Computer Sciences Corporation,

Plaintiff—Appellee,

Defendants—Appellants. ______________________________

Appeal from the United States District Court for the Northern District of Texas USDC No. 3:19-CV-970 ______________________________

Before Higginson, Ho, and Wilson, Circuit Judges. Stephen A. Higginson, Circuit Judge: Appellee Computer Sciences Corporation (“CSC”) sued Appellant Tata Consultancy Services Limited (“TCS”) for trade secret misappropriation under the Defend Trade Secrets Act of 2016, Pub. L. No. 114-153, § 2(a), 130 Stat. 376, 376–80 (codified at 18 U.S.C. § 1836). CSC alleged that TCS had used CSC’s trade secrets to win a $2.6 billion contract with non-party Transamerica and to develop TCS’s own software platform BaNCS. Following an eight-day trial with an advisory jury, the district court found TCS liable, ordered TCS to pay $56 million in compensatory damages Case: 24-10749 Document: 93-1 Page: 2 Date Filed: 11/21/2025

No. 24-10749

and $112 million in exemplary damages, and imposed a permanent injunction, barring TCS from using CSC’s trade secrets or the version of BaNCS that TCS developed using CSC’s trade secrets. TCS raises six issues on appeal: (1) whether the relevant contracts authorized TCS’s use of CSC’s confidential information1; (2) whether TCS acted with the requisite mens rea for misappropriation; (3) whether CSC defined its alleged trade secrets with sufficient specificity at trial; (4) whether the district court erred in awarding both unjust enrichment damages and a permanent injunction; (5) whether the exemplary damages award was excessive; and (6) whether the district court erred in imposing the injunction on non-parties. For the reasons below, we vacate the injunction and remand to the district court with instructions to issue a revised injunction, but we otherwise affirm the district court’s holdings. I. A. Plaintiff-Appellee CSC, an American multinational corporation, “provides information technology services and business solutions software to its customers, including customers in the life, wealth, and annuities industry.” Defendant-Appellant2 TCS is a “global company offering technology and consulting services to its customers, including customers in the insurance industry.” This case concerns two of CSC’s software

_____________________ 1 Because TCS challenges the district court’s trade secrets finding on appeal, we generally refer to this material as CSC’s “confidential information” when referencing the same material that the district court referred to as CSC’s “Trade Secrets” in the Findings of Fact and Conclusions of Law. 2 The district court held that “CSC did not present adequate proof of liability against” TCS’s co-defendant Tata America International Corp., a TCS subsidiary.

platforms, Vantage and CyberLife, and one of TCS’s software platforms, BaNCS. As summarized by the district court, Transamerica provides, through its subsidiaries, “life insurance, long-term care insurance, voluntary benefits, retirement plans, recordkeeping and advisory services, annuities, mutual funds, and other long-term savings and investment products to its customers.” In 1994, CSC entered into an agreement with a subsidiary of Transamerica, under which CSC licensed certain software to Transamerica. In 1999, CSC and Transamerica amended that licensing agreement to include CyberLife (the “CyberLife Agreement”). Similarly, in 1998, CSC entered into an agreement with Transamerica’s predecessor, under which CSC licensed certain software, and in 2005, CSC and Transamerica amended that licensing agreement to include Vantage (the “Vantage Agreement”). Both agreements authorize Transamerica to use and modify the software programs to benefit Transamerica. Both agreements also provide that CSC retains ownership over the software platforms and the confidential information therein, and that Transamerica may not use CSC’s confidential information to reverse engineer a platform for itself. In 2013, TCS and Transamerica entered into a Master Services Agreement (the “2013 Master Services Agreement”). Pursuant to that Agreement, Transamerica engaged TSC as a third-party consultant to provide maintenance services for Vantage and CyberLife. To facilitate this and other third-party work, Transamerica and CSC executed a Third-Party Access Addendum (the “Third-Party Addendum”) in February 2014. The Third-Party Addendum served as an addendum to existing licensing agreements and generally allowed Transamerica to authorize its consultants to access, copy, execute, use and modify CSC’s software “solely for the benefit” of Transamerica. TCS was one of the contractors that were specifically named in the Third-Party Addendum.

While providing maintenance services for Transamerica, TCS was also interested in finding an “anchor client” to facilitate its entrance into the U.S. insurance industry with its own software platform BaNCS. TCS describes BaNCS as having four “layers”: (1) the core layer, which “consists of foundational elements shared across all TCS BaNCS customers”; (2) the business layer, which “extends the data definitions for specific market segments”; (3) the geography layer, which “contains business processes for country- and state-specific rules and regulations, and product templates that provide insurers with a foundation for fully-compliant product launches”; and (4) the customer layer, which “acts as a repository for modifications specific to a single organization or business unit,” and is specifically at issue in TCS’s claims on appeal. See infra Section III.A.1. In 2016, Transamerica “decided its software needed a refresh, so it initiated a vendor-selection process.” Multiple vendors, including both TCS and CSC, submitted bids and conducted due diligence. At the time, TCS’s BaNCS software was not ready for use in the U.S. market as TCS was still building its U.S. “geography layer,” but TCS hoped that “landing Transamerica as an anchor client would create an opportunity to adapt BaNCS for the U.S. market.” In August 2017, TCS and Transamerica entered into Service Agreement No. 75 (“Service Agreement 75”) to the August 2013 Master Services Agreement to enable TCS’s due diligence. Service Agreement 75 required TCS to undertake a number of specific activities, including requiring TCS to: “[u]nderstand and validate [Transamerica’s] operational landscape, which includes its software”; “[v]alidate the Transition Plan for each line of business”; and produce a “Comprehensive Due Diligence Report,” a “[t]arget operating model for Transition Services and TPA Services,” and “[c]omplete and accurate Transition Plans for each line of business.” To facilitate this work, Service Agreement 75 obliged Transamerica to furnish TCS with “data” and other

4 Case: 24-10749 Document: 93-1 Page: 5 Date Filed: 11/21/2025

“required information.” The agreement did not assign TCS any role in assuring that information could be disclosed. TCS won the contract with its $2.6 billion bid. However, until TCS finished developing BaNCS for the U.S. market, it would continue to provide maintenance services for Transamerica’s policies on CSC’s platforms.
