TOKYO, Japan and NORMAN, Oklahoma -- April 17, 2002 -- Hitachi, Ltd. (NYSE:HIT/ TSE: 6501) and Hitachi Computer Products (America) Inc., today announced that they filed a patent infringement lawsuit against EMC Corporation in the U.S. District Court for the Western District of Oklahoma. The complaint alleges that certain EMC data storage systems, including products in both EMC's Symmetrix and CLARiiON product lines, infringe eight patents owned by Hitachi, Ltd. and Hitachi Computer Products (America), Inc. The suit also seeks an injunction against the future sale of these EMC products.

Last Thursday, EMC filed infringement litigation against Hitachi, Ltd. and Hitachi Data Systems Corporation at the U.S. International Trade Commission in Washington and in U.S. District Court in Massachusetts, alleging that Hitachi's competitive products infringe six EMC patents.

Isao Ono, Senior Corporate Officer and Senior Group Executive, Information Business Group of Hitachi, Ltd. said: "Since EMC has chosen to compete in the courtroom rather than in the marketplace, Hitachi has no choice but to fight back with its own extensive patent portfolio in this field. Hitachi will hold EMC fully accountable for infringing Hitachi patents."

Hitachi has been providing leading-edge data storage products and services since 1967 and has one of the world's largest R&D programs, which has generated more than 1,200 issued U.S. patents in the data storage field.

Hitachi Computer Products (America) Inc. manufactures data-storage equipment in Norman, Oklahoma.
