Digital Doors, Inc. v. Origin Bank — Dismissed With Prejudice in 57 Days
Digital Doors, Inc. asserted four cybersecurity patents against Origin Bank’s Sheltered Harbor compliant systems in the Eastern District of Texas. The plaintiff voluntarily dismissed the case with prejudice just 57 days after filing — a timeline that suggests a rapid resolution, whether through settlement or strategic withdrawal, before any substantive court proceedings.
Four cybersecurity patents, one bank, and a 57-day exit in East Texas
On May 2, 2024, Digital Doors, Inc. filed a patent infringement complaint against Origin Bank in the Eastern District of Texas (Case No. 2:24-cv-00316), asserting four US patents — US10250639B2, US10182073B2, US9734169B2, and US9015301B2 — in connection with Origin Bank’s alleged use of Sheltered Harbor compliant systems. Sheltered Harbor is a financial-sector data protection standard designed to ensure account data survivability during cyberattacks.
The case closed on June 28, 2024, just 57 days after filing, when Digital Doors filed a Notice of Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Critically, the dismissal was expressly with prejudice, meaning Digital Doors permanently relinquished its right to re-assert these four patents against Origin Bank on the same claims. The court accepted the notice and denied all other pending relief as moot.
A with-prejudice voluntary dismissal at this early stage — before any defendant answer or substantive motion — typically signals either a private settlement reached off the record or a strategic reassessment by the plaintiff. The public record does not disclose any financial terms or licensing agreement. The speed of resolution, combined with the finality of the with-prejudice designation, leaves open the question of whether Digital Doors received consideration from Origin Bank.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: plaintiff’s unilateral right to exit
Under FRCP 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case without a court order before the defendant files an answer or motion for summary judgment. Digital Doors exercised this right and elected to dismiss with prejudice — a stronger finality than the rule strictly requires. The court accepted and acknowledged the notice, closing the case with no merits adjudication.
No merits ruling issuedWith prejudice vs. without prejudice: a critical distinction
A dismissal with prejudice operates as a final judgment on the merits, permanently barring Digital Doors from re-filing the same claims against Origin Bank on these four patents. A dismissal without prejudice would have preserved that option. The Notice explicitly stated ‘WITH PREJUDICE,’ and the court’s order reflects that designation. The public record does not indicate whether this finality was the product of a negotiated agreement or a unilateral decision.
Re-filing against Origin Bank barredOrigin Bank exits without admitting infringement or invalidity
Because the dismissal occurred before any substantive proceedings, Origin Bank made no admissions on infringement, validity, or claim scope. The with-prejudice designation protects Origin Bank from this specific plaintiff on these specific claims going forward. However, the patents themselves remain in force and could be asserted against other financial institutions operating Sheltered Harbor compliant infrastructure.
No admissions; patents still liveSheltered Harbor compliance creates a recurring patent exposure vector
Digital Doors’ assertion targets a compliance standard widely adopted across the US banking sector. Other financial institutions using Sheltered Harbor compliant systems may face similar assertions from these or related patents. The rapid with-prejudice exit suggests the enforcement strategy for this portfolio is still developing. Banks and fintech operators in the data resilience and secure vault space should monitor Digital Doors’ patent activity and assess FTO exposure proactively.

Official order — verbatim text
The court’s order is procedural rather than substantive: it accepts Digital Doors’ Rule 41(a)(1)(A)(i) notice and formalises the with-prejudice designation the plaintiff itself chose. No claim construction, infringement finding, or validity ruling was issued. For Origin Bank, the order provides a permanent defence against re-litigation of these claims. For the broader market, the absence of any merits ruling means the four asserted patents carry no court-tested claim scope — strengthening the case for proactive FTO analysis by other potential targets.
