Texas Secure Authentication v. Fifth Third Bank: Settled in 168 Days
Texas Secure Authentication, LLC asserted US7873682B2 — covering dynamic-register information container systems — against Fifth Third Bank in Ohio’s Northern District. The parties reached a settlement in principle within 168 days of filing, with a final dismissal order anticipated by December 2024.
A swift in-principle settlement over secure authentication IP
On May 28, 2024, Texas Secure Authentication, LLC filed a patent infringement action against Fifth Third Bank in the U.S. District Court for the Northern District of Ohio (Case No. 4:24-cv-00931), assigned to Judge Benita Y. Pearson. The single patent asserted — US7873682B2, filed under application number US12/691425 — covers a system and method for creating and manipulating information containers with dynamic registers, a technology with evident relevance to secure digital authentication and banking workflows.
The case closed on November 12, 2024, just 168 days after filing, when the parties filed a Joint Motion to Stay alongside a Notice of Settlement. The court marked the docket ‘settled and dismissed without prejudice,’ giving the parties until December 2, 2024 to file an executed Stipulation and Order of Dismissal with Prejudice — or alternatively, for the plaintiff to move to reopen. The without-prejudice posture at the time of closure is therefore provisional, pending that final stipulation.
A resolution within six months of filing suggests either early commercial alignment between the parties or pre-litigation licensing discussions that carried into the case. The public record does not disclose financial terms, licensing royalties, or product-level admissions. Whether the anticipated dismissal with prejudice was ultimately filed by the December 2024 deadline remains unconfirmed from the available docket data, leaving the full finality of the resolution technically open to interpretation.
Filing to Case Settled in 168 days

Case settled: what the dismissal structure means for both parties
Settled and dismissed without prejudice — provisionally
The court’s order marks the docket ‘settled and dismissed without prejudice’ as an interim measure following a Notice of Settlement. This is a holding posture: the parties had 30 days to memorialise terms and file a Stipulation of Dismissal With Prejudice. If that stipulation was filed, the with-prejudice dismissal would supersede this order and fully close the case. The public record at case closure does not confirm that final step was completed.
Conditional dismissal structureWith or without prejudice — the stakes for Texas Secure Authentication
A dismissal without prejudice preserves the plaintiff’s right to refile the same infringement claims against Fifth Third Bank. A dismissal with prejudice permanently bars refiling on the same claims. The court’s order explicitly contemplated a transition to with-prejudice dismissal upon filing of the stipulation. The public record at the time of docket closure is silent on whether that transition was completed, so it is not possible to confirm definitively which finality standard applies.
Refiling rights uncertainFifth Third Bank avoids merits adjudication
Fifth Third Bank retained counsel from both Goodwin Procter (Boston) and Dinsmore & Shohl (Cincinnati) — a dual-firm defence typically consistent with anticipated complexity. Settling before claim construction or any merits ruling means no court has adjudicated infringement or validity of US7873682B2 in this proceeding. The bank avoids an adverse judgment and limits public exposure of its authentication systems, though settlement terms may impose licensing or operational obligations not visible in the public record.
No merits ruling on infringementRapid settlement suggests licensing leverage for the patent holder
A 168-day resolution in a patent case against a large regional bank is notably fast and suggests Texas Secure Authentication’s assertion carried sufficient licensing leverage to prompt early engagement. For other financial institutions using dynamic-register authentication architectures, this settlement — combined with the intact, unchallenged patent — signals that US7873682B2 remains a live enforcement risk. No IPR or validity challenge appears in the public record, leaving the patent’s claims fully presumptively valid.

