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. 11,856,953.

Background and Problem Solved

The original patent provides a launderable bactericidal and virucidal fabric finish for textiles, addressing the issue of microorganisms on fabrics. However, the problem of airborne pathogens remains a significant concern in various industries, including public transportation, healthcare, and athletic facilities. The present invention addresses this limitation by applying the core technology to entirely new applications, providing a novel solution for mitigating airborne pathogens.

Novelty and Inventive Step

The new claims introduce a novel application of the launderable bactericidal and virucidal fabric finish, extending its use beyond textiles to mitigate airborne pathogens in various settings. This inventive step lies in the recognition of the finish's potential to address a broader range of problems, beyond its original intended use.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include using different fabric types, incorporating additional antimicrobial agents, or integrating the finish with existing air filtration systems. Variations of the wearable device may include different designs, such as masks or scarves, to provide individuals with versatile protection options.

Potential Commercial Applications and Market

The invention has significant commercial potential in various industries, including public transportation, healthcare, athletic facilities, and consumer products. The market for airborne pathogen mitigation solutions is substantial, with a growing demand for effective and safe solutions to address the spread of viruses and bacteria.
