Digital Doors v. IBC Bank: Four Security Patents, 92-Day Settlement
Digital Doors, Inc. asserted four U.S. patents covering digital information security infrastructure and granular data classification against IBC Bank in the Western District of Texas. The case resolved in 92 days via a written agreement, with all claims dismissed with prejudice — each side bearing its own attorneys’ fees.
Four Data Security Patents, One Regional Bank, and a Swift Texas Resolution
Digital Doors, Inc. filed suit on March 6, 2025 in the Western District of Texas against International Bancshares Corp., doing business as IBC Bank, asserting infringement of four U.S. patents: US10250639B2, US10182073B2, US9734169B2, and US9015301B2. The patents collectively cover a layered information security infrastructure, including secure data storage, content analysis and classification, configurable data filters, and segmental data stores — technologies that are directly relevant to how financial institutions manage, segment, and protect customer data.
The case closed on June 6, 2025 — just 92 days after filing — when the court granted a motion to dismiss all claims with prejudice, subject to a written agreement between the parties. The with-prejudice designation means Digital Doors cannot re-file the same claims against IBC Bank. Notably, the court’s order directed each side to bear its own fees and costs, suggesting a negotiated resolution rather than a contested ruling on the merits.
The speed of resolution — under three months — is consistent with a settlement reached shortly after service or initial case management, before significant discovery costs accumulated. The public record does not disclose the financial terms of the written agreement. What remains unknown is whether IBC Bank obtained a license to the asserted patents or simply secured a release, a distinction with meaningful implications for Digital Doors’ broader assertion strategy against other financial-sector defendants.

Dismissed with prejudice: what the court order means for both parties
Dismissal with prejudice bars any re-filing of these claims
A dismissal with prejudice is a final adjudication on the merits for procedural purposes — Digital Doors permanently relinquishes the right to reassert these four patent claims against IBC Bank in any future action. The order was entered pursuant to a written agreement, which is the standard mechanism for a negotiated patent settlement where both parties want finality but wish to keep financial terms confidential.
Permanent bar on re-filingDigital Doors exits with confidential terms, loses right to refile
By agreeing to dismissal with prejudice, Digital Doors accepted a permanent close to this specific action. The upside is that any negotiated consideration — licensing fees, a one-time payment, or other commercial terms — remains protected by the confidentiality of the written agreement. Digital Doors retains ownership of the four patents and may continue asserting them against other defendants in the financial services sector.
Confidential settlement likelyIBC Bank secures finality; each side bears its own legal costs
IBC Bank achieved a with-prejudice dismissal, meaning it faces no further litigation risk from Digital Doors on these four patents in relation to this dispute. The cost-bearing order — each side paying its own fees — is consistent with a mutual settlement rather than a contested win. Whether IBC Bank secured an ongoing license or merely a covenant not to sue is not disclosed in the public record, which matters for how the bank structures future technology deployments.
No fee-shifting; finality securedRegional banks face continued exposure to data infrastructure patent assertions
The rapid resolution suggests both parties found early settlement commercially rational. For other financial institutions using similar data segmentation, classification, or secure storage architectures, Digital Doors’ patent portfolio remains active and asserted. The 92-day timeline signals that Digital Doors’ litigation strategy may favour volume and speed over prolonged contested trials, which typically signals a well-resourced assertion campaign targeting multiple defendants across the banking sector.