Official order — verbatim text
The court’s order reflects a staged dismissal architecture common in patent settlements: an immediate without-prejudice marker to close the active docket, paired with a deadline for the parties to file a stipulated with-prejudice dismissal. The phrase ‘settled in principle’ confirms no final written agreement existed at the time of the order. No merits adjudication — on infringement, validity, or damages — was issued. The patent’s claims therefore remain legally intact and the case provides no binding precedent on the scope of US7873682B2.
US7873682B2 — Dynamic-register information container system
US7873682B2, filed under application number US12/691425, covers a system and method for creating and manipulating information containers with dynamic registers. The patent sits at the intersection of secure data management and authentication architecture — technology domains central to online and mobile banking infrastructure. Dynamic registers in this context suggest mutable, state-aware data structures used to control access and manage secure sessions, a design pattern widely deployed across financial services platforms.
For financial institutions, the strategic significance of this patent lies in its potential breadth across common authentication workflows. If the claims read on session-token management, secure container-based credential storage, or dynamic access-rights assignment, a large portion of the banking sector’s digital infrastructure could fall within the assertion perimeter. The fact that Fifth Third Bank settled without filing an IPR or receiving a claim construction ruling means no public record narrows or limits the patent’s enforceable scope — a situation that typically emboldens continued assertion against other institutions.
Should you run an FTO analysis against US7873682B2?
Any bank, credit union, or fintech company operating dynamic authentication systems, secure session containers, or token-based access management should consider a freedom-to-operate review against US7873682B2. The patent survived this litigation intact, with no claim construction order, no IPR, and a confidential settlement — meaning its enforceable scope is undefined from the public record. Product teams building or procuring digital banking authentication workflows face direct exposure.
PatSnap Eureka’s FTO Search Agent can map US7873682B2’s claim language against your specific product architecture, identify prior art that could support an IPR petition, and surface related family members that may extend the assertion risk. For in-house IP teams at financial institutions, running this analysis proactively — before receiving a demand letter — is significantly more cost-effective than responding to litigation.

What this case signals for the financial authentication IP landscape
A quick settlement against a major bank, with no validity challenge filed, reinforces Texas Secure Authentication’s enforcement posture across the sector.
No IPR filed: US7873682B2 remains fully presumptively valid
Neither party filed an inter partes review petition during the 168-day case window. That leaves US7873682B2 unchallenged at the USPTO. Banks and fintech firms operating similar dynamic-register or information-container authentication systems should treat this patent as an active enforcement risk with no known prior-art-based invalidity record.
Dual big-law defence did not prevent early settlement
Fifth Third Bank fielded attorneys from both Goodwin Procter and Dinsmore & Shohl, suggesting initial expectations of a protracted fight. The rapid settlement despite that investment typically signals that claim scope analysis or commercial calculus — rather than a weak case — drove the resolution. Other defendants facing similar assertions should not assume a dual-firm strategy will delay resolution.
Texas v Fifth — key questions answered
Texas Secure Authentication asserted US7873682B2, filed under application number US12/691425. The patent covers a system and method for creating and manipulating information containers with dynamic registers — a technology relevant to secure authentication and session management in banking systems.
The case settled in principle after 168 days. On November 12, 2024, the court marked the docket ‘settled and dismissed without prejudice’ following a Joint Motion to Stay and Notice of Settlement. The parties were given until December 2, 2024 to file a Stipulation of Dismissal with Prejudice. Settlement terms were not publicly disclosed.
No inter partes review petition is recorded in connection with this case. The patent was not subjected to a validity challenge at the USPTO during the 168-day litigation window, leaving US7873682B2 presumptively valid with its full claim scope legally intact.
A without-prejudice dismissal preserves the plaintiff’s right to refile the same claims against Fifth Third Bank. However, the court’s order contemplated a superseding dismissal with prejudice upon the parties filing a stipulation by December 2, 2024. Whether that final step was completed is not confirmed in the available public record, leaving the ultimate refiling posture uncertain.
Texas Secure Authentication was represented by Banie & Ishimoto (Palo Alto) and Sand, Sebolt & Wernow Co., LPA, with attorneys Howard L. Wernow and John A. Lee. Fifth Third Bank fielded a dual-firm defence: Goodwin Procter LLP (Boston) and Dinsmore & Shohl LLP (Cincinnati), with attorneys Douglas J. Kline, Oleg Khariton, and Robert Frederickson III.
