PACid Technologies v. USAA FSB: Six FIDO Auth Patents, Dismissed With Prejudice
PACid Technologies, LLC asserted six US patents covering FIDO-ready authentication systems against USAA Federal Savings Bank in the Western District of Texas. After 538 days of litigation — and a pending IPR stay motion — the parties jointly stipulated to dismiss all of PACid’s claims with prejudice, each side bearing its own costs.
Six FIDO auth patents, one pending IPR stay, and a bilateral exit
On March 27, 2024, PACid Technologies, LLC filed suit against USAA Federal Savings Bank in the Western District of Texas (Case No. 1:24-cv-00321), asserting infringement of six US patents — US10484344B2, US10044689B2, US10171433B2, US11070530B2, US9577993B2, and US9876771B2 — all directed at FIDO-ready authentication software and systems. USAA FSB, a major financial institution serving the military community, was accused of deploying FIDOReady software and a FIDO-Ready System that allegedly practiced the asserted claims.
The case closed on September 16, 2025, via a Joint Stipulation for Dismissal With Prejudice entered under Federal Rule of Civil Procedure 41. Judge David Alan Ezra ordered all of PACid’s infringement claims dismissed with prejudice — permanently barring PACid from re-filing the same claims against USAA FSB. USAA FSB’s counterclaims and defenses were dismissed without prejudice, preserving USAA FSB’s ability to revive those positions if warranted. Both parties were ordered to bear their own costs and fees.
The 538-day duration and the simultaneous denial as moot of USAA FSB’s opposed motion to stay pending inter partes review suggest the parties reached a resolution — likely a confidential settlement — before the IPR proceedings could materially alter the litigation posture. The public record does not disclose any financial terms, license grant, or royalty arrangement, so the commercial substance of the resolution remains unknown. The with-prejudice dismissal of PACid’s claims is the most consequential public fact: it signals a clean exit for USAA FSB from this specific action.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 joint stipulation: a consensual, bilateral exit
Under Federal Rule of Civil Procedure 41, parties may jointly stipulate to dismiss an action without a court order. Here, both PACid and USAA FSB signed the stipulation, making the dismissal self-executing upon filing. The court’s order confirms the agreed terms rather than adjudicating the merits — meaning no infringement finding was made in either direction. The asymmetric treatment (PACid’s claims with prejudice; USAA’s counterclaims without prejudice) reflects a negotiated outcome, not a default result.
Rule 41 — no merits adjudicationWith-prejudice dismissal bars PACid from re-filing against USAA FSB
Dismissal with prejudice of PACid’s claims operates as a final judgment on the merits for res judicata purposes. PACid cannot re-assert the six FIDO patents against USAA FSB in a future action based on the same accused products and conduct. However, the patents themselves remain in force and enforceable against other parties. This outcome is consistent with a settlement in which PACid received some consideration in exchange for a permanent covenant not to sue USAA FSB, though the public record does not confirm this.
Claims barred — patents surviveUSAA FSB exits cleanly; counterclaims preserved without prejudice
USAA FSB’s counterclaims — which may have included invalidity and non-infringement defenses — were dismissed without prejudice, meaning USAA FSB retains the theoretical right to revive them. In practice, with PACid’s claims permanently dismissed, those counterclaims have no live controversy to attach to regarding this defendant-plaintiff pair. USAA FSB also avoids any adverse merits ruling on the validity or infringement of PACid’s FIDO authentication patents, which could have precedential value against USAA FSB’s third-party interests.
Clean exit — no adverse rulingIPR stay denied as moot — what that signals for the patent’s durability
USAA FSB had filed an opposed motion to stay the litigation pending inter partes review of the asserted patents — a common defensive tactic suggesting it had initiated or was preparing IPR petitions challenging patent validity. The court’s denial of that motion as moot, rather than on the merits, means no validity determination was made in this forum. Other potential defendants facing PACid’s FIDO portfolio cannot rely on this case to assess claim strength; independent IPR or litigation analysis remains essential before any design-around or licensing decision.

Official order — verbatim text
The court’s order reflects a negotiated bilateral exit rather than any adjudication of infringement or validity. The asymmetric prejudice terms — PACid’s claims dismissed with prejudice, USAA FSB’s counterclaims without — are the operative commercial signal: PACid accepted a permanent bar on re-filing against this defendant, while USAA FSB preserved technical flexibility on its defenses. The mootness denial of the IPR stay confirms that no inter partes review outcome shaped this resolution, leaving the six FIDO patents’ claim validity entirely open for future defendants to contest.
