The complaint cites a ruling in a separate case, Tiare Technology, Inc. v. Whataburger Restaurants LLC, where the same court allegedly denied challenges to the eligibility of the asserted patents.

Case Timeline

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

U.S. Patent No. 8,682,729 - "Patron Service System and Method," Issued March 25, 2014

The Invention Explained

• Problem Addressed: The complaint asserts that conventional ordering systems prior to the invention, such as centrally-located kiosks or staff-operated handheld terminals, created significant drawbacks. These systems either required patrons to leave their location to place an order or did not allow patrons to place an order themselves, and they lacked the ability to track a patron's location to facilitate delivery of the order (Compl. ¶¶33-35, citing ’729 Patent, col. 2:21-60).
• The Patented Solution: The invention is described as a reimagined mobile-ordering architecture that uses a "portable patron unit" (e.g., a smartphone) running a "venue-specific application." The system solves the prior art problems by allowing the patron to place an order directly from their device and by tracking the location of that device to facilitate order fulfillment (Compl. ¶36). This integration of mobile ordering with location tracking is presented as the core technical improvement over prior systems (Compl. ¶37).
• Technical Importance: The complaint alleges that at the time of invention in the early 2000s, this approach was an unconventional technical solution, as mobile computing devices and location-tracking technologies like GPS and Wi-Fi were still in their nascent stages (Compl. ¶37).

Key Claims at a Glance

• The complaint asserts infringement of independent claim 1 (’729 Patent, col. 26:12-32; Compl. ¶56).
• The essential elements of claim 1 include:
  • providing at least one patron with a wireless patron unit that includes at least one venue specific application program;
  • connecting the wireless patron unit to a server;
  • entering a patron order for at least one item or service provided by the venue into the wireless patron unit;
  • determining a current location of the wireless patron unit;
  • updating a status of the patron order, and the current location of the wireless patron unit when the patron moves to a different location, on the wireless patron unit; and
  • displaying the patron order on a display of the wireless patron unit.

U.S. Patent No. 10,157,414 - "Patron Service System and Method," Issued December 18, 2018

The Invention Explained

• Problem Addressed: The patent's background section describes the service inefficiencies in large venues like resorts. Patrons faced difficulties finding staff to place orders, leading to delays, while staff faced challenges in locating patrons for delivery, especially if the patron moved after placing an order. Existing solutions like kiosks or staff-operated POS devices were described as having limited effectiveness (’414 Patent, col. 1:42-2:57).
• The Patented Solution: The patent discloses a system comprising wireless "portable patron units" and "portable staff units" that communicate with a central server (’414 Patent, Fig. 1). The system allows a patron to order directly from their device, which then communicates the order and the device’s location to the server. The server can then route this information to staff units to enable efficient delivery to the patron's location (’414 Patent, col. 3:1-17; col. 4:18-31).
• Technical Importance: The invention provided a comprehensive, integrated wireless system designed to improve service delivery and patron convenience in complex, expansive environments like resorts, stadiums, or beaches (’414 Patent, col. 4:1-12).

Key Claims at a Glance

• The complaint asserts infringement of independent claim 8 (’414 Patent, col. 26:7-32; Compl. ¶75).
• The essential elements of this computer-implemented method claim include:
  • providing, over a wireless communications channel, a venue-specific application to a mobile computing device;
  • communicating with the mobile device to authenticate a user based on a security protocol;
  • receiving location information from the mobile device;
  • determining a location of the mobile device at a first time based on the location information;
  • mapping the location to a region associated with a venue;
  • receiving order information from the mobile device;
  • receiving updated location information from the mobile device; and
  • determining an updated location of the mobile device at a second time based on the updated location information.

Multi-Patent Capsule

• Patent Identification: U.S. Patent No. 11,195,224, "Patron Service System and Method," Issued December 7, 2021 (Compl. ¶27).
• Technology Synopsis: A continuation of the same patent family, the ’224 Patent claims a system for locating multiple electronic devices. The system provides a venue-specific application to the devices, receives location signals from them at a first and second time to determine updated locations, and, upon receiving an order from one device, sends data indicating its updated location to a computing system associated with the venue for display in a graphical user interface (Compl. ¶¶102-113).
• Asserted Claims: The complaint asserts infringement of independent claim 10 (Compl. ¶95).
• Accused Features: The complaint accuses Defendant’s system of providing the Taco Bell mobile application, receiving initial and updated location information from users' devices, receiving order information, and sending updated location data to a venue-associated computing system to facilitate order pickup (Compl. ¶¶102-113).

III. The Accused Instrumentality

Product Identification

• Defendant’s mobile application (the "Accused Products") (Compl. ¶9, n.1).

