Fall Line Patents v. El Pollo Loco: Mobile App Patent Claims Dismissed With Prejudice
Patent assertion entity Fall Line Patents, LLC sued El Pollo Loco, Inc. and its parent holding company over US9454748B2, a patent covering mobile ordering application technology. The case, filed in the Eastern District of Texas and consolidated with related actions against Raising Cane’s, Krispy Kreme, and Carl’s Jr., ended after 460 days when all parties jointly moved to dismiss — plaintiff’s claims with prejudice, defendants’ counterclaims without prejudice as moot.
Consolidated restaurant-tech patent suit ends in finality for defendants
Fall Line Patents, LLC — a non-practicing entity — filed suit on July 11, 2024 in the Eastern District of Texas against El Pollo Loco, Inc. and EL Pollo Loco Holdings, Inc., asserting infringement of US9454748B2 in connection with the El Pollo Loco mobile app. The case was part of a coordinated campaign by Fall Line targeting multiple quick-service restaurant chains, with parallel actions filed against Raising Cane’s, Krispy Kreme, and Carl’s Jr. in the same court under a consolidated lead docket.
The case closed on October 14, 2025, after all parties — across all consolidated member cases — filed a joint motion to dismiss. Judge Robert W. Schroeder III granted the motion in full: plaintiff’s claims were dismissed with prejudice, permanently barring Fall Line from refiling the same infringement claims against these defendants. Defendants’ counterclaims were dismissed without prejudice as moot, preserving their ability to assert those claims in future proceedings should circumstances change. Each party was ordered to bear its own attorneys’ fees and costs, consistent with a negotiated resolution rather than a merits adjudication.
The 460-day duration and the with-prejudice dismissal of plaintiff’s claims — combined with the fee-neutral cost order — is consistent with a confidential settlement or licensing resolution across the consolidated defendant group, though the public record does not confirm settlement terms or any financial exchange. The coordinated joint motion across four consolidated cases suggests the parties reached a unified resolution. What drove the outcome — whether claim construction risk, prior art exposure, or commercial licensing pragmatism — is not disclosed in the public record.

Dismissed with prejudice: what the joint motion outcome means for each party
With-prejudice dismissal permanently bars refiling
A dismissal with prejudice is a final adjudication on the merits for procedural purposes. Fall Line Patents cannot refile the same US9454748B2 infringement claims against El Pollo Loco or its holding company in any court. The joint motion mechanism — where both sides agree to the terms — suggests the outcome was negotiated rather than imposed, and the court simply ratified the parties’ agreed resolution.
Claim preclusion appliesFall Line loses right to re-assert these claims against El Pollo Loco
By agreeing to a with-prejudice dismissal, Fall Line Patents permanently surrendered its infringement claims under US9454748B2 against these specific defendants. This is an unusual concession for a patent assertion entity unless consideration was received — typically suggesting a licensing payment or other commercial arrangement. The public record does not disclose whether Fall Line received any compensation; the cost-neutral order neither confirms nor excludes a settlement.
No re-filing permittedEl Pollo Loco secures permanent release from these patent claims
El Pollo Loco and EL Pollo Loco Holdings achieved a with-prejudice dismissal — the strongest procedural outcome short of a judgment of non-infringement or invalidity. Their counterclaims were dismissed without prejudice as moot, preserving optionality. The fee-neutral cost order means defendants absorbed their own legal costs, consistent with a commercial resolution. Fish & Richardson and Vorys, Sater represented the defendants throughout.
Counterclaims preserved as mootCoordinated resolution across four QSR defendants signals licensing strategy
The simultaneous joint dismissal across Raising Cane’s, Krispy Kreme, El Pollo Loco, and Carl’s Jr. suggests Fall Line pursued a portfolio licensing campaign targeting the quick-service restaurant sector’s mobile ordering infrastructure. The coordinated outcome — all cases closed on the same order — is consistent with a group licensing arrangement or unified defence strategy. Other restaurant operators using similar mobile app technology should assess their exposure to US9454748B2.