US10484344B2 — FIDO-ready secure authentication systems and protocols
The six asserted patents — US10484344B2, US10044689B2, US10171433B2, US11070530B2, US9577993B2, and US9876771B2 — form a coherent portfolio directed at FIDO (Fast Identity Online) authentication systems and software. Filed across application numbers ranging from US15/195606 to US16/547459, the patents cover successive layers of FIDO-ready architecture: credential management, secure communication protocols, identity verification workflows, and access control mechanisms. The portfolio spans grants from 2017 through 2021, reflecting iterative claim development around a core authentication framework.
FIDO authentication has become foundational infrastructure for financial services, enterprise security, and consumer identity platforms. PACid’s portfolio targets the implementation layer — specifically FIDOReady software and systems — making it relevant to any institution that has deployed FIDO2, WebAuthn, or FIDO UAF compliant authentication. The six-patent breadth suggests PACid has crafted overlapping claim coverage to survive individual invalidation attempts, a common NPE portfolio strategy. Financial institutions, cloud identity providers, and authentication middleware vendors operating in this space face meaningful exposure until independent IPR or reexamination proceedings resolve the claims’ validity.
Should you run an FTO against PACid’s FIDO authentication patent portfolio?
Any organisation deploying FIDO-based authentication — including banks, fintechs, enterprise SaaS platforms, and identity-as-a-service providers — should treat PACid’s six-patent portfolio as a live enforcement risk. The USAA FSB case demonstrates that PACid is willing to file in W.D. Tex. and sustain litigation for 18 months before resolving. If your product roadmap includes FIDO2, WebAuthn, or FIDO UAF credential management, a targeted FTO analysis against US10484344B2, US11070530B2, and the four related patents is warranted before deployment or product launch.
PatSnap Eureka’s FTO Search Agent can map your product’s authentication workflow against the claim language of all six PACid patents simultaneously, flagging overlapping claim elements and identifying prosecution history estoppel or prior art that may limit enforceability. Eureka’s litigation monitoring layer will also alert your team if PACid files further actions asserting this portfolio — giving in-house counsel and R&D leaders the earliest possible signal to adjust design choices or initiate licensing conversations before litigation commences.

What this case signals for the FIDO authentication IP landscape
PACid’s six-patent FIDO portfolio remains active and enforceable. This resolution tells competitors and financial sector adopters almost nothing about claim validity.
PACid’s FIDO portfolio is still live — other financial institutions remain at risk
The with-prejudice dismissal is USAA FSB-specific. All six asserted patents — including US10484344B2 and US11070530B2 — remain in force. Banks, fintechs, and any enterprise deploying FIDO-based authentication should treat this case as a signal of active enforcement, not portfolio exhaustion. PACid has demonstrated a willingness to litigate in W.D. Tex. and to pursue defendants through the IPR motion stage before settling.
IPR validity questions were never resolved — do not assume the claims are robust
USAA FSB’s motion to stay pending IPR signals that it identified prior art or other grounds to challenge the asserted claims. Because the case settled before any IPR institution decision became public in this context, the validity of PACid’s FIDO claims remains an open question. Any party evaluating a license or design-around should conduct independent claim mapping and prior art analysis rather than relying on this case’s resolution as a validity signal.
PACid v USAA — key questions answered
A dismissal with prejudice of PACid’s claims operates as a final judgment on the merits for res judicata purposes. PACid cannot re-file the same infringement claims against USAA FSB based on the same six FIDO authentication patents and the FIDOReady System. The patents themselves remain valid and enforceable against other parties — only this specific plaintiff-defendant pair is permanently resolved.
The asymmetric treatment reflects the negotiated terms of the joint stipulation. With PACid’s claims permanently dismissed, there is no live controversy for USAA FSB’s counterclaims — typically invalidity and non-infringement — to attach to in this action. Dismissing them without prejudice preserves USAA FSB’s technical flexibility but has no practical consequence absent a future PACid filing, which is barred by the with-prejudice dismissal.
PACid asserted six US patents: US10484344B2, US10044689B2, US10171433B2, US11070530B2, US9577993B2, and US9876771B2. All cover aspects of FIDO-ready authentication systems and software. The accused product was USAA FSB’s FIDOReady Software and FIDO-Ready System. The patents span application filings from 2016 to 2018 with grants between 2017 and 2021.
USAA FSB filed an opposed motion to stay the litigation pending inter partes review of PACid’s FIDO patents (Dkt. No. 44). The court denied the motion without prejudice as moot following the joint stipulation for dismissal. This means no IPR institution decision or validity ruling was issued in connection with this case. The validity of PACid’s FIDO claims remains legally open and unresolved.
The public record does not disclose any financial consideration. The mutual own-costs order — each party bearing its fees and expenses — is consistent with either a clean walk-away or a confidential payment structured outside the court record. The with-prejudice dismissal of only PACid’s claims, combined with the own-costs arrangement, suggests the resolution was negotiated rather than unilaterally conceded, but the commercial terms remain entirely confidential.
