Fall Line Patents v. Wingstop: Mobile App Patent Suit Dismissed After 526 Days
Patent assertion entity Fall Line Patents, LLC sued Wingstop Inc. and related entities in the Eastern District of Texas, alleging infringement of US9454748B2 through the Wingstop mobile ordering app. The case closed December 19, 2025, when the court granted a joint motion to dismiss — one of several coordinated dismissals across a broader multi-defendant campaign targeting restaurant chains.
PAE targets Wingstop mobile ordering app in coordinated E.D. Tex. campaign
On July 11, 2024, Fall Line Patents, LLC — a patent assertion entity — filed suit in the U.S. District Court for the Eastern District of Texas (Case No. 5:24-cv-00089) against Wingstop Inc., Wingstop Restaurants Inc., and Wingstop Franchising LLC. The sole patent asserted was US9454748B2 (application no. 12/910706), which covers mobile data-entry and form-based ordering technology. The accused product was the Wingstop mobile app, which enables customers to place food orders digitally.
The case closed on December 19, 2025, when Judge Robert W. Schroeder III granted a joint motion to dismiss filed by Fall Line Patents and the so-called ‘Remaining Defendants,’ which included not only the Wingstop entities but also co-defendants from parallel proceedings — Raising Cane’s, Krispy Kreme, El Pollo Loco, and Carl’s Jr. The court ordered all pending motions denied as moot and directed the clerk to close the lead case. The basis of termination is recorded simply as ‘Case Dismissed,’ without specifying with or without prejudice in the publicly available order text.
At 526 days, the case ran longer than many PAE actions that settle early, suggesting substantive litigation activity before resolution. The coordinated multi-defendant dismissal — spanning several well-known quick-service restaurant brands — is consistent with a global settlement or licensing resolution, though the public record does not confirm financial terms. What drove the ultimate dismissal, and whether licenses were granted, remains undisclosed.
Filing to Case Dismissed in 526 days
526 days to dismissal — above the median for E.D. Tex. patent cases resolved without trial
Joint dismissal granted: what the court order means for both parties
Joint motion to dismiss: a consensual procedural end
A joint motion to dismiss is filed by all parties together, signalling that the dispute has been resolved or that both sides agree the case should end. The court’s role is largely ministerial — it grants the motion and closes the docket. Crucially, the public order does not specify whether dismissal was with or without prejudice, meaning the preclusive effect on future claims against these defendants is uncertain from the public record alone.
Consensual dismissalWith or without prejudice? The public record is silent
A dismissal with prejudice bars Fall Line from re-asserting US9454748B2 against Wingstop on the same claims — it is a final adjudication on the merits. A dismissal without prejudice would leave that door open. The court order simply states ‘Case Dismissed’ following a joint motion, and does not specify either qualifier. Practitioners should treat the preclusive scope as legally uncertain absent a review of the full settlement or stipulation filed with the court.
Prejudice status unclearFall Line Patents exits with undisclosed terms
Fall Line Patents pursued a coordinated campaign across multiple restaurant-chain defendants simultaneously. The fact that dismissal was joint and covered defendants from several parallel cases — Raising Cane’s, Krispy Kreme, El Pollo Loco, Carl’s Jr., and Wingstop — is consistent with a portfolio licensing resolution. However, no financial terms, royalty rates, or licensing agreements appear in the public docket, so the commercial outcome for Fall Line remains unknown.
Terms undisclosedWingstop avoids trial but faces no confirmed clearance
Wingstop and its affiliated entities successfully exited the litigation without a liability finding or injunction. Represented by Fish & Richardson, a firm with deep patent litigation experience, the defendants appear to have reached a negotiated resolution. Without a confirmed prejudice designation or public license, Wingstop cannot be certain that Fall Line — or a successor holding US9454748B2 — will not assert the patent again in a different context.

Official order — verbatim text
The December 19, 2025 order is brief and procedural: the court granted the joint motion to dismiss and closed the lead docket. Notably, the order groups Wingstop with defendants from parallel cases — Raising Cane’s, Krispy Kreme, El Pollo Loco, and Carl’s Jr. — suggesting the dismissal was coordinated across related proceedings. The absence of any prejudice designation or merits ruling means this order resolves the case administratively rather than substantively, leaving the patent’s validity and the defendants’ infringement position formally unadjudicated.
