pr1or.art Inc., “Advanced Bacillus Subtilis Strains for Specialized Feed,” Published Technical Disclosure No. 24-11856970_0009_PTD, Published October 26, 2025, available at https://archive.pr1or.art/24-11856970_0009_PTD
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. 11,856,970.

Background and Problem Solved

The original patent disclosed Bacillus subtilis strains for general animal feed applications. However, these strains may not be effective in specific, niche environments. This invention addresses the limitations of the original patent by developing specialized strains tailored to these unique contexts.

Novelty and Inventive Step

The new claims introduce novel adaptations of the Bacillus subtilis strain for specific, niche environments, which are not obvious from the original patent. The inventive step lies in the development of specialized strains that address the unique challenges of these environments, such as high-altitude regions, extreme weather conditions, disaster relief, and high-security facilities.

Alternative Embodiments and Variations

Alternative embodiments could include adapting the Bacillus subtilis strain for other niche environments, such as marine or space-based applications. Variations could include combining the Bacillus subtilis strain with other microorganisms or nutrients to further enhance its effectiveness.

Potential Commercial Applications and Market

This invention has significant commercial potential in the animal feed industry, particularly in regions with extreme environmental conditions. The target market includes animal feed manufacturers, farmers, and distributors operating in high-altitude regions, extreme weather conditions, disaster relief, and high-security facilities.
