BrowserKey v. First Citizens Bank: Patent Infringement Dismissed With Prejudice
BrowserKey, LLC asserted US7249262B2 — a web and mobile authentication patent — against First Citizens Bank & Trust Co. in the Eastern District of Texas. The parties filed a joint motion to dismiss after 182 days, with plaintiff’s claims dismissed with prejudice and defendant’s counterclaims dismissed without prejudice. Each party bears its own costs.
Authentication patent dispute resolved via joint dismissal in E.D. Texas
BrowserKey, LLC, an entity holding US7249262B2, filed suit against First Citizens Bank & Trust Co. on April 30, 2025 in the Eastern District of Texas, Case No. 2:25-cv-00451. The complaint alleged infringement of a patent directed to web and mobile application authentication technology, specifically targeting First Citizens’ consumer-facing web and mobile banking applications. Fabricant LLP and Truelove Law Firm represented the plaintiff; McGuireWoods LLP defended the bank.
The case closed on October 29, 2025 — just 182 days after filing — when the Court granted a Joint Motion to Dismiss. Plaintiff’s claims were dismissed with prejudice, permanently barring BrowserKey from re-asserting the same patent claims against First Citizens. Defendant’s counterclaims, however, were dismissed without prejudice, leaving First Citizens the theoretical option to revive those claims in a future proceeding, though this is uncommon following a negotiated resolution.
Resolution in under six months is notably swift for patent litigation in the Eastern District of Texas, suggesting the parties reached a private agreement — likely a license or covenant not to sue — shortly after the action was filed. The public record does not disclose any financial terms. The asymmetric dismissal structure (plaintiff with prejudice, defendant without) is a standard transactional outcome in resolved patent disputes and does not necessarily indicate either party conceded infringement or invalidity on the merits.

Joint dismissal with prejudice: what the asymmetric outcome means for both parties
Joint motion to dismiss terminates the action on agreed terms
A joint motion to dismiss reflects a bilateral agreement to end litigation. The Court grants dismissal without ruling on the merits. Here, plaintiff’s claims were dismissed with prejudice — a permanent bar under res judicata — while defendant’s counterclaims were dismissed without prejudice. This asymmetric structure is typical when a patent holder has granted a license or covenant not to sue, and the accused infringer retains theoretical future optionality on its invalidity or non-infringement counterclaims.
Consensual resolutionWith-prejudice dismissal bars BrowserKey from re-filing against First Citizens
Dismissal with prejudice on plaintiff’s claims operates as a final judgment on the merits. BrowserKey cannot refile this infringement action against First Citizens based on US7249262B2 for the same accused products. This outcome is consistent with a negotiated license or lump-sum settlement: the patent holder receives consideration and, in exchange, permanently relinquishes its infringement claims against this defendant. The public record does not disclose any financial terms.
Claims permanently barredFirst Citizens’ counterclaims survive — dismissed without prejudice
First Citizens’ counterclaims — likely seeking invalidity or non-infringement declarations — were dismissed without prejudice. This means those claims are not extinguished and could theoretically be re-filed, though in practice they are rarely revived after a patent dispute resolves. This structure is standard negotiating currency: the bank retains a defensive option while the patent holder secures a clean exit. No costs or fees were awarded to either party.
Counterclaims preservedSwift resolution signals a licensing-driven enforcement strategy
A 182-day case lifecycle in E.D. Texas — before any Markman hearing or substantive motion practice — is consistent with a pre-dispute licensing demand resolved through litigation. Financial institutions deploying web and mobile authentication technology remain targets for assertion of older internet-era patents like US7249262B2. This outcome does not resolve the patent’s validity or claim scope, meaning other banks or fintechs in BrowserKey’s crosshairs face the same calculus: litigate or license.

