Patent Armory v. American Heart Association: Five Call-Routing Patents, Dismissed in 29 Days
Patent Armory, Inc. asserted five patents spanning intelligent call routing, telephony control, and auction-based entity matching against the American Heart Association. The case was voluntarily dismissed without prejudice just 29 days after filing — before the defendant filed any answer — leaving all claims legally open.
A Pre-Answer Voluntary Dismissal Across Five Call-Routing Patents
On 18 September 2024, Patent Armory, Inc. filed suit against American Heart Association, Inc. in the Illinois Northern District Court before Judge Martha M. Pacold, asserting infringement of five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The patents collectively cover intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity-matching methods — technologies with broad applicability to customer contact and donor-engagement platforms.
On 17 October 2024 — just 29 days after filing — Patent Armory voluntarily dismissed the action without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). That procedural rule permits a plaintiff to dismiss unilaterally, as of right, provided the defendant has not yet served an answer or moved for summary judgment. The public record confirms neither had occurred. A dismissal without prejudice does not adjudicate the underlying merits; Patent Armory retains the right to re-file the same claims in any competent forum, subject to any applicable statute of limitations.
A 29-day window from filing to dismissal is notably short and suggests the parties may have reached a private resolution, or that Patent Armory elected to withdraw following initial defendant contact — neither scenario is confirmed by the public record. No costs, fees, or injunctive relief were ordered. The absence of any defence filing means the strength of the asserted patents was never tested in this proceeding, and the American Heart Association carries no estoppel from this case.

Voluntarily dismissed: what the Rule 41 exit means for both parties
FRCP 41(a)(1)(A)(i): plaintiff’s unilateral right of exit
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because the American Heart Association had not yet responded, Patent Armory exercised this right unilaterally. No judicial approval was required, and no merits determination was made. The dismissal is self-executing upon filing.
No court order neededWithout prejudice — but the public record does not say why
A dismissal ‘without prejudice’ preserves the plaintiff’s right to re-file the same claims; one ‘with prejudice’ extinguishes them permanently. The notice filed here explicitly states ‘without prejudice,’ so refiling remains possible. However, the public record is silent on whether a settlement or licensing agreement was reached privately. Practitioners should not assume either scenario without further diligence; the filing itself is neutral on commercial terms.
Refiling legally possibleAHA exits without estoppel — but exposure persists
Because no answer was filed and no merits ruling was made, the American Heart Association receives no invalidity finding, no non-infringement ruling, and no claim construction order from this proceeding. The organisation is not estopped from raising any defence in a future action. However, the dismissal without prejudice means Patent Armory retains the right to re-assert the same five patents, making continued exposure a live consideration for AHA’s IP counsel.
No estoppel; exposure remainsFive patents still active — sector-wide risk for call-routing platforms
All five asserted patents remain in force following dismissal. Organisations deploying intelligent call-routing, IVR, or auction-based lead-matching systems — particularly non-profits and contact-centre operators — should note that Patent Armory’s portfolio was not invalidated or licensed away on the public record. The short litigation window is consistent with a broader licensing campaign where pre-answer resolution is the norm rather than the exception.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) and expressly confirms the defendant had not answered or moved for summary judgment — the procedural prerequisites for a unilateral plaintiff exit. The ‘without prejudice’ designation is legally significant: it leaves the merits of all five patent claims entirely unadjudicated. Neither validity, infringement, nor claim scope was considered by the court. Patent Armory retains full enforcement rights against the AHA and any other party, and no issue preclusion arises from this filing.
US9456086B1 — Intelligent Communication Routing System
The five asserted patents cluster around two core technology areas: intelligent call and communication routing (US9456086B1, US10491748B1, US7269253B1, US7023979B1) and auction-based entity matching applicable to inbound call distribution (US10237420B1). The application dates span from the early 2000s through the mid-2010s, reflecting iterative development of routing logic as telephony migrated from hardware PBX to software-defined and cloud-based architectures. US7023979B1, one of the earlier filings, covers foundational telephony control methods that underpin the later continuation-style claims.
For the contact-centre and communications sector, this portfolio presents meaningful risk because intelligent routing is now embedded in virtually every enterprise inbound communications stack — including donor-management systems used by large non-profits like the AHA. The auction-matching patent (US10237420B1) is particularly notable: auction-based call routing is widely deployed in insurance, financial services, and healthcare lead-generation platforms. Any organisation licensing third-party call-routing software or operating a multi-queue inbound system should assess claim overlap before assuming design freedom.
Should you run an FTO against US9456086B1 and the Patent Armory call-routing portfolio?
If your organisation operates an intelligent inbound call-routing system, uses auction or bid-based call distribution, or deploys IVR with dynamic routing logic, the five patents asserted in this case are directly relevant to your freedom-to-operate posture. This applies to software vendors, SaaS contact-centre providers, CRM platforms with telephony integrations, and large non-profits or enterprises managing high-volume inbound communications.
PatSnap Eureka’s FTO Search Agent can map claim language from US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 against your product architecture, identify prior art that could support invalidity arguments, and flag any continuation or divisional applications that may extend this portfolio’s enforceability window. Running an FTO now — before a demand letter arrives — is significantly lower cost than reactive litigation defence.

What this case signals for the call-routing and telephony IP landscape
A 29-day patent suit withdrawn before any defence response is a recognisable pattern in assertion-led licensing. Here is what practitioners should take away.
Pre-answer dismissals are a tactical licensing tool, not a defeat
Patent Armory’s withdrawal before the AHA filed any answer preserves maximum flexibility. The ‘without prejudice’ designation means the case can be refiled — often in a different forum or following a failed licensing negotiation. Organisations that receive patent demand letters should treat pre-answer dismissals as a potential pause, not a resolution.
Five patents across call-routing and entity-matching create broad assertion coverage
Spanning three distinct technology clusters — intelligent routing, telephony control, and auction-based matching — this portfolio is structured for wide applicability. Contact-centre vendors, CRM platforms, and organisations with inbound donor or customer call operations should assess whether their implementations overlap with the asserted claims before assuming non-exposure.
Patent v American — key questions answered
It means Patent Armory withdrew its lawsuit under FRCP 41(a)(1)(A)(i) before the AHA filed any answer. ‘Without prejudice’ means the dismissal does not bar Patent Armory from re-filing the same claims in the future. No court ruled on patent validity, infringement, or claim scope, so no estoppel attaches to either party from this proceeding.
Patent Armory asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The patents cover intelligent communication routing systems, telephony control with intelligent call routing, and methods for matching entities in an auction — technologies applicable to enterprise and non-profit contact-centre operations.
The public record does not disclose the reason. A 29-day pre-answer voluntary dismissal is consistent with several scenarios: a private licensing or settlement agreement, a strategic withdrawal to refile in a different forum, or a decision to pause pending further claim analysis. None of these can be confirmed from the public docket alone.
Yes. Because the dismissal was without prejudice and no merits determination was made, Patent Armory retains the right to reassert the same five patents against the AHA in a new action, subject to any applicable statute of limitations and any private agreement that may have been reached off the public record.
All five patents remain in force and were never invalidated. Organisations operating intelligent call-routing, IVR with dynamic queue logic, or auction-based call distribution should consider a freedom-to-operate analysis. Patent Armory’s portfolio spans early-to-mid 2000s through mid-2010s application dates, suggesting potentially broad claim coverage over a wide range of modern telephony architectures.
