Research Frontiers develops and licenses patented Suspended Particle Device (SPD-Smart) light-control technology that enables electronic control of light, glare, and heat transmission through windows, skylights, sunroofs, and other glazing applications. The company generates revenue by licensing its technology to manufacturers serving automotive, aerospace, architectural, marine, and display product markets, typically receiving royalties of 10–15% on net sales of licensed end-products plus licensing fees and minimum annual royalties. Rather than manufacturing finished products itself, Research Frontiers maintains a lean operation focused on technology development, licensing, marketing, and administration, leveraging hundreds of patents worldwide to protect its SPD technology against competitors using alternative smart glass approaches like electrochromic or liquid crystal systems.
