Fall Line Patents v. Advance Auto Parts: Dismissed With Prejudice After 268 Days
Fall Line Patents, LLC sued Advance Auto Parts, Inc. in the Eastern District of Texas, asserting US9454748B2 — a patent covering location-specific mobile questionnaire systems — against the Advance Auto Parts mobile app. The case ended with a voluntary dismissal with prejudice under Rule 41, with each party bearing its own fees and costs.
Patent NPE targets mobile app order-and-location tech in E.D. Texas
Fall Line Patents, LLC — a non-practising entity — filed suit against Advance Auto Parts, Inc. and Advance Stores Company, Inc. on 25 November 2024 in the Eastern District of Texas (Case No. 5:24-cv-00170), asserting infringement of US9454748B2. The patent covers systems and methods for generating and executing location-specific questionnaires via mobile applications, and Fall Line alleged the Advance Auto Parts mobile app — used to direct customers to stores, receive orders, and collect location-aware responses — fell within those claims.
The case closed on 20 August 2025 when Fall Line filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted the notice and ordered the claims dismissed with prejudice, meaning Fall Line is permanently barred from reasserting the same infringement claims against these defendants on this patent. Each party was ordered to bear its own attorney’s fees, costs, and expenses — no fee-shifting was awarded to either side.
At 268 days, the case resolved without a merits ruling, which is consistent with a confidential settlement or licensing agreement reached before significant motion practice or trial preparation concluded. The with-prejudice designation is notably stronger than a standard voluntary dismissal and may reflect a negotiated term. The absence of fee-shifting and the use of Rule 41(a)(1)(A)(i) — which requires no court order — suggests the parties reached resolution before the defendant had served an answer or summary judgment motion, though the public record does not confirm the commercial terms.

Dismissed with prejudice: what the Rule 41 termination means for both parties
Rule 41(a)(1)(A)(i) dismissal with prejudice explained
Under FRCP 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case without a court order by filing a notice before the defendant serves an answer or motion for summary judgment. Here, the court accepted the notice and imposed a with-prejudice designation — meaning the dismissal operates as a final adjudication on the merits. Fall Line cannot re-file the same infringement claims against these defendants on US9454748B2 in any federal court.
Permanent bar on refilingWith prejudice: this is not a standard voluntary dismissal
A voluntary dismissal under Rule 41(a)(1)(A)(i) is ordinarily without prejudice by default unless the plaintiff previously dismissed the same claim. The with-prejudice outcome here is stronger — it forecloses any future suit on the same claims. This designation likely reflects a negotiated term between the parties, though the public record does not disclose whether a settlement or licence agreement underpins the resolution.
No re-filing permittedFall Line surrenders future enforcement rights against this defendant
By accepting a with-prejudice dismissal, Fall Line Patents permanently relinquishes its right to pursue Advance Auto Parts and Advance Stores Company on the US9454748B2 claims raised here. While this closes enforcement against this defendant, Fall Line’s patent remains in force and may still be asserted against other parties in the mobile app and retail technology space.
Patent still active vs. third partiesAdvance Auto Parts achieves litigation certainty on these claims
The with-prejudice dismissal and mutual fee-bearing order provide Advance Auto Parts with finality: no exposure to renewed litigation by Fall Line on this patent for the accused mobile app functionality. However, the order does not constitute a validity or non-infringement ruling, so the patent’s scope is unresolved as a matter of law and may affect how Advance Auto Parts documents its FTO position for similar future features.

