AuthWallet v. Cullen/Frost Bankers: Mobile Payment Patent Dismissed With Prejudice
AuthWallet, LLC asserted US8099368B2 — a patent covering intermediary mobile device confirmation of financial transactions — against Texas regional bank Cullen/Frost Bankers. The case ended after 378 days when both parties jointly stipulated to dismissal with prejudice, permanently closing AuthWallet’s claims.
Mobile authentication patent hits a Texas bank — then vanishes quietly
On March 1, 2024, AuthWallet, LLC filed suit against Cullen/Frost Bankers, Inc. in the U.S. District Court for the Western District of Texas (Case No. 7:24-cv-00066), asserting infringement of US8099368B2. The patent claims an intermediary service and method for processing financial transaction data using mobile device confirmation — a technology squarely relevant to modern mobile banking and payment authentication workflows.
The litigation concluded on March 13, 2025, when the parties filed a Joint Stipulation of Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court granted the dismissal the following day. Under Rule 41, such a stipulation becomes effective automatically upon filing and requires no judicial approval. Critically, the ‘with prejudice’ designation means AuthWallet permanently forfeits the right to reassert these specific patent claims against Cullen/Frost Bankers in any future action.
The 378-day duration — spanning filing through pre-trial phases — is consistent with resolution before costly claim construction or merits briefing, which typically suggests the parties reached a negotiated resolution. Whether that involved a licensing agreement, covenant not to sue, or pure walk-away is not disclosed in the public record. Ramey LLP, counsel for AuthWallet, has a well-documented history of asserting financial technology patents, which lends context to the speed and terms of this resolution.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): automatic dismissal by joint stipulation
A stipulated dismissal under Rule 41(a)(1)(A)(ii) takes effect the moment it is filed — no court order is needed. The Fifth Circuit confirmed in Yesh Music v. Lakewood Church that such dismissals are ‘effective automatically upon filing.’ Here, both parties signed, making the March 13, 2025 filing the operative termination date regardless of the court’s subsequent order.
Procedural — no merits rulingWith prejudice: AuthWallet’s claims are permanently extinguished
Dismissal ‘with prejudice’ functions as a final adjudication on the merits for res judicata purposes. AuthWallet cannot re-file suit against Cullen/Frost Bankers on US8099368B2 for the same accused conduct. This is the most decisive form of voluntary dismissal available — distinguishable from a ‘without prejudice’ dismissal, which would preserve the right to re-file. The public record does not disclose what consideration, if any, Cullen/Frost provided in exchange.
Claims permanently barredAuthWallet gives up its claims — but terms remain undisclosed
AuthWallet’s decision to stipulate to dismissal with prejudice suggests either a negotiated resolution satisfactory to both sides, or a strategic retreat. The patent US8099368B2 remains valid and potentially enforceable against third parties — only the claims against Cullen/Frost are extinguished. AuthWallet retains the right to assert this patent against other defendants.
Patent survives; this claim does notCullen/Frost exits with full immunity on these claims
Cullen/Frost Bankers, represented by Polsinelli PC, secures a with-prejudice dismissal — the strongest possible exit short of a merits verdict. The bank faces no ongoing liability on US8099368B2 for the accused mobile transaction processing conduct. Whether this reflects a payment, license, or successful pre-litigation posturing is not public. Any future mobile payment product expansion is insulated from this specific patent threat from AuthWallet.

Official order — verbatim text
The joint stipulation recites that ‘Plaintiff’s claims against Defendant should be dismissed with prejudice’ — language that is deliberately mutual and consent-based, not concessive. The court’s invocation of Rule 41(a)(1)(A)(ii) and the Fifth Circuit’s Yesh Music standard confirms this is a procedural termination with no merits adjudication. Neither patent validity nor infringement was determined. The with-prejudice designation, however, carries substantive weight: it creates a res judicata bar specific to Cullen/Frost, while leaving AuthWallet’s enforcement rights fully intact against the broader market.
