Lexar Files ITC Complaint Against Toshiba

FREMONT, Calif., Apr 11, 2006 -- Lexar Media, Inc. (Nasdaq:LEXR), a world leader in advanced digital media technologies, today officially filed a formal complaint with the International Trade Commission (ITC) against Toshiba Corporation, Toshiba America, Inc., and Toshiba America Electronic Components, Inc. seeking to halt the infringement of Lexar's intellectual property rights.

In this complaint, Lexar asserts that Toshiba's chips and flash cards, including among others, Toshiba's 16-gigabit multi-level cell NAND flash chips, Toshiba's 8-gigabit single level cell and multi-level cell NAND flash chips, Toshiba's 4-gigabit multi-level cell NAND flash chips and Toshiba's 1-gigabit single level cell NAND flash chips, infringe Lexar's United States Patent Nos. 6,801,979; 6,397,314; and 6,978,342.

With this filing, Lexar requests that the ITC institute an immediate investigation against Toshiba based on the importation of the infringing NAND flash chips and flash cards. While the ITC can not assess damages against an infringer, it can issue an exclusion order prohibiting the importation of infringing technology. Lexar has asked the ITC to grant all possible relief, including an exclusionary order, enforceable by U.S. Customs, prohibiting the importation into the United States of Toshiba's chips and cards as well as products that contain Toshiba's NAND chips. Further, Lexar has asked the ITC to issue a cease-and-desist order which could require retailers and distributors to remove from their shelves and destroy all products containing Toshiba's infringing NAND chips. If the complaint is accepted by the ITC, the ITC will institute a formal Section 337 investigation within 30 days.

Certain of the patented technology at issue in this complaint is related to the technology that a jury, after a six-week trial in March 2005, found that Toshiba had misappropriated from Lexar. That case is now on appeal.

The ITC is a federal agency that provides objective 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.
