Patent Armory v. Dominion Dental Services: Five Call Routing Patents, Dismissed With Prejudice
Patent Armory, Inc. brought an infringement action against Dominion Dental Services, Inc. in the Virginia Eastern District Court, asserting five patents covering intelligent call routing, telephony control, and auction-based entity matching. The parties stipulated to dismiss with prejudice under Rule 41(a)(1)(A)(ii) after just 124 days, with each side bearing its own costs.
Five-patent call routing assertion ends by mutual stipulation
Patent Armory, Inc. filed suit against Dominion Dental Services, Inc. on 18 December 2024 in the Virginia Eastern District Court, asserting infringement of five United States patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The patents collectively cover intelligent communication routing systems, telephony control with intelligent call routing, and methods for matching entities in an auction context — technology areas associated with automated call distribution and routing optimization.
The action closed on 21 April 2025 when both parties filed a stipulated dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Dismissal with prejudice is a final adjudication on the merits as a matter of law, meaning Patent Armory is permanently barred from reasserting these specific infringement claims against Dominion Dental on these patents. Each party agreed to bear its own legal costs, suggesting neither side extracted a fee concession — a common hallmark of a negotiated resolution.
The 124-day duration is notably short for a multi-patent infringement action, suggesting the parties reached an understanding well before any substantive motion practice or claim construction. The public record does not disclose whether a confidential settlement agreement underlies the stipulation, nor the financial terms, if any. The with-prejudice designation is the most commercially significant aspect: it closes the litigation door permanently on these five patents as they relate to Dominion Dental.

Stipulated dismissal with prejudice: what the ruling means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice explained
A stipulated dismissal under FRCP 41(a)(1)(A)(ii) requires the signatures of all parties who have appeared, making it a joint, consensual act. When filed with prejudice, the dismissal operates as a final judgment on the merits — the same claims cannot be brought again in any court. This is the typical vehicle parties use to record a resolution reached outside the public record, without requiring a judge’s order.
Permanent bar on re-litigationPatent Armory cannot refile these claims against Dominion Dental
Dismissal with prejudice is a significant concession by a plaintiff: Patent Armory, Inc. permanently relinquishes the right to sue Dominion Dental Services on all five asserted patents. Whether this reflects a paid settlement, a licensing arrangement, or an acknowledgment of litigation risk is not disclosed. Importantly, Patent Armory retains the ability to assert these patents against other defendants — only Dominion Dental is protected by this specific dismissal.
Claims extinguished vs. this defendantDominion Dental secures permanent protection from these five patents
For Dominion Dental Services, a with-prejudice dismissal is the most durable outcome short of a judicial invalidity ruling. The company faces no further infringement exposure from Patent Armory on US9456086B1, US10491748B1, US7269253B1, US7023979B1, or US10237420B1. The own-costs structure means no attorneys’ fee award was extracted by either side, which is consistent with a commercially negotiated exit rather than a clear litigation win or loss.
Full protection securedCall routing patent assertions: sector risk persists for other companies
This dismissal resolves only the Dominion Dental exposure. Patent Armory’s portfolio — covering intelligent routing, telephony control, and auction-based matching — remains active and assertable against other companies deploying similar communication infrastructure. Healthcare, dental, and insurance companies using automated call routing or IVR systems should note that this case signals active enforcement activity in this patent cluster.

Official order — verbatim text
The stipulation’s language — ‘dismiss this action with prejudice’ coupled with mutual cost-bearing — is a standard formulation that deliberately avoids any admission of liability or infringement. The with-prejudice designation carries significant legal weight: courts treat it as a final judgment on the merits, triggering res judicata. The absence of any carve-out language suggests the resolution is comprehensive as to all asserted patents and accused products listed in the complaint.
US9456086B1 — Intelligent communication routing system and method
US9456086B1 (application no. US12/719827) is the lead asserted patent in this action, directed to intelligent communication routing systems and methods — technology that automates how inbound calls or communications are directed based on dynamic criteria. The portfolio also includes US10491748B1 (entity matching in auction contexts), US7269253B1 and US7023979B1 (telephony control with intelligent routing, earlier-generation filings), and US10237420B1. Application dates span from 2003 to 2017, creating a portfolio with both mature and active-term patents.
For the dental and healthcare insurance sector, intelligent call routing is operationally critical infrastructure: inbound patient and member calls are typically handled by automated distribution and routing systems. The assertion of this portfolio against Dominion Dental Services suggests the patent holder views such commercial telephony deployments as falling within the claims. Any company in managed care, dental benefits, or health insurance that routes high call volumes through intelligent or rules-based systems should evaluate exposure to this five-patent cluster.
Should you run an FTO against US9456086B1 and the Patent Armory portfolio?
If your organisation operates intelligent call routing, IVR, or telephony control infrastructure — particularly in healthcare, dental, or insurance services — this five-patent portfolio warrants a targeted freedom-to-operate assessment. The Dominion Dental case confirms the portfolio is actively asserted against commercial telephony deployments. Given the staggered application dates (2003–2017), some patents may have expired while others carry significant remaining term.

What this case signals for the communication routing IP landscape
A multi-patent assertion resolved in 124 days points to concentrated enforcement risk in call routing and telephony control technologies.
Short duration suggests early-stage settlement or licensing resolution
A five-patent infringement action that closes in 124 days — with no substantive docket activity reaching the public record — is consistent with a pre-answer or early-discovery resolution. Companies receiving demand letters or complaints from Patent Armory in this technology area should expect rapid escalation pressure designed to encourage quick settlement.
Dismissal with prejudice protects Dominion Dental but not its competitors
The with-prejudice bar is defendant-specific. Other companies in dental services, healthcare administration, or any sector using intelligent call routing infrastructure remain exposed to the same five-patent portfolio. The assertion against Dominion Dental establishes a litigation template that could be reused efficiently against similar defendants.
Patent v Dominion — key questions answered
Dismissal with prejudice in this case means Patent Armory, Inc. is permanently barred from reasserting infringement claims against Dominion Dental Services on the five asserted patents. Filed under Rule 41(a)(1)(A)(ii), the stipulation is treated as a final judgment on the merits. Patent Armory retains the right to assert the same patents against other defendants.
Patent Armory asserted five patents: US9456086B1 (intelligent communication routing), US10491748B1 (entity matching in auction systems), US7269253B1 and US7023979B1 (telephony control with intelligent routing), and US10237420B1. The accused products included intelligent communication routing systems and telephony control systems.
The public record shows only a stipulated dismissal with prejudice, with each party bearing its own costs. No settlement agreement, financial terms, or licensing arrangement is disclosed in the docket. The with-prejudice designation and short 124-day duration are consistent with a confidential resolution, but this cannot be confirmed from the public record alone.
The case lasted 124 days, filed on 18 December 2024 and closed on 21 April 2025. This is notably brief for a five-patent infringement action, suggesting the parties reached an agreement early in the litigation — likely before significant motion practice or claim construction proceedings.
No. The dismissal with prejudice is specific to Dominion Dental Services, Inc. Patent Armory retains full enforcement rights against all other parties on US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. Other companies using intelligent call routing or telephony control systems — particularly in healthcare and dental services — remain exposed to potential assertion.
