• Case Identification: 2:23-cv-00250, E.D. Tex., 05/30/2023
• Venue Allegations: Plaintiff alleges venue is proper in the Eastern District of Texas because Defendant is registered to do business in Texas and operates multiple regular and established places of business (stores) within the District where it offers the accused mobile ordering services to customers.
• Core Dispute: Plaintiff alleges that Defendant’s mobile ordering application infringes three patents related to systems and methods for mobile ordering that incorporate patron location tracking.
• Technical Context: The technology at issue involves using a customer's mobile device to place an order from a specific venue and tracking the device's location to facilitate order fulfillment, a central feature in the modern restaurant and retail industries.
• Key Procedural History: The complaint highlights an extensive prosecution history for the patent family, noting that claims in the two most recent patents were allowed by the USPTO after amendments were made to overcome patent eligibility rejections under 35 U.S.C. § 101. The complaint also references a prior case against a different defendant in the same court where challenges to the eligibility of the asserted patent family were reportedly denied.

Case Timeline

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

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

The Invention Explained

• Problem Addressed: The patent’s background section describes the drawbacks of conventional ordering systems in venues like resorts, such as centrally-located kiosks or staff-operated handheld terminals (’729 Patent, col. 2:21-60). These systems are described as inconvenient for patrons, who might have to leave their location to order, and inefficient for staff, who face challenges in locating mobile patrons for order delivery (’729 Patent, col. 2:1-6).
• The Patented Solution: The invention proposes a method where a patron uses a "wireless patron unit" (e.g., a smartphone) with a venue-specific application to place an order directly (’729 Patent, Abstract). The system connects this unit to a server and determines the unit's current location, updating both the order status and the location as the patron moves, thereby streamlining the order and delivery process (’729 Patent, Abstract; col. 4:18-31).
• Technical Importance: The complaint alleges this approach provided a technical improvement by integrating patron-controlled mobile ordering with real-time location tracking, a departure from fixed kiosk or staff-centric systems (Compl. ¶36).

Key Claims at a Glance

• The complaint asserts independent claim 1 (Compl. ¶56).
• The essential elements of claim 1 include:
  • Providing a patron with a wireless patron unit, either venue-owned or through a downloadable "venue specific application program" for a patron-owned device.
  • Connecting the wireless patron unit to a server.
  • Entering a patron order into the wireless unit.
  • Determining a current location of the wireless patron unit.
  • Updating a status of the order and the current location of the unit when the patron moves to a different location.
  • Displaying the patron order on the unit's display.

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

The Invention Explained

• Problem Addressed: The patent identifies inefficiencies in service delivery at large venues (e.g., resorts, stadiums), where staff face difficulties locating mobile patrons to deliver orders placed via traditional methods like fixed kiosks or staff-operated point-of-sale devices (’414 Patent, col. 1:40-56).
• The Patented Solution: The invention is a computer-implemented method performed by a server system that provides a "venue-specific application" to a mobile device (’414 Patent, Abstract). The system authenticates the user, receives location information from the device at a first time, maps it to a venue region, receives an order, and then receives and determines an updated location at a second time, enabling continuous tracking to facilitate service (’414 Patent, Abstract; col. 26:15-21).
• Technical Importance: The complaint frames this as an unconventional technical solution that enables centralized, real-time location tracking of distributed mobile devices by integrating location-tracking technology directly into the ordering application (Compl. ¶¶ 37-38).

Key Claims at a Glance

• The complaint asserts independent claim 8 (Compl. ¶75).
• The essential elements of claim 8 include:
  • Providing a "venue-specific application" to a mobile computing device over a wireless channel.
  • Communicating with the device to authenticate a user based on a security protocol.
  • Receiving location information from the device.
  • Determining a location of the device at a first time and mapping it to a region associated with a venue.
  • Receiving order information from the device.
  • Receiving updated location information from the device.
  • Determining an updated location of the device at a second time based on the updated information.

U.S. Patent No. 11,195,224 - "Patron Service System and Method"

• Technology Synopsis: This patent describes a system for locating a plurality of mobile electronic devices. A central computing system provides a venue-specific application to the devices, receives location signals from them, and determines their respective locations (’224 Patent, Abstract). When an order is received from a particular device, the system sends data indicating the updated location of that specific device to a computing system at the venue for display in a graphical user interface, allowing staff to pinpoint the ordering customer (’224 Patent, Claim 10).
• Asserted Claims: Independent claim 10 is asserted (Compl. ¶95).
• Accused Features: The complaint accuses Defendant's system of providing its mobile application to a plurality of users, receiving location information from their devices, determining their locations, receiving orders, and tracking the ordering user's location for fulfillment (Compl. ¶¶ 102-112).

