The Appian vs. Pega lawsuit no longer carries the $2.036 billion judgment a Virginia jury handed down in 2022. On January 8, 2026, the Supreme Court of Virginia affirmed an earlier appellate decision that vacated the award, and the trade secret case between Appian Corporation and Pegasystems Inc. has been sent back to the Circuit Court of Fairfax County for a new trial.1Justia. Appian Corp. v. Pegasystems Inc.2Justia. Pegasystems Inc. v. Appian Corp.
What Appian Accused Pegasystems of Doing
Appian alleged that Pegasystems used a third-party intermediary to access proprietary information about its low-code development platform. At the center of the claims was Youyong Zou, a software developer employed by Serco, a government contractor and Appian business partner. Through his Serco role, Zou had authorized access to Appian’s internal software environment and product documentation.1Justia. Appian Corp. v. Pegasystems Inc.
According to Appian, Pegasystems used that channel to view technical information that competitors could not see, and then applied what it learned to product development and sales strategy. Internal Pegasystems communications reportedly referred to the consultant as a spy who helped the company pressure-test its rival’s technology. In some presentations, Pega leadership reportedly blurred the consultant’s name in videos to hide his identity.1Justia. Appian Corp. v. Pegasystems Inc.
Appian argued that this access let Pegasystems identify weaknesses in the Appian platform to exploit in sales meetings while replicating its strengths in Pega’s own product.1Justia. Appian Corp. v. Pegasystems Inc.
The 2022 Jury Verdict
After a seven-week trial in 2022, the jury found that Pegasystems had misappropriated trade secrets under the Virginia Uniform Trade Secrets Act and had violated the Virginia Computer Crimes Act. Damages under the Computer Crimes Act were set at $1. The trade secret claim drove the total judgment to $2.036 billion.2Justia. Pegasystems Inc. v. Appian Corp.1Justia. Appian Corp. v. Pegasystems Inc.
Pegasystems challenged the award immediately, arguing that the damages were excessive and that the legal standards for proving misappropriation had not been met.2Justia. Pegasystems Inc. v. Appian Corp.
Why the Judgment Was Vacated
On July 30, 2024, the Court of Appeals of Virginia vacated the judgment, and the Supreme Court of Virginia affirmed that decision on January 8, 2026 in a 43-page opinion. The appellate courts identified three specific errors at the trial level:2Justia. Pegasystems Inc. v. Appian Corp.1Justia. Appian Corp. v. Pegasystems Inc.
- The jury instructions improperly shifted the burden of proof on damages to Pegasystems.
- Pegasystems was prevented from authenticating and showing its own software versions to the jury.
- The jury was told that the number of people with access to Appian’s software was not relevant.
The instruction problem was central. The trial court’s charge effectively treated all of Pega’s sales as tainted once misappropriation was shown, which put the burden on Pegasystems to disprove the connection. The appeals court held that a plaintiff must show a direct causal link between the misappropriated secrets and the specific profits it seeks to recover.2Justia. Pegasystems Inc. v. Appian Corp.
The evidentiary ruling also drew reversal. Pegasystems had tried to present versions of its platform to show independent development or prior existence of features. The trial court blocked that evidence because the software was on a different laptop than the one used during early discovery. The higher courts found that exclusion prejudiced the defense.1Justia. Appian Corp. v. Pegasystems Inc.
On the third point, the courts held that the number of users with access to the information is relevant to whether Appian took reasonable efforts to keep it secret, even if that number is not dispositive on its own. Telling jurors to ignore the question was error.1Justia. Appian Corp. v. Pegasystems Inc.
What Happens in the New Trial
The case has been remanded to the Circuit Court of Fairfax County. A new jury will hear the evidence under the corrected standards set out by the appellate courts. Pegasystems will be permitted to present evidence that it developed the challenged software features independently, and the number of people with access to Appian’s information will be a fair subject for the jury to weigh.1Justia. Appian Corp. v. Pegasystems Inc.
Appian will carry a specific burden this time. Under Virginia law, a party seeking recovery for unjust enrichment in a trade secret case must prove that the financial gains were caused by the misappropriation.3Virginia Code Commission. Virginia Code § 59.1-338 – Section: Damages The $2.036 billion figure no longer stands; whether Appian can secure a new judgment, and at what size, will turn on how it meets that causal-link standard the second time around.