Functionality and Market Context

• The accused instrumentality is a mobile software application that allows users to place food and beverage orders from Defendant's stores for pickup (Compl. ¶18). The complaint characterizes it as a "venue-specific application" where the functionality is associated with Defendant's store chain (Compl. ¶51). A key accused feature is the application's use of the mobile device's location services to find nearby stores and to track the user's arrival for order pickup via an "Order Tracker" function (Compl. ¶52). The complaint provides a screenshot showing the application's map-based store selection interface (Compl. p. 14). Plaintiff alleges that the application has been used to complete a significant number of mobile orders, generating substantial revenue for the Defendant (Compl. ¶54).

IV. Analysis of Infringement Allegations

8,682,729 Patent Infringement Allegations

10,157,414 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question may be whether the term "a venue," as described in the patents with a focus on single, contained locations like resorts or stadiums, can be construed to read on a distributed network of individual quick-service restaurant locations. The complaint alleges the application is configured for a "venue (e.g., a Defendant store)" but also that it "may apply to more than one location" (Compl. ¶51).
  • Technical Questions: The asserted claims in the ’729 and ’414 Patents require determining an initial location and then an "updated location" at a second time. A potential point of contention may be whether the accused application's functionality for finding a nearby store and then confirming arrival for pickup meets the functional requirements of the claims, which originated in the context of tracking a patron moving around a large area (e.g., a pool or beach) for delivery.

V. Key Claim Terms for Construction

• The Term: "venue-specific application" (appears in asserted claims of both the ’729 and ’414 Patents)

  • Context and Importance: This term is critical, as the complaint emphasizes that its inclusion was instrumental in overcoming patent-eligibility rejections during prosecution (Compl. ¶¶47-48). Its construction will likely be central to both infringement and validity analyses. Practitioners may focus on this term because its scope could determine whether an application for a national chain of stores falls within the claims.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification states that the system may be used in "various other venues including, but not limited to, stadiums, arenas, retail locations..." (’414 Patent, col. 4:5-8), which could support an argument that "venue" is a broad term covering any individual commercial establishment, including one store in a chain.
    • Evidence for a Narrower Interpretation: The patent's background and detailed description are heavily focused on the context of a single, contiguous hospitality property like a "resort," "hotel," or "cruise line" where patrons and staff move within a defined area (’414 Patent, col. 1:22-41; Abstract). This may support an argument that "venue-specific" implies specificity to a single, self-contained location rather than a brand or chain of locations.

• The Term: "updating... the current location of the wireless patron unit when the patron moves to a different location" (’729 Patent, Claim 1)

  • Context and Importance: This limitation defines a core technical function of the claimed method. The dispute may center on the nature of the "updating" and what constitutes moving to a "different location" in the context of the accused system.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language does not explicitly require continuous or real-time tracking. Plaintiff may argue that any determination of location that is subsequent to an initial one (e.g., a first check to find a store, and a second check upon arrival) satisfies the "updating" requirement.
    • Evidence for a Narrower Interpretation: The specification describes the problem of locating a patron who "has moved and is not seated where the original order was taken" within a resort environment (’414 Patent, col. 2:3-6). This context suggests a function of tracking a user's movement within a venue to enable delivery, which may be argued as technically distinct from merely confirming a user's arrival at a predefined, fixed address.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for all three asserted patents. The factual basis is Defendant's alleged act of supplying the accused mobile application to consumers through app stores and providing instructions that encourage users to operate the application in an infringing manner (Compl. ¶¶60, 79, 99).
• Willful Infringement: Plaintiff alleges willful infringement for all three patents, asserting that Defendant "knew or should have known" of the patents but was "willfully blind." The complaint establishes a basis for post-suit willfulness by stating Defendant has had actual knowledge of the patents and its infringement since at least the filing of the complaint (Compl. ¶¶61, 80, 100).

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

• A core issue will be one of definitional scope: can the term "venue," which is rooted in the patent's disclosure of a single, contiguous hospitality property like a resort, be construed to cover one or more individual, geographically dispersed fast-food restaurants within a national chain?
• A key evidentiary question will be one of functional mismatch: does the accused application's location-tracking feature—which the complaint alleges is used to find nearby stores and facilitate order pickup—perform the same specific technical function of "updating" a mobile patron's location for on-site delivery as contemplated by the patents?
• A third question, stemming from the procedural history cited in the complaint, will be the preclusive effect of prior court rulings: to what extent will the court be influenced by the prior denial of eligibility challenges against these same patents in the Whataburger case, and how will that impact any potential validity challenges raised by the Defendant?
