DigitalDoors v. Centennial Bank: Four-Patent Data Security Suit Dismissed With Prejudice
DigitalDoors, Inc. filed suit in the Eastern District of Texas asserting four patents covering digital information security infrastructure, granular data stores, and content classification tools against Centennial Bank. The case closed in just 121 days — dismissed with prejudice, with each party bearing its own costs.
Four Data Security Patents, One Fast Exit: Reading the E.D. Texas Dismissal
On September 25, 2024, DigitalDoors, Inc. filed an infringement action in the Eastern District of Texas (Case No. 2:24-cv-00779) against Centennial Bank, asserting four issued US patents — US10250639B2, US10182073B2, US9734169B2, and US9015301B2. The patents collectively cover digital information security infrastructure, granular data stores, content classification tools, and variable configurable filters for segmental data management. The asserted products span a broad platform of information infrastructure management tooling.
The case closed on January 24, 2025, just 121 days after filing. The Court granted a motion to dismiss all claims and causes of action with prejudice. Critically, each party was ordered to bear its own costs, expenses, and attorneys’ fees, and all pending relief requests were denied as moot. A dismissal with prejudice is a final adjudication on the merits — DigitalDoors is barred from reasserting these specific claims against Centennial Bank in federal court.
The 121-day lifespan and mutual cost-bearing arrangement are consistent with a negotiated resolution — possibly a settlement reached before substantive litigation commenced — though the public record does not confirm this. No claim construction, Markman hearing, or merits ruling appears in the record. What drove the swift closure remains unknown from publicly available filings, but the with-prejudice designation ensures finality for Centennial Bank on these four patents.

Dismissed with prejudice: what the court’s order means for both parties
Dismissal with prejudice bars refiling on these claims
A dismissal with prejudice operates as a final judgment on the merits. Unlike a without-prejudice dismissal, DigitalDoors cannot refile these specific patent claims against Centennial Bank in any federal court. The Court’s order explicitly dismissed all claims and causes of action asserted between the parties, leaving no claims alive. The motion granting the dismissal was not opposed on the record, which is typically consistent with a jointly agreed resolution.
Final — no refiling permittedDigitalDoors loses the right to refile — but no adverse merits ruling
For DigitalDoors, the with-prejudice dismissal forecloses any future action against Centennial Bank on these four patents. However, the absence of a claim construction ruling or invalidity finding means the patents themselves are not invalidated. DigitalDoors retains the right to assert the same patents against different defendants. The mutual cost-bearing terms suggest no monetary judgment was entered against DigitalDoors.
Patents intact — action against others possibleCentennial Bank achieves finality on all four asserted patents
Centennial Bank secured a permanent bar against DigitalDoors reasserting these four data security patents in litigation. No damages, injunction, or royalty obligation appears in the public record. The own-costs order means Centennial Bank absorbed its own defense fees — likely a favourable result if a licence or payment was negotiated privately. The bank is insulated from re-exposure to this specific patent portfolio from this plaintiff.
Full finality — no damages on recordData security infrastructure patents remain a live enforcement risk for financial sector
The rapid resolution without a merits ruling leaves the four DigitalDoors patents in an ambiguous state for the broader financial services market. Banks and fintech platforms operating granular data store or content classification infrastructure cannot rely on this dismissal as precedent for non-infringement or invalidity. DigitalDoors’ patent portfolio remains available for assertion against other defendants, and the Eastern District of Texas remains an active venue for similar claims.

