Analog triumphs over Knowles’ MEMS mikes - Analog Devices

Signal processing giant Analog Devices said that the International Trade Association (ITC) has ruled in its favour in a complaint brought against Knowles Electronics.

A judge ruled that Knowles infringed several claims from its patent 7,364,942 relating to its wafer anti-stiction patents.

The ITC, said Analog, will issue an exclusion order banning Knowles and its channel from importing and selling microphones in the USA. As well as complaining to the ITC, Analog also has a civil lawsuit pending against Knowles in the state of Delaware.

Analog said that Knowles claims on patents relating to MEMS microphone packaging patents were rejected by the US Patent and Trademark Office.

Knowles had nothing to say on the matter.
