A patent infringement lawsuit targeting the United States government over two‑factor authentication technology has been dismissed before trial, the U.S. Court of Federal Claims ruled, after determining that the asserted patent had already been held invalid under the Alice framework in earlier litigation involving the inventors. The decision, handed down in Factor2 Multimedia Systems LLC v. United States, marks a swift end to the 2024 suit and underscores the growing potency of issue preclusion as a defense in software‑patent cases.
Factor2 Multimedia Systems, the exclusive licensee and enforcement vehicle for U.S. Patent No. 8,555,347—a patent describing a system for “multi‑factor authentication of a user and remotely configurable privacy setting for a user device”—filed its complaint in 2024, alleging that various federal agencies, including the Department of Defense and the General Services Administration, had deployed authentication systems that infringed the ‘347 patent. The government moved to dismiss, arguing that because the inventors, Nader and Kamran Asghari, had already lost a challenge to the patent’s validity in a separate district court action, Factor2 was precluded from re‑litigating the question of patent eligibility.
Judge Edward H. Meyers of the Court of Federal Claims agreed, holding that the doctrine of collateral estoppel, or issue preclusion, barred the new lawsuit. The pivotal prior case was Asghari‑Khamirani v. RSA Security LLC, a suit the Asgharis filed in the Eastern District of Texas, alleging that RSA’s authentication products infringed the same patent. The district court granted summary judgment of invalidity, finding that the claims of the ‘347 patent were directed to the abstract idea of “authenticating a user using multiple credential types” and lacked any inventive concept sufficient to transform that idea into a patent‑eligible invention. The Federal Circuit summarily affirmed that ruling without opinion, making it a final judgment on the merits.
“Because the inventors litigated and lost on the very issue of patent‑eligibility,” Judge Meyers wrote, “Factor2, standing in privity with the inventors, is bound by that judgment. Alice preclusion applies.” The court rejected Factor2’s argument that it should be allowed to relitigate because the government’s use of the patented technology was somehow different from RSA’s. The legal question of whether the patent claims eligible subject matter under 35 U.S.C. § 101 is a pure question of law, the judge noted, and once decided adversely to the patent owner, it is dispositive in all subsequent actions involving the same patent.
The ‘347 patent, titled “Secure Multi‑Factor Authentication and User‑Configurable Privacy Control System,” is part of a family of patents the Asghari brothers obtained beginning in the mid‑2000s. It describes a method for authenticating a user by receiving multiple “credential types” through an “input interface” and then combining them with a “privacy setting” that the user can adjust. Like many software patents challenged under Alice, the claims use broad functional language that, according to the Texas court, merely recited a generic computer performing a longstanding business practice—verifying identity—without requiring any specific, non‑conventional technology.
The Supreme Court’s 2014 decision in Alice Corp. v. CLS Bank International established a two‑step test for determining whether a patent claims ineligible subject matter: first, determine whether the claims are directed to a patent‑ineligible concept such as an abstract idea; if so, examine the claim elements individually and as an ordered combination to see if they contain an “inventive concept” that transforms the abstract idea into a patent‑eligible application. Over the past decade, the Federal Circuit has applied this framework to invalidate scores of software and business‑method patents, including numerous authentication and security patents.
Factor2’s loss illustrates how difficult it has become for patent owners to avoid preclusion once an Alice‑based invalidity finding has been made. Unlike factual issues—which can vary between defendants—the question of patent eligibility under § 101 is not tied to a particular accused product. It is determined solely by the patent claims, the specification, and the prior art. Therefore, when one court concludes that a patent fails the Alice test, that holding operates as a blanket ban on all future enforcement efforts, at least against parties who can establish privity.
Privity, the legal relationship that binds a non‑party to a prior judgment, was easily established here. Factor2 was formed by the Asghari brothers specifically to commercialize and enforce the ‘347 patent; it is their alter ego. The court found that Factor2’s interests were so closely aligned with the Asgharis’ that it would be unfair to allow the LLC to escape the consequences of the inventors’ earlier loss. This is a textbook application of the Supreme Court’s 2008 decision in Taylor v. Sturgell, which set the modern boundaries for non‑party preclusion.
