Patent Armory v. Chuy’s Opco: Five Call Routing Patents, Dismissed in 73 Days
Patent Armory, Inc. filed suit against Chuy’s Opco, Inc. in the Western District of Texas asserting five patents covering intelligent call routing, telephony control, and auction-based entity matching systems. The plaintiff voluntarily dismissed the case with prejudice just 73 days after filing, before the defendant had answered or moved for summary judgment.
Five Telephony Patents, One Tex-Mex Chain, and a Swift Exit
On April 9, 2024, Patent Armory, Inc. filed a patent infringement action against Chuy’s Opco, Inc. — the operating entity behind the Chuy’s Tex-Mex restaurant chain — in the Western District of Texas before Judge Alan D. Albright. The complaint asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1, covering intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity matching methods.
The case closed on June 21, 2024, just 73 days after filing. Patent Armory invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to voluntarily dismiss with prejudice, a procedural right available only before the defendant has served an answer or a motion for summary judgment — both of which were absent here. Dismissal with prejudice permanently extinguishes Patent Armory’s right to bring these specific claims against Chuy’s Opco again.
The 73-day lifespan is notably brief even by the standards of pre-answer dismissals. The public record is silent on whether a private settlement, licensing agreement, or strategic reassessment drove the exit. The choice of ‘with prejudice’ — rather than without — may suggest a negotiated resolution was reached, though no terms are publicly disclosed. What the record does confirm is that Chuy’s Opco never engaged on the merits.

Dismissed with prejudice: what Rule 41(a)(1)(A)(i) means for both parties
Rule 41(a)(1)(A)(i) gives plaintiffs a unilateral exit — but at a cost
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. Here, Patent Armory elected dismissal with prejudice, meaning the dismissal operates as a final adjudication on the merits. The court need not approve the filing; it is self-executing. This is the earliest and cleanest procedural exit available in U.S. federal litigation.
Pre-answer voluntary dismissalWith or without prejudice? The public record is silent on the drivers
Voluntary dismissal can be filed with or without prejudice under Rule 41. Without prejudice would have preserved Patent Armory’s right to refile; with prejudice permanently bars re-assertion of the same claims against Chuy’s Opco. Patent Armory chose with prejudice — an unusual concession absent a settlement. The public docket does not disclose whether a licensing payment or commercial agreement accompanied this filing, leaving the true driver unknown.
Prejudice status: with prejudiceChuy’s Opco exits without ever answering — effectively a full defence win
Chuy’s Opco never filed an answer, never engaged on claim construction, and incurred no merits exposure. The dismissal with prejudice means the five asserted patents cannot be re-asserted against Chuy’s in a new action. Represented by Vorys, Sater, Seymour & Pease LLP, the defendant’s litigation posture — or early settlement leverage — appears to have prompted a rapid resolution without any court-ordered relief against it.
Defendant: no merits findingRapid dismissal with prejudice limits downstream assertion risk for this defendant
For Chuy’s Opco and similarly situated hospitality operators using third-party call routing and telephony platforms, the with-prejudice dismissal removes this specific plaintiff’s threat permanently. However, the five patents remain live and enforceable against other defendants. Companies in the restaurant, hospitality, and contact-centre sectors using intelligent call routing systems should note that Patent Armory’s portfolio remains active and assertable elsewhere.

Official order — verbatim text
The dismissal was filed unilaterally by Patent Armory under Rule 41(a)(1)(A)(i), requiring no judicial approval or defendant consent. The with-prejudice designation is the legally significant element: it converts a procedural exit into a final judgment on the merits, permanently extinguishing Patent Armory’s right to reassert these five patents against Chuy’s Opco. No claim construction, no invalidity analysis, and no damages assessment entered the record. The phrasing confirms the defendant had neither answered nor moved for summary judgment at the time of filing, meaning the full procedural window for unilateral dismissal was still open.
US9456086B1 — Intelligent Communication Routing System and Method
US9456086B1 (App. No. 12/719827) covers an intelligent communication routing system and method — technology that dynamically directs calls or communications based on rules-based or data-driven logic. The portfolio also includes US10491748B1 (auction-based entity matching in telephony), US7269253B1 and US7023979B1 (foundational telephony control with intelligent routing), and US10237420B1 (communication routing and distribution). Together, the five patents span core and derivative claims in the intelligent call routing domain, filed across application dates suggesting a long-running prosecution and continuation strategy.
This portfolio is strategically positioned to cover third-party call routing infrastructure widely used in hospitality, restaurant, and retail sectors — particularly IVR systems, click-to-call products, and AI-driven customer communication platforms. The breadth of claim coverage across multiple patent numbers and application periods raises the assertion surface area, making it relevant to any company that routes inbound customer calls through automated or semi-automated systems rather than direct human operators.
Should you run an FTO against US9456086B1 and the Patent Armory call routing portfolio?
Any company operating intelligent call routing, IVR, click-to-call, or auction-based lead distribution systems in the hospitality, retail, or contact-centre space should treat this five-patent portfolio as a live FTO concern. Patent Armory has demonstrated willingness to file suit in the Western District of Texas — a plaintiff-favoured venue — and the rapid with-prejudice dismissal against Chuy’s Opco does not reduce risk for other potential defendants. The patents span foundational telephony control claims and more recent communication routing methods.
PatSnap Eureka’s FTO Search Agent allows R&D and legal teams to run structured clearance analysis across all five patent numbers simultaneously, map claim scope against your specific call routing architecture, identify prior art and validity challenges, and monitor Patent Armory’s prosecution activity for continuation filings. Given the multi-patent assertion strategy visible in this case, a full portfolio-level FTO is more protective than single-patent analysis.

What this case signals for the telephony patent assertion landscape
A rapid pre-answer exit suggests either early-stage settlement or a deliberate portfolio management decision — both carry implications for call routing IP risk.
Pre-answer dismissals in WDTX often signal private licensing resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant answers, it typically signals either a licensing payment was secured or the assertion economics no longer justified continuation. In patent assertion entity cases before Judge Albright, this pattern is consistent with structured pre-litigation licensing rather than pure litigation defeat.
The five patents remain live — hospitality sector defendants should monitor
US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 are all still in force. Patent Armory is not barred from asserting them against other defendants. Hospitality operators, call centre platforms, and restaurant chains using intelligent routing or IVR systems should conduct FTO reviews against this portfolio.
Patent v Chuy’s — key questions answered
In Patent Armory v. Chuy’s Opco (6:24-cv-00178), the plaintiff filed a voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i) before the defendant had answered. Dismissal with prejudice constitutes a final judgment on the merits, permanently barring Patent Armory from reasserting the same five patents against Chuy’s Opco in any future action.
Patent Armory asserted five U.S. patents: US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1. These patents cover intelligent communication routing systems and methods, telephony control with intelligent call routing, and auction-based entity matching in telephony contexts.
The case was dismissed just 73 days after filing, before Chuy’s Opco filed an answer. The public record does not disclose the specific reason. The choice of with-prejudice dismissal — rather than without prejudice — is consistent with a negotiated resolution such as a licensing agreement, though no settlement terms have been publicly disclosed.
No. The with-prejudice dismissal only bars Patent Armory from reasserting these five patents against Chuy’s Opco specifically. All five patents remain in force and fully enforceable against other defendants. Companies using intelligent call routing, IVR, or telephony systems should assess their exposure to this portfolio independently.