Official order — verbatim text
The Court’s order is unambiguous in its finality: all claims and causes of action are dismissed with prejudice, pending relief denied as moot, and costs allocated mutually. The phrase ‘having considered the Motion’ indicates a formal motion — likely a joint stipulation — was filed and granted without opposition. No merits determination, damages finding, or injunction forms part of the record. The with-prejudice designation confers res judicata effect solely as between DigitalDoors and Centennial Bank, and does not affect the patents’ validity or enforceability against third parties.
US10250639B2, US10182073B2, US9734169B2, US9015301B2 — Data Security Infrastructure
The four asserted patents — US10250639B2, US10182073B2, US9734169B2, and US9015301B2 — derive from application families filed between 2007 and 2015, suggesting a multi-generational prosecution strategy. The portfolio covers digital information security infrastructure including security-designated data flows, granular data store architectures, content analysis and classification tooling, and variable configurable filters for segmented data management. These claims sit at the intersection of data security, enterprise information governance, and access-controlled storage.
For the financial services sector, these patents are strategically significant: banks and fintech platforms routinely deploy exactly the kind of tiered, classified data storage and access-control infrastructure described in the claims. The breadth of the portfolio across four patents and multiple application families increases the difficulty of designing around any single claim set. The absence of any invalidity or claim construction ruling from this case means the patents retain full presumptive validity, and any organisation operating comparable data security architecture should assess exposure proactively.
Should you run an FTO against US10250639B2 and the DigitalDoors portfolio?
Any organisation deploying digital information security infrastructure with granular data stores, content classification layers, or segmented access-control architectures — particularly in financial services, enterprise SaaS, or regulated data environments — should consider a freedom-to-operate assessment against these four patents. The claims have not been narrowed by any court, and the portfolio’s application filing history spanning 2007–2015 suggests broad coverage across multiple technology generations.
PatSnap Eureka’s FTO Search Agent can map each claim family against your product architecture, identify prior art that may support invalidity arguments, and flag design-around opportunities across all four patent numbers simultaneously. Given that DigitalDoors’ portfolio remains active and no adverse ruling constrains future assertions, proactive FTO analysis is the most effective risk-mitigation step available to product and IP teams in this space.

What this case signals for the data security IP landscape in financial services
A swift with-prejudice dismissal in E.D. Texas — without any merits ruling — leaves these four patents dangerous for the sector.
With-prejudice dismissal without merits ruling leaves patents fully enforceable elsewhere
DigitalDoors’ four patents covering data security infrastructure and granular data stores have not been adjudicated for validity or infringement scope. Banks, fintechs, and enterprise SaaS platforms operating similar data classification or segmented storage architecture should treat these patents as active litigation risk, regardless of this case’s outcome.
E.D. Texas remains a preferred venue for data security patent assertions against financial institutions
The Eastern District of Texas continues to attract patent infringement filings targeting financial services defendants. The 121-day lifespan here is consistent with early settlement or licensing resolution — a pattern that increases the cost-effectiveness of rapid assertion strategies. IP teams at banks should monitor the DigitalDoors portfolio for further downstream filings.
DIGITALDOORS v Centennial — key questions answered
The dismissal with prejudice in Case No. 2:24-cv-00779 means all patent infringement claims asserted by DigitalDoors against Centennial Bank are permanently barred from refiling. The Court’s order operates as a final judgment between these specific parties. It does not affect the validity of the four DigitalDoors patents or their enforceability against any other defendant.
DigitalDoors asserted four US patents: US10250639B2 (digital information infrastructure for security-designated data with granular stores), US10182073B2 (data flow distribution controls), US9734169B2 (content analysis, classification and secure storage), and US9015301B2 (variable configurable filters and segmental data stores). The applications were filed between 2007 and 2015.
The case closed in 121 days — well below the median E.D. Texas patent litigation timeline. The Court granted an unspecified motion, with each party bearing its own costs and no damages on record. This pattern is consistent with a privately negotiated resolution or licensing agreement, though the public record does not confirm the specific terms or whether consideration was exchanged.
No. The with-prejudice dismissal only bars DigitalDoors from reasserting these four patents against Centennial Bank specifically. The patents remain valid and enforceable. DigitalDoors retains full rights to assert US10250639B2, US10182073B2, US9734169B2, and US9015301B2 against any other party in any appropriate forum.
The order that each party bear its own costs, expenses, and attorneys’ fees means no fee-shifting occurred under 35 U.S.C. § 285 or any other provision. Neither party was found to have litigated exceptionally or in bad faith. This outcome is commercially neutral on costs and is consistent with a voluntary resolution reached before substantial litigation expense accumulated.
