Cypress Case Targeting Routers With GSI Chips to Get ITC Review

Cypress Semiconductor Corp. (CY)’s patent claims against GSI Technology Inc. (GSIT) will be reviewed by the U.S. International Trade Commission, in a case that seeks to block imports of routers and switches made by companies including Alcatel-Lucent SA and Motorola Solutions Inc.

Cypress claimed in a June filing that static random-access memory chips produced by GSI infringe four patents, and it sought to prevent the products, as well as devices containing the chips, from being sold in the U.S. The ITC, a Washington- based arbiter of trade disputes, said in a notice today it would investigate, a process that typically takes 15 to 18 months.

The dispute over technology used to store instructions or data targets at least 12 companies including GSI, Alcatel, Motorola, Cisco Systems Inc., Hewlett-Packard Co. and Nokia Oyj’s and Siemens AG’s phone-equipment venture. Arrow Electronics Inc. (ARW), which distributes GSI circuits, was also named by Cypress, a San Jose, California-based maker of chips used in mobile devices.

Cypress also filed a lawsuit against Sunnyvale, California- based GSI in March, alleging infringement of five patents.

The case is In the Matter of Certain Static Random Access Memories and Products Containing Same, 337-792, U.S. International Trade Commission (Washington). The civil suit is Cypress Semiconductor Corp. v. GSI Technology Inc., 11cv789, U.S. District Court for the District of Minnesota (Minneapolis).
