U.S. International Trade Commission Judge Rules in Favor of Knowles in Trade Secret Theft Case Against Bellsing

Chief Judge Recommends 26-Year Import Ban of Offending Bellsing Devices and Any Products Containing Them

Knowles Corporation (NYSE: KN), a market leader and global provider of advanced micro-acoustic microphones and speakers, audio processing, and precision device solutions, today announced that ITC Chief Administrative Law Judge Charles E. Bullock issued an Initial Determination (ID) in ITC Investigation No. 337-TA-1186 finding that the Chinese electro-acoustic transducer manufacturer Shenzhen Bellsing Acoustic Technology Co., Ltd, its affiliated companies and its founder, Liang (Ryan) Li, misappropriated Knowles’ trade secrets in violation of Section 337 of the Tariff Act of 1930. In a 129-page decision, the Chief Judge found that Bellsing’s and Li’s “use of Knowles’ trade secrets is extensive” and that Bellsing relies on misappropriated Knowles trade secrets to design and manufacture balanced armature (BA) devices.

"We are pleased with Chief Judge Bullock’s ID acknowledging that Bellsing balanced armature devices utilize technology stolen from Knowles. Knowles has a long history of significant investment in R&D and new innovative products and we will vigorously protect our intellectual property,” said Jeffrey Niew, president and chief executive officer of Knowles.

Chief Judge Bullock’s ID recommended two significant remedies in favor of Knowles, including imposing a 26-year long general exclusion order barring the importation into the United States of Bellsing balanced armature devices that are made with, use, or benefit from Knowles’ trade secrets, as well as any downstream products, regardless of source, containing the offending Bellsing devices, such as hearing aids and wireless headsets. This would include BA devices made by or made for companies owned by, controlled by, or affiliated with Ryan Li. The Chief Judge also recommended a complementary cease and desist order barring Bellsing and Mr. Li from, among other things, making further sales of the offending Bellsing devices for importation into or within the United States.

“Given Bellsing’s blatant disregard for our intellectual property and history of unfair acts in connection with the use of our balanced armature technology, we believe the remedies recommended by the Chief Judge are appropriate,” said Robert Perna, senior vice president and general counsel for Knowles.

Chief Judge Bullock’s ID and recommendation on remedies are subject to review by the ITC, and a final determination by the ITC is expected in the next several months.
