Secure Matrix LLC v. Twin Peaks Restaurants: Auth Patent Dismissed With Prejudice
Secure Matrix LLC filed a patent infringement action in the Eastern District of Texas against Twin Peaks Restaurants, LP, asserting US8677116B1 covering systems and methods for authentication and verification. The plaintiff voluntarily dismissed the case with prejudice after 226 days, surrendering all future infringement claims on this patent against this defendant.
Authentication patent suit ends before discovery: a closer look
On January 6, 2025, Secure Matrix LLC filed a patent infringement complaint in the U.S. District Court for the Eastern District of Texas against Twin Peaks Restaurants, LP. The asserted patent, US8677116B1, covers systems and methods for authentication and verification — a broadly applicable technology domain relevant to digital access, identity management, and secure login systems. Secure Matrix was represented by Rabicoff Law LLC, a firm with an established pattern of asserting patents in the Eastern District.
The case closed on August 20, 2025, when Secure Matrix filed a Notice of Voluntary Dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted and acknowledged the notice, formally closing the case. A dismissal with prejudice is a final disposition on the merits — Secure Matrix cannot refile these specific infringement claims against Twin Peaks Restaurants based on US8677116B1. Crucially, each party was ordered to bear its own costs, attorneys’ fees, and expenses.
At 226 days, the resolution is relatively swift for the Eastern District of Texas, suggesting the parties likely reached an agreement — or Secure Matrix concluded litigation was not commercially viable — well before any substantive court proceedings. The public record does not disclose whether a settlement or licensing arrangement was reached, or whether the dismissal reflects an acknowledgment of deficiencies in the infringement position. The absence of docketed defendant agents and law firms suggests Twin Peaks may have engaged early without formal docketing, consistent with pre-answer resolution patterns.

Dismissed with prejudice: what the Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i) dismissal with prejudice explained
A voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i) is filed by the plaintiff before the defendant serves an answer or motion for summary judgment. Unlike a dismissal without prejudice, this filing permanently bars Secure Matrix from reasserting the same patent claims against Twin Peaks based on US8677116B1. The court treats it as a final adjudication on the merits, even though no substantive ruling was ever issued.
Permanent claim barSecure Matrix forfeits all future claims against Twin Peaks
By choosing dismissal with prejudice, Secure Matrix surrenders its right to refile these infringement claims against Twin Peaks on US8677116B1 in any court. This is an unusually final concession for a plaintiff in a voluntary dismissal. It may signal that a licensing resolution was reached — making continued litigation unnecessary — or that Secure Matrix assessed the infringement position as untenable once Twin Peaks signalled its defence posture.
No refile rightsTwin Peaks secures permanent immunity on these claims
Twin Peaks Restaurants, LP emerges with a permanent bar against re-litigation on US8677116B1 by Secure Matrix. Notably, no defendant counsel appears on the docket, which is consistent with a pre-answer resolution. The cost-sharing order — each party bears its own fees — means Twin Peaks did not receive a fee award despite the dismissal, suggesting the resolution was not characterised as exceptional under 35 U.S.C. § 285.
Permanent protection securedUS8677116B1 remains enforceable against other defendants
The with-prejudice dismissal binds only these two parties. US8677116B1 remains a live, enforceable patent that Secure Matrix may assert against other companies operating authentication and verification systems. Businesses in hospitality, retail, and any sector using digital identity or login technology should note this patent remains active and that Rabicoff Law LLC continues to represent assertion interests in the Eastern District of Texas.

