This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,001.

Background and Problem Solved

The original patent disclosed antiviral, antibacterial, and antifungal compositions, systems, methods, and devices, particularly silicon nitride compositions for inactivating and lysing viruses, bacteria, and fungi. However, these solutions were limited to individual components or devices. The present invention addresses the need for a more comprehensive and interconnected system that combines the strengths of multiple technologies to provide enhanced pathogen protection and monitoring.

Novelty and Inventive Step

The new claims introduce a novel combination of distinct technologies, creating a more powerful system that surpasses the capabilities of individual components. The integration of AI, IoT, blockchain, and advanced materials with antipathogenic face masks provides a non-obvious solution that addresses the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include integrating the antipathogenic face mask with other wearable devices, such as smartwatches or fitness trackers, or incorporating additional sensors for detecting other environmental factors. Variations may also include using different materials or combinations of materials for the face mask, or adapting the system for use in different settings, such as hospitals or public spaces.

Potential Commercial Applications and Market

The invention has significant commercial potential in the healthcare, wellness, and safety industries, particularly in the context of pandemic preparedness and response. The integrated system can be marketed as a comprehensive solution for individuals, businesses, and governments seeking to enhance pathogen protection and monitoring capabilities.
