Round Rock Research LLC to Offer at Auction Four 'Covenants not to Sue' Covering Its Portfolio of Approximately 4,200 Patents and Pending Applications

NEW YORK, March 9, 2011 - ICAP Ocean Tomo (www.icapoceantomo.com) - the global intellectual
property brokerage firm - will be auctioning four "Covenants not to Sue" at
its Spring 2011 Live IP Auction event on March 31st in New York City. Each
covenant provides a purchaser with the freedom to operate in a specific
field. At a time when IP considerations are becoming more important and more
complex, a covenant may well be on its way to becoming one of the key
instruments in an IP portfolio.

Offered by specific sellers and covering specific portfolios, a covenant
provides high tech firms with increased freedom to operate in an efficient
and expeditious manner without the worry of showing one's hand when
negotiating with a Licensor, either directly or through a proxy, and avoids
potential patent infringement claims, damages, or attorneys' fees.

Originally developed by Micron Technologies, Round Rock Research's
portfolio of approximately 4,200 patents and pending applications spans the
United States, and much of Europe and Asia, encompassing key technologies
including:

    -- Battery and power;
    -- CMOS imagers;
    -- Computers;
    -- Computer graphics;
    -- Computer networks;
    -- Display technology;
    -- DRAM;
    -- Flash;
    -- Memory;
    -- Microprocessors;
    -- O/S software;
    -- Ovonics;
    -- Semiconductor packaging;
    -- Semiconductor processing;
    -- RFID; and
    -- Telecommunications

Current licensees of the Round Rock portfolio include Apple, Sony,
Samsung, Micron and Nokia. Each of the four covenants available at auction is
applicable to a subset of the buying community, and provides potential
purchasers with a quick and effortless means to obtain freedom to operate
that is both wide ranging and comprehensive. For additional information on
this opportunity please contact Dean Becker at +1-561-309-0011.

"We are currently litigating these patents, and are pursuing other
infringers of the portfolio," said John Desmarais of Round Rock Research LLC.

acquire a covenant and avoid future litigation."