Official order — verbatim text
The court’s order reflects a fully consensual resolution: all parties jointly moved to dismiss, and Judge Schroeder granted the motion without substantive merits analysis. The asymmetric dismissal terms — plaintiff’s claims with prejudice, defendants’ counterclaims without prejudice as moot — are legally significant. The with-prejudice designation operates as a final judgment for claim-preclusion purposes, while the moot counterclaim dismissal leaves defendants’ declaratory judgment and invalidity positions legally unresolved but practically extinguished by the underlying resolution.
US9454748B2 — Mobile order-entry and data capture application technology
US9454748B2 (application no. US12/910706) covers technology in the domain of mobile application order-entry and structured data capture — the type of workflow central to consumer-facing restaurant ordering apps. The patent’s claims are directed to capturing and processing user-entered data through mobile interfaces, a foundational capability in modern QSR digital ordering platforms. Its assertion against multiple restaurant chains simultaneously suggests the claims are drafted broadly enough to potentially read on standard mobile app architectures.
The strategic significance of US9454748B2 lies in its applicability to any food-service or retail operator running a branded mobile ordering app — a category that now encompasses virtually every major QSR chain. Fall Line’s ability to file and consolidate actions against four separate defendants in E.D. Texas suggests the patent has sufficient claim breadth to create credible infringement theories across different mobile app implementations. Competitors and adjacent-sector operators in retail, hospitality, and food delivery should treat this patent as a live monitoring priority.
Should you run an FTO against US9454748B2?
Any company operating a mobile ordering application — particularly in the quick-service restaurant, fast-casual dining, food delivery, or retail sectors — should assess whether US9454748B2 poses a freedom-to-operate risk. The patent’s assertion against El Pollo Loco, Raising Cane’s, Krispy Kreme, and Carl’s Jr. in a single consolidated action confirms that the patent holder views its claims as applicable across varied mobile app implementations. A proactive FTO analysis is especially warranted for operators that have recently launched or upgraded digital ordering platforms.
PatSnap Eureka’s FTO Search Agent allows IP and R&D teams to map US9454748B2’s independent claims against their product architecture, identify prior art that could support an IPR petition, and surface related Fall Line portfolio assets that may pose additional risk. Eureka’s claim-chart generation and prior-art clustering tools are designed for exactly this type of NPE portfolio clearance — giving in-house counsel a defensible, documented FTO position before a demand letter arrives.

What this case signals for the restaurant-tech and mobile ordering IP landscape
A coordinated four-defendant dismissal in E.D. Texas confirms that mobile ordering patents remain active assertion targets for NPEs across the QSR sector.
NPEs are actively targeting QSR mobile app infrastructure — assess your exposure now
Fall Line’s consolidated campaign against four major quick-service restaurant chains over a single mobile ordering patent demonstrates that NPEs are systematically targeting the restaurant sector’s digital infrastructure. Any operator running a branded mobile ordering or loyalty app should evaluate whether US9454748B2 — or related patents in Fall Line’s portfolio — reads on their technology stack.
With-prejudice joint dismissals in E.D. Texas typically signal a licensing resolution
When a patent assertion entity agrees to dismiss claims with prejudice while accepting a fee-neutral cost order, the pattern is strongly consistent with a confidential licensing payment. IP teams tracking Fall Line Patents should note this outcome as evidence that the NPE is actively monetising US9454748B2 across the QSR vertical — and may have established a licensing rate that informs future demand letters.
Fall v El — key questions answered
The case was dismissed pursuant to a joint motion by all parties. Fall Line Patents’ infringement claims were dismissed with prejudice, permanently barring refiling against El Pollo Loco and its holding company. Defendants’ counterclaims were dismissed without prejudice as moot. Each party bore its own attorneys’ fees and costs. The case closed on October 14, 2025, after 460 days.
A with-prejudice dismissal operates as a final adjudication for claim-preclusion purposes. Fall Line Patents cannot refile the US9454748B2 infringement claims against El Pollo Loco, Inc. or EL Pollo Loco Holdings, Inc. in any federal court. The parties jointly agreed to this term, which is typically consistent with a negotiated resolution — often involving a licensing payment — though the public record does not confirm any financial terms.
Fall Line Patents asserted US9454748B2 (application no. US12/910706), a patent covering mobile application order-entry and structured data capture technology. The patent was asserted in connection with the El Pollo Loco mobile app. The same patent was simultaneously asserted against Raising Cane’s, Krispy Kreme, and Carl’s Jr. in consolidated actions in the Eastern District of Texas.
The Eastern District of Texas — specifically the Texarkana Division before Judge Robert W. Schroeder III — has historically been a preferred venue for patent assertion entities due to its established patent litigation procedures and jury pool. Fall Line Patents filed consolidated actions against at least four QSR defendants in this court, suggesting a deliberate venue strategy designed to maximise settlement pressure through efficient multi-defendant litigation.
The simultaneous targeting of four major QSR brands over a single mobile ordering patent signals that NPEs view the restaurant sector’s digital infrastructure as a viable assertion target. Any operator running a consumer-facing mobile ordering app should consider running a freedom-to-operate analysis against US9454748B2 and monitoring Fall Line’s broader patent portfolio for related continuation or divisional applications that could support future demand letters.
