Dynapass IP Holdings v. Wells Fargo — Authentication Patent Dismissed With Prejudice
Dynapass IP Holdings LLC asserted US6993658B1, a personal communication device authentication patent, against Wells Fargo & Co. and Wells Fargo Bank, N.A. in the Eastern District of Texas. The parties jointly moved to dismiss with prejudice after 580 days, closing the member case while broader consolidated proceedings remained live.
Authentication patent action against Wells Fargo ends with finality
On June 17, 2022, Dynapass IP Holdings LLC filed suit against Wells Fargo & Co. and Wells Fargo Bank, N.A. in the U.S. District Court for the Eastern District of Texas, asserting infringement of US6993658B1 — a patent covering the use of personal communication devices for user authentication. The case was docketed as member case No. 2:22-cv-00217 within a broader series of consolidated proceedings before Judge Gilstrap’s court, suggesting Dynapass was pursuing coordinated licensing litigation across multiple defendants simultaneously.
The case concluded on January 18, 2024, when the court granted a Joint Motion to Dismiss filed by both parties. The dismissal was entered with prejudice, meaning Dynapass permanently relinquished its right to reassert the same claims against Wells Fargo entities arising from this action. The court also ordered each party to bear its own costs, expenses, and attorneys’ fees — a structure that typically signals a negotiated resolution rather than a unilateral concession, though the financial terms of any underlying agreement remain confidential.
The 580-day duration and the joint nature of the motion are consistent with a settlement reached after substantive pre-trial activity, including what the docket reference to Dkt. No. 184 suggests was an advanced stage of litigation. What remains unknown is whether any licensing arrangement accompanied the dismissal — a common feature in NPE-driven portfolio assertions. Notably, the Lead Case No. 2:22-cv-212 remained open at the time of this dismissal, indicating Dynapass’s authentication patent campaign against other defendants was ongoing.

Dismissed with prejudice — Dynapass permanently barred from refiling against Wells Fargo
Joint motion signals mutual agreement, not capitulation
A Joint Motion to Dismiss is filed by both parties together, distinguishing it from a unilateral voluntary dismissal. Here, Dynapass and Wells Fargo jointly represented that the member case had been ‘resolved’ — language that strongly suggests a confidential settlement agreement underpinned the motion, though no financial terms are disclosed in the public record.
Joint resolution inferredWith prejudice: Dynapass cannot refile this specific action
Dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. Dynapass IP Holdings cannot reassert the same claims under US6993658B1 against Wells Fargo & Co. or Wells Fargo Bank, N.A. arising from this action. This provides Wells Fargo with durable finality — a meaningful protection compared to a without-prejudice dismissal, which would leave the threat of refiling intact.
Permanent bar on refilingEach party bears own costs — neutral cost order
The court ordered each party to bear its own costs, expenses, and attorneys’ fees. This is a neutral outcome consistent with a negotiated resolution. Had Wells Fargo prevailed on a dispositive motion, it may have sought fee-shifting under 35 U.S.C. § 285 for an exceptional case. The absence of a fee award to either side is consistent with a settlement that rendered further litigation moot before such determinations were made.
No fee-shifting awardedMember case closed; Lead Case 2:22-cv-212 remained open
This case was one member case within a consolidated series in E.D. Texas. The court directed the clerk to close No. 2:22-cv-217 while maintaining Lead Case No. 2:22-cv-212 as open. This structure is typical of NPE portfolio litigation where a patent holder sues multiple defendants in coordinated actions, resolving individual member cases as settlements are reached with each defendant, while the broader campaign continues.

