Fall Line Patents v. Carl’s Jr. & CKE: Infringement Claims Dismissed With Prejudice
Fall Line Patents, LLC asserted US9454748B2 — a patent covering a system and method for data management — against Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. in the Eastern District of Texas. The parties jointly moved to dismiss, resulting in plaintiff’s claims being dismissed with prejudice and defendants’ counterclaims dismissed without prejudice as moot. The case closed 460 days after filing, with each party bearing its own attorneys’ fees.
A patent assertion resolved by joint motion — no merits ruling reached
Fall Line Patents, LLC filed suit against Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. on July 11, 2024 in the Eastern District of Texas (Case No. 5:24-cv-00090), asserting infringement of US9454748B2, which covers a system and method for data management. The case was part of a broader coordinated filing by Fall Line Patents against multiple quick-service restaurant operators, including Raising Cane’s, Krispy Kreme, and El Pollo Loco, all consolidated under this lead docket.
The case closed on October 14, 2025, when the court granted a joint motion to dismiss filed by all parties. Plaintiff’s claims were dismissed with prejudice — meaning Fall Line Patents cannot re-assert the same claims against these defendants in a future action. Defendants’ counterclaims were dismissed without prejudice as moot, preserving defendants’ ability to revive those claims if circumstances change, though in practice the dismissal of plaintiff’s claims renders counterclaims academic.
The 460-day duration and the joint nature of the dismissal motion suggest the parties reached a private resolution, though the public record contains no settlement agreement or financial terms. The with-prejudice dismissal of plaintiff’s claims is a meaningful concession — it permanently bars re-litigation against these specific defendants. The decision to bear own costs, rather than seek fee-shifting under 35 U.S.C. § 285, is consistent with negotiated exits and suggests neither side pursued an ‘exceptional case’ determination.

Claims dismissed with prejudice: what the joint motion means for each party
With-prejudice dismissal permanently bars re-litigation
A dismissal with prejudice is a final adjudication on the merits — it operates as a complete bar against Fall Line Patents re-asserting the same patent claims against these defendants. Unlike a without-prejudice dismissal, which preserves the right to refile, this outcome extinguishes the cause of action permanently as to Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. The joint motion signals mutual agreement, but the with-prejudice term was a meaningful concession by plaintiff.
Permanent bar on re-filingFall Line Patents loses the right to re-sue these defendants
By agreeing to a with-prejudice dismissal of its claims, Fall Line Patents permanently forecloses future litigation against Carls Jr. and CKE on US9454748B2. This is an unusual concession for a patent assertion entity, and the public record does not disclose whether a confidential payment or licensing arrangement accompanied the dismissal. The with-prejudice term may reflect a settlement with compensation, or alternatively a strategic decision to exit litigation against a well-resourced defendant represented by Fish & Richardson.
Claims extinguished against defendantsCKE and Carl’s Jr. secure permanent immunity from these claims
Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. achieved the strongest possible litigation outcome short of an invalidity ruling: permanent dismissal of all plaintiff’s claims. Their counterclaims — likely invalidity or non-infringement defences — were dismissed without prejudice as moot, meaning defendants retain the ability to revive them if needed, though in practice the with-prejudice bar makes this unlikely. Fish & Richardson’s defence strategy appears to have pressured a favourable exit.
Permanent immunity from these claimsUS9454748B2 remains active — risk persists for other operators
The dismissal resolves liability only for the named defendants. US9454748B2 remains in force and Fall Line Patents’ coordinated campaign against multiple QSR chains — Raising Cane’s, Krispy Kreme, El Pollo Loco, and others — suggests an active enforcement programme. Restaurant operators using digital ordering, mobile data capture, or cloud-based data management systems should assess exposure to this patent. The absence of an invalidity ruling leaves the patent’s validity uncontested in this proceeding.

