Push Data LLC v. Smoothie King Franchises: Mobile App Patent Suit Dropped in 51 Days
Push Data, LLC asserted three patents covering mobile application and web browser interface technology against Smoothie King Franchises, Inc. in the Eastern District of Texas. The case was voluntarily dismissed without prejudice before Smoothie King filed any answer — ending in just 51 days with each party bearing its own costs.
Three-patent mobile app assertion ends before Smoothie King could respond
Push Data, LLC filed suit against Smoothie King Franchises, Inc. on 8 May 2024 in the Eastern District of Texas before Judge Amos L. Mazzant, asserting infringement of three patents — US7292844B2, US7058395B2, and US7212811B2 — in connection with the Smoothie King Mobile App, related web browser interface, and desktop applications. The patents collectively cover mobile application communication and data-push technology, a domain that has generated significant assertion activity across the retail and QSR sectors.
On 28 June 2024, just 51 days after filing, Push Data filed a notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Smoothie King had not yet served an answer to the complaint, no court order was required. The dismissal is self-executing under Rule 41, meaning the case terminated automatically upon filing. Each party was designated to bear its own costs, expenses, and attorneys’ fees — signalling no financial settlement terms were publicly memorialised.
A 51-day lifecycle resolved before any substantive court activity is consistent with several scenarios: an early licensing agreement reached privately, a decision by plaintiff to reassess claim scope or defendant selection, or a pre-answer settlement that the public record does not disclose. The without-prejudice designation is commercially significant — Push Data retains the legal right to reassert these same patents against Smoothie King or redirect the same claims toward other targets. The absence of defendant counsel on record and the pre-answer timing suggests limited adversarial engagement before resolution.

Voluntarily dismissed without prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a unilateral, court-free exit
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order at any time before the defendant serves an answer. Because Smoothie King had not answered, Push Data held an unconditional right to exit. The dismissal is self-executing — it took effect upon filing of the notice, with no judicial approval required. This is the earliest and cleanest procedural exit available in federal litigation.
Pre-answer voluntary dismissalWithout prejudice: the legal distinction that matters most here
A dismissal without prejudice leaves the underlying claims legally intact — the plaintiff is not barred from refiling the same action in the future. This contrasts sharply with a with-prejudice dismissal, which operates as a final adjudication on the merits. The public record here confirms the without-prejudice designation explicitly. Whether Push Data intends to refile, has reached a private licensing arrangement, or is redirecting these patents elsewhere is not disclosed in the public docket.
Claims survive; refiling possibleSmoothie King exits — but without a merits ruling in its favour
Smoothie King Franchises faces no adverse finding and bears no court-ordered costs. However, the without-prejudice exit provides no formal protection against re-assertion of the same patents. No invalidity determination, no non-infringement finding, and no licensing release is on the public record. Companies in this position often pursue proactive FTO analysis or seek a covenant not to sue to close the exposure gap that a without-prejudice dismissal leaves open.
Dismissed, no merits rulingMobile app patent exposure remains live for QSR and retail app operators
Push Data’s assertion of three mobile application patents against a major QSR brand signals active enforcement intent in the consumer app space. Other franchisors, retailers, and app platform operators using push notification, data synchronisation, or browser interface technology should treat this filing as a sector signal. A without-prejudice dismissal against one defendant is frequently followed by reassertion or parallel filings against similarly-situated targets. FTO clearance on these patent families is advisable for any operator in the mobile commerce stack.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) with precision, confirming no answer had been served and that no court order was therefore needed. The explicit without-prejudice designation and the mutual cost-bearing clause are the two legally operative terms. No infringement finding, no invalidity ruling, and no injunctive relief were ever sought at hearing. The phrasing ‘each party shall bear its own costs’ is standard for pre-answer exits and does not preclude a private financial arrangement from existing off-record.
