Bose files lawsuit against Apple's Beats over noise canceling tech

Bose Corporation filed the complaint against Beats Electronics, LLC and Beats Electronics International Limited in a Delaware court, asserting that Beats has infringed on Bose's "valuable patented technology for noise cancelling headphones." The lawsuit is joined by a complaint that has been filed with the International Trade Commission seeking an injunction.

Specifically, Bose accuses the Beats "Studio" and "Studio Wireless," which are advertised to feature "Adaptive Noise Cancellation," of infringing on its patents. Bose asserts to the court that "Beats knows or is willfully blind to the fact that" its products are infringing on its patents.

In the complaint, Bose states that the company pioneered the technology behind active noise reduction, which reduces unwanted noise by introducing a second sound source that interferes with it. Headphones featuring active noise reduction usually rely on a microphone to reduce background noise.

Bose has been selling its "QuietComfort" branded headphones with this technology since 2000. For the latest "QuietComfort 20" headphones, Bose says they are protected by U.S. Patent Nos. 6,717,537; 8,073,150; 8,073,151; 8,054,992; and 8,345,888. They are titled:

• '537: "Method and Apparatus for Minimizing Latency in Digital Signal Processing Systems"
• '150: "Dynamically Configurable ANR Signal Processing Topology"
• '151: "Dynamically Configurable ANR Filter Block Technology"
• '992: "High Frequency Compensating"
• '888: "Digital High Frequency Phase Compensation"

If the lawsuit drags out, it could last until Beats officially becomes a part of Apple, which would make the lawsuit targeting Apple's bottom line. Bose is seeking damages in the suit of an unspecified amount.

Apple announced in May that it will buy Beats Electronics, which makes premium headphones, as well as the Beats Audio on-demand music streaming service for a combined $3 billion. As part of the deal, company co-founders Jimmy Iovine and Dr. Dre will become employees of Apple.

Apple expects the deal to close in its fiscal fourth quarter, which concludes in September, pending regulatory approval. The full complaint from Bose is included below:
