International Trade Commission Orders Investigation of AnalogicTech for Infringement of Linear Technology Patents

International Trade Commission Orders Investigation of AnalogicTech for Infringement of Linear Technology Patents

March 27, 2006

    MILPITAS, Calif., March 27 /Xinhua-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 instituted
an investigation into whether Advanced Analogic
Technologies (AnalogicTech) is violating Section 337 of the
U.S. Tariff Act.  The ITC investigations stems from a
complaint filed by Linear on February 17, 2006, with the
ITC asserting that AnalogicTech's power management ICs
infringe various claims of Linear's U.S. Patent Nos.
6,411,531 and 6,580,258.

    "We are gratified that the ITC has ordered an
investigation into AATI's activities.  We are confident
that the ITC will conclude that AnalogicTech has infringed
Linear Technology's intellectual property," stated
John England Jr., counsel for Linear.

    If the ITC determines that AnalogicTech's power
management ICs infringe Linear Technology's patents and the
products are being imported into the United States, the ITC
may order that such products 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.
