Spansion Files Two Additional Patent Infringement Complaints Against Macronix

Last Updated: April 29, 2014

SUNNYVALE, Calif., April 29, 2014 -- Spansion Inc. (NYSE: CODE), a global leader in embedded systems solutions, today announced that it has filed two additional patent infringement complaints against Macronix to address Macronix's past and ongoing widespread violations of Spansion's patents in a broad and growing range of Macronix NOR Flash and XtraROM memory products. Spansion filed its new complaints with the U.S. International Trade Commission (ITC) and the United States District Court for the Northern District of California.

The four patents asserted relate to the manufacturing, structure and use of non-volatile memory chips. These additional complaints follow ITC and District Court complaints Spansion filed in August 2013. 

Non-volatile memory is a critical part of billions of dollars worth of consumer electronics such as cartridges for gaming devices, digital cameras, networking equipment, set-top-boxes, and notebook and tablet computers. Spansion has invested billions of dollars in research and development and holds more than 5,000 patents and patent applications. The patents in the suits represent only a small portion of Spansion's IP portfolio.

Spansion's ITC complaint seeks to exclude infringing Macronix non-volatile memory devices and all downstream products containing such Macronix memory devices from the US market. While Macronix is the subject of these litigations, Spansion also named some manufacturers of downstream products containing Macronix infringing devices in its ITC complaint, consistent with current ITC procedures.
