No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint's infringement allegations are stated at a high level without a detailed mapping of product features to claim limitations. The following table summarizes the infringement theory based on the available allegations for Claim 7 of the '748 Patent.

'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 on a first computer platform...	The complaint alleges that the Gap Mobile Apps, in conjunction with Gap servers, "create... a location-specific questionnaire."	¶11	col. 14:7-17
(b) automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto;	The complaint alleges Defendants provide the "Gap Mobile Apps" to customers' mobile devices, which are GPS-enabled computers.	¶11	col. 14:46-50
(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 complaint alleges the accused products "execute a location-specific questionnaire to collect responses from users."	¶11	col. 14:51-56
(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 does not provide sufficient detail for analysis of this element. It alleges a "location-specific" questionnaire but does not specify that GPS data is used as a response.	¶11	col. 14:57-60
(e) automatically transferring via the loose network any responses so collected in real time to a central computer; and,	The complaint alleges the system "collect[s] responses from users" and involves "Gap servers," which may function as the central computer. The "real time" aspect is not explicitly detailed.	¶11	col. 14:61-64
(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. No facts are alleged regarding this step.	N/A	col. 14:65-67

• Identified Points of Contention:
  • Evidentiary Questions: The complaint's allegations are conclusory and lack specific facts. A primary point of contention will be whether the accused apps actually perform every step of the claimed method. The complaint provides no factual support for the allegations that the apps use GPS data as a response to a questionnaire (element d) or that collected responses are made available via the Internet (element f). The absence of allegations for the final claim step may present a challenge to the sufficiency of the pleadings.
  • Scope Questions: The interpretation of "questionnaire" will be critical. The dispute may center on whether simple location-triggered notifications or offers within a retail app constitute a "questionnaire" with "branching logic," or if the term requires a more structured, survey-like interaction as detailed in the patent's "mystery shopper" embodiment '748 Patent, col. 10:40-11:21

V. Key Claim Terms for Construction

• The Term: "questionnaire"

• Context and Importance: This term is the central object of the claimed method. Its construction will determine whether the claim covers a broad range of location-based mobile interactions or is limited to more formal, multi-question data collection tools. Practitioners may focus on this term because its breadth is a dispositive issue for infringement.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification suggests the term can be interpreted broadly, defining it as "posing a series of questions, or otherwise prompting for specific input from the user" '748 Patent, col. 5:39-42, which could potentially encompass simple interactive prompts.
  • Evidence for a Narrower Interpretation: The patent's detailed "mystery shopper" example illustrates a complex, multi-step process with numerous questions, timers, and data entry fields '748 Patent, col. 10:40-11:21 This specific embodiment, along with the common understanding of the word, may support a narrower construction requiring a structured set of questions designed to elicit specific information.

• The Term: "loosely networked computer"

• Context and Importance: This term defines the type of device on which the method is performed. Its definition is important for establishing the technological environment of the claim.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent itself 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 functionality is inherent in modern smartphones that manage connections between Wi-Fi, cellular, and offline states.
  • Evidence for a Narrower Interpretation: A party could argue the term requires a specific software architecture designed for store-and-forward functionality, rather than just the default behavior of a modern mobile operating system. However, the patent's own explicit definition appears to favor a broader reading that describes a functional capability rather than a specific implementation.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by claiming Defendants took active steps with specific intent, such as "advising or directing customers" and distributing instructions to use the accused apps in an infringing manner Compl. ¶16 It also alleges contributory infringement by asserting the apps have "special features" that are material to the invention and not suitable for substantial non-infringing use Compl. ¶17
• Willful Infringement: The willfulness claim is based on alleged knowledge of the '748 Patent "at least as of the date when it was notified of the filing of this action" Compl. ¶18 The complaint further alleges willful blindness, contending that Defendants have a "policy or practice of not reviewing the patents of others" Compl. ¶19 and that their infringement is "objectively reckless" Compl. ¶20

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

• An Evidentiary Question of Completeness: A central issue will be whether Plaintiff can produce evidence that Defendants' mobile apps perform every step of the asserted method claim. The complaint is silent on key steps, including whether GPS data is used as a response and whether collected data is made available via the Internet. The failure to plead facts supporting all elements of the claim may be an early focus of the litigation.

• A Definitional Question of Scope: The case will likely turn on the construction of the term "questionnaire". The court will need to determine if the simple, location-aware marketing features common in modern retail apps can be construed as the structured, interactive "questionnaire" with "branching logic" required by Claim 7, or if the term demands a more formal survey-like function.

• A Question of Validity: While validity is at issue in every patent case, the fact that the asserted claim (Claim 7) has already survived an inter partes review at the Patent Trial and Appeal Board-as evidenced by the patent's own public file-significantly strengthens its presumption of validity and will likely narrow the scope of invalidity arguments Defendants can effectively raise.
