ClearOne files patent infringement suit against Shure, Biamp and QSC
As first reported by Lindsey Adler in SCN, ClearOne, a global provider of audio and visual communication solutions, has been awarded a patent on a system and method for combining echo cancellation and beamforming microphone arrays. Following this, the company moved to file suit for infringement against Shure, Biamp, and QSC, as collective defendants.

ClearOne first developed its beamforming microphone conferencing system in 2010, according to the company, designed to replace up to a dozen individual mics with a small beamforming array. The Beamforming Microphone Array audio conferencing system was brought to market in 2012, combining beamforming, AEC, and adaptive steering. The second generation was introduced in June 2016, operating on new peripheral bus architecture, allowing it to connect with ClearOne’s Converge Pro 2 DSP mixers.

The U.S. patent (No. 9,635,186), entitled “Conferencing Apparatus that Combines a Beamforming Microphone Array with an Acoustic Echo Canceller,” was issued 25 April 2017. The subsequent legal complaint was also filed 25 April.

At ISE 2016, Shure debuted the Microflex Advance portfolio of networked ceiling and table array microphones, audio interfaces, and control software for conferencing. The MicroFlex Array includes steerable coverage, enabling up to eight lobes of pickup, configurable in three dimensions. The solution began shipping in August 2016.

Biamp and Shure created an integrated compatibility between Biamp’s Tesira audio processors and software to support Shure’s MicroFlex advance solutions. QSC has partnered with Shure to integrate the Q-SYS Platform with the Microflex Advance.

ClearOne is seeking injunctive relief, meaning Shure, QSC, and Biamp would need to stop selling and promoting these products. Once a motion for injunction is filed, a judge would need to rule.

Alexander C.D. Giza, of Hueston Hennigan LLP, the firm representing ClearOne, stated: “ClearOne and its inventors and engineers have invested millions of dollars and hours of effort in research and development on this important technology. As a result, they manufacture industry-leading beamforming and acoustic echo cancellation audio conferencing systems. And as of Tuesday, they have a US patent on this invention. ClearOne is entitled to have its patent and innovation respected by the industry.”

Mark Brunner, Shure, VP of global, corporate, and government relations, confirmed that Shure received the allegations. Shure strongly believes the allegations are without merit, and they intend to defend themselves in the matter. While it’s Shure’s policy not to comment on ongoing legal cases, he said that Shure has initiated litigation to defend Shure’s rights and products.

Amanda Roe, Biamp, global public relations manager, told SCN: “We are aware of the lawsuit and are currently analysing the matter in order to respond accordingly.”
