Item 7.01 Regulation FD Disclosure

On May 18, 2010, Research Frontiers Inc., Smart Glass International
Ltd. (SGI) and Schott Group announced the expansion of their
SPD-SmartGlass business internationally as noted in the press
release reproduced below:

SmartGlass International, Schott and Research Frontiers
Announce SPD-Smart License Expansion from the Hamburg Air Show


May 18, 2010-From the booth of its partner the SCHOTT Group at
the 2010 Aircraft Interiors Expo in Hamburg, Germany, SmartGlass
International Ltd., a licensee of Research Frontiers Inc.
(Nasdaq: REFR), announced an agreement with Research Frontiers
to expand the scope of SmartGlass International's license to
include SPD-Smart aircraft and marine products, and a further
expansion of the geographic territory where it can offer these
and its SPD-Smart(tm) architectural products.

Under the new agreement, SmartGlass International is authorized
to manufacture and offer SPD-Smart architectural, aerospace and
marine products worldwide. These products include: architectural
windows, skylights and partitions; aerospace windows and cabin
dividers; and marine windows. Prior to this agreement, SmartGlass
International was licensed to offer SPD-Smart architectural
products worldwide outside of North America.

SmartGlass International is the leading worldwide manufacturer of
electronically switchable glass supplied to the commercial,
hospitality, healthcare, transport and security, industrial,
exhibition and exclusive residential sectors. The company
recently tripled its smart glass production capacity with a
new factory capable of producing over 400,000 square feet of
smart glass per year. This factory, located in Dublin, Ireland,
includes state-of-the-art lamination and glass fabrication facilities.

SmartGlass International and the SCHOTT Group have an agreement
granting SCHOTT the right to sell SmartGlass International's
SPD-Smart products. In business for more than 125 years, SCHOTT is
a world leader in the specialty glass industry and brings its
extensive infrastructure of sales, distribution and service -
including over 50 sales offices spanning 125 countries - to
SmartGlass International and its award-winning SPD-Smart
product line.

The 2010 Aircraft Interiors Expo, considered the leading event
for the world's aircraft interiors industry, will be held
May 18-20, 2010 in Hamburg Germany. SmartGlass International
will exhibit an SPD-Smart aircraft cabin window and other smart
glass products at the SCHOTT Aviation booth located at Stand 5G80.
Information about the Aircraft Interiors expo can be found at:
http://www.aircraftinteriorsexpo.com.

SPD-Smart light-control film technology transforms widely
used products - windows, skylights, curtainwalls, partitions,
sunroofs and more - into products that allow users to instantly
and precisely control the light, glare and heat entering a
building or vehicle. SPD-SmartGlass is instantly tunable to
an infinite number of light transmission states regardless of
window size, and easily adapts to individual preferences using
control devices ranging from basic dimmer switches and
photosensors to those that are integrated into a building's
or vehicle's intelligent control system. These unequalled
performance characteristics help optimize energy-savings and
human comfort, and they offer many other desired benefits
such as increased security, noise reduction, protection from
harmful ultraviolet light and the potential for aesthetically
distinctive designs. On aircraft, weight-saving light-control
and shading systems are needed that reduce cabin heat build-up,
preserve views and offer privacy on-demand, and protect
passengers and interiors from harmful UV light. In a boat,
glare from the water and solar heat gain from the sun can
pose particularly unique issues that need heat, light and
glare to be controlled and managed, while also preserving
views. In a home or office, managing energy and preserving
views is desired using windows and skylights with excellent
solar heat gain control properties and daylight harvesting
benefits to further reduce energy consumption and improve
occupant comfort. SPD-Smart light-control film technology
can address all of these needs, thus allowing elegant and
efficient engineering and design solutions for the modern
green home, office, boat, car or aircraft.

John Browne, Managing Director of SmartGlass International,
commented: "The world market is increasingly demanding
high-performance glazings that share a common set of
performance features and outcomes across applications -
energy efficiency, dynamic shading and privacy on-demand,
enhanced occupant and passenger comfort, and product
solutions that integrate well with automated control
systems. We are committed to offering the best smart
glass products available today and are very excited to
work with our partner SCHOTT to bring an expanded portfolio
of architectural, aerospace and marine SPD-Smart products
to the world market."

"SmartGlass International and their growing business has
an excellent and well-deserved reputation in the worldwide
smart glass industry," commented Joseph Harary, Chief Executive
Officer of Research Frontiers. "They bring many resources and
competencies to the SPD infrastructure and to their customers -
a commitment to product quality and customer service,
world-class production capabilities, and their strong sales and
service partnership with SCHOTT. This expansion further of their
licensed products into aircraft and marine, and their now
worldwide geographic territory will bring the many distinctive
benefits of SPD-Smart products to even more people and
organizations across the world."
