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. 11,857,578.

Summary of the Inventive Concept

This inventive concept presents a suite of improvements and enhancements to the original bacterial extract-based dermatological composition, offering faster, safer, and more efficient treatment options for sensitive skin.

Background and Problem Solved

The original patent disclosed a novel bacterial extract for treating sensitive skin, but it had limitations in terms of extraction methods, stability, and personalized treatment. This new inventive concept addresses these limitations by introducing novel microfluidic extraction, enhanced stability through lyophilization, and personalized treatment options.

Detailed Description of the Inventive Concept

The inventive concept comprises four key aspects: (1) a novel microfluidic extraction method for obtaining bacterial extracts, (2) a method for enhancing the stability of the extract through lyophilization, (3) a dermatological composition that combines the bacterial extract with an anti-inflammatory agent, and (4) a system for real-time monitoring of skin inflammation and personalized treatment. These aspects work in tandem to provide a more efficient, safe, and personalized treatment for sensitive skin.

Novelty and Inventive Step

The new claims introduce novel and non-obvious improvements to the original patent, including the use of microfluidic extraction, lyophilization for stability, and personalized treatment options. These enhancements demonstrate a significant inventive step beyond the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different microfluidic extraction methods, varying stabilizing agents, or alternative anti-inflammatory agents. Additionally, the system for real-time monitoring and personalized treatment could be adapted for use with other skin conditions or therapeutic areas.

Potential Commercial Applications and Market

The enhanced bacterial extract-based solutions have significant commercial potential in the dermatological and cosmetic industries, particularly in the growing market for sensitive skin treatments. The inventive concept's focus on personalized treatment and real-time monitoring also opens up opportunities for digital health and telemedicine applications.

Field of Art

Dermatological biotechnology, focusing on bacterial extract development for skin treatment, with expertise in microbiology, extraction techniques, and dermatological formulation

Person of Ordinary Skill (PHOSITA) Profile

A researcher with advanced degrees in microbiology or biotechnology, experienced in bacterial strain isolation, extract preparation, and dermatological product development, familiar with microfluidic technologies and skin inflammation treatment strategies

Obviousness Rationale

A person skilled in the art would recognize that the PTD's variations represent predictable extensions of the source patent's core bacterial extract technology. The proposed microfluidic extraction, lyophilization, and personalized treatment approaches are logical refinements that build upon the foundational bacterial extract method for treating sensitive skin. These modifications represent incremental improvements using known techniques within the established technological framework of the original patent.

Obvious Combinations & Variations

Source Patent Element

Bacterial extract from non-pathogenic Gram-negative bacterium with specific 16S rRNA sequence

PTD Variation

Microfluidic extraction method for obtaining bacterial extract

Obviousness Reasoning

Microfluidic extraction is a known technique for improving biological material isolation, offering more precise and efficient extraction compared to traditional methods. A PHOSITA would recognize this as a predictable optimization of extract preparation techniques.

Source Patent Element

Bacterial extract for treating cutaneous neurogenic inflammation

PTD Variation

Combining bacterial extract with anti-inflammatory agent

Obviousness Reasoning

Combining therapeutic agents to enhance treatment efficacy is a standard practice in dermatological formulations. A PHOSITA would find it obvious to augment the original extract's effectiveness by incorporating complementary anti-inflammatory compounds.

Source Patent Element

Method of treating sensitive skin using bacterial extract

PTD Variation

Real-time monitoring system for personalized skin inflammation treatment

Obviousness Reasoning

Personalized medicine and adaptive treatment technologies are well-established approaches. A PHOSITA would recognize the logical extension of creating a responsive treatment system based on individual skin inflammation characteristics.

Source Patent Element

Bacterial extract with specific genetic characteristics

PTD Variation

Lyophilization method for enhancing extract stability

Obviousness Reasoning

Lyophilization is a standard preservation technique for biological materials, offering predictable benefits in extending shelf life and maintaining extract integrity. A PHOSITA would consider this a routine optimization of extract storage methods.

Source Patent Element

Bacterial extract from specific bacterial strain (LMB64)

PTD Variation

Skin type-based extract selection and personalized administration

Obviousness Reasoning

Tailoring medical treatments to individual characteristics is a known approach in personalized medicine. A PHOSITA would find it obvious to develop a systematic method for matching bacterial extracts to specific skin types based on established dermatological principles.

35 U.S.C. § 103 Summary: Pursuant to 35 U.S.C. § 103, the variations disclosed in this publication would have been obvious to a person having ordinary skill in the art at the time of the invention, when considering the teachings of US Patent 11857578. The incremental improvements represent predictable technological extensions that would be readily conceived by a skilled practitioner, thereby rendering potential claims covering similar technical approaches anticipated and non-patentable.
