Research Frontiers Files Patent Infringement Lawsuit Against Amazon, Barnes &
Noble, E Ink and Sony

WOODBURY, N.Y., July 12, 2013 (GLOBE NEWSWIRE) -- Research Frontiers Inc.
(Nasdaq:REFR), the developer and licensor of SPD-Smart light-control
technology has filed a lawsuit against E Ink Corporation; E Ink Holdings, Inc.
(f/k/a Prime View International Co., Ltd.);, Inc.; Sony Electronics
Inc.; Sony Corporation; Barnes & Noble, Inc.; and LLC in
the United States District Court for the District of Delaware for patent
infringement. Research Frontiers seeks an injunction in addition to monetary
damages and pre-judgment interest and other relief.

In this lawsuit, Research Frontiers asserts infringement by the named
defendants of United States Patent No. 6,606,185, entitled "SPD Films and
Light Valves Comprising Liquid Suspensions of Heat-Reflective Particles of
Mixed Metal Oxides and Methods of Making Such Particles," and United States
Patent No. 5,463,491, entitled "Light Valve Employing a Film Comprising an
Encapsulated Liquid Suspension, and Method of Making Such Film."

"A team of scientists and other dedicated individuals have worked for decades
and Research Frontiers has invested approximately $90 million to develop
SPD-Smart light-control technology," noted Joseph M. Harary, President and CEO
of Research Frontiers. "Over 40 companies around the world, including many of
the world's leading chemical and glass companies, have recognized the value of
our intellectual property and entered into license agreements with us. Many of
these companies are using our technology to commercialize products in a number
of industries including the automotive, aircraft, architectural, marine and
museum markets, and these licensees and their customers in turn have built
substantial businesses around our technology and made SPD-Smart light-control
technology the world's best-selling smart window technology. We believe that
it is unfair to us, to our licensees, and to their customers, when companies
infringe upon our intellectual property rights, and we are asking the court to
stop such infringement by the defendants and compensate us with substantial
monetary damages."

Research Frontiers alleges that E Ink's products and those of its customers
such as various models of the Amazon Kindle, Sony Reader, Barnes & Noble Nook,
and other e-reader/e-book devices, infringe on its patents.

Research Frontiers has retained the law firm of Niro, Haller & Niro, a
Chicago-based law firm that specializes in intellectual property litigation,
to prosecute the case. Research Frontiers does not expect its share of the
costs associated with this litigation to be material to its overall operations
because it has entered into a contingency agreement with Niro, Haller & Niro
which greatly reduces its exposure to the costs associated with the
prosecution of this litigation.

Research Frontiers holds several hundred patents and pending patent
applications in the United States and jurisdictions throughout the world.
