Patent Armory v. Capriotti’s Sandwich Shop: Dismissed With Prejudice in 80 Days
Patent Armory, Inc. asserted five telephony and intelligent call-routing patents against sandwich chain Capriotti’s in the Eastern District of Texas. The plaintiff voluntarily dismissed all claims with prejudice under FRCP 41(a)(1)(A)(i) just 80 days after filing — extinguishing any future re-filing of the same claims.
A rapid exit: five routing patents, one sandwich chain, zero merits ruling
On April 9, 2024, Patent Armory, Inc. filed suit against Capriotti’s Sandwich Shop, Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 2:24-cv-00236), before Judge Rodney Gilstrap. The complaint alleged infringement of five patents — US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 — covering intelligent communication routing systems, telephony control with intelligent call routing, and auction-based entity matching methods.
On June 28, 2024, Patent Armory filed a notice of voluntary dismissal with prejudice under FRCP 41(a)(1)(A)(i), which requires no court order and takes effect upon filing. Judge Gilstrap accepted and acknowledged the dismissal, closing the case with each party bearing its own costs. The with-prejudice designation is legally significant: Patent Armory is permanently barred from re-asserting the same claims against Capriotti’s in any future action.
The 80-day lifespan is notably short even for cases resolved pre-discovery. The public record does not disclose whether a confidential settlement was reached; the cost-bearing order — each side pays its own fees — is consistent with either a negotiated resolution or a unilateral decision to withdraw. The absence of any disclosed monetary judgment or license term leaves the commercial outcome ambiguous from the public record alone.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit, permanent bar
FRCP 41(a)(1)(A)(i) allows a plaintiff to dismiss without a court order before the defendant serves an answer or a motion for summary judgment. Filing the notice is self-executing — it takes effect immediately. The with-prejudice designation converts what would otherwise be a withdrawal into a final adjudication on the merits for res judicata purposes, permanently foreclosing re-litigation of the same claims against the same defendant.
Voluntary — no merits rulingPatent Armory surrenders all claims permanently against Capriotti’s
By choosing dismissal with prejudice, Patent Armory permanently extinguished its right to assert these five patents against Capriotti’s on the same or substantially similar grounds. This is strategically unusual for a licensing-focused plaintiff unless a commercial resolution was reached or continued litigation was deemed uneconomical. The public record does not disclose any settlement payment or license grant, so the underlying rationale remains uncertain.
Claims permanently extinguishedCapriotti’s walks away with no liability and no cost award
Capriotti’s faced no merits adjudication and incurred no judgment. The court’s each-party-bears-own-costs order means Capriotti’s cannot recover its legal fees despite being a prevailing party in substance. Notably, the dismissal with prejudice does provide Capriotti’s with permanent protection against Patent Armory re-asserting these five patents in future litigation — a meaningful practical benefit even without a formal win on the merits.
No liability — cost recovery deniedEarly dismissal pattern raises licensing strategy questions
The sub-90-day resolution before any substantive motion practice is consistent with a rapid licensing negotiation or a strategic retreat after defendant resistance. For hospitality and restaurant operators using third-party telephony or call-routing platforms, this case suggests continued NPE attention to communication infrastructure IP. The five patents span applications filed between 2003 and 2017, indicating a broad and mature portfolio that may be asserted against other defendants.

Official order — verbatim text
The court’s acceptance of the Rule 41(a)(1)(A)(i) notice is procedural rather than substantive — Judge Gilstrap made no finding of infringement, validity, or claim construction. The with-prejudice designation, however, carries the legal weight of a final judgment for res judicata purposes as between these specific parties. The each-party-bears-own-costs order forecloses any fee-shifting claim by Capriotti’s, meaning the case ended without financial consequence to either side beyond their own litigation spend.
US9456086B1 — Intelligent communication routing system and method
US9456086B1, the lead asserted patent, covers an intelligent communication routing system and method — technology that dynamically directs inbound calls or communications based on configurable logic, caller data, or real-time conditions. The application (US12/719827) reflects development work consistent with the early VoIP and IVR innovation wave. The accompanying patents extend into auction-based entity matching (US10491748B1, US10237420B1) and foundational telephony control systems (US7269253B1, US7023979B1), the latter two with application dates reaching back to the mid-2000s.
