Mitsubishi Files Patent Infringement Complaint Against SanDisk Subsidiary In Japan

Apr 2, 2000

SUNNYVALE, CA, April 2, 2000 - SanDisk Corporation (NASDAQ:SNDK) announced today that Mitsubishi Denki Co. Ltd. (Mitsubishi Electric) has filed a complaint in Tokyo District Court against SanDisk K.K., SanDisk's wholly-owned subsidiary in Japan. The complaint alleges that SanDisk K.K., based in Yokohama, Japan, infringes on three Mitsubishi Japanese patents. In the complaint, Mitsubishi asked the court for a preliminary injunction halting the sale of SanDisk CompactFlash™ and flash ATA™ memory cards in Japan.

Eli Harari, CEO and president of SanDisk Corp., said, "SanDisk has been engaged in patent cross-license discussions with Mitsubishi Electric. We believe that Mitsubishi Electric's latest action is intended to secure for them a cross-license for our valuable portfolio of patents. We intend to vigorously defend our intellectual property rights."

The Mitsubishi patents in question are #JP2099342, #JP2129071 and #JP2138047. Based on preliminary information, SanDisk believes that these patents are related primarily to the mechanical construction of memory cards built with a separate connector.

SanDisk Corporation, the world's largest supplier of flash data storage products, designs, manufactures and markets industry-standard, solid-state data, digital imaging and audio storage products using its patented, high density flash memory and controller technology. SanDisk is based in Sunnyvale, CA.