Official order — verbatim text
The court’s order is a consent dismissal with prejudice entered at the plaintiff’s motion and expressly conditioned on a written agreement between the parties. This formulation is the standard W.D. Texas mechanism for a negotiated patent settlement: the with-prejudice designation gives the defendant res judicata protection against re-assertion of the same claims, while the written agreement allows the parties to keep financial terms off the public docket. The cost-bearing clause — each party responsible for its own fees — confirms no prevailing party determination was made, consistent with mutual commercial resolution rather than any merits adjudication.
US10250639B2 — Digital Information Security Infrastructure Patent Family
US10250639B2, filed from application US14/597345, protects a digital information infrastructure and method for security-designated data with granular data stores — covering architectures that enforce security designations at a granular, segment-level rather than at the system perimeter. The family spans four patents originating from applications filed as early as US11/746440, placing the earliest priority in the mid-2000s when enterprise data segmentation was an emerging field. The patents collectively address how data flows through secure storage layers, content analysis, classification engines, and configurable filters.
For financial institutions, these patents are strategically significant because the claimed architectures closely resemble the tiered data management systems that modern banks use to comply with data protection regulations, segment customer information, and enforce access controls across distributed infrastructure. The breadth of the four-patent family — spanning classification, segmentation, filtration, and distribution controls — means that a single banking platform may face exposure across multiple claim sets simultaneously, raising the cost of any invalidity or non-infringement defense. Other banks using comparable architectures should treat this portfolio as an active litigation risk.
Should your organisation run an FTO against US10250639B2 and its family?
Any financial institution, fintech, or enterprise software vendor operating data classification systems, segmented data stores, or content-based access controls should evaluate exposure against this four-patent family before deploying or expanding such infrastructure. The patents’ language — granular data stores, configurable filters, segmental access — maps broadly to architectures used in core banking, cloud data governance, and regulatory compliance platforms. The fact that Digital Doors has already commenced and rapidly resolved litigation in W.D. Texas suggests an active assertion campaign.

What this case signals for the financial data security IP landscape
A fast, confidential resolution in W.D. Texas suggests Digital Doors is running a systematic assertion strategy — and regional banks are in scope.
Speed of resolution suggests pre-trial settlement pressure is the strategy
At 92 days, this case closed before meaningful discovery. Plaintiff’s counsel — Garteiser Honea PLLC — is a specialist Texas patent litigation firm known for high-volume assertion. This pattern typically signals demand letters preceding suit and structured settlement offers that make early resolution commercially attractive relative to litigation cost.
Four-patent assertion broadens invalidity attack surface but raises licensing value
Asserting four related patents simultaneously increases the cost of an IPR or invalidity defense for defendants, but it also signals that the plaintiff views the portfolio as a commercial licensing asset. Financial institutions evaluating their exposure should audit whether their data classification, segmentation, and secure storage systems overlap with the claim scope of US10250639B2 and its family members.
Digital v International — key questions answered
Digital Doors, Inc. filed a patent infringement action against International Bancshares Corp. (IBC Bank) in the Western District of Texas on March 6, 2025, asserting four patents covering data security infrastructure. The case was dismissed with prejudice on June 6, 2025 — 92 days later — pursuant to a written agreement between the parties, with each side bearing its own costs.
Digital Doors asserted four U.S. patents: US10250639B2 (digital information security with granular data stores), US10182073B2 (data processing tools with distribution controls), US9734169B2 (management tools with secure storage and content classification), and US9015301B2 (management tools with configurable filters and segmental data stores). The patents span a family of information infrastructure security technologies.
A dismissal with prejudice permanently bars Digital Doors from re-asserting the same patent claims against IBC Bank in any future action. The order is effectively a final judgment for res judicata purposes against that specific defendant. However, Digital Doors retains ownership of all four patents and may continue to assert them against other defendants.
The court’s order does not disclose the financial or substantive terms of the written agreement. The dismissal was expressly made ‘subject to the terms of a written agreement between the parties,’ which is standard confidential settlement language. Whether IBC Bank received a license, a covenant not to sue, or another form of resolution is not determinable from the public record.
Digital Doors was represented by Randall T. Garteiser, Christopher A. Honea, and M. Scott Fuller of Garteiser Honea PLLC — a Texas-based firm specialising in patent litigation. IBC Bank was represented by Jason S. Jackson of Kutak Rock LLP. The fee-bearing order — each party responsible for its own costs — was consistent with a negotiated mutual resolution.
