Case Overview
The Parties
⚖️ Plaintiff
Operates as a patent assertion entity (PAE), acquiring patent portfolios and generating revenue through licensing and litigation rather than direct product commercialization.
🛡️ Defendant
Globally recognized financial services corporation with extensive customer communication infrastructure, including call centers, automated routing systems, and digital customer service platforms.
The Patents at Issue
This infringement action centered on five U.S. patents covering intelligent communication routing and telephony systems. These patents are registered with the U.S. Patent and Trademark Office (USPTO) and are often asserted in cases involving sophisticated customer service and call-routing infrastructure.
- • US9456086B1 — Intelligent communication routing systems
- • US10491748B1 — Advanced routing methodology
- • US7269253B1 — Telephony control with intelligent call routing
- • US7023979B1 — Entity-matching in auction-based systems
- • US10237420B1 — Routing system enhancements

The Verdict & Legal Analysis
Outcome
The Court granted Plaintiff Patent Armory, Inc.’s Notice of Voluntary Dismissal Without Prejudice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i). No damages were awarded, no injunctive relief was granted or denied, and no merits determination was made. The Clerk was instructed to close the case.
Specific settlement terms, if any exist, were not disclosed in the public record. The voluntary dismissal just six days after filing reflects a strategic decision rather than a full litigation outcome, leaving the door open for future assertion.
Key Legal Issues
Because the case concluded before any substantive judicial engagement, there is no claim construction ruling, infringement analysis, or validity challenge to examine on the merits. The legal significance lies entirely in the procedural posture and strategic context:
Rule 41(a)(1)(A)(i) Implications: This provision is a powerful plaintiff tool. By dismissing before the defendant answers, Patent Armory retains the right to refile the same claims against American Express or any other party. There is no adjudication on the merits, no res judicata bar, and — critically — no attorney’s fees exposure under 35 U.S.C. § 285 (exceptional case standard) triggered by a dismissal at this stage without further litigation conduct.
Pre-Answer Timing as Strategy: The decision to dismiss within six days of filing, before American Express even engaged defense counsel on the record, is a hallmark of certain PAE litigation strategies. It may reflect: (1) receipt of a licensing communication or settlement offer; (2) a decision to refile in federal court in a different district; (3) reassessment of claim strength following filing; or (4) a tactical “notice shot” — establishing awareness of the patents for future licensing negotiations.
For the five patents at issue — all involving intelligent routing, telephony control, and entity-matching — this case signals continued assertion activity in the telecom-meets-fintech patent space. Companies operating automated customer routing infrastructure should note these patent numbers specifically.

Five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1, covering intelligent communication routing and telephony control systems.
Plaintiff filed a voluntary dismissal without prejudice under FRCP 41(a)(1)(A)(i) just six days after filing, before defendant answered. This preserves plaintiff’s right to refile and suggests a strategic or settlement-driven decision rather than a merits determination.
It signals continued PAE assertion activity in this space. Companies operating intelligent call routing infrastructure should prioritize FTO analyses and consider proactive PTAB review of the asserted patents.
