Patent Armory v. Help at Home: Five Call Routing Patents, Dismissed With Prejudice
Patent Armory, Inc. asserted five patents spanning intelligent call routing, telephony control, and auction-based entity matching against home-care services provider Help at Home, LLC in the Northern District of Illinois. The case closed in 178 days when the plaintiff filed a voluntary dismissal with prejudice before the defendant had answered, with each party bearing its own costs.
Five-patent call routing case ends before defendant files an answer
On 6 September 2024, Patent Armory, Inc. filed suit against Help at Home, LLC in the U.S. District Court for the Northern District of Illinois (Case No. 1:24-cv-08171), before Judge John J. Tharp. The complaint asserted five U.S. patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing, telephony control with intelligent call routing, and auction-based entity-matching systems, technologies relevant to contact-centre and care-coordination operations.
On 3 March 2025, Patent Armory invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to file a unilateral notice of dismissal with prejudice. Because Help at Home had not yet filed an answer or moved for summary judgment, no court order was required to effect the dismissal. The with-prejudice designation means Patent Armory is permanently barred from reasserting the same claims against Help at Home on these five patents. Each party was ordered to bear its own litigation costs and attorneys’ fees.
The 178-day lifespan and pre-answer exit are consistent with a negotiated resolution — or a plaintiff reassessing claim strength — though the public record is silent on whether any commercial agreement accompanied the dismissal. The fact that Patent Armory’s counsel (Rabicoff Law LLC) filed unilaterally under Rule 41(a)(1)(A)(i) before any responsive pleading suggests the decision was plaintiff-driven. Whether licence terms, a covenant not to sue, or simply a strategic recalibration underpins the exit remains unknown from the public docket.

Dismissed with prejudice: what Rule 41(a)(1)(A)(i) means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit, but with prejudice
Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. Filing with prejudice is an unusual election under this rule — the default would be without prejudice — and it operates as a final adjudication on the merits, permanently extinguishing Patent Armory’s ability to re-sue Help at Home on these five patents.
Permanent bar on re-filingWith prejudice chosen — but the docket is silent on why
A dismissal with prejudice forecloses all future claims on the same patents against the same defendant, while a dismissal without prejudice would preserve the plaintiff’s right to refile. Patent Armory affirmatively chose the with-prejudice designation here. The public record does not reveal whether this reflects a settled agreement, a covenant not to sue, or a unilateral strategic decision — but the commercial significance of the distinction is material to both parties.
Cannot refile against Help at HomeHelp at Home exits without conceding liability or paying disclosed damages
Help at Home never filed an answer, meaning no invalidity defences or non-infringement positions entered the public record. The with-prejudice dismissal nonetheless gives Help at Home permanent protection from these specific five patent claims brought by Patent Armory. Each party bearing its own costs means Help at Home absorbed its own defence spend without recovery — consistent with an early-stage resolution before substantive litigation costs escalated.
Protected from these five patentsPre-answer exit suggests demand-letter economics may have driven the filing
Cases filed by patent assertion entities that terminate before an answer is filed — particularly with no disclosed settlement or damages — are often consistent with licensing-focused strategies where litigation is one lever among several. The five patents asserted span a broad call-routing and entity-matching landscape, suggesting Portfolio value may extend beyond this defendant. Companies operating communication-routing or care-coordination platforms in adjacent sectors should assess exposure to these patents.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) explicitly and appends the with-prejudice election — an important distinction from the rule’s default. The phrase ‘each party shall bear its own costs, expenses, and attorneys’ fees’ signals a clean exit with no fee-shifting, which typically indicates neither party sought an ‘exceptional case’ finding under 35 U.S.C. § 285. The pre-answer timing means the dismissal required no judicial order and carries no merits ruling, leaving the five patents’ validity and enforceability entirely intact against other potential defendants.
US9456086B1, US10491748B1, US7269253B1, US7023979B1 & US10237420B1 — intelligent call routing and entity-matching systems
The five asserted patents collectively cover intelligent routing of communications — including telephony and digital channels — as well as auction-based mechanisms for matching service requesters with service providers. Application dates span from the mid-2000s (US10/385389, US11/387305) through the mid-2010s (US12/719827, US15/797070, US15/856729), indicating a layered portfolio strategy where earlier foundational patents are supplemented by continuation or continuation-in-part filings capturing evolved claim scope across successive technology generations.
For the home-care and telecom sectors, this portfolio is strategically significant: care-coordination platforms routinely rely on intelligent call routing to match clients with caregivers and on automated telephony control to manage inbound and outbound communications at scale. The breadth of claim coverage across five patents — spanning routing logic, auction-based matching, and telephony control — means that a single product implementation could potentially implicate multiple assertions simultaneously, increasing settlement pressure on defendants that rely heavily on communication-routing infrastructure.
Should you run an FTO against US9456086B1 and the Patent Armory portfolio?
Any company developing or operating intelligent call routing platforms, care-coordination communication systems, telephony control software, or auction-based service-matching applications should treat this portfolio as a live enforcement risk. Patent Armory has demonstrated willingness to file in the Northern District of Illinois and to assert all five patents simultaneously. The pre-answer dismissal here does not reduce the portfolio’s enforceability against other defendants — it may actually signal a refined targeting strategy.

What this case signals for the call routing and care-coordination IP landscape
A five-patent assertion ending before an answer is filed raises important questions for any company operating telephony or routing technology.
Pre-answer dismissal with prejudice limits public invalidity record
Because Help at Home never answered, no invalidity arguments, claim charts, or non-infringement positions entered the public record. The five asserted patents therefore remain unchallenged on the merits. Companies in call-routing or care-coordination sectors cannot rely on this case to weaken Patent Armory’s portfolio.
Rule 41 with-prejudice elections by PAEs are commercially significant
When a plaintiff asserting patents voluntarily dismisses with prejudice before the defendant answers, it typically signals either a confidential licence, a covenant not to sue, or a strategic pivot. The absence of a fee-shifting order suggests neither party sought to characterise the other’s conduct as exceptional under 35 U.S.C. § 285.
Patent v Help — key questions answered
Patent Armory, Inc. filed a patent infringement suit against Help at Home, LLC in the Northern District of Illinois on 6 September 2024, asserting five patents covering intelligent call routing and entity-matching systems. On 3 March 2025, Patent Armory voluntarily dismissed the case with prejudice under Rule 41(a)(1)(A)(i) before Help at Home filed an answer. Each party bore its own costs and attorneys’ fees.
Patent Armory asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These patents cover intelligent communication routing systems, telephony control with intelligent call routing, and methods and systems for matching entities in an auction, spanning application dates from the mid-2000s to the mid-2010s.
A voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i) allows a plaintiff to terminate an action without a court order when the defendant has not yet answered or moved for summary judgment. The with-prejudice designation means the dismissal operates as a final adjudication — Patent Armory is permanently barred from bringing the same patent claims against Help at Home. The five patents remain enforceable against other parties.
No merits ruling was issued, so Help at Home did not receive a judicial determination of non-infringement or invalidity. However, the with-prejudice dismissal gives Help at Home permanent protection against Patent Armory reasserting these five patents. The public record does not disclose whether any licensing agreement or commercial terms accompanied the dismissal.
Yes. The voluntary dismissal with prejudice is specific to Patent Armory’s claims against Help at Home. US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 remain fully enforceable against any other party. No invalidity finding or claim limitation was entered in this case, leaving the patents’ scope intact for future enforcement actions.
