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's background section describes a fragmented early-2000s mobile computing landscape where software applications were incompatible across different handheld devices due to varying hardware and operating systems (Compl. ¶22; ’948 Patent, col. 1:49-2:2). This made developing, deploying, and updating data collection applications for field use inefficient and costly, particularly given the challenges of intermittent network connectivity and limited bandwidth (Compl. ¶22; ’948 Patent, col. 3:7-10, 3:64-4:1).
• The Patented Solution: The invention proposes a system to overcome these issues by using "device indifferent tokens" to represent a questionnaire's logic and questions, allowing a single designed questionnaire to run on diverse devices without custom compilation for each one (Compl. ¶25; ’948 Patent, col. 5:21-32). The system operates on a "loosely networked" basis, enabling it to function with unreliable connections by storing data locally and transmitting it when a connection becomes available (Compl. ¶26; ’948 Patent, col. 5:4-13). It also specifically teaches using an integrated GPS unit to automate the collection of location data as part of the questionnaire process (Compl. ¶27; ’948 Patent, col. 10:55-65).
• Technical Importance: The described approach aimed to create a unified platform for mobile data collection, reducing development costs and enabling near real-time data access from a variety of remote devices (Compl. ¶25; ’948 Patent, col. 2:41-54).

Key Claims at a Glance

• The complaint asserts independent Claim 7 (Compl. ¶11).
• The essential elements of Claim 7 are:
  • Designing a questionnaire customized for a particular location with branching logic and a request for location information.
  • Automatically transferring the questionnaire to a "loosely networked computer" with 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 information "as a response" to the questionnaire.
  • Automatically transferring collected responses in "real time" to a central computer via the loose network.
  • Making the transferred responses available via the Internet.
• The complaint's prayer for relief references "one or more claims," potentially reserving the right to assert others later (Compl. p. 11, ¶a).

III. The Accused Instrumentality

Product Identification

• The "Chipotle mobile app" operating "in conjunction with Chipotle servers" (Compl. ¶10).

Functionality and Market Context

• The complaint alleges the system functions to "create and execute a location-specific questionnaire to collect responses from users" (Compl. ¶10). This functionality is described in the context of directing customers to specific Chipotle restaurant locations and receiving food orders from them through the mobile app (Compl. ¶5). The complaint does not provide further technical detail on the app's architecture or specific user interface flows. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint provides a high-level infringement theory without a detailed element-by-element mapping. The following chart summarizes the allegations for the sole asserted claim based on the theory articulated in the complaint.

'748 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A primary issue may be whether a mobile food-ordering interface constitutes a "questionnaire" for collecting "survey data" as those terms are used in the patent. The defense may argue that the patent's context (e.g., mystery shopping, medical data collection) implies a different purpose than a commercial sales transaction (col. 10:37-43, 11:43-48).
  • Technical Questions: The infringement analysis may turn on whether the accused app uses GPS data as a response to a query within the questionnaire, as required by element (d). A key question is whether the app simply uses location to select the correct store menu (a configuration step) or if the location data itself is collected and transmitted as a substantive answer within the "questionnaire."

V. Key Claim Terms for Construction

• The Term: "questionnaire"

  • Context and Importance: The applicability of the entire claim hinges on this term. Practitioners may focus on this term because its construction will determine whether the patent can read on a broad class of mobile commerce applications or is limited to more explicit data-gathering and survey tools.
  • Intrinsic Evidence for a Broader Interpretation: The specification suggests the term is not limited, stating a questionnaire is a "series of questions or statements, each of which calls for a response" and using it interchangeably with "program" and "form" (col. 8:26-28, 8:39-40).
  • Intrinsic Evidence for a Narrower Interpretation: The claim preamble refers to "collecting survey data," and the detailed examples focus on mystery shopping and medical data collection, suggesting a primary focus on information gathering rather than commercial transactions (col. 10:37-43, 11:43-48).

• The Term: "using said GPS to automatically provide said location identifying information as a response"

  • Context and Importance: This term is critical for determining infringement of claim element (d). The dispute will likely center on the precise role of GPS data in the accused system's workflow.
  • Intrinsic Evidence for a Broader Interpretation: A plaintiff may argue that any automatic provision of location data that is essential for the completion of the questionnaire's task (e.g., placing an order at the correct store) functionally serves "as a response."
  • Intrinsic Evidence for a Narrower Interpretation: A defendant may argue that the claim language requires the GPS coordinates themselves to be the substance of a "response" that is collected and stored, not merely a transient input used to configure the application's state (e.g., by selecting a store).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating Defendant directs customers to use the app in an infringing manner through instructions and promotion (Compl. ¶15). It also alleges contributory infringement, claiming the app has special features designed for infringement with no substantial non-infringing uses (Compl. ¶16).
• Willful Infringement: Willfulness is alleged based on knowledge of the patent from the filing of the lawsuit (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

• A core issue will be one of definitional scope: can the term "questionnaire" for collecting "survey data," which the patent illustrates in the context of field inspections and data gathering, be construed to cover a commercial mobile food-ordering system?
• A key evidentiary question will be one of technical function: does the accused application’s use of GPS data constitute providing location information as a response to the questionnaire, as required by Claim 7, or is the location data used merely as a parameter to configure the application, a potentially non-infringing alternative?
• Given that Claim 7 has survived an inter partes review, which strengthens its presumption of validity, the case will likely focus heavily on these nuanced questions of claim construction and infringement, rather than on challenges based on prior art.
