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 describes a technical landscape in the early 2000s where software applications for handheld computers were difficult to develop and deploy across different hardware and operating systems Compl. ¶22 '748 Patent, col. 1:49-2:2 This "compatibility issue" meant applications often had to be custom-coded and re-compiled for each device type, a costly and inefficient process Compl. ¶24 '748 Patent, col. 2:41-44 Furthermore, handheld devices in the field often faced intermittent network connectivity, making real-time data collection and synchronization with a central server problematic Compl. ¶22 '748 Patent, col. 3:64-4:1
• The Patented Solution: The invention proposes a system that uses "device-indifferent tokens" to create and execute data-collection "questionnaires" Compl. ¶25 A questionnaire is designed on a central system and then transmitted as a set of tokens to remote handheld devices '748 Patent, col. 9:4-14 Because the tokens are device-independent, the same questionnaire can run on different types of devices without recompilation, as long as each device has a compatible runtime engine '748 Patent, col. 5:14-20 The system also handles poor network connectivity through a "loosely networked" approach: if a connection is available, data is sent in real time, but if not, it is stored locally and transmitted when the connection is restored Compl. ¶26 '748 Patent, col. 5:7-12 The patent also specifically teaches using an integrated GPS to automate the collection of location information and customize the questionnaire for a particular location Compl. ¶27 '748 Patent, col. 10:55-65
• Technical Importance: This solution enabled the creation of flexible, scalable data collection applications that could function across a diverse range of mobile devices and in environments with unreliable network access, a significant challenge for enterprise mobile computing at the time. Compl. ¶7

Key Claims at a Glance

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

'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 wherein at least one of said at least one questions requests location identifying information	Sephora, using its servers, creates a "location-specific questionnaire" for its mobile app.	¶10	col. 14:48-59
(b) automatically transferring said designed questionnaire to at least one loosely networked computer having a GPS integral thereto	Sephora distributes its mobile app, containing the questionnaire, to users' mobile devices, which are loosely networked computers with integrated GPS.	¶10	col. 14:60-63
(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 Sephora Mobile App executes the location-specific questionnaire on the user's device to collect responses.	¶10	col. 15:1-4
(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 specify how this function is performed, but alleges general infringement of the claim which includes this limitation.	¶11	col. 15:5-8
(e) automatically transferring via the loose network any responses so collected in real time to a central computer	The Sephora Mobile App, in conjunction with Sephora servers, collects responses from users, which implies transfer to a central computer (the server).	¶10	col. 15:9-12
(f) making available via the Internet any responses transferred to said central computer in step (e)	The complaint does not specify how this function is performed, but alleges general infringement of the claim which includes this limitation.	¶11	col. 15:13-15

Identified Points of Contention

• Scope Questions: The case may turn on whether features of a modern e-commerce application, such as a store locator that prompts for a user's location, can be construed as a "questionnaire" as the term is used in the patent. The patent's examples focus on more structured, survey-style data collection (e.g., a "mystery shopper" report) '748 Patent, col. 9:41-11:26, raising the question of a potential scope mismatch.
• Technical Questions: A significant technical question is what evidence the plaintiff will produce to show that the Sephora app "automatically provide[s] said location identifying information as a response to said executing questionnaire," as required by element 7(d). The complaint does not provide facts to distinguish between an app generally using location services versus an app specifically populating a "response" field with GPS data as part of a formal questionnaire process. A similar evidentiary question exists for element 7(f) regarding how the collected "responses" are made "available via the Internet."

V. Key Claim Terms for Construction

The Term: "questionnaire"

• Context and Importance: This term is foundational to the claim. Its construction will determine whether a wide range of modern mobile app interactions fall within the claim's scope. Practitioners may focus on this term because the defendant will likely argue that a simple prompt in a retail app (e.g., a store locator) is not the multi-question, survey-like "questionnaire" taught in the patent.
• 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 its creation by constructing a "series of questions or statements, each of which calls for a response" '748 Patent, col. 8:26-29 This could support an interpretation that any structured data-gathering prompt is a "questionnaire."
• Evidence for a Narrower Interpretation: The detailed "mystery shopper" example describes a complex, multi-step process with timers, conditional logic, and numerous specific questions about a user's experience '748 Patent, col. 9:41-11:26 This could support a narrower construction requiring a more formal, survey-like instrument.

The Term: "customized for a particular location"

• Context and Importance: This term's definition is critical for determining what level of location-based adaptation is required for infringement. Practitioners may focus on this term to dispute whether using location data to provide a generic service (like listing nearby stores) meets the "customized for" limitation.
• Evidence for a Broader Interpretation: The patent claims a method of "creating a questionnaire...customized for a location" '748 Patent, cl. 1(a) Plaintiff could argue that any questionnaire whose function or trigger is tied to a location meets this requirement.
• Evidence for a Narrower Interpretation: The patent teaches creating questionnaires for "particular locations" and executing them "when the remote computing devices is at certain locations" '748 Patent, col. 10:59-65 This might suggest the questionnaire's content must be specifically tailored to a location, rather than simply being enabled by location data.

VI. Other Allegations

Indirect Infringement

The complaint alleges inducement by asserting that Sephora directs and instructs customers to use the accused app in an infringing manner through advertising, promotion, and user instructions Compl. ¶15 It also alleges contributory infringement, claiming the app has "special features" with no substantial non-infringing use, which may be a point of contention for a general-purpose retail app Compl. ¶16

Willful Infringement

The complaint bases its willfulness allegation on Defendant's knowledge of the patent "at least as of the date when it was notified of the filing of this action" Compl. ¶17 It also 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", rooted in the patent's context of structured data collection forms, be construed to cover modern e-commerce app features like a store locator that uses location data? The outcome of this claim construction will be pivotal.
• A key evidentiary question will be one of technical function: Does the Sephora app perform the specific step of "using said GPS to automatically provide said location identifying information as a response to said executing questionnaire" as required by Claim 7(d)? The complaint's conclusory allegations will require factual support to demonstrate that the accused app's use of location services matches this precise claim limitation, as opposed to a more general use.
• A third question relates to validity in light of prosecution history: Given that Claim 7 has survived both an IPR proceeding and a Section 101 challenge in prior litigation Compl. ¶27 '748 K1 Certificate, the case may focus more intensely on non-infringement arguments, as the patent's validity has already been successfully defended against significant challenges.