The breadth of this five-patent portfolio — spanning routing logic, telephony control, and dynamic entity matching — makes it relevant to any platform handling inbound call distribution, lead routing, or click-to-call functionality. Restaurant chains, retailers, and service businesses relying on cloud-based phone systems or third-party call centres are potential exposure vectors. The patents’ maturity and granted status in the US suggests they have survived initial examination, though none appear to have been tested through IPR or litigation to a final merits ruling.
Should you run an FTO against US9456086B1 and the Patent Armory portfolio?
Any company operating intelligent call routing, IVR systems, VoIP-based call distribution, or auction-based lead routing platforms should treat this five-patent portfolio as a live risk vector. The Eastern District of Texas filing against an end-user (a restaurant chain) rather than a technology provider signals that NPE enforcement is not limited to telecom vendors — it reaches downstream operators. Hospitality groups, franchisors, and multi-location retailers with centralised phone infrastructure are plausible next targets.
PatSnap Eureka’s FTO Search Agent can map each claim of US9456086B1, US10491748B1, US7269253B1, US7023979B1, and US10237420B1 against your product architecture, identify prior art that could support an IPR petition, and flag design-around options. Given that no claim construction has ever been issued in litigation, the claim scope remains formally undefined — making a proactive FTO analysis especially valuable before any licensing demand arrives.

What this case signals for the telephony IP and hospitality sector landscape
An NPE asserting five call-routing patents against a restaurant chain in the Eastern District of Texas is a pattern worth tracking for any business relying on third-party telephony.
Restaurant and hospitality operators face telephony NPE risk
Patent Armory’s targeting of Capriotti’s — a restaurant chain rather than a telecom provider — suggests NPEs are expanding enforcement of communication routing patents into end-user defendants. Any business deploying intelligent IVR, call routing, or VoIP systems sourced from third-party vendors should assess whether their vendor agreements include IP indemnification for exactly this type of assertion.
Eastern District of Texas remains NPE’s preferred forum
Judge Gilstrap’s docket in the Eastern District of Texas continues to attract NPE filings. The rapid 80-day closure here does not diminish the forum’s attractiveness for plaintiffs — it demonstrates that quick resolutions, whether by settlement or retreat, are achievable without protracted litigation costs for either side.
Patent v Capriotti’s — key questions answered
Dismissal with prejudice under FRCP 41(a)(1)(A)(i) means Patent Armory permanently relinquished its right to sue Capriotti’s on these five patents. The dismissal carries res judicata effect — the same claims cannot be re-filed against the same defendant in any future action. No merits ruling on infringement or validity was ever issued.
Patent Armory asserted five US patents: US9456086B1 (intelligent communication routing system and method), US10491748B1, US7269253B1, US7023979B1 (telephony control systems with intelligent call routing), and US10237420B1 (method and system for matching entities). The products at issue included intelligent communication routing systems and telephony control platforms.
The public record does not disclose a settlement. The case was closed via a voluntary Rule 41(a)(1)(A)(i) dismissal with prejudice filed by Patent Armory, with each party bearing its own costs. A confidential settlement is a plausible explanation for this outcome, but cannot be confirmed from publicly available court documents.
The Eastern District of Texas, particularly before Judge Rodney Gilstrap, remains a historically favoured forum for NPE patent filings due to its established patent litigation procedures and plaintiff-friendly perception. Patent Armory, as a non-practising entity, selected this venue consistent with common NPE litigation strategy, though 2024 filing patterns show continued use of this district for assertion campaigns.
Restaurant chains and hospitality operators using third-party intelligent call routing, IVR, or VoIP call distribution systems should assess exposure to Patent Armory’s five-patent portfolio. Because no claim construction has been issued and no merits ruling exists, the enforceable scope of these patents remains undefined. A freedom-to-operate analysis mapping product architecture against patent claims is advisable, particularly for multi-location operators with centralised telephony infrastructure.