US10250639B2 and 3 co-asserted patents — secure data vault and resilience systems
The four asserted patents — US10250639B2 (App. 14/597345), US10182073B2 (App. 14/597314), US9734169B2 (App. 13/900728), and US9015301B2 (App. 11/746440) — span two distinct filing generations, with the oldest application (11/746440) suggesting priority claims reaching back considerably earlier than the continuation filings. The patents appear to cover secure data management, access control, and resilient data vault architectures of the type deployed in Sheltered Harbor compliant financial infrastructure.
Sheltered Harbor is an industry-led initiative requiring participating financial institutions to maintain encrypted, isolated account data vaults capable of surviving a cyberattack. By targeting compliance with this specific standard, Digital Doors’ portfolio is positioned to assert against a large, identifiable class of defendants — any FDIC-insured or participating bank that has implemented Sheltered Harbor. The portfolio’s multi-patent, multi-generation structure suggests it was assembled for sustained enforcement rather than a single dispute.
Should your bank run an FTO against US10250639B2 and the Digital Doors portfolio?
Any financial institution operating Sheltered Harbor compliant data vault infrastructure should treat this litigation as a direct signal. Digital Doors has demonstrated willingness to file in the Eastern District of Texas — a historically plaintiff-friendly venue — and the four asserted patents cover technology that is functionally indistinguishable across many Sheltered Harbor implementations. The with-prejudice exit against Origin Bank does not extinguish risk for other institutions.
PatSnap Eureka’s FTO Search Agent can map each claim of US10250639B2, US10182073B2, US9734169B2, and US9015301B2 against your institution’s specific data vault and access control architecture, flagging which claims present the highest overlap risk. Eureka also tracks continuation filings from these application families, providing early warning if Digital Doors expands its portfolio into adjacent claim territory covering data resilience or secure financial data management.

What this case signals for the financial cybersecurity IP landscape
A four-patent assertion resolved in under two months raises questions about enforcement strategy and the value of early settlement in compliance-driven tech sectors.
Early dismissals with prejudice often signal undisclosed settlement terms
When a plaintiff dismisses with prejudice this quickly — before any answer is filed — it typically reflects a negotiated resolution rather than pure abandonment. The financial terms, if any, remain private. Origin Bank’s engagement of Vinson & Elkins suggests it was prepared to defend, which may have accelerated resolution.
Sheltered Harbor compliance may be the next patent assertion flashpoint in banking
Digital Doors’ choice to target Sheltered Harbor compliant systems is notable: it links patent exposure directly to a regulatory and industry compliance standard. Any bank meeting Sheltered Harbor requirements could theoretically face the same four patents. IP teams at financial institutions should evaluate their exposure across US10250639B2 and the three co-asserted patents now.
Digital v Origin — key questions answered
The dismissal with prejudice bars Digital Doors from re-suing Origin Bank on the same four patents. However, it has no binding effect on other financial institutions. Banks operating Sheltered Harbor compliant systems remain exposed to assertion of US10250639B2, US10182073B2, US9734169B2, and US9015301B2 and should conduct independent FTO analysis.
Digital Doors asserted four patents: US10250639B2, US10182073B2, US9734169B2, and US9015301B2. All relate to secure data management and access control technologies and were asserted in connection with Origin Bank’s use of Sheltered Harbor compliant systems.
The case closed 57 days after filing, before any answer was filed by the defendant. This timeline is consistent with either a private settlement or a strategic withdrawal. The public record is silent on financial terms. The with-prejudice designation — stronger than required under Rule 41(a)(1)(A)(i) — suggests the exit was negotiated rather than purely voluntary.
Sheltered Harbor is a financial industry data protection standard requiring banks to maintain encrypted, isolated data vaults resilient to cyberattacks. Digital Doors’ assertion targets banks implementing this standard, effectively linking patent exposure to regulatory compliance adoption. This makes the portfolio potentially assertable against a broad class of participating financial institutions.
Yes. The with-prejudice dismissal only bars Digital Doors from re-asserting these patents against Origin Bank. The patents remain in force, and Digital Doors retains the right to assert them against other financial institutions or technology providers. Monitoring Digital Doors’ litigation activity and continuation filings from the asserted application families is advisable for institutions in the sector.
