I. Executive Summary and Procedural Information

  • Parties & Counsel:
  • Case Identification: 5:24-cv-00174, E.D. Tex., Filed 11/25/2024
  • 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 there, and maintains a "regular and established place of business" in the form of a retail store in Texarkana, Texas.
  • Core Dispute: Plaintiff alleges that Defendant’s Best Buy Mobile App, in conjunction with its servers, infringes a patent related to methods for creating, distributing, and executing location-aware, cross-platform data collection applications.
  • Technical Context: The technology addresses challenges in developing software for the fragmented market of early-2000s handheld computing devices, aiming to provide a single, adaptable framework for data gathering that is independent of specific hardware or operating systems and resilient to intermittent network connections.
  • Key Procedural History: The asserted claim of the patent-in-suit (Claim 7) has previously survived an Inter Partes Review (IPR) proceeding (IPR2019-00610), which found the claim patentable. The complaint also cites a prior case ([Fall Line Patents, LLC](https://ai-lab.exparte.com/party/fall-line-patents-llc) v. Zoe's Kitchen, Inc.) where the patent survived a motion to dismiss on patent eligibility grounds and was later subject to a summary judgment order finding it valid under 35 U.S.C. § 101.

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,454,748 - System and Method for Data Management

  • Patent Identification: 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 creating software for remote data collection was difficult and costly. Developers had to create custom, device-specific programs for different handheld computers, which had varying processors, operating systems, and limited, unreliable network access (’748 Patent, col. 1:49-2:12). Making even a single change required recompiling and reinstalling the entire program on each type of device (’748 Patent, col. 3:7-10).
  • The Patented Solution: The invention proposes a system where a data-gathering application, framed as a "questionnaire," is created on a central server and converted into a set of device-independent "tokens" (’748 Patent, col. 4:56-5:2). These tokens, representing questions and logic, are sent to remote handheld devices. The devices run a specialized operating system or engine that can interpret and execute these tokens, regardless of the native hardware (’748 Patent, col. 5:14-24). This architecture allows for a single questionnaire to run on multiple device types and for small, incremental updates to be pushed to the field without reinstalling the entire application, conserving limited bandwidth (’748 Patent, col. 5:26-32). The system is designed to be "loosely networked," meaning it stores data locally when a network connection is unavailable and transmits it when the connection is restored (’748 Patent, col. 5:3-13).
  • Technical Importance: This approach aimed to decouple application logic from underlying hardware, a significant step toward creating universal, easily updatable applications for a fragmented mobile device market, particularly for field service and data collection industries (’748 Patent, col. 2:41-48).

Key Claims at a Glance

  • The complaint asserts independent Claim 7.
  • The essential elements of Claim 7 are:
    • Designing a questionnaire customized for a particular location, with branching logic, on a first computer.
    • The questionnaire must request location-identifying information.
    • Automatically transferring the questionnaire to a "loosely networked computer" that has an integrated GPS.
    • Executing the questionnaire on the remote computer when it is at the specified location to collect user responses.
    • While executing, using the GPS to automatically provide location information as a response to the questionnaire.
    • Automatically transferring collected responses in "real time" over the "loose network" to a central computer.
    • 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 "Best Buy mobile app" used "in conjunction with Best Buy servers" (Compl. ¶11).

Functionality and Market Context

  • The complaint alleges that the accused instrumentality operates to "create and execute a location-specific questionnaire to collect responses from users" (Compl. ¶11). The complaint does not provide specific details on the technical operation of the app's features, such as how it uses location data or communicates with servers. It frames the app's use in the context of directing customers to, and receiving orders for, Best Buy's physical store locations within the judicial district (Compl. ¶6).

IV. Analysis of Infringement Allegations

The complaint provides a high-level infringement theory without a detailed claim chart or reference to specific product features beyond a general description. The following table summarizes the allegations based on the limited information provided. No probative visual evidence provided in complaint.

