Patent Armory v. eFinancial: Five Call Routing Patents, Dismissed With Prejudice in 89 Days
Patent Armory, Inc. asserted five patents covering intelligent communication routing, telephony control, and auction-based entity matching against insurance technology firm eFinancial, LLC in the Northern District of Illinois. The parties jointly stipulated to dismiss the action with prejudice under Rule 41(a)(1)(A)(ii), with each side bearing its own costs, closing the case just 89 days after filing.
Five Telephony Patents, One Stipulated Exit: Anatomy of a Fast Resolution
On September 12, 2024, Patent Armory, Inc. filed suit against eFinancial, LLC in the U.S. District Court for the Northern District of Illinois before Judge Martha M. Pacold. The complaint alleged infringement of five U.S. patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing systems, telephony control with intelligent call routing, and auction-based methods for matching entities, technologies directly relevant to eFinancial’s online insurance marketplace and lead-routing operations.
The case closed on December 10, 2024, via a joint stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Both parties agreed to bear their own costs, expenses, and attorneys’ fees. Dismissal with prejudice is a final adjudication on the merits, meaning Patent Armory is permanently barred from bringing the same claims against eFinancial on these five patents. No damages award, injunction, or royalty was publicly disclosed.
The 89-day lifecycle from filing to closure is notably brief for a five-patent infringement action and is consistent with an early negotiated resolution — whether a confidential licensing agreement, a covenant not to sue, or a commercial settlement — reached before substantive motion practice. The public record does not reveal the commercial terms, if any, that accompanied the stipulation. Patent Armory’s use of Rabicoff Law LLC, a firm with a documented history of high-volume patent assertion, and eFinancial’s retention of Perkins Coie LLP suggest the defendant mounted a credible early defence, potentially accelerating resolution.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice explained
A dismissal under Rule 41(a)(1)(A)(ii) requires the signed agreement of all parties and, when filed with prejudice, operates as a final judgment on the merits. The court need not enter a separate order. Patent Armory cannot refile these same infringement claims against eFinancial on any of the five asserted patents — the dismissal functions as a permanent bar under res judicata.
Final — no refiling permittedPatent Armory is permanently barred from reasserting these claims against eFinancial
By agreeing to dismissal with prejudice, Patent Armory relinquished its right to bring these five patents against eFinancial again. Whether this reflects a confidential monetary settlement, a licensing arrangement, or a strategic retreat in the face of a strong invalidity or non-infringement defence is not disclosed in the public record. The patents themselves remain in force and can still be asserted against other defendants.
Claims extinguished vs. eFinancialeFinancial secures permanent peace on all five asserted patents
eFinancial, represented by Perkins Coie LLP, obtained a with-prejudice dismissal, which is the strongest available exit short of an invalidity ruling. The own-costs arrangement means no fee-shifting under 35 U.S.C. § 285, suggesting the case did not reach the threshold of ‘exceptional’ conduct required for such an award. eFinancial’s call-routing and lead-matching platform faces no further exposure from Patent Armory on these specific patents.
Full resolution — no fee awardQuick resolution limits discovery exposure but leaves patent validity intact
The 89-day closure prevented costly claim construction, discovery, and expert proceedings. However, because the patents were not invalidated, they remain available for assertion against other operators of intelligent call-routing and insurance lead-distribution platforms. Competitors of eFinancial in the insurtech and telephony routing space should treat these five patents as live enforcement assets with demonstrated willingness to litigate.

Official order — verbatim text
The stipulation’s language — ‘dismiss this action with prejudice’ with each party bearing its own costs — is precise and consequential. The with-prejudice designation forecloses any future action by Patent Armory against eFinancial on the five asserted patents, functioning as a final judgment on the merits without requiring a court ruling on the substance of the infringement claims. The mutual own-costs provision indicates no finding of exceptional case conduct under 35 U.S.C. § 285, and no public damages figure or royalty rate was established. The patents themselves remain valid and enforceable against third parties.
