In the latest phase of the CE industry's seemingly endless series of patent disputes, Sonos is suing D&M Holdings, over the Denon Heos product line.
"For anyone who has looked at Denon’s Heos product line, you will recognize many of the same elements found in Sonos products, with little or no effort to differentiate features or functionality. Beginning with its product name and messaging (which in some instances they have just copied word for word), Denon borrows liberally from virtually all aspects of the Sonos story," Craig Shelburne, the Sonos cofounder who also serves as general counsel, said in a post on Sonos' official blog.
"We evaluated whether D&M Holdings violates other intellectual property rights of Sonos and have learned that D&M Holdings’ manufacture, distribution, and/or sale of the HEOS system infringe a number of Sonos patents related to wireless audio products. Because of these violations, we filed a lawsuit in Delaware, our state of incorporation. -"