US9454748B2 — Mobile data-entry and form-based ordering technology
US9454748B2 (application no. 12/910706) covers technology in the domain of mobile data-entry and form-based ordering — the type of structured input flow used when a customer selects items, customises an order, and submits it through a mobile application. The patent’s application number places it in a filing cohort consistent with early smartphone-era mobile commerce infrastructure, a period when foundational mobile UX patterns were being actively patented. Fall Line Patents has asserted this patent across multiple consumer-facing mobile ordering platforms.
For the quick-service restaurant sector, US9454748B2 represents a strategically placed patent: virtually every major QSR brand has invested heavily in mobile ordering as a revenue and loyalty channel. A patent covering the data-entry mechanics of such ordering flows creates broad potential exposure across the industry. The coordinated assertion against Wingstop, Raising Cane’s, Krispy Kreme, El Pollo Loco, and Carl’s Jr. simultaneously suggests Fall Line views this as a scalable enforcement asset — and that the patent’s claim scope is broad enough to map onto diverse mobile app implementations.
Should your team run an FTO analysis against US9454748B2?
Any company operating a consumer-facing mobile app that involves structured data entry for ordering — including food delivery, retail e-commerce, hospitality booking, or similar form-based flows — should consider an FTO analysis against US9454748B2 and its patent family. Fall Line’s demonstrated willingness to assert this patent against multiple large brands simultaneously suggests the patent holder views the claim scope as broad and licensable at scale. Waiting for a demand letter is the costlier path.
PatSnap Eureka’s FTO Search Agent can map the claim language of US9454748B2 against your product’s technical architecture, identify prior art that may undermine enforceability, and surface related continuations or family members you may also need to clear. For R&D and product teams building or updating mobile ordering functionality, running this analysis before launch reduces both litigation risk and negotiating leverage asymmetry if a demand does arrive.

Portfolio viewWhat this case signals for the mobile ordering and restaurant tech IP landscape
Fall Line’s multi-defendant campaign against QSR chains highlights the ongoing PAE risk for restaurant brands built on mobile ordering infrastructure.
Mobile app ordering patents remain a live PAE enforcement vector
US9454748B2 was asserted against at least five major quick-service restaurant brands in coordinated E.D. Tex. filings. Any company operating a consumer-facing mobile ordering app — particularly in food service, retail, or hospitality — should treat form-based and data-entry ordering patents as an active risk category requiring FTO analysis.
E.D. Texas remains the preferred venue for PAE mobile tech campaigns
Fall Line’s choice of the Eastern District of Texas is consistent with the court’s reputation for patent-plaintiff-friendly docket management. Companies with mobile commerce exposure should factor venue risk into litigation budgeting and consider proactive invalidity analysis of asserted patents before suit is filed.
Coordinated multi-defendant dismissal suggests portfolio licence resolution
When a PAE dismisses claims against five defendants simultaneously via joint motion, it typically signals a cross-defendant licensing deal rather than individual settlements. Monitoring Fall Line’s subsequent assertion activity against US9454748B2 will reveal whether royalty rates were set and what the effective licensing floor looks like for this patent family.
US9454748B2 parent application history may reveal claim scope vulnerabilities
Application no. 12/910706 has a prosecution history that may contain claim-narrowing arguments useful for IPR or ex parte reexamination. Companies still exposed to this patent — or continuations in the same family — should audit the file wrapper before any licensing negotiation or litigation response.
Fall v Wingstop — key questions answered
Fall Line Patents asserted US9454748B2 (application no. 12/910706), a patent covering mobile data-entry and form-based ordering technology. The accused product was the Wingstop mobile app used for customer food ordering.
The case was resolved via a joint motion to dismiss filed by all parties. Judge Robert W. Schroeder III granted the motion on October 14, 2025, and the case was formally closed on December 19, 2025. The public order does not specify whether dismissal was with or without prejudice.
Yes. The joint dismissal order names defendants from parallel proceedings — Raising Cane’s, Krispy Kreme, El Pollo Loco, and Carl’s Jr. — alongside the Wingstop entities. This coordinated dismissal across multiple QSR brands is consistent with a portfolio-wide licensing resolution, though no terms are public.
Fall Line Patents was represented by Antonelli, Harrington & Thompson, LLP, with attorneys including Matthew J. Antonelli and Zachariah Harrington. Wingstop was represented by Fish & Richardson LLP, with attorneys including Neil J. McNabnay and Bret Thomas Winterle.
The public record does not specify whether the dismissal was with or without prejudice. A dismissal with prejudice would bar Fall Line from re-asserting the same patent claims against Wingstop. A dismissal without prejudice would not. Without access to the underlying stipulation or settlement agreement, the preclusive effect cannot be confirmed from publicly available documents alone.
