Case Timeline

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

• 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 the technical landscape of the early 2000s, where handheld computing devices suffered from significant problems. These included software incompatibility across different hardware platforms, requiring costly custom programs for each device type, and the inability to easily share data between them (Compl. ¶23; ’748 Patent, col. 1:49-2:12). Data collection often relied on paper forms, which introduced delays and errors during manual data entry, while early wireless networks were unreliable and offered limited bandwidth (Compl. ¶23; ’748 Patent, col. 1:26-32, col. 3:64-4:1).
• The Patented Solution: The invention claims to solve these issues with a system that uses "device-independent...tokens" to represent a "questionnaire" ('748 Patent, col. 13:51-54). This tokenized approach allows a single questionnaire to be executed on various remote devices without needing to be recompiled for each one (Compl. ¶26; ’748 Patent, col. 5:21-32). The system is designed for "loosely networked" environments, meaning it can store data locally when a network is unavailable and transmit it later when a connection is restored (’748 Patent, col. 5:4-12). A key feature is the use of an integrated GPS to automatically capture location data and customize the questionnaire based on that location (’748 Patent, col. 5:33-48, Fig. 1).
• Technical Importance: This approach aimed to streamline the deployment of data-gathering applications on heterogeneous mobile devices, making data collection in the field more efficient, timely, and accurate compared to prior paper-based or device-specific software solutions (Compl. ¶¶24-26; ’748 Patent, col. 2:41-54).

Key Claims at a Glance

• The complaint asserts independent Claim 7 (’748 Patent, Compl. ¶12).
• The essential elements of Claim 7 are:
  • Designing a questionnaire customized for a particular location with branching logic.
  • The questionnaire must include at least one question requesting 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 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.

III. The Accused Instrumentality

Product Identification

• The "Panera Mobile App" operating "in conjunction with Panera servers" (Compl. ¶11).

Functionality and Market Context

• The complaint alleges that the accused instrumentality comprises a system that enables Panera to "create and execute a location-specific questionnaire to collect responses from users" (Compl. ¶11). This system is used by customers to place orders for Panera restaurants (Compl. ¶6). The complaint does not provide further technical detail about the app's architecture or specific operational methods, focusing instead on its alleged high-level function.

No probative visual evidence provided in complaint.

’748 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: A primary question may be whether the process of selecting menu items and placing an order in an e-commerce application constitutes a "questionnaire" for collecting "survey data" as those terms are used in the patent. The patent's specification provides examples centered on "mystery shoppers" performing inspections, which may suggest a different context and purpose than a commercial transaction (’748 Patent, col. 9:40-10:55).
• Technical Questions: The complaint alleges the system is "location-specific," but provides no facts regarding how the Panera app uses GPS. A key technical question will be whether the app's functionality meets the specific limitation of "using said GPS to automatically provide said location identifying information as a response to said executing questionnaire" (emphasis added), or if it uses location services for a different purpose, such as merely populating a list of nearby stores.

V. Key Claim Terms for Construction

• The Term: "questionnaire"

  • Context and Importance: The applicability of the patent to the accused app hinges on whether a food ordering interface is a "questionnaire." Practitioners may focus on this term because Defendant will likely argue that its e-commerce platform is fundamentally different from the data-gathering and inspection forms described in the patent's examples.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent states that the terms "program" and "form" are used "interchangeably with questionnaire" (’748 Patent, col. 8:37-39), and describes the creation of a "series of questions or statements, each of which calls for a response" (’748 Patent, col. 8:26-29), which could arguably describe an order form.
    • Evidence for a Narrower Interpretation: The most detailed embodiment describes a "mystery shopper" at a fast-food restaurant collecting data on "service time, cleanliness, friendliness of the employees, etc." (’748 Patent, col. 9:35-39). This context may support a narrower construction limited to forms for inspection, survey, or explicit data gathering, rather than commercial transactions.

• The Term: "loosely networked"

  • Context and Importance: This term defines the technological environment of the invention. Its construction will be critical for determining whether the patent, which was filed in the era of early, unreliable mobile data, applies to modern, persistent cellular and Wi-Fi networks.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent defines the term as a system "tolerant of intermittent network connections" where, if a connection is unavailable, "information is temporarily stored in the device and later transmitted when the connection is restored" (’748 Patent, col. 5:4-12). This could be interpreted to cover any modern mobile app that caches data for offline functionality.
    • Evidence for a Narrower Interpretation: The patent's background extensively discusses the specific limitations of early 2000s wireless technology, such as CDPD interfaces with "limited bandwidth, e.g. 19.2 kbaud" (’748 Patent, col. 3:45-53). This may support an argument that the term is tied to that specific technological context of highly constrained and unreliable networks, not modern broadband mobile networks.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement, stating Defendant provides instructions and encourages customers to use the Panera Mobile App in an infringing manner (Compl. ¶16). It also pleads contributory infringement, alleging the accused products contain special features with no substantial non-infringing use (Compl. ¶17).
• Willful Infringement: Willfulness is alleged based on Defendant's knowledge of the patent from at least the filing of the lawsuit (Compl. ¶18). The complaint also alleges willful blindness, claiming 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

• A core issue will be one of definitional scope: can the term "questionnaire," rooted in patent examples of structured data-gathering for inspections, be construed to cover the transactional user flow of a modern e-commerce application for ordering food?
• A key evidentiary question will be one of technical mechanism: what proof exists that the accused app performs the specific function of "using said GPS to automatically provide said location identifying information as a response" as required by Claim 7, or does it use location services in a way that falls outside this claimed functionality?
• A central legal and strategic question will be the impact of the patent's prosecution history: how will the court weigh the fact that asserted Claim 7 was previously confirmed as patentable in an IPR proceeding against the defendant's anticipated non-infringement arguments based on claim construction and the operational realities of its mobile app?
