Patent Armory v. NWN Corporation: Dual-Patent Infringement Action Dismissed in 47 Days
Patent Armory, Inc. filed suit in the Delaware District Court against NWN Corporation, asserting two patents covering auction-based entity matching and intelligent telephony call routing. The case resolved by stipulated dismissal with prejudice in just 47 days — a timeline that suggests early settlement or licensing resolution without prolonged litigation.
Dual-Patent Assertion Against IT Solutions Provider Resolves in Under Two Months
On October 29, 2025, Patent Armory, Inc. filed a patent infringement action in the Delaware District Court (Case No. 1:25-cv-01320) against NWN Corporation, an IT solutions provider. The suit asserted two patents: US9456086B1, covering a method and system for matching entities in an auction, and US7023979B1, covering a telephony control system with intelligent call routing. The case was assigned to Judge Maryellen Noreika.
The parties filed a stipulated dismissal on December 15, 2025 — just 47 days after filing — pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All claims by Patent Armory against NWN Corporation were dismissed with prejudice, meaning Patent Armory cannot re-assert the same claims arising from the same accused conduct. NWN’s counterclaims against Patent Armory were dismissed without prejudice, preserving NWN’s theoretical ability to reassert them. Each party bears its own legal costs.
A 47-day resolution is notably swift even by the standards of quickly-settled patent cases, suggesting the parties reached terms — potentially a license or covenant not to sue — before significant litigation costs accumulated. The asymmetric prejudice structure (plaintiff’s claims with prejudice, defendant’s counterclaims without) is a common hallmark of a negotiated resolution. The public record does not disclose any financial terms or license arrangement.

Stipulated dismissal with prejudice: what the ruling means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal explained
A dismissal under FRCP 41(a)(1)(A)(ii) requires the written consent of all parties and the court’s endorsement. Dismissal ‘with prejudice’ on Patent Armory’s claims is a final adjudication on the merits — Patent Armory is permanently barred from re-filing the same infringement claims against NWN on the same patents for the same accused conduct. The case closed without any judicial ruling on validity or infringement.
Bars re-filing on same claimsPatent Armory exits with prejudice — enforcement window closed against NWN
Patent Armory’s claims being dismissed with prejudice suggests it obtained whatever value it sought — likely a license fee or lump-sum payment — or alternatively concluded the case was not worth pursuing further. The with-prejudice dismissal forecloses future enforcement of US9456086B1 and US7023979B1 specifically against NWN for the accused conduct. Patent Armory retains the patents and can still assert them against other defendants.
Patents remain enforceable vs. othersNWN’s counterclaims survive — but were voluntarily set aside
NWN Corporation’s counterclaims were dismissed without prejudice, meaning NWN technically retains the right to reassert them in future proceedings. In practice, defendants rarely revive counterclaims after a settlement, as the underlying dispute has typically been resolved commercially. NWN avoided a full merits adjudication and avoided any court-imposed cost award — consistent with a negotiated exit rather than a contested win.
Counterclaims preserved in theorySwift resolution limits precedent but signals licensing activity
The 47-day lifecycle produces no claim construction rulings, no validity findings, and no infringement determinations — leaving the patents’ enforceability against third parties entirely intact. IT service providers operating in telephony routing and auction-based matching systems should note that Patent Armory’s patents survived unchallenged. The rapid resolution is consistent with a monetisation strategy targeting licensing fees rather than injunctive relief.

