Digital Doors, Inc. v. PNC Bank — Dismissed With Prejudice After 190 Days
Digital Doors, Inc. filed a four-patent infringement action against PNC Bank National Association in the Eastern District of Texas, asserting patents covering secure digital information infrastructure and granular data storage controls. The parties jointly moved to dismiss with prejudice after approximately six months, with each side bearing its own costs — a resolution pattern consistent with a confidential settlement.
Four-patent data security action against major US bank ends at six months
Digital Doors, Inc. initiated this infringement action on 2 May 2024 in the Eastern District of Texas, asserting four patents — US10250639B2, US10182073B2, US9734169B2, and US9015301B2 — against PNC Bank National Association. The patents collectively cover digital information security infrastructure, granular data stores, data flow distribution controls, secure storage with content analysis and classification, and configurable filter-based segmental data architectures. The accused products relate to PNC Bank’s digital information infrastructure systems.
The case closed on 8 November 2024 via a Stipulated Motion to Dismiss with Prejudice, jointly filed by both parties (Dkt. No. 65). The court granted the motion in full, dismissing all claims and causes of action with prejudice. Crucially, the order specifies that each party is to bear its own costs, expenses, and attorneys’ fees — a term commonly associated with negotiated resolution rather than a unilateral plaintiff withdrawal. The with-prejudice designation permanently bars Digital Doors from re-asserting these specific claims against PNC Bank.
A resolution in 190 days — before significant claim construction or discovery disputes reached the public record — suggests the parties moved toward resolution relatively early in the litigation cycle. The mutual cost-bearing term and stipulated dismissal format are consistent with a confidential settlement, though the public record does not confirm financial terms or license scope. Whether PNC Bank obtained a license, a covenant not to sue, or achieved some other arrangement remains unknown from available filings.

Dismissed with prejudice: what the stipulated order means for both parties
Stipulated dismissal with prejudice bars all re-filing
A dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii) or by court order operates as a final adjudication on the merits. Digital Doors cannot re-file these same patent claims against PNC Bank in any US federal court. The stipulated nature — jointly filed by both parties — distinguishes this from a unilateral withdrawal and typically signals a negotiated resolution of the underlying dispute.
Rule 41 — final, no re-filingDigital Doors exits with prejudice — licensing outcome unconfirmed
For Digital Doors, the with-prejudice dismissal forecloses any future action against PNC Bank on these four patents. However, the mutual cost-bearing term suggests this was not a capitulation — plaintiffs who walk away without compensation typically accept an adverse cost order or simply file a notice of dismissal. The stipulated structure is consistent with Digital Doors having extracted value, potentially a license or lump-sum payment, though no public record confirms this.
Possible settlement — terms undisclosedPNC Bank avoids merits ruling — exposure on four patents resolved
PNC Bank exits without any court finding of infringement, validity, or invalidity. The absence of a merits ruling means the four asserted patents remain valid and enforceable as a matter of record — PNC Bank did not secure an invalidity judgment that would benefit the broader industry. The own-costs term means PNC avoided a fee-shifting outcome, though its litigation costs over 190 days with five defense attorneys across two firms will have been substantial.
No invalidity finding — patents surviveFour data security patents remain live threats for other financial institutions
Because the dismissal is bilateral and on the merits only as between these parties, Digital Doors retains the right to assert US10250639B2, US10182073B2, US9734169B2, and US9015301B2 against other defendants. Banks and fintech companies operating granular data store or secure information infrastructure systems should note that this portfolio appears active and commercially enforced. The E.D. Texas venue choice and Garteiser Honea representation are consistent with a serial enforcement strategy.

