Second Circuit revives SS&C software case and clarifies confidential sharing of trade secrets

The story

A U.S. appeals court has revived SS&C Technologies’ claim that fintech rival Arcesium misappropriated trade secrets from Geneva, SS&C’s portfolio-accounting software, to accelerate competing products. The Second Circuit ruled on November 3 that SS&C’s amended complaint plausibly alleged both protectable trade secrets and improper use. It reversed a Southern District of New York dismissal and returned the case for further proceedings. The decision lets the lawsuit continue; it does not establish that Arcesium copied the software or owes damages.

Geneva was developed by Advent Software and is used by asset managers, hedge funds and other financial firms to consolidate portfolio data. SS&C acquired Advent in 2015. According to the complaint, Geneva includes confidential executable code, an integration layer with application programming interfaces, a data model, loader formats and proprietary portfolio-accounting functions. The Second Circuit counted 14 plausibly identified trade secrets and accepted those allegations as true because the case was at the motion-to-dismiss stage.

The commercial relationship is central. Advent and Arcesium entered a five-year hosted-reseller agreement that allowed Arcesium to sublicense Geneva and support customers. The agreement limited use to those services, required confidentiality and prohibited Arcesium from using Geneva to build competing products. SS&C alleged that Arcesium nevertheless used Geneva information in Trinity, its own portfolio-accounting platform, and in Nautilus, an interface intended to support Geneva users after the reseller agreement expired. Arcesium disputes the allegations.

The district court had agreed that SS&C adequately described trade secrets but found the complaint insufficient on misappropriation. It relied on documents incorporated into the complaint and credited Arcesium’s explanations for internal emails and technical activity. The appellate panel said that crossed the line into fact-finding. At this early stage, courts must draw reasonable inferences for the plaintiff rather than choose the defendant’s interpretation of contested documents.

One part of the opinion has implications beyond this dispute. Arcesium argued that Geneva information could not be secret because SS&C disclosed it to thousands of customers and to Arcesium. The court rejected a rule under which third-party sharing automatically eliminates secrecy. Information can remain protected when it is provided under an understanding of confidentiality. SS&C alleged that access required valid licences and credentials, that customers signed nondisclosure agreements and that the reseller contract imposed specific limits. Those safeguards were enough to plead reasonable protective measures.

That does not mean every software licence creates a trade secret. The federal Defend Trade Secrets Act also requires information to derive independent economic value from not being generally known or readily ascertainable. A claimant must identify the protected material rather than invoke an entire product at a high level. SS&C pointed to executable software, APIs, database structures and methods, while alleging their secrecy had competitive value. Whether each item meets the statutory test will require evidence.

The panel also found the alleged use sufficiently plausible when considered as a whole. SS&C cited internal discussions comparing Arcesium’s technical problems with Geneva’s solutions, efforts to remove Geneva references from Trinity documentation, promises that Trinity would mimic Geneva functionality and an accelerated development timeline. It also alleged Nautilus used Geneva’s integration layer, database schema and data model after contractual access narrowed. These are allegations and circumstantial signals, not proven findings, but the court said they were enough to proceed.

Independent reporting by Law360 described the decision as reviving SS&C’s federal and New York trade-secret claims against Arcesium. The court treated the state claim under substantially the same two-part structure—existence of a trade secret and improper use—and did not separately analyze it. Other state-law claims were outside the appeal. The panel also did not decide whether the district court should have allowed another amended complaint because reversal made that question unnecessary.

INNOVOX analysis: enterprise software rarely stays inside one building. Vendors expose code, data models, interfaces and operating knowledge to customers, cloud hosts, resellers and implementation partners. The decision preserves a route to trade-secret protection through controlled commercialization, but it also shows why generic confidentiality clauses are not the whole answer. Companies need defined access rights, credential records, technical segmentation, post-termination controls and documentation showing which components are secret and why competitors would gain value from them.

What to watch next is the evidence rather than the pleading. Discovery may compare development histories, repositories, specifications, employee communications and the functionality of Geneva, Trinity and Nautilus. Arcesium can still argue that information was public, independently developed, properly licensed or not actually used. SS&C must prove secrecy, reasonable safeguards and misappropriation rather than merely point to similarity. The appellate court’s message is narrower but important: those disputed technical facts belong in an evidentiary process, not a judicial choice between competing explanations at dismissal.

INNOVOX analysis

The decision matters to technology licensing because commercialization often requires controlled disclosure to customers, integrators and support partners. Treating any third-party access as loss of secrecy would make trade-secret protection impractical for enterprise software. The opinion instead turns attention to the quality of access controls, contractual limits and evidence connecting authorized access to an allegedly competing product.

What to watch

Watch discovery over source materials, development records and the technical relationship among Geneva, Trinity and Nautilus. The district court will also have to test whether the alleged information was genuinely secret and economically valuable, whether SS&C’s safeguards were reasonable and whether Arcesium acquired or used anything through improper means.
