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 creating software for handheld computers was challenging due to incompatible hardware and operating systems, requiring custom-coded applications for each device type Compl. ¶22 '948 Patent, col. 1:49-2:2 This process was expensive and inefficient, especially for deploying updates Compl. ¶24 '948 Patent, col. 3:1-10 Furthermore, these devices often had intermittent or "loose" network connectivity, making real-time data transfer unreliable Compl. ¶26 '948 Patent, col. 3:64-4:1
    • The Patented Solution: The invention proposes a system to overcome these issues by using "device-indifferent tokens" to create a "questionnaire" on a central server Compl. ¶25 '948 Patent, col. 4:66-5:2 This tokenized questionnaire can then be transmitted to and executed on various types of remote devices without needing device-specific compilation Compl. ¶25 '948 Patent, col. 5:21-25 The system is designed for "loosely networked" environments, storing data on the device if a connection is unavailable and transmitting it later Compl. ¶26 '948 Patent, col. 5:7-12 The invention also integrates GPS to automate the collection of location information and trigger location-specific questionnaires Compl. ¶27 '948 Patent, col. 10:55-65
    • Technical Importance: The patented approach sought to significantly lower the cost and complexity of deploying data-gathering applications on a heterogeneous fleet of mobile devices, enabling more timely and accurate data collection from the field compared to paper-based or batch-processed electronic systems Compl. ¶24 '948 Patent, col. 2:41-54

  • Key Claims at a Glance:

    • The complaint explicitly asserts independent Claim 7 Compl. ¶11
    • The essential elements of independent Claim 7 include:
      • Designing a questionnaire customized for a location, with branching logic and a request for location information.
      • Automatically transferring the questionnaire to a "loosely networked computer" with a GPS.
      • Executing the questionnaire on the device when it is at the specified location to collect responses.
      • Using the GPS to automatically provide location information as a response.
      • Automatically transferring collected responses in real-time over the loose network to a central computer.
      • Making the transferred responses available via the Internet.
    • The complaint's prayer for relief seeks judgment on "one or more claims," reserving the right to assert others Compl. prayer a

III. The Accused Instrumentality

  • Product Identification: The "Sport Clips mobile apps" operating "in conjunction with Sport Clips 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 complaint also states that Sport Clips uses its app to "direct customers to, and allow customers to check in for, one or more Sport Clips locations" Compl. ¶5 The core accused functionality appears to be the mobile "check in" feature offered to customers. The complaint does not provide sufficient detail for analysis of the product's market positioning beyond its use by Sport Clips customers.

IV. Analysis of Infringement Allegations

No probative visual evidence provided in complaint.

The complaint alleges infringement of Claim 7 but does not provide a detailed element-by-element mapping. The following table summarizes the likely infringement theory based on the general allegations.

'748 Patent Infringement Allegations

Claim Element (from Independent Claim 7) Alleged Infringing Functionality Complaint Citation Patent Citation
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 The complaint alleges the Sport Clips system "create[s] and execute[s]" a "location-specific questionnaire." ¶10 col. 14:48-54
automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto The Sport Clips App is transferred (downloaded) to users' mobile phones, which are GPS-enabled, loosely networked computers. ¶10 col. 14:55-58
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 When at a Sport Clips location, a customer uses the app to "check in," which the complaint characterizes as executing the questionnaire and collecting a response. ¶5; ¶10 col. 14:59-63
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 does not specify how location is provided but implies the app's location-specific check-in function satisfies this element. ¶10 col. 14:64-67
automatically transferring via the loose network any responses so collected in real time to a central computer The "check in" data is transferred from the user's mobile app to Sport Clips' central servers. ¶10 col. 15:1-4
making available via the Internet any responses transferred to said central computer in step (e) The complaint does not provide details on how the collected check-in data is made available via the internet. ¶10 col. 15:5-7
  • Identified Points of Contention:
    • Scope Question: A primary issue may be whether the "check in" feature of the Sport Clips app constitutes a "questionnaire" that "collect[s] responses from a user" as that term is used in the patent, which provides detailed examples of multi-question surveys with branching logic (e.g.,'748 Patent, col. 10:37-11:21).
    • Technical Question: What evidence supports the allegation that the accused system uses GPS to automatically provide location information as a response to the questionnaire, as required by element (d)? The system could potentially rely on user selection of a store from a list, which may not meet the claim's requirement for automatic GPS-based input.
    • Evidentiary Question: The complaint provides no facts to support the final step of the claim: "making available via the Internet any responses." The patent specification describes this step in the context of a client accessing a web portal to review survey results '748 Patent, col. 10:10-13 A key question is whether Sport Clips' internal use of check-in data satisfies this limitation and what evidence Plaintiff will offer to prove it.

V. Key Claim Terms for Construction

  • The Term: "questionnaire"

    • Context and Importance: The viability of the infringement case hinges on whether the accused "check-in" process is legally equivalent to the claimed "questionnaire." Defendant will likely argue for a narrow construction limited to multi-question surveys, while Plaintiff will argue for a broader meaning covering any structured data collection.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent uses the term "questionnaire" interchangeably with "form" '748 Patent, col. 8:38-40 and describes its purpose as the "collection and management of information" generally '748 Patent, col. 1:17-18, suggesting the term is not limited to a specific format.
      • Evidence for a Narrower Interpretation: The detailed "mystery shopper" embodiment describes a complex, multi-step data entry process involving timers, conditional logic, and numerous specific questions '748 Patent, col. 10:37-11:21 A court might see this as defining the term's scope as something more involved than a simple check-in.

  • The Term: "making available via the Internet"

    • Context and Importance: This is the final, dispositive step of the claimed method. Its interpretation will be critical, as the complaint is silent on facts supporting it.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The claim language itself does not specify to whom or for what purpose the responses must be made available. An interpretation could be advanced that any storage on an internet-accessible server for internal review meets this limitation.
      • Evidence for a Narrower Interpretation: The specification consistently frames this step as providing a client with access to review collected data. For example, "A client can then use a computer...with Internet access to review or use the data from virtually anywhere in the world" '748 Patent, col. 10:10-13 This suggests a specific user-facing functionality beyond mere internal data processing.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that Sport Clips induced infringement by advising, directing, advertising, and providing instructions for customers to use the accused app Compl. ¶15 Contributory infringement is alleged on the basis that the app has special features 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 and, on information and belief, a policy of "willfully blind[ing]" itself to the patent rights of others Compl. ¶18

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

  1. A question of definitional scope: Will the accused "check-in" functionality be construed as a "questionnaire" under the patent's claim language, or will the patent's detailed "mystery shopper" embodiment limit the term to a more complex, multi-question data-gathering tool?
  2. An evidentiary question of technical operation: What evidence will be presented to show that the accused app performs the specific automated functions of Claim 7, particularly the use of GPS to automatically provide location as a response and the subsequent act of making responses available via the Internet as contemplated by the patent's specification?
  3. A question of preclusion and litigation strategy: Given that the asserted Claim 7 has already been confirmed as patentable in an IPR proceeding and its patent family has survived a § 101 challenge in prior litigation, the central battleground will likely shift from validity to the factual and legal nuances of the infringement analysis.
