SAN FRANCISCO—A U.S. International Trade Commission (ITC) administrative law judge ruled that Knowles Electronics LLC infringes valid claims from a wafer anti-stiction application patent held by Analog Devices Inc. (ADI).
Administrative Law Judge Robert K. Rogers ruled that Knowles infringes six claims from ADI's U.S. Pat. No. 7,364,942, ADI said. As a result, ADI said it expects the ITC to issue an exclusion order prohibiting Knowles and its U.S. distributor from importing or selling all infringing microphones in the U.S. ADI said it also expects to recover damages on all past sales of Knowles’ microphones through its pending lawsuit against Knowles in Delaware.
Knowles issued a statement saying the ITC ruling would not impact its ability to import its products into the U.S. The ruling affects only one of several manufacturing methods that Knowles uses, the company said. "The use of anti-stiction coatings is common in the industry and Knowles uses various anti-stiction coatings and methods in the manufacture of its technology-leading microphone packages," the statement said.
Jeff Niew, president of Knowles Electronics, said the company was disappointed with the ruling and would seek further review from the ITC.
