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's background describes the technical difficulties of creating data collection applications for the diverse and often incompatible handheld computers of the early 2000s (’748 Patent, col. 1:49-2:2). Key problems included the need to create separate software for different hardware and operating systems ([’748 Patent, col. 3:1-7](https://ex:cit:11)), the challenges of transferring data between incompatible devices ([’748 Patent, col. 2:3-12](https://ex:cit:9)), and the unreliability of network connections in the field ([’748 Patent, col. 3:64-4:1](https://ex:cit:12)).
  • The Patented Solution: The patent proposes a system where data collection "questionnaires" are created and then "tokenized" into a device-independent format ([’748 Patent, col. 2:13-26](https://ex:cit:8)). These tokens can be executed by any remote device running a compatible runtime package, bypassing the need to recompile the entire application for each different device ([’748 Patent, col. 4:66-5:2](https://ex:cit:13)). The system is designed to be "loosely networked," meaning it can store data locally if a network connection is unavailable and transmit it later when the connection is restored ([’748 Patent, col. 5:7-12](https://ex:cit:16)). The invention also contemplates using a device's integrated GPS to automatically capture location data ([’748 Patent, col. 5:45-48](https://ex:cit:15)).
  • Technical Importance: This architecture aimed to simplify and reduce the cost of developing and deploying mobile data collection applications across a fragmented hardware market by abstracting away the underlying device specifics ([’748 Patent, col. 2:57-64](https://ex:cit:10)).

Key Claims at a Glance

  • The complaint asserts independent Claim 7 of the ’748 Patent ([Compl. ¶11](https://ex:cit:2)).
  • The essential elements of Claim 7 are:
    • A method for collecting survey data and making responses available online, comprising:
    • Designing a questionnaire customized for a particular location with branching logic on a first computer, where a question requests location identifying information.
    • Automatically transferring the questionnaire to a "loosely networked computer" with an integrated GPS.
    • Executing the questionnaire on the remote computer when it is at the specified location to collect user responses.
    • Using the GPS to automatically provide the location information as a response during execution.
    • 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 does not state an intention to assert any other claims.

III. The Accused Instrumentality

Product Identification

  • The "Lululemon Mobile App," operating "in conjunction with Lululemon servers" ([Compl. ¶10](https://ex:cit:1)).

Functionality and Market Context

  • The complaint alleges that the accused system is used to "create and execute a location-specific questionnaire to collect responses from users" ([Compl. ¶10](https://ex:cit:1)). It also alleges that Lululemon uses the mobile app to direct customers to its physical store locations within the judicial district ([Compl. ¶5](https://ex:cit:6)). The complaint does not provide specific technical details about the app's functionality, such as the nature of the "questionnaire" or the specific data being collected. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges infringement of Claim 7. The following table summarizes the allegations, which are stated at a high level.

’748 Patent Infringement Allegations

Claim Element (from Independent Claim 7) Alleged Infringing Functionality Complaint Citation Patent Citation
(a) designing a questionnaire including at least one question said questionnaire customized for a particular location having branching logic...wherein at least one...questions requests location identifying information; Defendant's app and servers allegedly "create and execute a location-specific questionnaire to collect responses from users." ¶10 col. 15:7-14
(b) automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto; Defendant allegedly "provided, supplied, distributed, sold, and/or offered Lululemon mobile apps," which are downloaded to users' mobile devices (the loosely networked computers). ¶10 col. 15:15-18
(c) when said loosely networked computer is at said particular location, executing said transferred questionnaire on said loosely networked computer, thereby collecting responses from the user; The system allegedly executes a "location-specific questionnaire" on the user's mobile device. ¶10 col. 15:19-23
(d) while said transferred questionnaire is executing, using said GPS to automatically provide said location identifying information as a response to said executing questionnaire; The complaint alleges a "location-specific questionnaire," which implies the use of location data, but does not detail how GPS is used to provide a response automatically. ¶10 col. 15:24-27
(e) automatically transferring via the loose network any responses so collected in real time to a central computer; and, The app allegedly operates "in conjunction with Lululemon servers" to "collect responses from users," implying a transfer of data from the user's device to a server. ¶10 col. 15:28-31
(f) making available via the Internet any responses transferred to said central computer in step (e). The complaint does not provide sufficient detail for analysis of this element. col. 15:32-34
  • Identified Points of Contention:
    • Technical Questions: A central question will be evidentiary. What evidence does the complaint provide that the Lululemon app executes what can be legally defined as a "questionnaire" with "branching logic"? Furthermore, does the app use the device's GPS to automatically provide location information as a response to a specific question, as the claim requires, or does it use location services for other purposes not covered by the claim? The complaint lacks factual support for the final step of "making available via the Internet" the collected responses.
    • Scope Questions: A likely point of dispute is the definition of "questionnaire." The defense may argue that modern location-based marketing notifications or simple user interface prompts within the Lululemon app do not constitute a "questionnaire" as described in the patent, which provides examples of complex, multi-step data-entry forms ([’748 Patent, col. 10:40-11:21](https://ex:cit:18)).

