Fall Line Patents LLC v. Arbys Restaurant Group Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Fall Line Patents, LLC (Oklahoma)
- Defendant: Arby's Restaurant Group, Inc. (Delaware)
- Plaintiff’s Counsel: Antonelli, Harrington & Thompson LLP
- Case Identification: 5:23-cv-00110, E.D. Tex., 10/13/2023
- Venue Allegations: Plaintiff alleges venue is proper in the Eastern District of Texas because Defendant transacts business in the district, has committed alleged acts of infringement in the district, and maintains a regular and established place of business in the district in the form of at least one Arby's restaurant.
- Core Dispute: Plaintiff alleges that Defendant’s Arby's Mobile App, in conjunction with its backend servers, infringes a patent related to methods for managing and collecting location-specific data from remote devices.
- Technical Context: The technology relates to systems for creating and deploying data-collection applications, such as surveys or forms, on a variety of remote handheld devices, particularly in environments with intermittent network connectivity.
- Key Procedural History: The complaint notes that the asserted patent family has been the subject of prior litigation. In a case against Zoe's Kitchen, Inc., the court reportedly denied a motion to dismiss under 35 U.S.C. § 101 and later granted summary judgment of validity under § 101. The patent-in-suit has also survived multiple inter partes review (IPR) proceedings, which resulted in the cancellation of numerous claims but confirmed the patentability of the single claim asserted in this action, Claim 7.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,454,748 - "System and Method for Data Management," issued September 27, 2016
The Invention Explained
- Problem Addressed: The patent describes a technical landscape where developing software for remote handheld computers was difficult due to hardware and operating system fragmentation (’748 Patent, col. 1:49-2:2). Creating a single application that could run on devices from different manufacturers was challenging, often requiring separate, custom-compiled programs (’748 Patent, col. 2:41-44). Furthermore, these devices often operated in locations with limited or intermittent network connectivity, making real-time data transfer to a central server unreliable (’748 Patent, col. 3:64-4:1).
- The Patented Solution: The invention proposes a system using a common operating instruction set, or overlay, that allows a single application to run on otherwise incompatible devices (’748 Patent, col. 7:50-54). Questionnaires or forms are created on a central server and converted into "device-independent tokens" which are then sent to remote devices (’748 Patent, col. 13:51-54). This tokenized approach allows for incremental updates without recompiling the entire application and reduces the amount of data transmitted (’748 Patent, col. 4:36-39). The system is designed to be "loosely networked," meaning it stores data locally when a network connection is unavailable and transmits it once the connection is restored (’748 Patent, col. 5:7-12).
- Technical Importance: This approach aimed to solve the cross-platform compatibility problem for mobile data collection applications and improve their reliability in environments with poor network access (’748 Patent, col. 2:56-65; Compl. ¶7).
Key Claims at a Glance
- The complaint asserts independent claim 7 (Compl. ¶11).
- The essential elements of Claim 7 are:
- Designing a questionnaire with branching logic, customized for a particular location, on a first computer platform.
- The questionnaire must include at least one question that requests location identifying information.
- Automatically transferring the designed questionnaire to a "loosely networked computer having a GPS integral thereto."
- When the computer is at the particular location, executing the questionnaire.
- While executing, using the GPS to automatically provide location identifying information as a response.
- Automatically transferring responses in real-time to a central computer via the loose network.
- Making the transferred responses available via the Internet.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
- The "Arby's Mobile App" operating on customer mobile devices, in conjunction with Arby's backend servers (Compl. ¶10).
