Prior art — US Patent 12423718

As a senior US patent analyst, I have analyzed the prior art cited during the prosecution of US patent 12,423,718. The following represents the most relevant references and their potential impact on the patent's claims.

The analysis is based on the claims as summarized in the previously generated sections. The core inventive concept of US patent 12,423,718 is the combination of a demographic intelligence module (determining characteristics like age/gender from sensors) with a tracking module (monitoring a person's path, e.g., via Wi-Fi/MAC address) to link demographic data with physical behavior in a retail setting for analysis and real-time engagement.

Cited Prior Art Analysis

The following patents were cited by the USPTO examiner during the prosecution of the application that led to US patent 12,423,718.

1. US Patent 8,930,241 B2 ("Shopper-aware retail store system")

Full Citation: US 8,930,241 B2, "Shopper-aware retail store system," assigned to International Business Machines Corporation (IBM).
Dates: Filed: July 29, 2011; Published: January 6, 2015. This predates the priority date of US '718 (July 19, 2013).
Brief Description: The '241 patent discloses a system for identifying shoppers in a retail store and providing them with personalized content. It describes using cameras to capture images of shoppers, performing facial recognition to identify them, and tracking their location within the store. The system then accesses a shopper's profile (which can include demographic data, purchase history, and preferences) to present targeted advertisements or promotions on nearby digital displays.
Potential Anticipation of Claims: This reference appears highly relevant and potentially anticipates the core elements of all independent claims.
- System Claim: The '241 patent discloses a server ("central store server"), information monitoring devices ("video cameras," "location sensors"), databases ("shopper profile database"), and software modules. Crucially, its facial recognition and profile lookup functions perform the role of a "demographic intelligence module," and its location-monitoring capabilities function as a "tracking module." The system explicitly links the identified shopper (demographics) with their location (tracking).
- Method Claim: It describes the method of gathering information via cameras and sensors, analyzing it to identify the shopper and their location, and linking that information to deliver targeted content. This maps directly to the steps of gathering and analyzing data using both demographic and tracking functionalities.
- Computer-Readable Medium Claim: The software described to perform the method would be covered.

2. US Patent 9,514,463 B2 ("System and method for audience analysis using anonymous video analytics")

Full Citation: US 9,514,463 B2, "System and method for audience analysis using anonymous video analytics," assigned to Microsoft Technology Licensing, LLC.
Dates: Filed: May 20, 2011; Published: December 6, 2016. This predates the priority date of US '718.
Brief Description: The '463 patent details a system that uses video cameras to anonymously analyze an audience viewing a display (e.g., a digital sign). The system determines demographic information such as age range, gender, and viewing duration for individuals and groups without identifying them personally. It can then change the content on the display in real-time based on the detected demographics of the current audience.
Potential Anticipation of Claims: This reference is strong prior art for the "demographic intelligence module" but is weaker on the "tracking module" element.
- System/Method Claims: The '463 patent clearly discloses a "demographic intelligence module" that analyzes video to determine age and gender. It also discloses a server, cameras, and displays. However, its primary focus is on analyzing viewers at a fixed location (in front of a display) rather than continuously tracking a person's path throughout a larger area like a retail store. An argument could be made that it does not fully disclose the "tracking module" as claimed in the '718 patent, which specifies tracking a person's movement "within a predetermined area."

3. US Patent Application Publication 2012/0310707 A1 ("Systems and Methods for Monitoring and Reporting Consumer Traffic")

Full Citation: US 2012/0310707 A1, "Systems and Methods for Monitoring and Reporting Consumer Traffic," assigned to RetailNext, Inc.
Dates: Filed: June 1, 2012; Published: December 6, 2012. This predates the priority date of US '718.
Brief Description: This publication describes a comprehensive in-store analytics platform. It explicitly discloses combining data from various sensors, including video cameras for demographic analysis (gender, age) and Wi-Fi/Bluetooth sensors to track mobile devices (via MAC addresses) as proxies for shoppers. The system integrates this data to create detailed reports on traffic patterns, dwell times, and customer demographics throughout the store.
Potential Anticipation of Claims: This is another highly relevant reference that appears to disclose all key elements of the claims.
- System Claim: The '707 publication discloses a complete system with servers, databases, and multiple "information monitoring devices." It explicitly teaches a video-based "demographic intelligence module" and a Wi-Fi-based "tracking module" using MAC addresses, which is a specific embodiment described in the '718 patent itself.
- Method Claim: It describes the method of gathering demographic data from video and location data from Wi-Fi signals and then "linking" or "fusing" this information for analysis and reporting. This directly aligns with the method claimed in '718.
- Computer-Readable Medium Claim: The software enabling this data fusion and analysis is inherently described.

Summary of Prior Art Impact

Based on this analysis, US patent 12,423,718 faces significant validity challenges from the cited prior art, particularly from US 8,930,241 B2 (IBM) and US 2012/0310707 A1 (RetailNext). Both references appear to teach the core claimed invention: a system that combines a demographic analysis component with a separate location tracking component to analyze customer behavior in a physical space. The RetailNext publication is especially compelling as it describes the specific embodiment of using video for demographics and Wi-Fi MAC address tracking for location, just as detailed in the '718 patent.
