Cypress expands patent infringement complaint vs. GSI Technology to include synchronous, ZBT and proprietary SRAM products

SAN JOSE, USA: Cypress Semiconductor Corp. reported that as a result of the discovery phase of its litigation with GSI, the accused products list was expanded in the ongoing ITC action to include GSI’s standard Synchronous and ZBT SRAMs. In addition, in a filing with the International Trade Commission (ITC) on Nov 21, 2011, a proprietary product made by GSI for its largest customer was also added to the suit.

The new additions to the ITC action were added to the original complaint filed with the ITC in June 2011, which also alleges infringement by GSI’s SigmaQuad-II, SigmaQuad-III and SigmaDDR SRAM families of four Cypress SRAM patents. The Cypress complaint seeks an exclusion order from the ITC that would prevent the importation of all infringing GSI SRAMs.

In recent weeks, Cypress has released from its ITC action several companies originally named as importers of GSI memory products incorporated into their products. These companies have agreed to terms acceptable to Cypress with respect to ending the importation of the products named in the ITC.

“We continue to seek an immediate end to the importation of GSI products that infringe on Cypress’s intellectual property,” said Dana Nazarian, executive VP of Cypress’s Memory Products Division. “The ITC trial is on schedule for March, and we expect to prevail.”
