International Trade Commission Sets Date for Investigation of Analogic Tech for Infringement of Linear Technology Patents

May 23, 2006

    MILPITAS, Calif., May 23 /PRNewswire/ -- Linear
Technology Corporation (Nasdaq: LLTC), a leading
manufacturer and supplier of patented high-performance
analog integrated circuits, announced today that the United
States International Trade Commission (ITC) has set the date
for completion of the investigation into whether Advanced
Analogic Technologies (AnalogicTech) is violating Section
337 of the U.S. Tariff Act.  The ITC investigation stems
from a complaint filed with the ITC by Linear Technology on
February 17, 2006, asserting that AnalogicTech's power
management ICs infringe various claims of Linear's U.S.
Patent Nos. 6,411,531 and 6,580,258. The Administrative Law
Judge (ALJ) assigned to the investigation at the ITC has set
a target date of February 22, 2007 for the initial
determination concerning violation of section 337, and
ruled that the investigation must be completed by May 22,
2007.

    If the ITC determines that AnalogicTech's power
management ICs infringe Linear Technology's patents and
that their products are imported into the United States,
the ITC may order such products to be completely excluded
from the U.S. market. The ITC can also impose civil
penalties of up to $100,000 (U.S.) per day in the event
that AnalogicTech does not comply with its orders.

    The ITC is an independent, nonpartisan, quasi-judicial
federal agency that provides trade expertise to both the
legislative and executive branches of government,
determines the impact of imports on U.S. industries, and
directs actions against certain unfair trade practices,
such as patent, trademark and copyright infringement and
other illegal acts of importation into the United States.