Official order — verbatim text
The court’s order accepts Fall Line’s Rule 41(a)(1)(A)(i) notice and imposes dismissal with prejudice — a final disposition that bars re-litigation of these specific claims against these defendants. Critically, the order also moots all pending motions in the member case, suggesting substantive proceedings were underway. The mutual fee-bearing instruction is consistent with a negotiated exit rather than a contested dismissal. No merits finding — on infringement or validity — was made, leaving the patent’s enforceability against third parties entirely intact.
US9454748B2 — Location-specific mobile questionnaire and ordering system
US9454748B2, filed under application number US12/910706, claims systems and methods for creating and executing location-specific questionnaires through mobile applications — enabling apps to direct customers to nearby stores and collect location-aware responses to facilitate order processing. The patent sits at the intersection of mobile computing, geolocation, and retail commerce workflows, covering the dynamic generation of questionnaires tailored to a user’s physical location and store proximity.
For automotive aftermarket retailers and any mobile commerce operator, this patent represents a meaningful enforcement risk. The claimed functionality — using location data to customise in-app questionnaires and route customer orders to specific store locations — is broadly consistent with how modern retail apps handle store-finding, appointment scheduling, and localised order intake. Fall Line’s decision to assert this patent against a major national retailer suggests confidence in claim scope, and the absence of any invalidity ruling leaves the patent in force for enforcement against competitors or adjacent market participants.
Should your mobile retail app team run an FTO against US9454748B2?
Any company operating a mobile app that uses geolocation data to customise user questionnaires, direct customers to specific retail locations, or process location-specific orders should assess its exposure to US9454748B2. The accused functionality in this case — routing customers to stores and collecting location-aware responses — describes features common across automotive, home improvement, pharmacy, and general retail app ecosystems. No claim construction is on record, meaning the patent’s reach has not been judicially narrowed.

What this case signals for the mobile retail app IP landscape
NPE enforcement targeting location-aware mobile commerce features is active in E.D. Texas — and with-prejudice resolutions raise the stakes for each defendant.
Fall Line’s US9454748B2 remains enforceable against other mobile retail apps
This dismissal resolves only Fall Line’s claims against Advance Auto Parts. The patent itself is unscathed — no invalidity ruling, no claim construction. Any retailer operating a mobile app that uses location data to generate store-specific questionnaires or order flows should treat this patent as an active enforcement risk and consider an FTO review.
E.D. Texas NPE suits often resolve pre-answer — monitor early filing patterns
The Rule 41(a)(1)(A)(i) mechanism suggests this case settled before Advance Auto Parts formally answered. NPE plaintiffs in E.D. Texas frequently file serially against multiple defendants. In-house IP teams at mobile commerce companies should monitor Fall Line’s docket for co-pending or follow-on actions targeting similar app functionality.
Fall v Advance — key questions answered
Fall Line Patents, LLC filed a patent infringement suit against Advance Auto Parts, Inc. in the Eastern District of Texas on 25 November 2024, asserting US9454748B2 against the Advance Auto Parts mobile app. The case was dismissed with prejudice on 20 August 2025 pursuant to Rule 41(a)(1)(A)(i), with each party bearing its own fees and costs. No merits ruling on infringement or validity was issued.
US9454748B2 covers systems and methods for generating location-specific questionnaires via mobile applications to direct customers to stores and collect location-aware order responses. Fall Line alleged the Advance Auto Parts mobile app — which routes customers to nearby stores and processes localised orders — practised these claims. No claim construction order was issued, so the precise scope of the patent as applied remains undefined.
A dismissal with prejudice under Rule 41 is a final adjudication barring Fall Line from re-filing the same infringement claims against Advance Auto Parts and Advance Stores Company on US9454748B2. For Advance Auto Parts, it provides litigation certainty. However, it is not a validity or non-infringement finding — the patent remains enforceable against other defendants.
Yes. The dismissal with prejudice binds only the named defendants — Advance Auto Parts, Inc. and Advance Stores Company, Inc. The patent US9454748B2 remains in force and Fall Line retains full enforcement rights against any other party. Companies operating mobile apps with location-specific questionnaire or order-routing features should consider this patent an active enforcement risk.
The court’s order that each party bear its own fees, costs, and expenses is consistent with a negotiated voluntary dismissal rather than a contested outcome. Neither party sought — or was awarded — fees under 35 U.S.C. § 285 (exceptional case standard). This mutual fee-bearing arrangement typically accompanies settlements or licensing resolutions where both sides agree to walk away without further financial claims.
