Torus Ventures v. Gringo’s Mexican Kitchen: Dismissed With Prejudice After 233 Days
Torus Ventures LLC asserted US7203844B1 — a recursive security protocol for digital copyright control — against Gringo’s Mexican Kitchen in the Eastern District of Texas. After 233 days, the parties filed a joint stipulation of dismissal with prejudice, indicating a private resolution was reached before trial.
A Digital Copyright Patent Assertion Ends Quietly in East Texas
Torus Ventures LLC filed suit against Gringo’s Mexican Kitchen No. 1 Inc. on 2 December 2024 in the Eastern District of Texas before Judge Rodney Gilstrap, asserting infringement of US7203844B1 — a patent covering a method and system for a recursive security protocol for digital copyright control. The case was designated as a member case within a consolidated docket, suggesting Torus Ventures was pursuing a broader assertion campaign involving the same patent.
The case closed on 23 July 2025 via a joint stipulation of dismissal with prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The parties represented that they had ‘reached a resolution’ of the matter, and the court accepted the stipulation, directed closure, and ordered each side to bear its own costs, expenses, and attorneys’ fees. A dismissal with prejudice bars Torus Ventures from re-asserting the same claims against Gringo’s Mexican Kitchen on the same patent in the future.
The 233-day duration and the ‘reached a resolution’ language in the stipulation are consistent with a negotiated private settlement, though the specific financial terms — if any — remain undisclosed. The own-costs order is standard for negotiated exits and does not signal a litigation win or loss. What remains unknown is whether Gringo’s Mexican Kitchen obtained a licence to US7203844B1 or whether Torus Ventures simply withdrew its claims, and whether parallel assertions against other defendants in the consolidated docket are ongoing.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice explained
A joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) requires both parties’ signatures and takes effect upon filing — no judicial merits ruling is issued. ‘With prejudice’ means the dismissed claims are extinguished permanently; Torus Ventures cannot re-file the same patent claims against Gringo’s Mexican Kitchen. This mechanism is the most common vehicle for wrapping up a privately settled patent dispute without a court-determined winner.
No merits adjudicationTorus Ventures closes this defendant — but on what terms?
The ‘reached a resolution’ language in the stipulation is consistent with a negotiated exit — most commonly a licence payment or lump-sum settlement — but the public record is silent on financial terms. By agreeing to dismissal with prejudice, Torus Ventures surrenders its ability to re-assert US7203844B1 against this specific defendant, suggesting it received sufficient value to close the case. Whether parallel assertions against other defendants in the consolidated docket continue is not disclosed here.
Resolution terms undisclosedGringo’s Mexican Kitchen exits — permanently shielded from this claim
The dismissal with prejudice provides Gringo’s Mexican Kitchen with a permanent bar against future assertion of the same claims under US7203844B1 by Torus Ventures. The own-costs order means no fee-shifting occurred, which is standard in settled matters. Whether the defendant obtained a formal licence or simply secured a covenant not to sue is not evident from the public filing, though either outcome eliminates the infringement exposure that prompted the suit.
Permanently protected from re-suitDigital copyright security patents remain a live assertion risk for non-tech defendants
This case is consistent with a pattern of patent assertion entities targeting service-sector businesses — including restaurants — over digital infrastructure such as online ordering, loyalty programmes, or content delivery systems that may implicate security protocol patents. US7203844B1 covers a recursive digital copyright control method, and its application to a restaurant chain suggests broad claim construction arguments. Businesses in similar verticals should audit vendor-supplied digital platforms for exposure to comparable IP.

Official order — verbatim text
The stipulation’s phrasing — that the parties ‘have reached a resolution’ — is legally significant: it signals a private agreement underpinning the dismissal rather than a unilateral withdrawal. The with-prejudice designation, accepted and acknowledged by Judge Gilstrap, permanently extinguishes Torus Ventures’ right to re-assert these specific claims against this defendant. No merits findings, claim constructions, or validity rulings were issued, leaving US7203844B1’s enforceability entirely intact against third parties.
US7203844B1 — Recursive Security Protocol for Digital Copyright Control
US7203844B1, filed under application number US10/465274, covers a method and system implementing a recursive security protocol for digital copyright control. The patent sits within the digital rights management and content-protection domain — technology that governs how digital assets are authenticated, accessed, and protected from unauthorised reproduction. The recursive architecture suggests a layered or nested security model, potentially applicable to any system that enforces access rights over digital content.
The strategic significance of this patent lies in its claim breadth: a recursive protocol framing can potentially read on a wide variety of digital access-control implementations, from streaming and licensing platforms to enterprise content management and point-of-sale digital systems. For service-sector companies deploying third-party digital infrastructure, the patent represents a non-obvious but commercially real risk. Competitor analysis should focus on DRM middleware and digital licence management vendors whose products may independently be the actual locus of infringement.
Should you run an FTO against US7203844B1?
Any organisation deploying digital systems that incorporate access-control, content protection, or licensing enforcement mechanisms — including operators using third-party point-of-sale, online ordering, or digital content platforms — should consider whether US7203844B1’s claims are relevant to their technology stack. The Torus Ventures assertion campaign suggests broad claim construction arguments are being advanced; an FTO analysis before receiving a demand letter is substantially cheaper than defending post-suit.

What this case signals for the digital copyright security IP landscape
A fast, quiet resolution in E.D. Texas suggests Torus Ventures is running a licensing campaign — and non-tech defendants are squarely in scope.
Member case designation signals a multi-defendant assertion campaign
The court’s reference to ‘Member Case No. 2:24-cv-992-JRG’ indicates US7203844B1 is being asserted in a consolidated docket against multiple defendants. Any business operating digital platforms with copyright-protection or access-control features should monitor the lead case and co-defendant filings for claim scope signals.
Restaurants and service businesses are non-obvious targets for digital security patents
Torus Ventures’ decision to name a restaurant chain as a defendant suggests the asserted claims may read on widely deployed third-party digital platforms — point-of-sale systems, online ordering, or digital menus — rather than proprietary technology. Defendants in this position are often better served by targeting the upstream software vendor for indemnification than by litigating alone.
Torus v GRINGO’S — key questions answered
The case was dismissed with prejudice on 23 July 2025 via a joint stipulation filed under Rule 41(a)(1)(A)(ii). The parties represented that they had reached a private resolution. Each party was ordered to bear its own costs, expenses, and attorneys’ fees. No merits ruling on US7203844B1 was issued.
Torus Ventures asserted US7203844B1, which covers a method and system for a recursive security protocol for digital copyright control. The patent was filed under application number US10/465274. The specific product or digital platform implementation alleged to infringe was not detailed in the publicly available dismissal order.
A dismissal with prejudice permanently bars the plaintiff — here, Torus Ventures — from re-asserting the same patent claims against the same defendant, Gringo’s Mexican Kitchen. The claims are extinguished as between these parties. However, the patent US7203844B1 itself remains valid and enforceable against third parties not party to this dismissal.
The joint stipulation states the parties ‘have reached a resolution,’ language that is consistent with a negotiated settlement. However, no financial terms, licence terms, or other conditions are disclosed in the public court record. The own-costs order does not indicate fee-shifting and is standard for mutually agreed exits.
The court’s reference to ‘Member Case No. 2:24-cv-992-JRG’ indicates this was one case in a consolidated docket, suggesting Torus Ventures was asserting US7203844B1 against multiple defendants simultaneously. The status of parallel member cases is not disclosed in this filing. Monitoring the lead consolidated case in E.D. Texas would provide visibility into ongoing assertions.
