Fall Line Patents v. Best Buy: Infringement Claims Dismissed With Prejudice
Fall Line Patents, LLC filed suit against Best Buy Co., Inc. in the Eastern District of Texas, asserting US9454748B2 — a patent covering location-specific mobile questionnaire and ordering functionality — against the Best Buy Mobile App. The parties jointly moved to dismiss all claims with prejudice after 379 days, permanently closing the matter as to Best Buy.
Joint dismissal ends Fall Line’s mobile app patent push against Best Buy
On November 25, 2024, Fall Line Patents, LLC — a patent assertion entity — filed Case No. 5:24-cv-00174 in the U.S. District Court for the Eastern District of Texas before Judge Robert W. Schroeder, III. Fall Line asserted US9454748B2 (App. No. 12/910706), a patent directed to systems and methods for generating and executing location-specific questionnaires on mobile devices, against Best Buy’s consumer-facing mobile application and its associated server infrastructure used to route orders to physical store locations.
The case closed on December 9, 2025, when the Court granted a joint motion to dismiss filed by Fall Line and the named Best Buy defendants — BestBuy.com, LLC and Best Buy Texas.com, LLC. All of Fall Line’s infringement claims were dismissed with prejudice, permanently barring re-filing on the same claims. Best Buy’s counterclaims were simultaneously dismissed as moot. The member case (5:24-cv-174) was closed, though the lead consolidated action was noted to remain open, suggesting Fall Line may have parallel proceedings against other defendants.
A 379-day lifespan ending in a joint dismissal with prejudice is consistent with a confidential settlement reached before trial — the ‘with prejudice’ designation typically reflects agreed finality rather than a contested adjudication. The public record does not disclose financial terms, licensing agreements, or any admission of liability. It remains unknown whether Best Buy obtained a license, paid a lump sum, or negotiated a walk-away. The reference to a surviving consolidated lead case suggests Fall Line’s broader campaign under US9454748B2 against other defendants continues.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice permanently bars re-filing these claims
A dismissal with prejudice under Federal Rule of Civil Procedure 41 operates as a final judgment on the merits. Fall Line cannot re-assert the same infringement claims under US9454748B2 against Best Buy in any future action. The joint nature of the motion signals mutual agreement — neither party was forced to this outcome by the Court — which is the hallmark structure of a negotiated resolution.
Permanent bar on re-litigationFall Line forfeits future claims against Best Buy — likely in exchange for consideration
By agreeing to dismiss with prejudice, Fall Line permanently surrendered its right to sue Best Buy again on these claims. Patent assertion entities rarely accept this outcome without receiving something in return. The public record is silent on whether a license fee, lump-sum payment, or other consideration was exchanged. The continued existence of the consolidated lead case suggests Fall Line’s broader assertion strategy under US9454748B2 remains active against other defendants.
Possible confidential settlementBest Buy achieves finality — counterclaims dismissed as moot
Best Buy secured a permanent end to this specific litigation. Its counterclaims — which may have included invalidity or non-infringement defenses — were dismissed as moot, meaning the Court made no ruling on their merits. This is typical where a settlement resolves the underlying dispute before counterclaims are adjudicated. Best Buy avoids any public admission of infringement, and the dismissal-as-moot preserves its ability to raise invalidity arguments in other venues if needed.
Clean exit, no merits rulingUS9454748B2 remains in force — other mobile app defendants remain exposed
The dismissal resolves only the Best Buy member case. The consolidated lead action remains open, suggesting Fall Line is pursuing other defendants under the same patent. Retailers and app developers whose mobile platforms use location-aware questionnaire flows or store-directed ordering should treat US9454748B2 as an active enforcement risk. The with-prejudice resolution here neither validates nor invalidates the patent’s claims — it leaves enforceability fully intact against non-settling parties.

Official order — verbatim text
The Court’s order grants a joint motion, meaning the dismissal was sought by both parties — not imposed unilaterally. The with-prejudice designation is legally significant: it carries the force of a final judgment on the merits, extinguishing Fall Line’s claims against these specific Best Buy entities permanently. The simultaneous dismissal of Best Buy’s counterclaims as moot confirms no substantive adjudication of validity or infringement occurred. The order’s preservation of the lead consolidated case is a material signal that parallel proceedings under the same patent continue.