  • ’748 Patent Infringement Allegations
Claim Element (from Independent Claim 7) Alleged Infringing Functionality Complaint Citation Patent Citation
(a) designing a questionnaire including at least one question said questionnaire customized for a particular location having branching logic on a first computer platform... Best Buy's servers allegedly create a "location-specific questionnaire." ¶11 col. 8:41-49
(b) automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto; The questionnaire is allegedly transferred to the Best Buy mobile app, which runs on a GPS-enabled mobile device. ¶11 col. 5:3-13

(d) while said transferred questionnaire is executing, using said GPS to automatically provide said location identifying information as a response to said executing questionnaire; The system is alleged to be "location-specific," implying the use of GPS to provide location information as part of the questionnaire's function. ¶11 col. 10:55-65
(e) automatically transferring via the loose network any responses so collected in real time to a central computer; and, The mobile app allegedly transfers collected responses from the user to Best Buy's servers. ¶11 col. 5:7-13
(f) making available via the Internet any responses transferred to said central computer in step (e). The system operates via the Best Buy mobile app and servers, which are connected to the Internet. ¶11 col. 10:10-14
  • Identified Points of Contention:
    • Scope Questions: The core of the dispute may turn on whether the functionality of the Best Buy app (e.g., presenting location-based store information, promotions, or order forms) can be properly characterized as a "questionnaire" as that term is used in the patent. A question for the court will be whether presenting commercial information qualifies as a "survey" or data collection "questionnaire."
    • Technical Questions: A key technical question is whether the app's use of location services meets the specific limitation of "using said GPS to automatically provide said location identifying information as a response to said executing questionnaire." The complaint does not allege facts to distinguish between general location-aware functionality and the claim's requirement that the GPS data itself constitutes a specific "response." Further, it is unclear what evidence supports the allegation that the app and server architecture meets the patent's definition of a "loose network," which implies specific behavior for handling intermittent connectivity.

V. Key Claim Terms for Construction

  • The Term: "questionnaire customized for a particular location"

    • Context and Importance: This term is central to the infringement analysis. The definition will determine whether the accused app's features, which may include location-based store finders or promotional offers, fall within the scope of the claim. Practitioners may focus on this term because its construction will likely be dispositive of whether the accused app performs the claimed method at all.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent specification describes the questionnaire in terms of a "series of questions or statements, each of which calls for a response," and notes that the terms "program" and "form" are used interchangeably with "questionnaire" (’748 Patent, col. 8:26-37). This could support a broader reading that includes any interactive, form-based data entry.
      • Evidence for a Narrower Interpretation: The examples in the specification focus on structured data gathering tasks like "mystery shopping" for a restaurant, which involve a sequence of specific observational questions (’748 Patent, col. 10:40-11:28). This context may support a narrower construction limited to survey-like or inspection-like activities, rather than general e-commerce interactions.

  • The Term: "loosely networked computer"

    • Context and Importance: Claim 7 requires the method to be performed on a "loosely networked computer." The patent provides an explicit definition for this term, so the dispute will be a factual one: does the Best Buy app, in its communication with servers, operate in the manner described by the patent's definition?
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The definition is functional, covering any system "tolerant of intermittent network connections" where "network transmissions occur normally, in real time" if a connection is available (’748 Patent, col. 5:7-10). Most modern mobile apps are designed to function over cellular or Wi-Fi networks, which are inherently intermittent.
      • Evidence for a Narrower Interpretation: The definition requires that if a connection is unavailable, "the information is temporarily stored in the device and later transmitted when the connection is restored" (’748 Patent, col. 5:10-12). A defendant may argue that this requires a specific store-and-forward mechanism that its app does not implement, or that its app simply presents an error or fails to function offline, rather than actively storing and later transmitting transactional data as described.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges inducement by asserting that Best Buy advises, directs, and provides instructions to its customers to use the accused app in an infringing manner (Compl. ¶16). It alleges contributory infringement by claiming the app has "special features" that are not "staple articles of commerce suitable for substantial non-infringing use" (Compl. ¶17).
  • Willful Infringement: Willfulness is alleged based on knowledge of the patent "at least as of the date" of the complaint's filing (Compl. ¶18). The complaint also alleges willful blindness, stating on information and belief that Defendant has a "policy or practice of not reviewing the patents of others" (Compl. ¶19).

VII. Analyst’s Conclusion: Key Questions for the Case

The resolution of this case may depend on the court’s determination of the following open questions:

  1. A core issue will be one of definitional scope: Can the features of a modern retail mobile application, such as a store locator or a mobile checkout process, be construed to meet the patent's specific definition of a "questionnaire customized for a particular location" that collects "survey data"?
  2. A key evidentiary question will be one of technical implementation: Does discovery show that the Best Buy app and its server backend operate as a "loosely networked" system as defined by the patent, particularly regarding the specific store-and-forward mechanism for intermittent connectivity?
  3. A central factual question will be one of functional specificity: Does the Best Buy app's use of device GPS meet the precise claim requirement of automatically providing location data as a response within a questionnaire, or does it merely use location services for general content personalization, creating a potential mismatch with the claimed method?
