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, but lacked specific adaptations for unique operational environments. This invention addresses the limitations of the original patent by providing specialized strains and compositions tailored to specific niches, thereby expanding the range of applications and improving overall efficacy.

Novelty and Inventive Step

The new claims introduce novel and non-obvious adaptations of the original Bacillus subtilis strains and compositions, specifically designed to address the unique challenges of high-altitude regions, disaster relief zones, extreme weather conditions, high-security facilities, and remote or isolated areas. The inventive step lies in the recognition of the need for specialized solutions in these niches and the development of tailored compositions and methods to meet those needs.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different bacterial strains or combinations of strains, variations in the composition of the feed additives, or modifications to the kit and system designs. Additionally, the invention could be adapted for use in other animal species or in human nutrition.

Potential Commercial Applications and Market

The invention has significant commercial potential in the animal feed industry, particularly in niches where specialized solutions are in high demand. Target industries include animal feed manufacturers, agricultural companies, and organizations involved in disaster relief and high-security operations. The invention could also have applications in human nutrition and other areas where tailored probiotic solutions are needed.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Animal nutrition, microbiology, and feed additives with a focus on probiotic bacterial strains for animal health, specifically involving Bacillus subtilis applications in veterinary and agricultural contexts

Person of Ordinary Skill (PHOSITA) Profile

A microbiologist or veterinary nutritionist with expertise in bacterial strain selection, feed additive formulation, and understanding of probiotics' role in animal gut health, possessing knowledge of bacterial strain characteristics, fermentation techniques, and animal nutrition principles

Obviousness Rationale

A PHOSITA would recognize that the PTD's variations represent predictable extensions of the source patent's core technology by applying known methodological adaptations to the established Bacillus subtilis strain. The disclosed variations demonstrate standard problem-solving approaches in animal nutrition by tailoring the probiotic strain and delivery mechanism to specific environmental constraints. These modifications represent routine engineering design choices within the established technological framework of the source patent.

Obvious Combinations & Variations

Source Patent Element

Bacillus subtilis strain DSM 32685 with antibiotic susceptibility and bacterial inhibition properties

PTD Variation

Specialized feed additive for high-altitude regions incorporating the same bacterial strain

Obviousness Reasoning

Adapting a known probiotic strain to specific environmental conditions represents a predictable variation using standard formulation techniques known to those skilled in animal nutrition

Source Patent Element

Method of administering Bacillus subtilis in animal feed to improve performance parameters

PTD Variation

Kit for producing animal feed in extreme weather conditions using the same bacterial strain

Obviousness Reasoning

Developing specialized delivery mechanisms for a known probiotic strain is an obvious design choice that addresses environmental challenges using routine engineering problem-solving

Source Patent Element

Composition comprising Bacillus subtilis with potential co-administration of other bacterial genera

PTD Variation

System for monitoring bacterial populations in remote areas using the bacterial strain with integrated sensor technology

Obviousness Reasoning

Integrating monitoring technologies with an established probiotic strain represents a logical extension of existing microbiological tracking methodologies

Source Patent Element

Method of inhibiting bacterial colonization using Bacillus subtilis

PTD Variation

Specialized antimicrobial composition for high-security facilities using the bacterial strain

Obviousness Reasoning

Tailoring an existing bacterial inhibition method to specific institutional requirements represents a standard approach to technological adaptation

35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11856970, the variations disclosed herein would be considered obvious to a person having ordinary skill in the art, as they represent predictable modifications of an established Bacillus subtilis probiotic strain through routine engineering adaptations that would be apparent to a skilled practitioner without requiring inventive insight. The disclosed variations constitute prima facie obvious extensions of the prior art that do not meet the non-obviousness requirements of 35 U.S.C. § 103.
