Last week, Sonos filed a patent-infringement lawsuit against D+M Group over the Heos wireless multiroom-audio system launched earlier this year by Denon. Today, D+M Group responded. 

The company announced that it will protect itself against the patent infringement complaint filed on October 21, 2014, by Sonos. “D+M has been a technology innovator for over 100 years and has an extensive intellectual property portfolio to protect our products. Given our experience and wealth of expertise, we absolutely stand behind our HEOS products and technology and are well prepared to defend our intellectual property,” said Jim Caudill, CEO of D+M Group. “We are an innovative company, constantly seeking to create the best products in the marketplace.” 


According to a press release from the company, Denon's engineers and designers worked for more than ten years to develop HEOS by Denon. 

Introduced in June, 2014, to date the HEOS by Denon product line includes three wireless multi-zone music players: HEOS 3, HEOS 5, and HEOS 7, a HEOS Amp, HEOS Link, and HEOS Extend. HEOS by Denon products are widely available in the marketplace. D+M Group has assured Denon dealers, distributors, and customers that they will continue to be fully supported as Denon continues to innovate, invest, and provide new products, features, and functionality to its HEOS product line.

“We fully intend to take all necessary actions to protect our technology and product investment in our HEOS products," added Caudill.