The Federal Claims court’s ruling also highlights a strategic vulnerability for patent holders who sue the government. The United States, as a frequent user of off‑the‑shelf commercial software and hardware, is often a target for patent infringement suits. But the government has robust defenses unavailable to many private defendants. In addition to sovereign immunity and the ability to seek administrative review via the Patent Trial and Appeal Board, the government can now invoke Alice preclusion with increasing confidence, knowing that the Federal Circuit’s settled § 101 jurisprudence has made it rare for a software patent to survive a well‑argued Alice motion.
For the broader technology industry, the Factor2 decision is unlikely to cause immediate shockwaves. Two‑factor authentication has been widely deployed for years, and the underlying techniques are now ubiquitous in everything from email login to enterprise VPN access. The patent community, however, will note the efficiency with which the government dispatched the suit. By filing a motion to dismiss under Rule 12(b)(6) of the Rules of the Court of Federal Claims—rather than enduring years of expensive discovery—the Department of Justice eliminated a lawsuit that, in a pre‑Alice era, might have lingered for half a decade or more.
Factor2 has the right to appeal the dismissal to the U.S. Court of Appeals for the Federal Circuit. Legal observers, however, consider a successful appeal unlikely. The Federal Circuit has been singularly unreceptive to attempts to re‑litigate § 101 eligibility after a final judgment, particularly when the earlier decision was upheld on appeal. Moreover, the Supreme Court has repeatedly denied certiorari in cases seeking to clarify or overturn the Alice framework, leaving it as the law of the land for the foreseeable future.
The Asghari brothers are serial inventors and patent holders in the authentication space. Court records show that they have filed multiple lawsuits over related patents, with mixed results. The RSA case was their first major loss, and the preclusion ruling in Factor2 all but ensures that the ‘347 patent can never be asserted again—against the government or anyone else. For Nader and Kamran Asghari, the dream of monetizing their two‑factor authentication invention through litigation appears to have reached its end.
This outcome is consistent with the broader trend of courts applying Alice to clear out what many judges consider low‑quality software patents. Since 2014, the Federal Circuit has affirmed findings of ineligibility in well over 90% of appeals from district court § 101 decisions. The patent bar has long complained that the Alice framework is unpredictable and threatens legitimate software innovation, but legislative efforts to reform § 101 have stalled in Congress, leaving the courts to continue as the primary gatekeepers.
For technology companies and government contractors that develop or deploy authentication systems, the Factor2 decision is a welcome reinforcement of the status quo. It signals that even when a patent owner finds a deep‑pocketed defendant like the federal government, a prior Alice loss will likely shut the case down before any serious litigation costs are incurred. In‑house counsel will undoubtedly add the case to their collection of precedents to cite in cease‑and‑desist responses.
The case is Factor2 Multimedia Systems LLC v. United States, No. 24-_ (Fed. Cl. decided _). The exact date of the order and the docket number were not immediately available in the public record, though the dismissal was entered in 2025. Factor2 is represented by the law firm Devlin Law Firm LLC; the United States by the Department of Justice’s Civil Division, Commercial Litigation Branch, Intellectual Property Section.
For Windows and enterprise IT professionals, the decision is a reminder that while two‑factor authentication remains a critical layer of security defense, the intellectual property landscape around it is littered with failed patent assertions. The Alice precedent continues to curtail the monopolization of abstract authentication concepts, ensuring that widely adopted security practices remain free from royalty burdens. As the U.S. government itself moves toward a zero‑trust architecture and mandates multi‑factor authentication for all federal systems, the clearance of patent thickets like the ‘347 patent removes potential procurement delays and cost spikes.
In the end, Factor2 v. United States will be remembered not as a landmark in Alice jurisprudence but as a textbook application of preclusion doctrine to patent eligibility. It stands as a cautionary tale for patent owners who, after an initial loss, consider repackaging their patents through new assignee entities. The courts have watched this tactic before and are ready to apply collateral estoppel to maintain finality. For Nader and Kamran Asghari, the dismissal likely writes the final chapter of a decade‑long effort to extract value from their two‑factor authentication portfolio.
