Item 7.01 Regulation FD Disclosure

Research Frontiers Licensee Isoclima to
Exhibit Its Cromalite Brand
of SPD-SmartGlass at Vitrum 2009

On October 27, 2009, it was announced that Isoclima S.p.A.,
a licensee of Research Frontiers Inc. (Nasdaq: REFR) will
exhibit its Cromalite(R) brand of SPD-SmartGlass(tm) at
Vitrum 2009 being held from October 28-31, 2009 at the
Fiera Milano Complex in Rho, Italy.

Vitrum 2009 is the international trade fair for machinery,
equipment and systems for the processing of flat glass,
hollow glass, and finished glass products. The most recent
Vitrum trade fair in 2007 attracted more than 17,000 visitors
from across the world. More information about Vitrum 2009 can
be found at www.vitrum-milano.it.

Isoclima will feature a prototype back window for a luxury vehicle
made with its Cromalite brand of SPD-SmartGlass. The large back
window measures 1.4 by 0.85 meters (55 x 33 inches), is curved, and
has a range of visible light transmission of approximately 1% to 50%.

'The Cromalite glass panels of today are much stronger and more
durable than the Cromalite made by our company even just a year
ago,' commented Dr. Alberto Bertolini, General Director of Isoclima.
'In addition to our work with customers in the automotive and marine
markets, we are beginning now to offer Cromalite for architectural
smart glass projects as well.'

Isoclima will exhibit Cromalite and other products at its booth
located in Pavilion 15, Stand K01. More information about Isoclima
can be found at www.isoclima.net.

SPD-Smart? products use patented SPD film technology developed by
Research Frontiers. With the touch of a button or turn of a dial,
users can instantly and precisely adjust the tint of windows,
sunroofs, glass roof systems, skylights and other products.
Automated adjustment of SPD-Smart products also is available
using sensors or timing devices. SPD films can be combined with
other glazing materials, such as materials used in armored glass,
to meet a wide range of end-product requirements across many
applications.
