Tessera Acquires Intellectual Property Rights from Kronos Advanced Technologies

SAN JOSE, Calif. AND BELMONT, Mass -- April 3, 2008 -- Tessera Technologies, Inc. (Nasdaq: TSRA), a leading provider of miniaturization technologies for the electronics industry, and Kronos Advanced Technologies, Inc. (OTCBB: KNOS), a leading developer of ionic-based products and technologies for air movement and purification, today announced the sale and licensing of certain intellectual property (IP) rights related to Kronos proprietary technologies to Tessera.

Kronos received $3.5 million from Tessera in exchange for the transfer of select Kronos patents covering micro-cooling applications. Kronos retains the rights to use these patents for applications outside of the field of micro-cooling. Tessera further has the right to acquire additional Kronos IP relating to micro-cooling applications, and the two companies have the option to continue to jointly develop new technologies in this field.

"The continued increase in the density of electronics has resulted in a growing demand for innovative ways to more effectively dissipate heat from electronic systems,” said Daniel Dwight, president and chief executive officer of Kronos. “This agreement provides a significant validation of Kronos’ technical expertise, while providing Tessera with the ability to further develop and commercialize this technology for a wide range of applications."

“Thermal management is a key area for the electronics industry, as well as a key aspect of miniaturization, and we are developing break-through thermal management solutions that target

this space,” said Bruce McWilliams, president, chairman and chief executive officer of Tessera. “We look forward to collaborating with Kronos to build on what we believe is the earliest and most significant IP in this space.”
