Pasadena, CA, March 12, 2025 — DTP Thermoelectrics has been granted a European Unitary Patent for its groundbreaking thermoelectric technology. This marks the fourth international patent awarded for this innovation, now extending patent protection to regions covering approximately one-third of the world’s population, including much of the industrialized world.
The patent, "Thermoelectric Elements and Devices With Enhanced Maximum Temperature Differences Based on Spatially Varying Distributed Transport Properties" (EP 3918645), issued by the European Patent Office, protects DTP’s unique approach to enhancing cooling and heating performance in thermoelectric devices.
Our technology builds on rigorous theoretical and analytical models, which we have tested extensively by fabricating and evaluating thermoelectric devices using Distributed Transport Properties (DTP) materials.
DTP Thermoelectrics was awarded a U.S. National Science Foundation (NSF) Small Business Innovation Research (SBIR) grant to accelerate the development and commercialization of our breakthrough technology.
Standardized testing protocols demonstrate significant gains in cooling capacity, efficiency (COP), and maximum cooling temperature. These results prove that DTP devices achieve at least 10°C lower temperatures while delivering greater cooling capacity and higher operating efficiency, outperforming conventional thermoelectric systems.
Previously, such cooling performance was only achievable with larger, heavier mechanical cooling systems. DTP technology is paving the way for more compact, efficient, and high-performance thermoelectric solutions.
