• Core Dispute: Plaintiff alleges that Defendant’s mobile application and associated server infrastructure infringe a patent related to location-aware data collection on remote devices.
• Technical Context: The technology addresses methods for creating and deploying data collection applications (termed "questionnaires") that can operate across diverse remote computing devices and handle intermittent network connectivity.
• Key Procedural History: The complaint notes that the patent-in-suit, U.S. Patent No. 9,454,748, was previously subject to litigation where a motion to dismiss was denied and a motion for summary judgment of validity under 35 U.S.C. § 101 was granted. Public records also show that the asserted claim in this case, Claim 7, survived an Inter Partes Review (IPR) proceeding (IPR2019-00610), while other claims were cancelled in that and a separate IPR proceeding. The survival of the asserted claim through a PTAB validity challenge is a significant event that may influence subsequent claim construction and validity arguments.

Case Timeline

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

U.S. Patent No. 9,454,748 - “System and Method for Data Management” (issued Sep. 27, 2016)

The Invention Explained

• Problem Addressed: The patent describes a technical landscape of early handheld computers (circa 2002) plagued by software incompatibility across different hardware, making it difficult to deploy a single application on multiple device types without costly custom programming for each ('748 Patent, col. 1:49-2:2). Further problems included unreliable and low-bandwidth network connections for devices in the field, making real-time data transfer difficult and leading to the use of inefficient manual data entry from paper forms ('748 Patent, col. 2:45-54; 3:64-4:17).
• The Patented Solution: The invention proposes a system using "device indifferent tokens" to create a "questionnaire" that can be executed on any remote computer equipped with a compatible operating system overlay, regardless of the underlying hardware ('748 Patent, col. 9:25-32). This system is designed for "loosely networked" environments where it can store data locally when a connection is unavailable and transmit it later, while also using real-time transfer when a connection is present ('748 Patent, col. 5:3-12). The method integrates GPS functionality to automatically capture location information as part of the data collection process ('748 Patent, col. 10:55-65).
• Technical Importance: This approach sought to create a universal, cross-platform framework for field data collection that was resilient to the network and hardware fragmentation challenges of the early mobile computing era ('748 Patent, col. 1:16-24).

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, where at least one question requests location identifying information.
  • Automatically transferring the questionnaire to a "loosely networked computer" that has an "integral" GPS.
  • Executing the questionnaire on the computer when it is at the particular location to collect user responses.
  • While executing, using the GPS to automatically provide location identifying information "as a response" to the questionnaire.
  • Automatically transferring collected responses "in real time" via the "loose network" to a central computer.
  • Making the transferred responses available via the Internet.

III. The Accused Instrumentality

Product Identification

The "Little Caesar's Mobile App" operating on a customer's mobile device, in conjunction with "Little Caesar's servers" (Compl. ¶10).

Functionality and Market Context

The complaint alleges that the accused system functions to "create and execute a location-specific questionnaire to collect responses from users" (Compl. ¶10). The primary function described is enabling customers to use the mobile app to find nearby restaurant locations and place orders for pickup (Compl. ¶5). The complaint does not provide sufficient detail for analysis of the specific technical implementation of the app's ordering process or its server-side architecture.

IV. Analysis of Infringement Allegations

No probative visual evidence provided in complaint.

’748 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A primary issue will be whether a modern mobile e-commerce application for ordering food constitutes a "questionnaire" as contemplated by the patent. The defense may argue that the patent's disclosure, with its focus on structured field data collection for tasks like mystery shopping or medical reports ('748 Patent, col. 10:37-11:21), does not cover a transactional ordering system.
  • Technical Questions: The infringement analysis may turn on whether the accused app performs functions in the specific manner claimed. For example, Claim 7(d) requires using GPS to provide location information "as a response to said executing questionnaire." It raises the question of whether using GPS to find nearby stores is functionally the same as the claimed step, or if there is a technical mismatch. Similarly, the complaint's general allegations may be tested on whether the data transfer to servers meets the "real time" and "loose network" requirements as defined by the patent's specification.

V. Key Claim Terms for Construction

The Term: "questionnaire"

• Context and Importance: This term is foundational to Claim 7. Its construction will determine whether the patent's scope can encompass the accused mobile ordering application. Practitioners may focus on this term because the patent's examples (e.g., mystery shopping, medical data entry) suggest a formal data-gathering instrument, which may be distinguishable from a consumer-facing e-commerce interface.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent does not provide a formal definition, instead describing it as a "series of questions or statements" created via an administrative interface to prompt a user for a response ('748 Patent, col. 8:26-34). Plaintiff may argue this general description covers any guided user input process, including selecting pizza toppings.
  • Evidence for a Narrower Interpretation: The specification repeatedly uses the term in the context of replacing paper forms for field data collection, such as for mystery shoppers or medical service providers ('748 Patent, col. 10:37-11:54). The detailed description of creating a questionnaire involves building branching logic and selecting question types, suggesting a more structured and formal instrument than a typical food ordering flow ('748 Patent, col. 8:40-67).

The Term: "customized for a particular location"

• Context and Importance: This term in Claim 7(a) is central to the location-based aspect of the invention. Its meaning will be critical for determining if the accused app's use of location services meets this limitation.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: Plaintiff could argue that any system which alters its behavior or output based on location is "customized," such as an app that presents a list of the nearest stores based on the user's GPS data.
  • Evidence for a Narrower Interpretation: The claim language "designing a questionnaire...customized for a particular location" ('748 Patent, col. 15:47-50) suggests the content of the questionnaire itself is pre-designed for a specific place, not merely that the system is location-aware in its operation.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement, stating that Defendant directs customers to use the app in an infringing manner through advertising and instructions (Compl. ¶15). It also pleads contributory infringement, alleging the app has special features specifically designed for infringement with no substantial non-infringing use (Compl. ¶16).
• Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the patent from the date of the complaint's filing (Compl. ¶17). The complaint further alleges willful blindness based on a purported "policy or practice of not reviewing the patents of others" (Compl. ¶18).

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

1. A core issue will be one of definitional scope: can the term "questionnaire", rooted in the patent's context of structured, form-based field data collection, be construed to cover the transactional user interface of the accused mobile food-ordering application?
2. A key evidentiary question will be one of functional mapping: does the Little Caesar's app use GPS data "as a response" to a query in the manner required by Claim 7(d), or is there a fundamental mismatch between how the accused system uses location information (e.g., to find stores) and the specific function recited in the claim?
3. A significant procedural factor will be the impact of prior proceedings: how will the arguments, evidence, and claim construction from the Inter Partes Review that upheld Claim 7, and the prior district court litigation that found the patent eligible under § 101, shape the invalidity and infringement arguments in this case?