US9454748B2 — Location-specific mobile questionnaire and ordering systems
US9454748B2 (filed under Application No. 12/910706) covers systems and methods for creating and executing location-specific questionnaires on mobile devices — enabling applications to tailor data collection and ordering flows based on a user’s proximity to or association with a physical store location. The patent’s technical scope encompasses the interaction between a mobile client, remote servers, and location context to generate dynamic, store-specific user experiences, which maps directly onto the Best Buy Mobile App’s functionality as alleged in this action.
From a competitive intelligence standpoint, US9454748B2 represents a meaningful risk for any retailer or platform operator whose mobile application uses location signals to personalise questionnaires, surveys, in-app ordering flows, or store-specific content delivery. Fall Line’s willingness to file in E.D. Texas and pursue multiple consolidated defendants suggests an active monetisation campaign. Companies operating in omnichannel retail, quick-service restaurant ordering, or any app-based location-triggered data collection should assess their exposure to this patent’s claim scope before receiving a demand letter.
Should you run an FTO against US9454748B2?
Any product team building or maintaining a mobile application that uses location context to drive questionnaire flows, store-specific ordering, or personalised data collection should treat US9454748B2 as a priority FTO target. Fall Line has demonstrated both the willingness to litigate and the ability to secure resolutions in E.D. Texas — a venue where litigation costs alone can dwarf licensing fees. The consolidated nature of this action suggests multiple defendants are already engaged, raising the probability that the patent is being asserted broadly across the retail and hospitality technology sectors.
PatSnap Eureka’s FTO Search Agent can map the full claim scope of US9454748B2 against your application’s architecture, identify prior art that may undermine enforceability, and surface any IPR petitions or prosecution history that could inform a design-around or challenge strategy. Running a structured FTO now — before receiving a demand — is significantly more cost-effective than defending in E.D. Texas. Eureka can also monitor Fall Line Patents’ broader portfolio and docket activity to give your team early warning of new assertion targets.

What this case signals for the mobile app and retail technology IP landscape
Fall Line’s targeted action against Best Buy’s mobile ordering infrastructure reflects a broader enforcement pattern around location-aware application patents.
E.D. Texas remains a high-pressure venue for retail technology patent defendants
The Eastern District of Texas continues to attract patent assertion entities targeting consumer-facing mobile and e-commerce infrastructure. Filing in this venue imposes significant litigation cost on defendants, often incentivising early resolution regardless of the underlying merits. Retailers with mobile apps should factor this venue risk into IP risk assessments.
Joint dismissal with prejudice is the structural signature of a confidential settlement
When both parties jointly move to dismiss with prejudice — without a trial, summary judgment, or any merits ruling — the most commercially plausible explanation is a negotiated resolution with undisclosed terms. In-house counsel should treat this outcome as a settlement datapoint when benchmarking exposure for similar patent assertions against mobile ordering and location-based app features.
Fall v Best — key questions answered
Fall Line Patents, LLC filed a patent infringement action against Best Buy Co., Inc. in the Eastern District of Texas on November 25, 2024, asserting US9454748B2 against the Best Buy Mobile App. The case was dismissed with prejudice on December 9, 2025, pursuant to a joint motion by both parties. Best Buy’s counterclaims were dismissed as moot. No merits ruling was issued.
US9454748B2 covers systems and methods for generating and executing location-specific questionnaires on mobile devices, including interactions between a mobile client and servers to create store-directed user experiences. Fall Line alleged the Best Buy Mobile App used this technology to direct customers to stores and collect location-specific order information — mapping the patent’s claims onto core mobile ordering functionality.
Dismissal with prejudice operates as a final judgment on the merits under Federal Rule of Civil Procedure 41. Fall Line permanently loses the right to re-assert the same claims under US9454748B2 against the Best Buy entities named in this action. The joint nature of the motion strongly suggests a negotiated resolution, though no financial terms are disclosed in the public record.
Based on the Court’s order, the consolidated lead case remains open after the Best Buy member case was closed. This suggests Fall Line is pursuing additional defendants under the same patent in coordinated litigation. Companies operating mobile apps with location-specific ordering or questionnaire features should monitor the consolidated docket and assess their own exposure to US9454748B2.
No. Best Buy’s counterclaims were dismissed as moot — meaning the Court never adjudicated their substance. No invalidity ruling was issued. US9454748B2 remains presumptively valid. Other defendants facing Fall Line’s assertions would need to raise invalidity independently, including through an inter partes review petition at the USPTO, which remains available within one year of service of a complaint.
