RESEARCH FRONTIERS SELLS NEW LICENSE TO AGC FLAT GLASS EUROPE
TO MANUFACTURE AND OFFER SPD-SMART ARCHITECTURAL WINDOWS

WOODBURY, NY, December 17, 2007 - Research Frontiers Inc.
(Nasdaq: REFR) has sold a new license to AGC Flat Glass Europe SA
to offer architectural smart windows using Research Frontiers'
patented SPD-Smart(TM) light-control film. When integrated with
windows, skylights, light tubes, doors, interior partitions and
other products, SPD-Smart film gives users the ability to rapidly,
precisely and uniformly control the amount of light, glare and heat
passing through glass or plastic.

AGC Flat Glass Europe (formerly Glaverbel SA) is the European flat
glass branch of AGC (Asahi Glass Company), the world's largest
glassmaking group. The company is a growth-oriented, customer-focused
company highly regarded globally for its innovative products. The new
non-exclusive worldwide license agreement with AGC Flat Glass Europe,
which renews and replaces Glaverbel's prior license agreement, provides
for a 5-10% royalty payable to Research Frontiers on sales of licensed
products. Other license provisions, including fees and minimum annual
royalties payable to Research Frontiers, were not disclosed.

SPD light-control technology is protected by over 500 patents and patent
applications held by Research Frontiers Inc., the developer and licensor
of the technology to be used in AGC Flat Glass Europe's smart window
products. As well as instant light control benefits, SPD-Smart products
reduce outside noise, provide greater security for both privacy and
structural integrity, and protect interiors and occupants from heat and
harmful ultraviolet radiation.

In addition to being an environmentally friendly "clean technology"
because of its potential daylighting and energy savings advantages,
SPD-Smart windows provide empowering quality-of-life and aesthetic
benefits by offering control over the environment to suit one's
preference. These windows, skylights and other glazings can be optically
clear, block over 99% of visible light, and are tunable manually or
automatically to any level of light transmission between dark and clear.
All of this is done instantly regardless of the window size - advantages
that other competitive smart window technologies, such as liquid crystal
or electrochromics, cannot offer.
