Appian Corporation v. Pegasystems Inc. is a Virginia case between two competing vendors of business process management (BPM) and “low-code” platforms. It is not an audit or overuse case, but the facts turn on who may use licensed software and trial accounts and under what terms. Appian alleged that Pegasystems (“Pega”) had, from 2012, used a contractor who had access to Appian’s platform and partner documentation through his employer’s licence to study Appian’s software and share its documentation. A jury awarded Appian US$2,036,860,045 against Pega.[1] The Court of Appeals of Virginia reversed the judgment on damages and evidentiary grounds in July 2024 and remanded for a new trial on the trade secret claims. On 8 January 2026 the Supreme Court of Virginia affirmed that judgment and remanded for further proceedings.[2][1]
Background
The Supreme Court described Appian and Pega as “aggressively direct competitors” selling BPM platforms.[1] In 2012, Pega’s head of competitive intelligence hired a staffing firm to find an experienced Appian developer with access to Appian’s systems. The developer, Youyong Zou, worked for a government contractor, Serco, that licensed Appian’s platform, and as an employee of an Appian business partner he also had access to Appian Forum, a password-protected website with documentation and software downloads.[1]
Pega employees testified that Appian “would not have sold [Pega] a license”. Zou made video tutorials of himself building applications in Appian, took part in presentations to Pega, and downloaded and shared Appian documentation.[1] After Zou lost access to Appian’s server in 2014, Pega employees used aliases and non-Pega credentials to try to open Appian free trials.[1]
The licence and access terms in issue
The court quoted the Appian Forum terms. Documents could be downloaded, viewed, copied and printed only for “personal, informational, and non-commercial purposes” and could not otherwise be used, copied, published or distributed without Appian’s written consent. Software accessed through the site was subject to a separate software licence agreement, and anyone without such an agreement was prohibited from downloading, accessing or using it without consent.[1] Pega showed that Appian licensees, often resellers, could install software to demonstrate it to prospective customers without confidentiality agreements, under supervision, and that free trials were available under click-through (“clickwrap”) terms.[1] It also proffered evidence of about 45,000 Appian Forum registrations between 2012 and 2021 and more than 13,000 free trial registrations.[1]
Decision or outcome
The claims that went to the jury were under the Virginia Uniform Trade Secrets Act and the Virginia Computer Crimes Act. The trial lasted seven weeks, and the jury awarded US$2,036,860,045 against Pega and US$5,000 against Zou for the trade secret violation.[1] The Court of Appeals called it the largest damages verdict in the history of Virginia.[2]
The Supreme Court of Virginia held that the evidence was sufficient for the jury to find misappropriation, in part because Pega had needed elaborate and improper methods to reach the information and because trial users were bound by click-through terms limiting use. It agreed with the Court of Appeals that the circuit court erred by instructing the jury that Pega bore a burden of proof on damages and that the number of people with access to a purported trade secret was irrelevant. It also agreed that the circuit court had abused its discretion in enforcing its reading of a Pega interrogatory response and in barring Pega from authenticating and possibly introducing relevant versions of its software. It affirmed the Court of Appeals and remanded.[1] The sources reviewed do not record any retrial or settlement.
Significance for software licensing and SAM practice
- Terms of access are evidence. The court relied on the Appian Forum terms, the partner licence structure and the click-through trial terms when assessing whether Appian had taken reasonable steps to protect its information.[1]
- Partner and contractor access is a licence-scope question. The access at the centre of the case came through an employer’s licence and a partner account used for a competitor’s purposes.[1]
- Evaluation and trial access. The numbers of trial and forum registrations were argued as evidence of weak secrecy, and the appellate courts held the exclusion of that evidence to be an error.[2][1]
Lessons learned
- Keep competitor and onward-sharing restrictions in portal and trial terms. The quoted Forum terms were central to the secrecy analysis.[1]
- Treat a licensee’s partner or contractor accounts as a controlled channel. The access that mattered in this case was obtained through them.[1]
- Do not assume that a very large verdict will stand. Both appellate courts found errors in the damages instruction and in evidentiary rulings.[2][1]