US9456086B1 and four further patents — intelligent call routing and telephony control
The five asserted patents span two core technical domains: intelligent communication routing (US9456086B1, US10491748B1, US10237420B1) and telephony control systems (US7269253B1, US7023979B1). Application dates range from the early 2000s to the mid-2010s, capturing both foundational telephony routing logic and later refinements incorporating auction-based entity matching — a method by which inbound consumer inquiries are routed to the highest-bidding or best-matched service provider in real time, directly relevant to insurance lead distribution platforms.
For an insurtech operator like eFinancial, which connects consumers with insurance carriers through automated lead-routing infrastructure, all five patents present non-trivial read-across risk. The auction-based matching patent (US10491748B1) in particular covers a mechanism widely deployed in performance marketing and insurance distribution. Patent Armory’s willingness to assert the full portfolio in a single action suggests confidence in the breadth of coverage and signals that other platforms using comparable routing and matching architectures face similar exposure.
Should your platform run an FTO against US9456086B1 and this call-routing family?
Any company operating an intelligent call-routing platform, insurance lead marketplace, or auction-based consumer-to-provider matching system should treat this five-patent family as a priority FTO target. Patent Armory has demonstrated active enforcement willingness, and the patents survive this litigation fully valid. Operators in insurtech, lead generation, contact centre technology, and performance marketing are all plausibly within scope of one or more claims.
PatSnap Eureka’s FTO Search Agent can map each of the five patent numbers against your product architecture, identify claim elements that intersect with your routing and matching logic, surface prior art that could support IPR petitions, and monitor the Patent Armory portfolio for new continuations or assignments. Running this analysis before a demand letter arrives is materially cheaper than defending a filed action.

What this case signals for the insurtech and call-routing IP landscape
A five-patent assertion resolved in under 90 days reveals both the playbook and its limits in intelligent routing IP enforcement.
High-volume patent asserters target call-routing platforms — prepare early
Patent Armory’s use of Rabicoff Law LLC — a firm associated with serial patent assertion campaigns — signals a pattern-based enforcement strategy. Insurtech and telephony routing operators should audit their exposure to this patent family proactively, before a filing compels expensive reactive defence.
Dismissal with prejudice is the gold standard exit — but it costs both parties
eFinancial secured a permanent bar against reassertion by Patent Armory, but the own-costs structure means no § 285 fee recovery. For defendants facing similar claims, early engagement with experienced patent litigation counsel — as eFinancial did with Perkins Coie — consistently produces faster and lower-cost resolution than prolonged motion practice.
Patent v EFINANCIAL — key questions answered
Patent Armory, Inc. sued eFinancial, LLC in the Northern District of Illinois on September 12, 2024, asserting five patents covering intelligent call routing, telephony control, and auction-based entity matching. The parties stipulated to dismiss the action with prejudice under Rule 41(a)(1)(A)(ii) on December 10, 2024, with each side bearing its own costs. The case closed after 89 days without any public judgment on the merits.
Patent Armory asserted US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These patents cover intelligent communication routing systems, telephony control with intelligent call routing, and auction-based methods for matching entities — technologies relevant to eFinancial’s insurance lead-routing and marketplace operations.
Dismissal with prejudice operates as a final judgment on the merits under res judicata. Patent Armory is permanently barred from reasserting infringement claims against eFinancial based on the five patents at issue in this case. The patents themselves remain valid and enforceable against other defendants, but eFinancial has secured permanent protection from further suit by Patent Armory on these specific claims.
The 89-day closure is consistent with early negotiated resolution before substantive motion practice — typically a confidential licensing agreement, covenant not to sue, or commercial settlement. The involvement of Perkins Coie LLP for the defendant and Rabicoff Law LLC for the plaintiff suggests both sides had experienced counsel capable of rapidly assessing the litigation risk and reaching an efficient exit. The public record does not disclose the commercial terms, if any.
Yes. Because the case was dismissed without any invalidity finding, all five asserted patents remain in force. Patent Armory has demonstrated active enforcement willingness against call-routing and insurtech platforms. Other operators using intelligent communication routing, telephony control systems, or auction-based lead matching should assess their exposure to this patent family and consider freedom-to-operate analysis and IPR petition options.
