Audio giant, Sonos has filed a lawsuit in a Californian court against Lenbrook Industries, the parent company of Bluesound, accusing the company of patent infringement.

The plaintiff claims that Lenbrook has infringed on seven of its patents with the Bluesound brand.

According to the lawsuit, Sonos reportedly sent Lenbrook a notice of infringement on 70 patents in November 2018. Another notice on 45 other patents was reportedly sent in June of 2019.

The lawsuit alleges that Lenbrook’s use to be a distributor of Sonos before establishing the Bluesound brand.

The plaintiff reportedly claims that the “defendants have had intimate knowledge of Sonos’ wireless audio products and technology since at least 2007, more than six years before defendants released their first Bluesound products. Instead of innovating to compete fairly with Sonos, defendants have merely copied Sonos.”

In response to this claim, the defendant has reportedly published a statement stating that “it respects the valid intellectual property rights of others, and in fact has entered into many patent licenses over its 40-year history”.

The statement added that “Lenbrook’s high-resolution audio capabilities substantively differentiates Lenbrook’s products from those of Sonos and many other of Sonos’ actual direct competitors”.

“Lenbrook believes it is generally recognised by the industry as the first legacy audio company to deliver such a complete and differentiated solution to the audiophile marketplace”.

“As a respected premium player in the specialised consumer and commercial audio industry, Lenbrook takes its reputation for integrity, partnerships and goodwill seriously and looks forward to a prompt resolution of Sonos’ claims”, Lenbrook reportedly said.

The plaintiff claims that Lenbrook infringement on its patents has caused lots of damages, confusion and unfair competition.