Official order — verbatim text
The court’s order grants a joint motion, reflecting no contested merits ruling — the outcome is entirely consent-driven. The asymmetric dismissal terms are legally significant: plaintiff’s claims dismissed with prejudice create a permanent estoppel, while defendants’ counterclaims dismissed without prejudice as moot preserve theoretical revival rights. The explicit ‘each party bears own fees’ instruction forecloses any future § 285 motion arising from this proceeding. The consolidated closure of member cases 5:24-CV-90, 92, 95, and 96 confirms this was a sector-wide coordinated resolution.
US9454748B2 — System and method for data management
US9454748B2 (application no. US12/910706) covers a system and method for data management, broadly encompassing data capture, processing, and management workflows across networked devices. The patent’s application number sequence suggests filing in the 2010–2011 timeframe, placing it within an era of rapid mobile and cloud-platform development. Patents in this class frequently assert broad method claims that can implicate a wide range of digital infrastructure, including mobile ordering platforms, customer data systems, and POS integrations.
For the quick-service restaurant sector, which has invested heavily in digital ordering, loyalty platforms, and cloud data management over the past decade, US9454748B2 represents a category of IP risk that is difficult to design around without a thorough claim analysis. Fall Line Patents’ decision to assert this patent against multiple major QSR chains simultaneously suggests confidence in claim breadth. The absence of any invalidity finding in this proceeding means the patent remains fully enforceable and poses ongoing risk to other operators in the sector.
Should you run an FTO against US9454748B2?
Any company operating a digital ordering system, mobile data management platform, or cloud-based customer data workflow in the restaurant, hospitality, or retail sector should assess exposure to US9454748B2. Fall Line Patents has demonstrated willingness to assert this patent broadly across the QSR industry, and the with-prejudice dismissal in this case provides no public guidance on which product features triggered the infringement allegations. R&D and product teams deploying new data capture or management functionality should prioritise FTO analysis before launch.

What this case signals for the QSR technology IP landscape
Fall Line’s coordinated restaurant-sector campaign over data management IP highlights growing PAE activity targeting digital infrastructure in hospitality and QSR.
PAE campaigns targeting QSR digital systems are accelerating
Fall Line Patents filed substantially identical suits against at least four QSR operators simultaneously. This coordinated approach — common for patent assertion entities — allows cost-efficient litigation across a sector. Restaurant and hospitality operators adopting digital ordering, mobile apps, or cloud data management should treat this case as a sector-wide risk signal, not an isolated dispute.
With-prejudice dismissal without cost-shifting suggests negotiated exit
The combination of plaintiff’s claims dismissed with prejudice, defendants’ counterclaims dismissed without prejudice, and each party bearing own costs is a classic signature of a confidential settlement. Neither side sought § 285 fees, consistent with a mutual decision to exit cleanly. IP teams should note that this resolution provides no public guidance on royalty rates or claim scope.
Fall v Carls — key questions answered
Fall Line Patents, LLC asserted US9454748B2 against Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. in the Eastern District of Texas. The parties filed a joint motion to dismiss, which the court granted on October 14, 2025. Plaintiff’s claims were dismissed with prejudice; defendants’ counterclaims were dismissed without prejudice as moot. Each party bears its own attorneys’ fees and costs.
A with-prejudice dismissal permanently extinguishes Fall Line Patents’ ability to re-assert the same patent claims (US9454748B2) against Carls Jr. Restaurants LLC and CKE Restaurants Holdings, Inc. in any future proceeding. It operates as a final judgment on the merits for purposes of claim preclusion, even though no trial or merits ruling occurred. Fall Line Patents may continue to assert this patent against other defendants not covered by this order.
Yes. The dismissal resolves liability only for the named defendants in this consolidated action. No invalidity finding was made, and the patent’s validity was not adjudicated. US9454748B2 remains in force and enforceable against other parties. Fall Line Patents’ coordinated campaign across multiple QSR operators suggests active ongoing enforcement intentions.
When a plaintiff’s claims are dismissed with prejudice, any invalidity or non-infringement counterclaims filed by defendants become moot — there is no longer an active infringement claim to defend against. The without-prejudice designation preserves defendants’ theoretical right to revive those counterclaims if circumstances change, though in practice the with-prejudice bar on plaintiff’s claims makes revival unlikely in this specific dispute.
Fall Line Patents filed coordinated infringement actions against multiple quick-service restaurant operators asserting US9454748B2, including Raising Cane’s, Krispy Kreme, and El Pollo Loco, all consolidated under this lead case in the Eastern District of Texas. The joint dismissal motion resolved claims against all named defendant groups simultaneously, with member cases 5:24-CV-90, 92, 95, and 96 all closed by the same order.
