What This Patent Covers

This patent protects a comprehensive system and method for evaluating food mastication, covering signal acquisition from left and right throat microphones, AI learning model-based likelihood identification of chewing events (right-sided, left-sided) and blank periods, and the final determination of chewing completion. Its broad and robust claim structure, having overcome four cited prior art documents during examination, indicates strong novelty and inventiveness, making infringement difficult to circumvent.

Competitive White Space

This patent primarily covers AI-driven chewing analysis via throat microphones. White space exists in integrating this data with other biometric inputs like muscle activity or tongue pressure, or developing real-time biofeedback systems for dysphagia rehabilitation.

ROI Calculation Logic

Aspiration pneumonia inpatient treatment costs are estimated at ~$10,000/person annually (AI est.). If this technology prevents aspiration pneumonia in 10% of 100 facility residents, the annual cost savings could be ~$10,000/person × 10 people = ~$100,000 (AI est.). Additionally, an estimated ~$70,000/year (AI est.) in labor cost reduction from reduced supervision in care settings could be achieved, totaling over ~$170,000/year in economic benefits.

Speed to Market
6× faster than in-house development
This technology features established technical logic for extracting features from throat microphone audio signals and using a learning model-based classifier to determine chewing events. Key components, such as skin-contact microphones and AI learning models, are already mature existing technologies. This allows licensees to bypass fundamental research and algorithm development phases, enabling integration into existing wearable devices or IoT systems, potentially shortening development time by approximately 2.5 years compared to in-house development.
