Approval of Patent Boosts Value of MY DRIVER SEAT



BOCA RATON, Fla., May 2 /PRNewswire-FirstCall/—NuState Energy
Holdings, Inc. (OTC Bulletin Board: NSEH), and Rentar Environmental
Solutions, Inc. (a privately-held company headquartered in Wellington, FL)
announced today that notice of approval had been received from the USPTO
for the patent on the supply chain software that is the basis for the
blockbuster MY DRIVER SEAT application—one of the two major components
of their recently announced RENTAR LOGIC package. This bundle of The Rentar
Fuel Catalyst with MY DRIVER SEAT is the first product of its kind in the
world. MY DRIVER SEAT is a potent fleet management tool which gathers data
in real time and provides timely, concise reports that present a precise
picture of speed, miles per gallon, idling time, out of route, unauthorized
usage, and a great deal of other valuable information. These reports can be
tailored to meet the differing, unique requirements of varied users.
Simultaneously, the reports provide real time data which verifies the
ongoing efficacy of The Rentar Fuel Catalyst, which reduces fuel
consumption up to 12% and significantly lowers harmful emissions. The
Rentar Fuel Catalyst is the holder of six domestic patents and 20
international patents. Frank Reilly, the CEO of NuState, and one of the
guiding forces behind the new venture said, “This new patent gives our
product greater protection. The combination of these two technologies
creates an unparalleled package that gives fleet managers, and other
interested parties, the ability to save money directly on fuel while
dramatically increasing efficiency at the same time. In addition, the
package enables the user to significantly reduce greenhouse gas emissions
and provide clear verification of these reductions.”