Official order — verbatim text
The court’s order closely follows the parties’ stipulation, granting dismissal with prejudice of all claims and causes of action and ordering each party to bear its own costs and fees. The ‘each party bears its own costs’ term is analytically significant — it rules out a fee-shifting outcome under 35 U.S.C. § 285 and is inconsistent with a purely voluntary plaintiff withdrawal. The denial of all pending relief as moot confirms no substantive rulings survived the dismissal, leaving the patent portfolio’s validity and claim scope entirely intact for future enforcement against other defendants.
US10250639B2 — Secure digital information infrastructure with granular data stores
The four asserted patents — US10250639B2, US10182073B2, US9734169B2, and US9015301B2 — span application filing dates from as early as App. No. 11/746440, indicating a portfolio built over multiple prosecution generations. Collectively, they cover methods and systems for managing digital information infrastructure with security-designated data flows, granular and segmental data stores, configurable filtering mechanisms, content analysis and classification, and distribution controls. This technical domain sits at the intersection of data governance, secure storage architecture, and access-controlled information management.
For financial institutions, these patents are strategically significant because modern banking data architectures — including cloud data lakes, tokenisation vaults, data classification engines, and permissioned data distribution systems — map conceptually onto the claimed inventions. Digital Doors’ decision to assert all four patents simultaneously against a major US bank suggests the portfolio was constructed with financial services infrastructure in mind. Any organisation operating segmental or granular data storage with access controls, particularly in regulated industries, should treat this family as a material FTO risk.
Should your team run an FTO against US10250639B2 and related patents?
R&D and product teams at banks, fintech companies, cloud data platform vendors, and enterprise data governance providers should assess their exposure to this four-patent family. If your architecture involves granular data stores, configurable access filters, content classification at ingestion, or segmental data routing with distribution controls, the claim language of these patents — particularly the earlier-priority US9015301B2 and US9734169B2 — warrants careful review. The E.D. Texas enforcement action against PNC Bank confirms these patents are actively monetised, not dormant.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of all four patents against your product architecture in minutes, identify prior art that may narrow claim scope, and flag prosecution history estoppel that could limit the doctrine of equivalents. With Digital Doors holding a portfolio of four related patents prosecuted across multiple application generations, a single-patent FTO is insufficient — Eureka analyses the full family simultaneously, giving your legal and product teams a defensible clearance analysis before you ship.

What this case signals for the financial data security IP landscape
A six-month E.D. Texas resolution with mutual cost-bearing suggests a live, commercially enforced data security portfolio targeting financial institutions.
E.D. Texas + Garteiser Honea signals a serial enforcement campaign
The combination of Eastern District of Texas venue, Garteiser Honea as plaintiff counsel, and a four-patent data security portfolio is consistent with a structured enforcement program. Other banks and fintech operators with digital information infrastructure and granular data store architectures should assess their exposure to this patent family before receiving a demand letter.
No invalidity ruling means the patent family retains full enforceability
PNC Bank’s exit via stipulated dismissal — rather than an IPR petition or declaratory judgment — leaves all four patents fully valid and enforceable. Competitors cannot rely on this litigation to weaken the portfolio. Companies in the financial services and data infrastructure sectors should treat these patents as active threats until a merits-based validity ruling is obtained.
Digital v PNC — key questions answered
The dismissal with prejudice in Case No. 2:24-cv-00317 means Digital Doors, Inc. is permanently barred from re-asserting the four patents-in-suit against PNC Bank National Association. However, the patents remain valid and enforceable against all other defendants, and Digital Doors retains full rights to pursue infringement actions against third parties.
Digital Doors asserted four patents: US10250639B2, US10182073B2, US9734169B2, and US9015301B2. These patents cover digital information security infrastructure, granular and segmental data stores, data flow distribution controls, configurable filters, and information management tools with content analysis and classification capabilities.
The mutual cost-bearing term does not legally confirm a financial settlement, but it is consistent with one. It rules out a fee-shifting outcome under 35 U.S.C. § 285 and is atypical of a pure plaintiff walkaway. The stipulated — rather than unilateral — nature of the dismissal further suggests the parties reached a negotiated resolution, though terms remain undisclosed from the public record.
Yes. The dismissal with prejudice applies only as between Digital Doors and PNC Bank. All four asserted patents survive fully valid and enforceable against other defendants. The E.D. Texas venue, Garteiser Honea representation, and multi-patent assertion pattern are consistent with a structured enforcement campaign. Financial institutions and fintech companies with data governance or segmental storage architectures should conduct FTO analysis on this portfolio.
No. The case resolved via stipulated dismissal with prejudice at Dkt. No. 65, before any claim construction order or merits ruling entered the public record. The court denied all pending relief as moot. This means no judicial determination of validity, invalidity, infringement, or non-infringement was made, leaving the patents’ legal status entirely unchanged.
