Item 7.01 Regulation FD Disclosure


On March 31, 2009, Research Frontiers Inc. licensee InspecTech Aero
Service Exhibited at the Aircraft Interiors Expo in Hamburg, Germany
SPD-Smart electronic window shades using Research Frontiers' patented
suspended particle device (SPD) light-control film technology. These
shades, which allow users to control the amount of light and glare
coming into the aircraft cabin, are reported to be currently
flying on various aircraft including Qantas' Airbus A380. In their
February 2009 issue, Travel and Leisure magazine described these
windows that give passengers and flight crews more control over
their cabin environment as follows:

"The most extravagant detail of all, however, isn't in the first-class
cabin itself, but in its bathrooms. They are large, with an expansive
sink and counter, and there's a window. When you walk in, the
window... appears to be translucent... When you lock the door it
transforms, as if by magic, into a transparent surface."

More details (the text of which is included herewith as an exhibit)
were provided on April 1, 2008 on Research  Frontiers
www.SmartGlass.com website.
