’s use of CSC’s confidential material was unauthorized and willful and malicious.

How were the damages measured? Largely through unjust enrichment based on avoided development costs. The court held a trade-secret plaintiff may recover the benefit a defendant gained by skipping the cost of independently developing the technology, even absent additional harm to the plaintiff beyond its actual losses.

Did Tata win anything on appeal? Partly. The Fifth Circuit vacated the injunction and remanded for a narrowed one, removing the bar on Tata’s future use of post-misappropriation BaNCS material as duplicative of the damages award and directing the district court to clarify who was bound under Federal Rule of Civil Procedure 65(d)(2). It otherwise affirmed, and the Supreme Court denied certiorari on June 15, 2026 (No. 25-1107).