Official order — verbatim text
The stipulated dismissal under Rule 41(a)(1)(A)(ii) is notable for its asymmetry: Patent Armory’s infringement claims are extinguished with prejudice — a permanent bar — while NWN’s counterclaims (likely invalidity or non-infringement declaratory claims) survive on a without-prejudice basis. No court adjudicated the merits. The ‘each party bears own costs’ clause reinforces a clean mutual exit, and the absence of any carve-outs or conditions in the public filing suggests any commercial terms were memorialised in a separate, non-public agreement.
US9456086B1 & US7023979B1 — Auction Matching and Intelligent Call Routing
US9456086B1 (App. No. 12/719827) protects a method and system for matching entities in an auction — technology relevant to dynamic pricing platforms, lead-generation marketplaces, and reverse-auction architectures. US7023979B1 (App. No. 10/385389) covers a telephony control system with intelligent call routing, encompassing logic-driven inbound call management that predates and potentially reads on modern cloud telephony and contact-centre infrastructure. Both patents are granted US patents with B1 designations, indicating first publication after grant.
The combination of an auction-matching patent and a telephony routing patent in a single suit against an IT solutions provider like NWN suggests Patent Armory may be asserting that NWN’s managed services or reseller offerings implicate both technology domains. For the broader IT managed services sector, these patents represent a dual assertion risk: companies bundling cloud communications with marketplace or procurement platforms could face similar claims. The patents’ age and the absence of any IPR challenge in this case leaves their validity formally unchallenged.
Should you run an FTO against US9456086B1 and US7023979B1?
Any company developing or reselling telephony routing systems, UCaaS platforms, contact-centre-as-a-service products, or auction-based matching and lead-distribution platforms should treat these patents as a material FTO concern. Patent Armory demonstrated a willingness to assert in Delaware District Court with a well-resourced filing, and the rapid resolution without a validity ruling means neither patent has been publicly weakened. The risk is particularly acute for IT managed service providers and cloud communications resellers.

What this case signals for the telephony and IT services IP landscape
A 47-day dismissal with prejudice in Delaware suggests strategic licensing pressure, not protracted litigation. Here is what IP teams should take away.
Patent Armory’s patents remain live enforcement tools against other defendants
Because the case closed without any validity or infringement ruling, US9456086B1 and US7023979B1 emerge legally unscathed. Companies operating telephony routing platforms or auction-matching systems remain potential targets. The absence of IPR filings or § 101 challenges in this record means no public prior art attack has yet been mounted against either patent.
The asymmetric prejudice structure is a hallmark of a negotiated deal
When plaintiff’s claims are dismissed with prejudice but defendant’s counterclaims without, it typically reflects a commercial resolution where the defendant paid or received a covenant not to sue. IP counsel advising clients receiving demand letters from Patent Armory should treat this pattern as a data point suggesting the plaintiff has an established licensing playbook and is willing to settle quickly.
Patent v NWN — key questions answered
Patent Armory asserted two patents: US9456086B1, covering a method and system for matching entities in an auction, and US7023979B1, covering a telephony control system with intelligent call routing. Both patents were asserted in the Delaware District Court in an infringement action filed October 29, 2025.
The parties filed a joint stipulation under FRCP 41(a)(1)(A)(ii), agreeing to dismiss Patent Armory’s claims with prejudice and NWN’s counterclaims without prejudice. A with-prejudice dismissal bars Patent Armory from re-filing the same claims against NWN on the same patents for the same accused conduct. The public record does not disclose the commercial terms driving the agreement.
Yes. The dismissal with prejudice applies only to Patent Armory’s claims against NWN Corporation for the specific accused conduct in this case. Patent Armory retains full ownership of both patents and can assert them against other defendants. Neither patent was invalidated or subjected to any IPR or PGR proceeding in this case.
NWN’s counterclaims — likely seeking declarations of non-infringement or invalidity — were dismissed without prejudice, meaning they could theoretically be reasserted in a future proceeding. In practice, once a commercial resolution is reached, defendants rarely revive such counterclaims. The without-prejudice treatment is standard in stipulated dismissals where the defendant did not achieve a full merits victory.
Forty-seven days is exceptionally brief. Patent cases in the Delaware District Court typically take two to four years from filing to trial or resolution. A sub-50-day resolution strongly suggests the parties reached a private commercial agreement — such as a licence or covenant not to sue — very shortly after service of the complaint, without any substantive court proceedings such as claim construction or discovery.
