Patent Armory v. Mercury Systems: Five Call Routing Patents Dismissed With Prejudice in 46 Days
Patent Armory, Inc. filed an infringement action in the Virginia Eastern District Court against Mercury Systems, Inc., asserting five patents spanning intelligent call routing, telephony control, and auction-based entity matching. The parties jointly stipulated to dismiss all claims with prejudice in just 46 days — a resolution pace that suggests a pre-litigation settlement or rapid licensing agreement was reached.
Five-Patent Telephony Suit Ends in Weeks via Stipulated Dismissal
On September 9, 2024, Patent Armory, Inc. filed suit against Mercury Systems, Inc. in the Virginia Eastern District Court (Case No. 3:24-cv-00645) before Judge Roderick C. Young. The complaint alleged infringement of five U.S. patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing, telephony control with smart call routing, and method and system for matching entities in an auction context. Mercury Systems, a defense and aerospace electronics company, was represented by Fish & Richardson LLP.
The case closed on October 25, 2024, just 46 days after filing, via a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The stipulation is asymmetric: all claims brought by Patent Armory against Mercury Systems were dismissed with prejudice, meaning Patent Armory is permanently barred from re-asserting those same claims against Mercury Systems. Mercury Systems’ counterclaims, however, were dismissed without prejudice, preserving its right to refile if circumstances changed.
The 46-day duration is notably brief for a five-patent infringement action and is consistent with an out-of-court resolution — most likely a licensing agreement or lump-sum settlement — reached before substantive litigation costs accumulated. The public record does not disclose any financial terms. The without-prejudice treatment of Mercury’s counterclaims is a standard protective measure but may also reflect unresolved declaratory judgment positioning that neither party wished to foreclose entirely.

46 days to close — well below the typical 18–24 month district court patent lifecycle
Asymmetric Rule 41 dismissal: what the with/without prejudice split means
Rule 41(a)(1)(A)(ii) stipulated dismissal explained
A stipulated dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires the agreement of all parties who have appeared and takes effect without a court order. It is the standard vehicle for ending litigation by mutual consent — typically following settlement. The court made no merits ruling on any of the five asserted patents, meaning validity, enforceability, and claim scope remain untested by this proceeding.
No merits adjudicationClaims dismissed with prejudice: Patent Armory cannot re-sue Mercury
Dismissal with prejudice is a final judgment on the merits as a matter of law. Patent Armory is permanently barred from asserting these five patents against Mercury Systems in any future action arising from the same accused products or conduct. This term is highly favourable to Mercury and is the standard concession a plaintiff makes when receiving settlement value — it signals consideration flowed to Patent Armory in exchange for this permanent bar.
Permanent bar against re-filingMercury’s counterclaims survive — dismissed without prejudice
Mercury Systems’ counterclaims were dismissed without prejudice, meaning they were not resolved on the merits and could theoretically be refiled. In practice, this is a protective placeholder: Mercury retains declaratory judgment optionality — for example, invalidity or non-infringement claims — should Patent Armory later assert these patents against Mercury’s customers or alter its licensing posture. It does not indicate active litigation intent.
Mercury retains future options46-day close strongly suggests a rapid licensing resolution
Cases of this complexity — five patents, a sophisticated defendant represented by Fish & Richardson — rarely terminate in 46 days through litigation attrition. The speed is consistent with Patent Armory presenting a licensing demand pre-suit or shortly after filing, and Mercury electing to settle rather than invest in inter partes review petitions or claim construction proceedings. No financial terms are public. Other companies operating in intelligent call routing or telephony infrastructure should monitor Patent Armory’s broader enforcement campaign.

