Cirrus Logic and Wolfson Microelectronics Settle Litigation

(I-Newswire) March 25, 2005 - In October 2003, Cirrus Logic brought suit against Wolfson Microelectronics plc and its subsidiary Wolfson Microelectronics, Inc. in the U.S. District Court in San Diego for patent infringement. Cirrus Logic subsequently initiated an investigation by the United States International Trade Commission (ITC), which terminated in February 2005.

Under a settlement agreement, the parties have agreed to withdraw all outstanding claims and counterclaims in the U.S. District Court proceedings. An application is being made to the ITC for the withdrawal of the exclusion order that the ITC issued in February 2005 in relation to one of the Cirrus Logic patents.

The terms of the settlement are confidential.
