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. 11,857,496.

Summary of the Inventive Concept

A family of temperature-controlled shippers tailored for specific, high-stakes operational environments, including extreme weather conditions, high-security needs, disaster relief situations, and arctic environments.

Background and Problem Solved

The original patent disclosed a temperature-controlled shipper for shipping diagnostic blood sample vials, but it lacked adaptability for unique operational environments. The new inventive concept addresses this limitation by providing specialized shippers that cater to specific niche markets, ensuring temperature-sensitive products remain within a safe temperature range despite challenging environmental conditions.

Detailed Description of the Inventive Concept

The new inventive concept comprises a range of temperature-controlled shippers, each designed for a specific operational environment. For extreme weather conditions, an additional thermal insulation layer is incorporated to maintain a temperature between 6° C. and 37° C. for up to 24 hours. For high-security environments, a GPS tracking device is integrated to monitor the shipper's location and temperature. In disaster relief situations, a method is provided for preparing and transporting the shippers while maintaining a safe temperature range. For arctic environments, a heating element is added to maintain a temperature above -20° C. Finally, a modular system is disclosed, featuring interchangeable thermal insulation layers and GPS tracking devices, allowing for adaptability across various operational environments.

Novelty and Inventive Step

The new inventive concept introduces a range of specialized shippers that adapt the original patent's temperature-controlled shipper to specific niche markets, providing a non-obvious solution to the problem of temperature-sensitive product shipping in challenging environments. The inventive step lies in the combination of the original patent's dual phase change material liquid suspension with novel components and features tailored to each niche market.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the thermal insulation materials, phase change material compositions, and GPS tracking device configurations. Additionally, the modular system could be expanded to accommodate other operational environments, such as desert or tropical regions.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in various industries, including pharmaceuticals, biotechnology, and disaster relief. The specialized shippers can provide a competitive advantage in high-stakes logistics, ensuring the safe transportation of temperature-sensitive products in challenging environments.

Field of Art

Temperature-controlled packaging and transportation of sensitive biological materials, with expertise in thermal engineering, phase change materials, and medical logistics. Requires advanced understanding of thermal insulation, material science, and product preservation techniques.

Person of Ordinary Skill (PHOSITA) Profile

A professional with a degree in materials engineering, packaging science, or biomedical engineering, having 3-5 years of experience in designing temperature-controlled shipping solutions for medical and pharmaceutical applications. Familiar with thermal management strategies, phase change material technologies, and transportation regulatory requirements.

Obviousness Rationale

A PHOSITA would recognize that the PTD represents predictable variations of the source patent's core temperature-controlled shipping technology. The fundamental dual phase change material suspension remains unchanged, with the novel contributions being contextual adaptations for specific environmental challenges. These modifications represent standard engineering problem-solving approaches that would be immediately apparent to a skilled practitioner seeking to extend the original patent's utility.