US8099368B2 — Mobile Device Confirmation for Financial Transaction Processing
US8099368B2, filed under application number US12/557457, claims an intermediary service and method for processing financial transaction data with mobile device confirmation. The patent sits at the intersection of payment processing infrastructure and mobile authentication — covering the workflow by which a transaction is routed through an intermediary that solicits real-time confirmation from a user’s mobile device before settlement. This architecture is foundational to fraud-reduction mechanisms in modern digital banking.
The commercial significance of this patent is substantial: mobile-confirmed transaction processing is no longer a premium feature but a baseline expectation in consumer banking apps, contactless payment systems, and two-factor payment authorisation flows. Any financial institution, payment network, or fintech offering push-notification or SMS-based transaction approval could fall within the claims’ scope. The patent’s continued validity — unchallenged through this litigation — leaves it as an active assertion risk across the sector.
Should you run an FTO analysis against US8099368B2?
If your organisation operates or is developing a mobile banking app, payment gateway, or any service that routes financial transactions through an intermediary layer with mobile device confirmation — including push-notification approvals, SMS OTPs, or biometric-gated payment flows — US8099368B2 is a patent your IP team should formally assess. The Cullen/Frost case demonstrates that AuthWallet is prepared to litigate in W.D. Texas, and the with-prejudice dismissal only shields that one defendant.
PatSnap Eureka’s FTO Search Agent enables R&D and legal teams to map US8099368B2’s claim language against your specific product architecture, identify prior art that may support invalidity arguments, and benchmark your exposure against the full landscape of mobile payment authentication patents. Early FTO work is substantially cheaper than reactive litigation defence — particularly in a venue as active as the Western District of Texas.

What this case signals for the fintech and mobile banking IP landscape
Mobile payment authentication patents remain an active litigation vector against financial institutions. This case illustrates how banks are navigating the risk.
Mobile authentication patents are a live threat to regional banks
US8099368B2 targets intermediary mobile confirmation of financial transactions — functionality embedded in virtually every modern banking app. Regional banks without deep patent litigation infrastructure, like Cullen/Frost, are natural targets. IP teams at financial institutions should audit their mobile authentication stack against issued patents in this space.
Ramey LLP’s litigation pattern warrants monitoring by fintech IP teams
Plaintiff’s counsel William P. Ramey III and Ramey LLP are prolific asserters of financial technology patents in Texas federal courts. A with-prejudice dismissal within 378 days — before claim construction — is consistent with their portfolio monetisation strategy. In-house teams should track this firm’s docket for early warning of related assertions.
AuthWallet v Cullen/Frost — key questions answered
Dismissal with prejudice means AuthWallet’s patent infringement claims against Cullen/Frost Bankers are permanently extinguished. AuthWallet cannot re-file the same claims based on US8099368B2 against Cullen/Frost for the same accused conduct. The dismissal was entered by joint stipulation under Rule 41(a)(1)(A)(ii) and carries res judicata effect specific to this defendant.
No. The case was terminated by joint stipulation of dismissal before any merits ruling. Patent validity and infringement were never adjudicated. US8099368B2 remains a granted, presumptively valid patent that AuthWallet retains the right to enforce against third parties not covered by this dismissal.
The public record does not disclose any financial terms. The parties filed a joint stipulation of dismissal with prejudice on March 13, 2025, but no settlement agreement, licensing deal, or payment has been made public. The with-prejudice designation suggests a negotiated resolution, but the specific consideration — if any — is unknown.
US8099368B2 covers an intermediary service and method for processing financial transaction data with mobile device confirmation — broadly, systems where a transaction is routed through an intermediary that seeks real-time mobile device approval before completing payment. Financial institutions, payment processors, and fintechs operating push-notification payment approvals or SMS-based transaction confirmation workflows may face exposure.
W.D. Texas, and particularly the Waco Division, has been a preferred venue for NPE patent assertions due to historically fast docket speeds and plaintiff-friendly procedural history. Ramey LLP, AuthWallet’s counsel, regularly files patent cases in this district. While 2022 standing order changes reduced some of its NPE appeal, W.D. Texas remains an active patent litigation venue.