Official order — verbatim text
The court’s order accepts and acknowledges Secure Matrix’s Rule 41(a)(1)(A)(i) notice as filed, converting the voluntary dismissal into a formal judicial disposition. The explicit ‘WITH PREJUDICE’ language — capitalised in the original notice — places this beyond a standard tactical withdrawal. The mootness denial of all pending relief requests confirms no substantive issues were adjudicated. The symmetric cost order removes any implication of wrongful conduct by either party, leaving the public record silent on the underlying commercial terms.
US8677116B1 — Systems and methods for authentication and verification
US8677116B1 is a granted U.S. patent covering systems and methods for authentication and verification, filed under application number US13/963941. Authentication and verification patents in this era typically address credential management, identity confirmation, and access control workflows — technology foundational to both consumer-facing digital platforms and enterprise security infrastructure. The patent’s B1 designation indicates it issued without any post-grant reexamination certificate, suggesting the claims have not been publicly challenged through USPTO proceedings.
From a strategic standpoint, authentication and verification patents carry unusually broad assertion potential because the underlying technology is embedded in virtually every digital product category — from restaurant loyalty apps and POS systems to SaaS platforms and mobile commerce. The assertion against a restaurant chain suggests the plaintiff’s theory may target customer-facing authentication flows rather than core security infrastructure. Companies operating digital customer engagement systems, loyalty programmes, or online ordering platforms should treat this patent as an active enforcement risk, particularly given its deployment in E.D. Texas by a specialist assertion firm.
Should your team run an FTO against US8677116B1?
Any company deploying digital authentication systems — including login portals, two-factor authentication workflows, identity verification layers, or access control mechanisms — should assess exposure under US8677116B1. The patent’s assertion against a restaurant chain signals that the claim theory may extend to customer-facing digital touchpoints such as app login, online reservations, or loyalty account verification. Hospitality, retail, and food-service technology teams are especially relevant audiences.

What this case signals for the authentication patent IP landscape
Early dismissals with prejudice in E.D. Texas often mask licensing activity. Here is what practitioners and product teams need to know.
Pre-answer dismissals in E.D. Texas frequently indicate licensing resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant even appears on the docket, it is a strong signal that a licensing agreement or covenant not to sue was reached privately. Secure Matrix’s pattern — asserting broadly applicable tech patents via Rabicoff Law LLC — is consistent with a licensing-driven enforcement strategy rather than litigation to judgment.
Authentication and verification patents carry sector-wide risk beyond hospitality
US8677116B1 covers systems and methods for authentication and verification — a technology claim broad enough to implicate digital login, two-factor authentication, and access control systems across retail, hospitality, SaaS, and fintech. Companies deploying third-party authentication stacks should assess whether their implementations fall within the claim scope of this patent.
Secure v Twin — key questions answered
The case was voluntarily dismissed with prejudice by plaintiff Secure Matrix LLC under Rule 41(a)(1)(A)(i) before Twin Peaks filed an answer. A dismissal with prejudice permanently bars Secure Matrix from refiling the same infringement claims against Twin Peaks based on US8677116B1. The court accepted the notice and closed the case, with each party bearing its own costs.
Yes. The with-prejudice dismissal binds only Secure Matrix and Twin Peaks Restaurants, LP. US8677116B1 remains a valid, enforceable patent and Secure Matrix retains the right to assert it against other defendants. Companies operating authentication or verification systems should not treat this dismissal as a signal that the patent is invalid or withdrawn from enforcement.
The Eastern District of Texas is a historically plaintiff-friendly venue for patent assertion cases and remains a preferred forum for patent assertion entities. Rabicoff Law LLC, which represented Secure Matrix, has an established filing presence in E.D. Texas. The district’s procedural rules and judicial familiarity with patent cases make it attractive for licensing-driven enforcement strategies.
The court ordered each party to bear its own costs, attorneys’ fees, and expenses. This means no fee-shifting under 35 U.S.C. § 285, which requires an ‘exceptional case’ finding based on objective unreasonableness or bad faith. The symmetric cost order is consistent with a negotiated resolution and does not suggest the court found either party’s conduct sanctionable.
US8677116B1 covers systems and methods for authentication and verification. This encompasses digital identity confirmation, credential management, and access control workflows. Companies across hospitality, retail, SaaS, fintech, and any sector using customer-facing login, two-factor authentication, or identity verification systems may fall within the patent’s potential claim scope and should consider conducting a freedom-to-operate analysis.