Functionality and Market Context
- The complaint alleges that the accused instrumentality allows Arby's to "create and execute a location-specific questionnaire to collect responses from users" (Compl. ¶10). It is also used to "direct customers to, and receive orders from customers for, one or more Arby's restaurants" (Compl. ¶5). The complaint does not provide specific technical details on how the app functions, such as the nature of the user interface or the specific mechanisms for handling location data and user input. No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
’748 Patent Infringement Allegations
| Claim Element (from Independent Claim 7) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| designing a questionnaire including at least one question said questionnaire customized for a particular location having branching logic on a first computer platform | Arby's, on its servers (the "first computer platform"), allegedly creates a "location-specific questionnaire" for its mobile app. | ¶10 | col. 14:49-53 |
| wherein at least one of said at least one questions requests location identifying information | The functionality is described as a "location-specific questionnaire," which suggests a request for location information. | ¶10 | col. 14:53-54 |
| automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto | Arby's distributes its mobile app to customer smartphones (the "loosely networked computer"), which are equipped with GPS capabilities. | ¶10 | col. 14:55-58 |
| when said loosely networked computer is at said particular location, executing said transferred questionnaire on said loosely networked computer | Customers download and use the Arby's Mobile App at specific locations to place orders. | ¶5, ¶14 | col. 14:59-62 |
| while said transferred questionnaire is executing, using said GPS to automatically provide said location identifying information as a response… | The complaint alleges the collection of responses from users via a "location-specific questionnaire," but does not specify how GPS data is used as a "response." | ¶10 | col. 14:63-65 |

Identified Points of Contention
- Scope Questions: A central dispute may arise over whether the Arby's mobile ordering interface constitutes a "questionnaire" with "branching logic" as contemplated by the patent. The patent's examples focus on survey-style data collection (e.g., for a "mystery shopper"), which raises the question of whether a standard e-commerce flow falls within the claim's scope.
- Technical Questions: The complaint does not specify how the accused app uses GPS data. A key factual question will be whether the app uses location data "as a response" to a question, as required by the claim, or whether it uses location services merely for contextual purposes, such as identifying nearby restaurants, which may not meet the claim limitation. Further, the complaint lacks allegations to support the final limitation of making the responses available via the Internet.
V. Key Claim Terms for Construction
The Term: "questionnaire"
Context and Importance: This term is foundational to the infringement theory. Its construction will determine whether a mobile commerce application, like the accused Arby's app, can be considered an infringing instrumentality. Practitioners may focus on this term because the patent's detailed description emphasizes survey-like or inspection-like data gathering tasks.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent states that the terms "program" and "form" are used interchangeably with "questionnaire" (’748 Patent, col. 8:36-39), which could support an interpretation that includes any structured data input application.
- Evidence for a Narrower Interpretation: The detailed "mystery shopper" example describes a classic survey with a series of explicit questions and timed observations, suggesting a more limited, non-commercial-transactional meaning (’748 Patent, col. 10:37-11:27).
The Term: "using said GPS to automatically provide said location identifying information as a response"
Context and Importance: The infringement analysis depends on whether the accused app performs this specific function. The term links the action (using GPS) to a specific purpose (providing a "response"). This distinguishes it from general background use of location services.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language does not specify the format of the "response," potentially allowing for GPS data to be automatically populated into any data field transmitted back to the server.
- Evidence for a Narrower Interpretation: The claim structure places this step within the "executing said transferred questionnaire" context, suggesting the GPS data serves as the answer to a specific prompt or question within that questionnaire, rather than as ambient data collected for another purpose. The patent also discusses a question that "requests location identifying information," and this limitation appears to describe how that request is fulfilled (’748 Patent, col. 14:53-54, 14:63-65).
VI. Other Allegations
Indirect Infringement
- The complaint alleges inducement by asserting that Arby's directs customers to use the app in an infringing manner through advertising, promotion, and user guides (Compl. ¶15). It also alleges contributory infringement, claiming the app has "special features" that are "specially designed to be used in an infringing way" and lack substantial non-infringing uses (Compl. ¶16).
Willful Infringement
- Willfulness is alleged based on Defendant’s knowledge of the patent "at least as of the date when it was notified of the filing of this action" (Compl. ¶17). The complaint also pleads willful blindness, alleging on information and belief that Defendant has a "policy or practice of not reviewing the patents of others" (Compl. ¶18).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "questionnaire", which is described in the patent in the context of survey-like data collection, be construed broadly enough to read on a modern mobile e-commerce ordering application?
- A key evidentiary question will be one of functional operation: does the Arby's Mobile App use GPS data to automatically provide a "response" to a specific prompt within its workflow, as required by the claim, or does it use location services for a different function, such as finding nearby stores, that may fall outside the claim's scope?
- A central legal and strategic question will be the impact of the prosecution and post-grant history: given that asserted Claim 7 has survived multiple IPR challenges while numerous other claims were cancelled, the patent enters litigation with a strengthened presumption of validity, which may significantly influence case strategy and settlement posture.