Stipulation of dismissal — official text
The court’s order grants the parties’ Joint Motion to Dismiss and dismisses all claims with prejudice — meaning the dismissal carries the legal weight of a final judgment on the merits for res judicata purposes. The phrase ‘the above-captioned member case has been resolved’ in the motion, as recited in the order, is deliberately neutral and does not confirm or deny a financial settlement. The instruction to maintain the Lead Case as open confirms this was a defendant-specific resolution within a broader, ongoing multi-party enforcement campaign by Dynapass.
US6993658B1 — Personal Communication Device User Authentication
US6993658B1 (application number US09/519829) claims systems and methods for authenticating users via personal communication devices — technology that anticipated the wave of mobile-based identity verification now standard in banking, fintech, and enterprise security. The patent’s application predates the mass-market smartphone era, which may position it as foundational prior art relative to many modern implementations. Its claims likely cover core interactions between a communication device and an authentication server, making it broadly applicable across consumer-facing digital services.
For financial institutions, US6993658B1 represents the kind of early-priority authentication patent that NPE holders deploy against large, high-revenue targets where the cost of litigation risk may approach or exceed a licensing fee. Dynapass’s willingness to file consolidated cases in E.D. Texas against multiple defendants simultaneously — including a major bank — signals confidence in the patent’s claim scope. Any company deploying SMS-based, app-based, or device-certificate authentication in customer-facing products should treat this patent as a live enforcement risk until the Lead Case is fully resolved.
Should your team run an FTO against US6993658B1?
If your organization operates mobile banking apps, two-factor authentication systems, digital identity verification, or any service where a personal communication device is used to authenticate a user, US6993658B1 is directly relevant to your freedom-to-operate posture. The Dynapass v. Wells Fargo action confirms this patent is being actively asserted against large financial services firms — and with the Lead Case still open, enforcement activity has not concluded.
PatSnap Eureka’s FTO Search Agent can map the specific claims of US6993658B1 against your product architecture, identify design-around options, and surface prior art that could support an invalidity argument if you are approached for a license.

What this case signals for the authentication IP enforcement landscape
Dynapass’s coordinated E.D. Texas campaign targeting financial services firms over authentication technology warrants close monitoring by any institution deploying similar systems.
E.D. Texas remains the preferred venue for NPE authentication patent campaigns
Dynapass filed multiple consolidated cases in the Eastern District of Texas — a jurisdiction well-known for patent-plaintiff-friendly procedural timelines and local rules. Financial institutions with authentication systems should assess exposure to US6993658B1 and related portfolio assets, particularly given the active Lead Case suggests other defendants remain in the fight.
With-prejudice dismissal protects Wells Fargo; others in the suit face ongoing risk
Wells Fargo’s with-prejudice exit closes the door on Dynapass re-asserting these specific claims. But with Lead Case 2:22-cv-212 still open at the time of closure, other financial institutions named as co-defendants in the consolidated series remain exposed. Banks and fintechs using personal device authentication should review their design-arounds and prior art positions against US6993658B1.
Dynapass v Wells — key questions answered
The case was dismissed with prejudice on January 18, 2024, pursuant to a Joint Motion to Dismiss filed by both parties. The court ordered each party to bear its own costs and attorneys’ fees. The dismissal permanently bars Dynapass from refiling the same claims against Wells Fargo entities in this action.
Dynapass asserted US6993658B1 (application no. US09/519829), a patent covering the use of personal communication devices for user authentication. This patent’s claims are relevant to mobile banking, two-factor authentication, and digital identity verification systems widely deployed in financial services.
Dismissal with prejudice operates as a final judgment on the merits. Dynapass IP Holdings LLC cannot reassert the same patent infringement claims under US6993658B1 against Wells Fargo & Co. or Wells Fargo Bank, N.A. arising from this action. It provides Wells Fargo with permanent protection against re-litigation of these specific claims.
Yes. Case No. 2:22-cv-00217 was a member case within a series of consolidated proceedings in the Eastern District of Texas. The Lead Case, No. 2:22-cv-212, remained open when this member case was closed in January 2024, indicating Dynapass was pursuing authentication patent claims against additional defendants simultaneously.
The case was filed in the U.S. District Court for the Eastern District of Texas — a jurisdiction historically favored by NPE plaintiffs for its patent-friendly local rules and trial timelines. Filing multiple consolidated cases there is consistent with a coordinated NPE licensing and litigation strategy targeting the financial services sector.