US7292844B2, US7058395B2 & US7212811B2 — mobile application and browser interface technology
The three patents asserted — US7292844B2, US7058395B2, and US7212811B2 — were filed under application numbers 11/603022, 11/262731, and 11/099486 respectively, placing their priority dates in the mid-2000s, a formative period for mobile application architecture. The patents cover technology related to mobile application communication, push data delivery, and web browser interface interactions — foundational mechanisms now embedded in virtually every consumer-facing mobile and web platform.
From a strategic standpoint, patents covering mid-2000s mobile application infrastructure retain assertion relevance because the underlying technical concepts — push notifications, app-to-server data synchronisation, and browser-app interaction — remain in continuous use across modern QSR apps, retail platforms, and loyalty programme interfaces. Push Data’s decision to assert all three patents simultaneously against the Smoothie King Mobile App and web interface suggests a broad claim-mapping strategy designed to maximise licensing leverage across a defendant’s full digital product stack.
Should your mobile app or QSR platform run an FTO against these three patents?
Any company operating a branded consumer mobile application, push notification infrastructure, or web-based ordering interface should treat this filing as a direct signal. Push Data’s assertion targets functionality — push data delivery, app-browser interaction — that is standard across QSR, retail, and hospitality mobile platforms. If your product team ships features that involve server-to-app data pushing, in-app browser sessions, or loyalty notification systems, these patent families warrant a formal FTO review before a demand letter compresses your timeline.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map your mobile app’s feature set against the claim scope of US7292844B2, US7058395B2, and US7212811B2 in a structured, auditable workflow.

What this case signals for the mobile app and QSR IP landscape
A fast, pre-answer exit on three mobile patents in Texas EDTX carries enforcement and clearance implications that extend well beyond Smoothie King.
Pre-answer dismissals in EDTX frequently signal private licensing resolution
A 51-day lifecycle ending before any answer or court activity is strongly consistent with a private licensing discussion that resolved quickly. Push Data retains its patent portfolio intact and the without-prejudice designation preserves full reassertion rights. IP teams at companies operating consumer-facing mobile apps — particularly in food, beverage, and retail — should monitor these three patent families for subsequent filings.
Three-patent mobile app assertion raises the FTO bar for QSR operators
US7292844B2, US7058395B2, and US7212811B2 collectively cover mobile application communication and browser interface functionality used broadly across QSR and retail app ecosystems. Any franchise or retail brand operating a branded mobile app, push notification system, or web-based ordering interface should assess whether their technology stack intersects with these claim scopes before a demand letter arrives.
Push v Smoothie — key questions answered
Push Data, LLC filed a patent infringement suit against Smoothie King Franchises, Inc. on 8 May 2024 in the Eastern District of Texas, asserting three patents covering mobile application and web browser interface technology. The case was voluntarily dismissed without prejudice on 28 June 2024 — 51 days after filing — before Smoothie King served any answer. Each party bore its own costs.
Push Data asserted US7292844B2, US7058395B2, and US7212811B2 — three patents covering mobile application communication, push data delivery, and web browser interface technology. The asserted products included the Smoothie King Mobile App, its web browser interface, and desktop applications.
A without-prejudice dismissal means no merits ruling was made and the plaintiff retains the right to refile the same claims in future. Smoothie King faces no adverse finding and no cost order, but also receives no formal legal protection — such as a covenant not to sue or invalidity ruling — against future assertion of the same three patents.
The public record does not disclose the reason. A 51-day pre-answer dismissal is consistent with several scenarios: a private licensing agreement reached early, a strategic decision to redirect the assertion, or a reassessment of claim mapping against the specific products. The without-prejudice designation and mutual cost-bearing clause are the only publicly available terms.
The case was filed in the United States District Court for the Eastern District of Texas (case no. 4:24-cv-00405) and assigned to Judge Amos L. Mazzant. EDTX is a historically plaintiff-friendly venue for patent assertion and remains a commonly selected forum for mobile application patent cases.
