pr1or.art Inc., “Advanced Stevia Sweetener for Extreme Environments,” Published Technical Disclosure No. 24-11856974_0009_PTD, Published October 26, 2025, available at https://archive.pr1or.art/24-11856974_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. 11,856,974.

Background and Problem Solved

The original patent disclosed a process for preparing highly soluble individual or combined sweet glycosides from a Stevia rebaudiana Bertoni plant extract. However, the original patent did not address the limitations of using such sweeteners in specific, challenging environments. This new invention addresses these limitations by providing adapted solutions for high-altitude environments, emergency food supplies, extreme weather conditions, remote or disaster-stricken areas, and high-security applications.

Novelty and Inventive Step

The new claims demonstrate novelty and inventive step by introducing specialized adaptations of the original highly soluble stevia sweetener technology to address specific challenges in niche environments, such as high-altitude environments, emergency food supplies, extreme weather conditions, remote or disaster-stricken areas, and high-security applications.

Alternative Embodiments and Variations

Alternative embodiments of this invention could include adaptations for other niche environments, such as space exploration, military operations, or high-temperature applications. Variations could also involve different types of sweetener compositions or production methods.

Potential Commercial Applications and Market

This invention has significant commercial potential in various industries, including food and beverage, pharmaceuticals, and emergency relief. The adapted solutions for high-altitude environments, emergency food supplies, extreme weather conditions, remote or disaster-stricken areas, and high-security applications can cater to specific market needs, providing a competitive edge in these niche markets.
