pr1or.art Inc., “Lactiplantibacillus plantarum TCI837 for Cosmetic and Wellness Applications,” Published Technical Disclosure No. 24-11857583_0007_PTD, Published October 28, 2025, available at https://archive.pr1or.art/24-11857583_0007_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. 11,857,583.

Summary of the Inventive Concept

The present inventive concept leverages the core technology of Lactiplantibacillus plantarum TCI837 to develop novel applications in the cosmetic and wellness industries, expanding its use beyond iron supplementation.

Background and Problem Solved

The original patent disclosed the use of Lactiplantibacillus plantarum TCI837 for iron supplementation. However, the cosmetic and wellness industries have been seeking innovative solutions to address skin health, acne, stress, and wound healing. The present inventive concept addresses these unmet needs by applying the core technology of Lactiplantibacillus plantarum TCI837 to these new areas.

Detailed Description of the Inventive Concept

The new inventive concept comprises the use of Lactiplantibacillus plantarum TCI837 in topical applications, oral administrations, and cosmetic compositions to promote healthy skin, treat acne, reduce stress and anxiety, and enhance wound healing. The Lactiplantibacillus plantarum TCI837 modulates the skin microbiome, regulates sebum production, and stimulates collagen production, leading to improved skin elasticity, reduced inflammation, and enhanced tissue repair.

Novelty and Inventive Step

The new claims introduce a novel and non-obvious application of Lactiplantibacillus plantarum TCI837 beyond iron supplementation, demonstrating an inventive step in the development of cosmetic and wellness products.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept include the use of Lactiplantibacillus plantarum TCI837 in combination with other probiotics or active ingredients, varying the dosage and administration routes, and developing customized products for specific skin types or conditions.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the cosmetic and wellness industries, with a growing market demand for innovative, natural, and effective solutions for skin health, acne, stress, and wound healing.

Field of Art

Microbiology, Probiotic Applications, and Biotechnology with a focus on Lactiplantibacillus plantarum and its therapeutic/cosmetic uses

Person of Ordinary Skill (PHOSITA) Profile

A researcher or practitioner with expertise in microbiology, probiotic strain development, and biotechnological applications, holding at least a Master's degree with experience in microbiome research and bacterial strain characterization

Obviousness Rationale

A PHOSITA would recognize that the unique properties of Lactiplantibacillus plantarum TCI837, particularly its ability to modulate biological systems, naturally extend beyond iron supplementation to other physiological applications. The strain's demonstrated capacity to interact with human biological systems suggests predictable variations in therapeutic and cosmetic uses. The technical characteristics that enable iron absorption and metabolic regulation would similarly support skin microbiome modulation and stress response mechanisms.
