Founded in 2005, SPD Control Systems Corporation built its identity around the electronics behind Research Frontiers’ SPD smart glass rather than the glass itself. The company developed patented control technology for smart windows used in vehicles and buildings, and its automotive intellectual property was licensed by Daimler AG for Mercedes-Benz vehicles. A 2021 notice reported that the company filed for dissolution after transferring its patent portfolio, with its officers continuing to provide consulting on SPD controls.
