Item 7.01 Regulation FD Disclosure

On February 7, 2011, it was announced that Research Frontiers Inc. has
provided the techology for Mercedes-Benz new Magic Sky Control
SPD-SmartGlass roof, as noted in the press release reproduced below:


       RESEARCH FRONTIERS PROVIDES TECHNOLOGY FOR
  MERCEDES-BENZ' NEW MAGIC SKY CONTROL SPD-SMARTGLASS ROOF

Mercedes-Benz SLK debuting in early 2011 will be the first
large-scale series production vehicle to offer SPD-SmartGlass

Woodbury, New York and Sindelfingen, Germany - February 7, 2011. After
evaluating various technologies, Daimler AG selected Research Frontiers'
patented SPD-Smart light-control technology for one of its latest
Mercedes-Benz innovations: the MAGIC SKY CONTROL panoramic glass roof.
The MAGIC SKY CONTROL feature allows drivers and passengers to change
the tint of their car roof from dark to clear instantly with the press
of a button. The first Mercedes-Benz vehicle model to offer the
MAGIC SKY CONTROL glass roof as an option will be the new Mercedes-Benz
SLK which debuted on January 29, 2011.

Nanoparticles suspended in a film manufactured by Hitachi Chemical
Company under license from Research Frontiers allow users to control,
automatically or with the push of a button, the tint from between very
dark (blocking over 99.5% of visible light, which is about 50-60 times
darker than a typical sunroof) to about twice as clear as an ordinary
sunroof.  The new Mercedes-Benz SLK will be the first large-scale
series production vehicle to use Research Frontiers' patented
SPD-Smart light-control technology.

Mercedes-Benz put the MAGIC SKY CONTROL SPD-SmartGlass roof through
rigorous durability and performance testing in some of the most extreme
conditions on earth. This included testing in the arctic cold of
Scandinavia (with temperatures below -22 degrees F/-30 degress C)
and the blistering desert heat of Death Valley, California (with
temperatures exceeding 122 degrees F/50 degrees C).

The MAGIC SKY CONTROL feature using SPD-Smart light-control technology
allows drivers many benefits including the ability to create the
open-air feeling of a roadster even when the weather does not permit
one to open the roof. It also blocks over 99% of harmful UV radiation
and substantially reduces heat inside the vehicle. Test data published
by Mercedes-Benz shows the ability of the roof to reduce sun exposure
to 1/20th of direct exposure levels (from over 1,000 watts/square meter
to less than 50 watts/square meter). When compared to conventional
automotive glass, Mercedes-Benz reported that the use of SPD-SmartGlass
significantly reduces the temperature inside the vehicle by up to
18 degrees F/10 degrees C. This increases passenger comfort and reduces
air conditioning loads, thereby saving fuel and reducing CO2 emissions.

Research Frontiers holds about 500 patents and patent applications
worldwide on its SPD-Smart light-control technology, and licenses it
to 39 companies, including most of the world's leading automotive
glass manufacturers.

Joseph M. Harary, President and CEO of Research Frontiers noted:
"Research Frontiers has invested over $80 million to develop SPD-Smart
light-control technology. This has allowed Daimler AG and its
Mercedes-Benz brand to take the lead to be the first car manufacturer
to offer its customers the most advanced and highest-performing smart
glass in the world. The Mercedes-Benz development team spearheaded a
coordinated effort across three continents among Research Frontiers
and our licensees."

The Research Frontiers licensees involved with the production of the
MAGIC SKY CONTROL roof for the SLK include Hitachi Chemical, which
manufactures the SPD-Smart light-control film in Japan and has recently
announced its capacity to manufacture 4.3 million square feet of SPD film
per year. Automotive glass companies Nippon Sheet Glass in Japan and
Pilkington in the UK and Germany then process and laminate Hitachi's SPD
film into the glass for the MAGIC SKY CONTROL roof. SPD Control Systems
and Research Frontiers have jointly licensed intellectual property to
Daimler AG regarding the electronics to control the SPD-SmartGlass
in the Mercedes-Benz SLK and other vehicles.
