What this patent covers
A thermal insulation shield built from metamaterial — rotated, repeating layers of contrasting materials — arranged so that heat is steered around the protected area rather than simply slowed on its way through. The patent describes using thermal cloaking and heat-flux rotation to get more insulating performance out of the same thickness of material.
US 12,637,856 is a utility patent titled “Meta Material Thermal Shield”, invented by Gopal Prasad Mathur.
The application was filed on October 29, 2025 and granted on May 26, 2026, 6 months later.
It is one of the patents our firm has obtained in the Construction area. The attorney of record printed on the granted patent is Michael J. Feigin, Esq.
Key dates and patent term

Abstract
A meta material anisotropic, thermal insulation shield, designed to significantly improve performance of the thermal insulation by controlling path of heat flux passing through the system. Meta material techniques to enhance the thermal performance of insulating materials using thermal cloaking and/or heat flux rotation are disclosed. Meta material thermal insulating shield is implemented using anisotropic thermal insulation system comprising of rotated periodic layers of contrasting materials and thermal cloaks. Meta material insulation system can provide a system with thermal conductivity, which is much lower than the traditional systems. In other words, a meta material thermal insulation system having a much lower U-value than a traditional thermal insulation system can be designed.