Official order — verbatim text
The stipulation’s asymmetric structure — plaintiff’s claims dismissed with prejudice, defendant’s counterclaims dismissed without prejudice — is a deliberate allocation of litigation risk. The with-prejudice dismissal functions as a full release of claims under res judicata principles, permanently extinguishing Patent Armory’s right to re-litigate these patents against Mercury. The without-prejudice carve-out for counterclaims is standard in NPE settlements: Mercury preserves standing to challenge patent validity if the patentee later targets Mercury’s supply chain or customers. No court ever assessed claim construction, validity, or infringement — all five patents exit this proceeding with their presumption of validity intact.
US9456086B1 — Intelligent Communication Routing System and Method
US9456086B1, the lead asserted patent, protects an intelligent communication routing system and method — covering the logic by which telephony systems dynamically direct calls based on contextual or rules-based parameters. The portfolio also includes US10491748B1 and US10237420B1, which extend into auction-based entity matching and advanced routing configurations, alongside earlier foundational patents US7269253B1 and US7023979B1 covering telephony control system architecture. The portfolio spans application filings from the early 2000s through the mid-2010s, reflecting layered continuation strategy.
The strategic breadth of this five-patent portfolio is significant: by covering both the routing logic layer and the matching/auction methodology layer, Patent Armory can assert against a wide range of contact-centre vendors, UCaaS providers, and intelligent routing middleware companies. None of the five patents were invalidated or subjected to IPR in this proceeding, meaning their enforceability is undiminished. Competitors and platform vendors in the communications infrastructure sector should treat this portfolio as an active licensing risk and monitor reexamination history and any pending continuation applications.
Should you run an FTO against US9456086B1 and Patent Armory’s call routing portfolio?
Any product team building or deploying intelligent call routing, contact-centre platforms, UCaaS infrastructure, or auction-based communications matching logic should treat this five-patent portfolio as a live FTO priority. Patent Armory’s demonstrated willingness to file and settle quickly means that a demand letter — rather than extended litigation — is the likely first contact. An FTO analysis completed before commercialisation substantially strengthens your negotiating position and may support design-around options.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against all five asserted patents simultaneously, identify the broadest independent claims, surface relevant prior art for invalidity arguments, and flag any continuation applications still in prosecution. Running this analysis now — before a demand letter arrives — is significantly more cost-effective than responding reactively. Eureka also tracks Patent Armory’s full portfolio to alert you to new filings in this technical domain.

Patent Armory’s portfolio spans core telephony infrastructure — assess exposure now
The five asserted patents cover intelligent call routing, telephony control systems, and entity-matching methods that underpin broad categories of communications infrastructure. Any company deploying contact-centre technology, UCaaS platforms, or auction-based routing logic should conduct an FTO review against this portfolio before receiving a demand letter.
Swift resolution suggests an NPE licensing campaign — not a single-target dispute
The 46-day lifecycle and the with-prejudice/without-prejudice asymmetry are hallmarks of a volume licensing model. Patent Armory and counsel Rabicoff Law LLC have filed across multiple defendants in similar proceedings. Tracking parallel filings can help companies anticipate demand timing and negotiate from a position of strength.
Patent v Mercury — key questions answered
Patent Armory, Inc. sued Mercury Systems, Inc. in the Virginia Eastern District Court on September 9, 2024, asserting five patents covering intelligent call routing and telephony control systems. The case closed October 25, 2024 — 46 days later — via a joint stipulated dismissal under Rule 41(a)(1)(A)(ii). Patent Armory’s claims were dismissed with prejudice; Mercury’s counterclaims were dismissed without prejudice. No merits ruling was issued.
In this case, Patent Armory’s infringement claims against Mercury Systems were dismissed with prejudice, permanently barring re-assertion of these patents against Mercury on the same conduct. Mercury’s counterclaims — likely including invalidity and non-infringement positions — were dismissed without prejudice, meaning Mercury retains the right to refile those claims if circumstances warrant. The asymmetry strongly suggests a negotiated settlement with consideration flowing to Patent Armory.
Patent Armory asserted five patents: US9456086B1 (intelligent communication routing system), US10491748B1 (method and system for matching entities in an auction), US7269253B1 (telephony control), US7023979B1 (telephony control system), and US10237420B1 (communication routing). The products at issue included intelligent communication routing systems and telephony control systems with smart call routing.
The 46-day resolution is well below the 18–24 month average for patent infringement cases in U.S. district courts. The speed is consistent with a pre-suit or early-stage licensing demand that Mercury Systems chose to settle before substantive litigation costs — such as IPR petitions, claim construction, or discovery — were incurred. The public record does not disclose financial terms. Fish & Richardson’s involvement suggests Mercury conducted a rapid cost-benefit analysis.
No. A dismissal with prejudice under Rule 41(a)(1)(A)(ii) is a procedural resolution based on party agreement — it carries no adjudication of patent validity, claim scope, or infringement. All five patents retain their statutory presumption of validity under 35 U.S.C. § 282 and remain enforceable against other parties. The patents were never subjected to inter partes review or claim construction in this proceeding.
