S3G Technology v. Smoothie King: Mobile App Patent Suit Ends in 76 Days
S3G Technology, LLC asserted four mobile application patents against Smoothie King Franchises’ Android and iOS apps in the Eastern District of Texas. The parties jointly moved to dismiss with prejudice after just 76 days, with each side bearing its own costs — a resolution timeline consistent with a negotiated settlement.
Four Mobile App Patents, One Quick Exit: Anatomy of a Fast Settlement
On May 22, 2025, S3G Technology, LLC filed suit against Smoothie King Franchises, Inc. in the Eastern District of Texas (Case No. 2:25-cv-00581), asserting infringement of four U.S. patents — US9940124B2, US11662995B2, US9304758B2, and US10387140B2 — directed at mobile application technology for Android and iOS platforms. The accused products were Smoothie King’s customer-facing mobile applications and the underlying systems, servers, and software supporting them.
The case closed on August 6, 2025, when the court granted a joint motion to dismiss filed by both parties. The dismissal was entered with prejudice, meaning S3G Technology is permanently barred from re-asserting the same patent claims against Smoothie King in a future action. Notably, the order directed each party to bear its own costs, attorneys’ fees, and expenses — a term that typically reflects a negotiated resolution rather than a unilateral capitulation by either side.
The 76-day resolution is notably rapid for a multi-patent infringement case in E.D. Texas, suggesting that substantive negotiations were likely underway before or shortly after filing. The public record does not disclose the financial terms, if any, of the resolution. The court’s order also noted the lead case remains open, indicating this was a member case within a broader consolidated docket — suggesting S3G may be pursuing parallel actions against other defendants under the same patent portfolio.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice bars any future re-filing on these claims
A dismissal with prejudice under Federal Rule of Civil Procedure 41 operates as a final adjudication on the merits. S3G Technology cannot bring the same patent claims — across all four asserted patents — against Smoothie King in any future proceeding. The joint nature of the motion means both parties consented, distinguishing this from a court-imposed sanction or a defendant win on the merits.
Rule 41 — final, no re-filingS3G permanently releases Smoothie King — but patents remain enforceable elsewhere
By agreeing to dismissal with prejudice, S3G Technology has permanently released its claims against Smoothie King. However, the four asserted patents are not invalidated by this outcome — they remain active and enforceable against other parties. The own-costs term and the continued openness of the lead case suggest S3G may have extracted consideration or pivoted strategy rather than simply surrendering its position.
Patents survive — claims releasedSmoothie King achieves permanent peace on these four patents
Smoothie King Franchises secures a with-prejudice dismissal, giving it permanent protection from S3G Technology re-asserting these four mobile app patents. No finding of infringement was made, and no damages were publicly awarded. The own-costs structure means Smoothie King absorbs its own legal fees — typical where both sides prefer speed and certainty over protracted litigation to establish a fee-shifting record.
Permanent release securedMobile app IP assertions in QSR remain a live risk for the sector
The rapid resolution and the retention of an open lead case signal that S3G Technology operates a patent assertion model targeting mobile app platforms across multiple defendants. Quick-service restaurant and retail brands running loyalty or ordering apps on Android and iOS should treat this case as a sector-wide signal. Companies deploying similar app architectures face non-trivial risk from assertion of these four patents unless they conduct proactive FTO analysis.

Official order — verbatim text
The court’s order grants a joint motion to dismiss with prejudice, reflecting mutual consent rather than a merits adjudication. The ‘with prejudice’ designation is legally significant: it extinguishes S3G Technology’s right to re-assert these four patents against Smoothie King permanently. The own-costs provision and the denial of all pending relief as moot confirm no substantive rulings on infringement or validity were made. The instruction to maintain the lead case open is a procedural marker indicating this member case was one of potentially multiple parallel actions.
