Toshiba Seeks Remedies for Infringement of Essential DVD Patents in U.S. Through Complaints to the ITC and in Federal District Court

Toshiba Corporation announced today that on April 6, 2007, Toshiba
and Toshiba America Consumer Products, L.L.C. filed a formal complaint
with the International Trade Commission (ITC) against 17 manufacturers
and importers of DVD players, DVD recorders and other DVD-related
products, as a means to halt infringement of Toshiba's DVD patents.
Toshiba's filing requests that the ITC prohibit the importation into
the United States of DVD players, DVD recorders and other DVD-related
products by the companies named in the complaint. In a related move,
Toshiba also filed suit in the United States District Court for the
Northern District of California on the same day, seeking damages
resulting from infringement of Toshiba's DVD patents by the same 17
companies.

Toshiba licenses patents essential for meeting DVD format
specifications.(1) The 17 companies named in the complaint and the
lawsuit do not have license agreements with Toshiba or the DVD6C
Licensing Group(2), and have engaged in the importation and sale of
DVD products without permission. The infringement of Toshiba's patents
by these companies has damaged Toshiba's DVD-related business, and
also caused damage to the legitimate and licensed DVD product
manufacturing and distribution business as a whole. Through the filing
of the ITC complaint and the district court lawsuit, Toshiba seeks to
exclude infringing imports, recover monetary damages, and secure
agreements to respect Toshiba's intellectual property rights in the
future.

(1) DVD format specifications are standards adopted by the DVD
Forum.

(2) The DVD6C Licensing Group (DVD6C) is an industry body
representing nine leading developers of DVD technology and formats
that licenses essential DVD patents. For further information on the
