Knowles' MEMS Microphones Infringe Analog Devices' Patent

Analog Devices, Inc.

, a global leader in high-performance semiconductors for signal-processing applications, announced today that the U.S. International Trade Commission (

) ruled decisively in favor of Analog Devices in its lawsuit against Knowles Electronics. Administrative Law Judge Robert K. Rogers, Jr. concluded that Knowles infringes valid claims from one of ADI's Wafer Anti-Stiction Application (WASA) patents. Specifically, he ruled that Knowles infringes claims 2, 3, 4, 5, 6 and 8 from ADI's U.S. Pat. No. 7,364,942. As a result, ADI expects the ITC to issue an exclusion order prohibiting Knowles and its U.S. Distributor from importing or selling all infringing microphones in the United States. Additionally, ADI expects to recover damages on all past sales of Knowles' microphones through its pending lawsuit against Knowles in Delaware.