US9940124B2 — Mobile App Execution and Platform Technology Patents
The four asserted patents — US9940124B2, US11662995B2, US9304758B2, and US10387140B2 — share a common technical domain: the execution, operation, and delivery of mobile applications across Android and iOS environments, encompassing systems, methods, computing devices, servers, software, and non-transitory computer-readable storage media. The application dates span from approximately 2015 to 2021, suggesting a deliberate continuation or continuation-in-part prosecution strategy designed to extend protection as mobile app architectures evolved.
For the quick-service restaurant and retail sectors, this portfolio is strategically significant because modern customer engagement — ordering, loyalty, promotions — is almost entirely mediated by mobile apps. Any brand operating a consumer-facing app on Android or iOS that involves server-side processing, software execution methods, or stored program architectures should treat this patent family as a potential assertion risk. S3G Technology’s willingness to file in E.D. Texas and pursue multiple defendants simultaneously suggests a commercially active enforcement posture.
Should your mobile app team run an FTO against US9940124B2 and related patents?
Any company operating a customer-facing mobile application — particularly in QSR, retail, loyalty programs, or food and beverage delivery — that runs on Android or iOS and involves server-side processing or stored software execution methods should consider an FTO analysis against this four-patent portfolio. The breadth of the accused product description in this case (systems, methods, servers, software, non-transitory storage media) signals that S3G Technology is asserting wide claim coverage.
PatSnap Eureka’s FTO Search Agent can map your product architecture against the claim scope of US9940124B2, US11662995B2, US9304758B2, and US10387140B2 simultaneously, identify prior art relevant to validity challenges, and flag continuation applications that may extend this family. Running an FTO before product launch or redesign is significantly less costly than responding to an E.D. Texas complaint on an accelerated timeline.

What this case signals for the mobile app and QSR IP landscape
A 76-day resolution in E.D. Texas with prejudice and an open lead case reveals a calculated patent assertion strategy worth monitoring.
S3G’s open lead case suggests a multi-defendant assertion campaign is ongoing
The court’s order explicitly directed the clerk to maintain the lead case as open. This structure — a consolidated lead case with member cases against individual defendants — is a hallmark of coordinated patent assertion campaigns. Other companies deploying mobile app platforms similar to Smoothie King’s should assess whether S3G’s four patents cover their technology stack.
Own-costs dismissal with prejudice typically signals a licensing resolution
When both parties bear their own costs and agree to a with-prejudice dismissal, the most commercially logical explanation is a licensing agreement or lump-sum payment. No public record of financial terms exists, but the speed and structure of resolution — 76 days, joint motion, own costs — is consistent with a negotiated exit rather than defendant-side capitulation.
S3G v Smoothie — key questions answered
S3G Technology filed a patent infringement suit against Smoothie King Franchises in the Eastern District of Texas on May 22, 2025, asserting four mobile app patents. The case was dismissed with prejudice on August 6, 2025, after a joint motion by both parties, with each side bearing its own costs. No finding of infringement or invalidity was made.
S3G Technology asserted four U.S. patents: US9940124B2, US11662995B2, US9304758B2, and US10387140B2. All four relate to mobile application execution technology covering Android and iOS platforms, including systems, methods, computing devices, servers, software, and non-transitory computer-readable storage media.
Dismissal with prejudice means S3G Technology is permanently barred from re-asserting these four patents against Smoothie King Franchises in any future litigation. It does not mean the patents are invalid — they remain enforceable against third parties. The dismissal reflects a final resolution of claims between these two specific parties only.
The 76-day resolution — from filing to dismissal — is notably fast for a multi-patent infringement case in E.D. Texas. While the public record does not disclose financial terms, the joint motion, with-prejudice dismissal, and own-costs structure are consistent with a negotiated licensing or settlement agreement reached shortly after filing. The open lead case further suggests a pre-existing litigation programme.
The court’s order in this case explicitly directed the clerk to maintain the lead case as open, indicating that Case No. 2:25-cv-00581 was a member case within a broader consolidated docket. This structure typically indicates multiple defendants are or have been named in parallel actions under the same patent portfolio, though the public record does not identify other specific defendants at this time.
