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 disclosed a launderable bactericidal and virucidal fabric finish for home laundry, but its application was limited to personal use. However, the growing concern about airborne pathogens and hospital-acquired infections demands a more comprehensive solution. This invention addresses these limitations by expanding the application of the core technology to diverse industries, providing a critical tool in the fight against infectious diseases.

Novelty and Inventive Step

The novelty of this invention lies in its expansion of the original patent's technology to new industries and applications, providing a unique solution to the pressing problem of airborne pathogens and hospital-acquired infections. The inventive step is the identification of the specific formulation and application methods required for each industry, demonstrating a non-obvious and innovative approach to addressing these critical challenges.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include varying the concentration of the bactericidal and virucidal agent, using different types of crosslinkers or catalysts, or incorporating additional components to enhance the fabric finish's performance. Variations of the invention may also involve adapting the application method to accommodate different surface materials or environmental conditions.

Potential Commercial Applications and Market

The invention has significant commercial potential in various industries, including aircraft manufacturing, public transportation, healthcare, and fitness. The market demand for effective solutions to reduce the spread of airborne pathogens and transmission of infections is substantial, and this invention is poised to capitalize on this need, providing a valuable tool for industries seeking to protect public health and safety.
