Case Overview
The Parties
⚖️ Plaintiff
A patent-holding entity asserting rights in data security and digital access management technologies, known for its strategic patent assertions.
🛡️ Defendant
A federally chartered financial institution, accused of patent infringement through its deployment of enterprise data protection products.
Patents at Issue
This case involved four U.S. patents asserted against data security and access management technologies. These patents collectively span a technology lineage traceable through multiple continuation and related applications, suggesting a coordinated prosecution strategy:
- • US10250639B2 — Data security and access management
- • US10182073B2 — Secure data storage structures
- • US9734169B2 — Digital access management
- • US9015301B2 — Authentication frameworks

The Verdict & Legal Analysis
Outcome
The case concluded with a Stipulated Motion to Dismiss With Prejudice jointly filed by both parties and granted by the court on January 5, 2026. This means all claims brought by Plaintiff Digital Doors, Inc. were dismissed with prejudice, barring future re-filing against Western Alliance Bank. Defendant’s counterclaims were dismissed without prejudice as moot.
No damages award, royalty figure, or injunctive relief was issued, and each party bore its own costs and attorney’s fees. This outcome strongly signals a negotiated resolution before substantive claim construction or trial proceedings.
Key Legal Issues
This case offers a textbook illustration of how patent assertion entity (PAE) litigation against financial institutions often resolves. The relatively compressed 305-day timeline and the stipulated dismissal mechanism indicate that the parties likely reached a confidential settlement. The core legal issues, though not adjudicated, revolved around whether Western Alliance Bank’s deployment of Dell’s enterprise data protection products, including the Sheltered Harbor Solution, infringed the asserted data security patents.
The dismissal with prejudice provides finality for the defendant on these specific claims, while the patents remain in force for potential assertion against other parties.