V. Key Claim Terms for Construction

  • The Term: "questionnaire"

    • Context and Importance: This term is the core of the claimed method. Its construction will be critical in determining whether the functionality of the Lululemon app falls within the scope of the claim. Practitioners may focus on this term because the accused functionality might be characterized by the defense as simple user prompts rather than a formal "questionnaire."
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent specification suggests a broad meaning, using "questionnaire" interchangeably with "program" and "form" ([’748 Patent, col. 8:39-41](https://ex:cit:17)) and stating it can be created by a non-programmer ([’748 Patent, col. 5:35-38](https://ex:cit:14)), which may support its application to a wide range of user-interactive features.
      • Evidence for a Narrower Interpretation: The detailed "mystery shopper" example describes a complex, multi-stage data collection process with multiple timers and a series of specific, ordered questions ([’748 Patent, col. 10:40-11:21](https://ex:cit:18)). This embodiment could be used to argue for a narrower definition requiring a more structured, formal, and multi-step data gathering process.

  • The Term: "customized for a particular location"

    • Context and Importance: This phrase links the "questionnaire" to a geographic place. The dispute will likely center on the degree and nature of "customization" required. Practitioners may focus on this term to determine if a generally available questionnaire that simply asks about a location meets the limitation, or if the questionnaire itself must be unique to that location.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The claim language itself does not specify that the customization must happen dynamically. It could be argued that a questionnaire "designed" for a location (e.g., about a specific store) and then sent to a device meets the requirement, even if the content is static.
      • Evidence for a Narrower Interpretation: The claim requires executing the questionnaire when the device is at the location ([’748 Patent, col. 15:19-21](https://ex:cit:19)). This temporal and geographical link could support an interpretation that the content or behavior of the questionnaire must be specifically tailored or triggered by the device's presence at that location, rather than being a pre-set form that is merely executed there.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges inducement of infringement, stating that Defendant took active steps with the specific intent to cause its customers to infringe by "advising or directing" them and distributing "instructions that guide users" ([Compl. ¶15](https://ex:cit:3)).
  • Willful Infringement: Willfulness is alleged on the basis that Defendant was "willfully blind" to the patent by having a policy of not reviewing patents of others ([Compl. ¶17](https://ex:cit:4)). The complaint further alleges Defendant's actions were objectively reckless ([Compl. ¶18](https://ex:cit:5)).

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

  1. Evidentiary Sufficiency: The most immediate challenge for the plaintiff will be substantiating its factually thin complaint. Can it produce evidence demonstrating that the Lululemon app performs each specific step of Claim 7, particularly the execution of a "questionnaire," the automatic provision of GPS data as a response, and the subsequent "making available" of collected data via the Internet?
  2. Definitional Scope: A core legal issue will be one of claim construction. Can the term "questionnaire," rooted in the patent's 2002-era context of structured data forms, be construed broadly enough to encompass the potentially more dynamic and less formal user interactions of a modern retail mobile application?
  3. Impact of Patent History: A key strategic question is how the patent's robust post-issuance history—surviving two IPRs on the asserted claim and receiving a favorable validity ruling in prior litigation—will shape the proceedings. While not preclusive against this defendant, this history may influence the court’s perspective and the parties' risk assessment.
