Item 1.01. Entry into a Material Definitive Agreement.

On September 15, 2009 at the Frankfurt International Motor Show,
Pilkington Group Limited announced that it has acquired a new
license from Research Frontiers Inc. (Nasdaq:REFR) to offer
SPD-Smart automotive end-products globally. Research Frontiers
is the developer and licensor of patented VaryFast
SPD-Smart  light-control film technology.

This license represents a significant expansion of Pilkington's SPD
business. In 2004, Pilkington acquired a license from Research
Frontiers to work with SPD technology to make laminated
SPD-SmartGlass panels. During this development phase, Pilkington
gained lamination expertise and also worked extensively with
customers to co-develop SPD-Smart products that meet the needs
and specifications of the automotive industry. With this new license,
Pilkington now has the ability to offer SPD-Smart end-products
including sunroofs, glass roof panels, adaptive sunvisors
incorporated into a vehicle's windscreen, and side and rear
windows.

SPD-Smart automotive products are instantly tunable manually or
automatically to any level of light transmission between clear and
extremely dark - blocking more than 99.5% of incoming visible
light. Due to its ability to block heat as well as visible light,
SPD-SmartGlass can reduce vehicle interior heat build-up and thus
cooling requirements. These eco-friendly products could also reduce
the size of air conditioning systems and thus save weight, fuel and
reduce CO2 emissions. Also, because they are in the most energy
efficient state when the engine is off, the vehicle is cooler upon
entering.

In addition to light, glare and heat control, SPD-Smart automotive
products provide greater security due to their on-demand privacy
capability, and protect passengers and interiors from harmful
ultraviolet radiation. Award-winning SPD-Smart technology offers
exceptionally innovative design opportunities and empowers users
by providing rapid, real-time control over the environment to suit
one's preference or requirements.

The worldwide non-exclusive license grants Pilkington the right to
manufacture and sell SPD-Smart automotive glass products
globally. As part of the NSG Group, Pilkington is one of the world's
leading manufacturers of glass and glazing systems.

Speaking from the floor of the Frankfurt Motor Show, Joseph M.
Harary, President and Chief Executive Officer of Research Frontiers
Inc., noted: "Pilkington and their parent company, NSG Group, are
among the most successful glass companies in the world, and have
considerable experience in all types of high-end and functional glass
products, including smart glass. They have a long and stellar history
of bringing new and practical innovations to the glass industry and
to their customers. Research Frontiers has invested over $75 million
to develop high-performance light control with our SPD-Smart film
technology. With Pilkington's addition to our extensive list of
licensees around the world, Research Frontiers' patented
SPD-Smart light-control technology has now been licensed to
virtually every major glass company in the world for the production
of environmentally-friendly end-products."

"Our SPD teams in the UK, Germany, Japan and the US have been
working closely and intensely with Research Frontiers and our lead
OEM customer to introduce SPD-Smart end-products to the global
automotive market," commented Anthony R. Shaw, Vice President
Technology   Automotive for Pilkington. "SPD technology is a
high-performing technology that offers many distinctive
performance, safety, comfort and energy-saving benefits desired by
OEMs and their customers. We see exciting opportunities ahead in
the very near future."

The worldwide license provides for a 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.

does not purport to be complete and is qualified in its entirety by reference