Official order — verbatim text
The Court’s order grants a joint motion to dismiss, reflecting a fully negotiated resolution with no merits adjudication. The structural asymmetry — plaintiff’s claims dismissed with prejudice, defendant’s counterclaims without prejudice — is commercially significant: BrowserKey permanently surrenders its right to re-assert US7249262B2 against First Citizens, while the bank preserves its invalidity and non-infringement positions in form. Each party bearing its own costs suggests neither party extracted a fee-shifting concession, consistent with a balanced private settlement.
US7249262B2 — web and mobile application authentication technology
US7249262B2 (application no. US10/139924) is a granted U.S. utility patent directed to authentication technology for web and mobile applications. Filed in the early 2000s internet era, the patent covers methods and systems for managing user credentials and sessions in browser and mobile environments — a foundational concern for any institution operating consumer-facing digital products. The patent’s claims are likely directed to the mechanisms by which a browser or mobile client authenticates a user and maintains a secure session.
For the financial services sector, this patent’s strategic significance lies in its breadth: virtually every bank, credit union, and fintech operating a web portal or mobile app relies on authentication workflows that could fall within the scope of similarly framed claims. The assertion against First Citizens’ web and mobile banking applications signals that BrowserKey is targeting mainstream financial institutions with large digital user bases. With the patent still enforceable and no invalidity ruling on the record, competitors in the digital banking space remain exposed to parallel assertions.
Should you run an FTO analysis against US7249262B2?
Any financial institution, fintech, or technology vendor that deploys web or mobile application authentication — including login flows, session tokens, SSO integrations, or browser-based credential management — should assess freedom to operate against US7249262B2. The patent’s assertion against a major bank’s consumer digital products indicates active enforcement. This is not a dormant patent: it has been litigated in 2025, and the absence of an invalidity ruling means claim scope has not been judicially narrowed.

What this case signals for the fintech and banking IP landscape
Authentication patent assertions against financial institutions are accelerating. This case illustrates the economics and risk calculus defendants face.
E.D. Texas remains the preferred venue for authentication patent assertions
BrowserKey filed in the Eastern District of Texas — a plaintiff-friendly forum with established patent litigation infrastructure. Financial institutions should anticipate that web and mobile authentication patents will continue to be asserted there, and should prepare venue transfer arguments and local counsel relationships proactively.
With-prejudice dismissal protects the defendant but does not resolve claim scope
First Citizens secured a permanent bar against BrowserKey re-filing on these specific claims. However, US7249262B2 remains enforceable against other parties. Banks and fintechs using comparable authentication architectures should assess their own exposure independently — this case’s resolution offers no safe harbour to third parties.
BrowserKey v First — key questions answered
The case was dismissed via joint motion. BrowserKey’s infringement claims against First Citizens Bank were dismissed with prejudice — permanently barring re-filing — while First Citizens’ counterclaims were dismissed without prejudice. Each party bore its own costs. No merits ruling was issued.
US7249262B2 covers web and mobile application authentication technology, including methods for managing user credentials and sessions in browser and mobile environments. It was asserted against First Citizens Bank’s consumer-facing web and mobile banking applications — products that rely on exactly these kinds of authentication workflows.
Dismissal with prejudice operates as a final judgment on the merits under res judicata. BrowserKey is permanently barred from re-asserting the same patent claims against First Citizens Bank for the same accused products. However, the patent remains enforceable against other parties who have not obtained a similar dismissal or license.
The asymmetric dismissal structure — plaintiff’s claims with prejudice, defendant’s counterclaims without prejudice — is a standard negotiated outcome. It typically reflects the defendant retaining theoretical invalidity or non-infringement claims as a bargaining chip, while the patent holder obtains a clean, permanent release of infringement liability. In practice, without-prejudice counterclaim dismissals are rarely revived post-settlement.
No. The joint dismissal was granted without any merits adjudication. The Court did not rule on infringement, invalidity, or claim scope. US7249262B2 remains a granted, enforceable U.S. patent. Third parties — including other financial institutions and fintechs — cannot rely on this case’s outcome as any indication of the patent’s validity or enforceability against them.
