Patent Armory v. Inova Health Care Services: Dismissed With Prejudice After 183 Days
Patent Armory, Inc. asserted five patents covering intelligent call routing and telephony control systems against Inova Health Care Services in the Eastern District of Virginia. The parties filed a joint stipulation under Rule 41(a)(1)(A)(ii) to dismiss the entire action with prejudice — closing the case permanently just six months after filing.
Five call-routing patents, one swift stipulated exit — with prejudice
Patent Armory, Inc. filed suit against Inova Health Care Services in the Eastern District of Virginia on 5 June 2024, asserting infringement of five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. The asserted patents span intelligent communication routing, telephony control with intelligent call routing, and method-and-system claims for matching entities in an auction — technologies with broad applicability to enterprise and healthcare contact-centre environments.
The case closed on 5 December 2024 — exactly 183 days after filing — when the parties filed a joint stipulation to dismiss with prejudice under 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; Patent Armory is permanently barred from bringing these same infringement claims against Inova on any of the five asserted patents. The res judicata effect covers the specific claims made in this action.
The six-month lifecycle is notably short for a five-patent infringement action, suggesting the parties likely reached a private resolution — whether a licence, covenant not to sue, or straightforward walk-away — before substantive motion practice or claim construction. No court-filed financial terms are publicly available. What drove the quick settlement is not disclosed in the public record, but Patent Armory’s pattern of asserting call-routing portfolios and Inova’s retention of Perkins Coie LLP are both consistent with a well-resourced defence response that may have accelerated resolution.

Dismissed with prejudice: what the stipulation means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal — what it means
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), both parties jointly sign a stipulation of dismissal that takes effect immediately upon filing — no court order required. When that stipulation specifies ‘with prejudice,’ the dismissal operates as a final judgment on the merits. The court’s docket closes and no further proceedings are possible on the same claims between these parties.
Permanent, consent-based closurePatent Armory cannot refile — a hard stop on these claims
By agreeing to dismiss with prejudice, Patent Armory permanently waived its right to reassert any of the five patents against Inova on the facts alleged in this complaint. Res judicata attaches. However, the underlying patents remain in force and Patent Armory may continue to assert them against other defendants. The public record does not disclose whether Patent Armory received any financial consideration for agreeing to this outcome.
Claims extinguished vs. Inova onlyInova secures permanent protection from these five patents
The with-prejudice dismissal gives Inova Health Care Services a durable defence: it cannot be sued again by Patent Armory on US9456086B1, US10491748B1, US7269253B1, US7023979B1, or US10237420B1 for the conduct at issue. Whether Inova obtained a broader licence — covering future use or related patent families — is not disclosed. Perkins Coie’s early involvement suggests a defence strategy that may have included validity challenges or design-around analysis.
Permanent bar on these claimsSwift resolution limits exposure but patents remain live for others
For other healthcare or enterprise organisations deploying intelligent call-routing or telephony-control systems, this case is a signal — not a clearance. Patent Armory’s portfolio remains enforceable, and the with-prejudice dismissal does not invalidate any claim. Companies in similar technology spaces should treat this case as evidence of active portfolio enforcement and consider FTO analysis against the five asserted patents before deploying comparable systems.

Official order — verbatim text
The verdict text records a verbatim Rule 41(a)(1)(A)(ii) stipulation — the operative legal language for a consensual, bilateral dismissal with prejudice. The phrase ‘with prejudice’ is the critical qualifier: it converts a procedural exit into a merits-equivalent judgment, triggering res judicata as to Patent Armory’s infringement claims against Inova on all five asserted patents. No liability finding was made, and no court ruling on validity or claim scope was issued. The dismissal is silent on financial terms, which is standard practice when a confidential resolution underlies the stipulation.
US9456086B1 — Intelligent Communication Routing System and Method
US9456086B1 (application no. US12/719827) claims an intelligent communication routing system and method — a technology category that encompasses automatic call distribution, skills-based routing, and dynamic queue management in contact-centre and enterprise telephony environments. The portfolio also includes US10491748B1 and US10237420B1, which cover more recent continuation-era claim sets, alongside foundational patents US7023979B1 and US7269253B1 — the latter two carrying application numbers from the early 2000s, suggesting a long-standing prosecution history with broad claim coverage developed over multiple continuation filings.
Intelligent call-routing patents have become a recurring focus of PAE enforcement activity because the underlying technology is embedded in nearly every enterprise contact-centre platform, healthcare call management system, and cloud telephony service. The breadth of the asserted portfolio — spanning auction-based entity matching, telephony control, and communication routing — means that competitors and healthcare operators using third-party contact-centre software may face indirect infringement exposure. For any organisation deploying intelligent routing infrastructure, this portfolio warrants careful FTO analysis.
Should you run an FTO against US9456086B1 and this call-routing portfolio?
Any enterprise or healthcare organisation operating a contact-centre platform, ACD system, skills-based routing solution, or cloud telephony service should treat Patent Armory’s five-patent portfolio as an active enforcement risk. The breadth of the asserted patents — covering communication routing, telephony control, and auction-based entity matching — means that off-the-shelf UCaaS or CCaaS deployments may fall within claim scope. A demand letter from Patent Armory is a known risk for this technology category.

What this case signals for the intelligent call-routing IP landscape
A rapid with-prejudice exit on a five-patent healthcare tech suit rarely means the underlying portfolio is weak — it often means the opposite.
Fast closures on PAE suits often reflect private licence deals, not merit defeats
A 183-day lifecycle on a five-patent assertion is atypically short. Cases dismissed with prejudice this quickly — before claim construction — typically suggest a confidential settlement or licence was reached. Companies facing similar assertions from Patent Armory should assess whether a licence is commercially preferable to extended litigation.
Inova’s Perkins Coie defence posture likely shaped the outcome timeline
Retaining a firm of Perkins Coie’s calibre signals a defendant prepared to contest validity and claim scope aggressively. The speed of resolution is consistent with a strong early defence response — possibly including IPR filing threats or an inter partes review petition — that accelerated Patent Armory’s decision to settle.
Patent v Inova — key questions answered
Patent Armory, Inc. sued Inova Health Care Services in the Eastern District of Virginia on 5 June 2024 for infringement of five call-routing and telephony patents. The case was dismissed with prejudice by joint stipulation under Rule 41(a)(1)(A)(ii) on 5 December 2024 — 183 days after filing. No court ruling on the merits was issued.
Patent Armory asserted five patents: US9456086B1 (intelligent communication routing system), US10491748B1, US7269253B1 (telephony control with intelligent call routing), US7023979B1, and US10237420B1. The portfolio covers intelligent call routing, telephony control systems, and auction-based entity matching methods.
Dismissal with prejudice under Rule 41(a)(1)(A)(ii) operates as a final judgment on the merits. Patent Armory is permanently barred from reasserting any of the five patents against Inova for the conduct alleged in this complaint. The res judicata effect is binding, though the patents remain enforceable against other defendants.
The public record does not disclose any financial terms. The joint stipulation of dismissal with prejudice is silent on consideration. It is common practice for parties reaching a confidential licence or settlement agreement to file a bare Rule 41 stipulation without disclosing financial terms in the court record.
Yes. The with-prejudice dismissal binds only Patent Armory and Inova. All five patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — remain in force and enforceable. Enterprises and healthcare organisations deploying intelligent call-routing, ACD, or telephony-control systems should conduct freedom-to-operate analysis against this portfolio.