III. The Accused Instrumentality

Product Identification

The accused instrumentality is the Chipotle Mexican Grill mobile application and the associated backend mobile ordering system (collectively, the "Accused Products") (Compl. ¶13, n.1).

Functionality and Market Context

• The complaint alleges the application allows a user to locate a nearby Chipotle store, select menu items, place an order, and pick it up (Compl. ¶18). The system is alleged to access the mobile device's location services to determine a current location for finding local stores and to track the user's arrival for pickup (Compl. ¶52). A screenshot in the complaint depicts a "Pickup Status" screen, which shows the order's progress after it has been received by the restaurant (Compl. p. 15).
• The complaint alleges that Defendant’s use of the mobile ordering application has generated significant revenue and that the mobile-ordering market has grown exponentially (Compl. ¶¶ 1, 54).

IV. Analysis of Infringement Allegations

U.S. Patent No. 8,682,729 Infringement Allegations

U.S. Patent No. 10,157,414 Infringement Allegations

Identified Points of Contention

• Scope Questions: The patent specifications for the asserted patents heavily feature examples set in large, multi-zone environments like resorts and stadiums (’414 Patent, col. 1:18-22). A potential question for the court will be whether the term "venue," as used in the claims, can be properly construed to read on a nationwide chain of individual, physically separate quick-service restaurants, as alleged in the complaint.
• Technical Questions: Claim 1 of the ’729 Patent requires updating the "current location of the wireless patron unit when the patron moves to a different location." The complaint alleges the accused system tracks a device as it "approaches the site" (Compl. ¶93). A factual question may arise as to whether the accused system performs continuous or periodic location updates post-order, or if it performs discrete location checks (e.g., one to find a store, and another to confirm arrival) that may not meet the claim limitation as written.

V. Key Claim Terms for Construction

• The Term: "venue-specific application"
• Context and Importance: This term appears in the independent claims of the two most recently issued patents-in-suit (the ’414 and ’224 Patents). According to the complaint, this limitation was added during prosecution to overcome § 101 patent eligibility rejections (Compl. ¶¶ 47-48). The construction of this term will therefore be critical to both the infringement analysis and any renewed validity challenges based on patent eligibility.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The complaint argues the term covers an application that is "specifically configured for a venue (e.g., a Defendant store) but may apply to more than one location (e.g., multiple Defendant stores)" (Compl. ¶51). The patent specification describes the invention's applicability to "various other venues including, but not limited to, stadiums, arenas, retail locations," which could support a reading beyond a single, contiguous resort (’414 Patent, col. 4:3-6).
  • Evidence for a Narrower Interpretation: The specification's detailed examples focus on a patron moving within a single, large venue with multiple distinct service areas, such as a "pool, beach, spa, deck, lounge, or any other areas associated with resort 101" (’414 Patent, col. 4:20-22). This context could support an argument that a "venue-specific application" is one tailored for navigating and ordering from different points of service within a single, cohesive property, rather than a uniform application used across thousands of independent store locations.

VI. Other Allegations

• Indirect Infringement: The complaint alleges active inducement of infringement for all three asserted patents. The theory is that Defendant knowingly encourages infringement by supplying the mobile application to consumers and providing instructions on its use (e.g., through app stores), which allegedly causes users to perform the steps of the patented methods (Compl. ¶¶ 60, 79, 99).
• Willful Infringement: Willfulness is alleged for all three patents. The allegations are based on knowledge of the patents obtained, at the latest, upon the filing and service 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 and validity: can the term "venue-specific application," which was added to the claims to overcome patent eligibility rejections in the context of a resort-style environment, be construed to cover a standardized mobile ordering app used across a national chain of restaurants? If so, does that broad construction once again raise the question of whether the claims are directed to an abstract idea under 35 U.S.C. § 101?
• A key evidentiary question will be one of technical function: what proof will be offered to show that the accused system performs the claimed step of determining an updated location of a user's device as the user "moves to a different location" post-order? The case may turn on whether the system performs the continuous or periodic tracking described in the patents, or whether it performs discrete location checks that fall outside the scope of the claims.
