Posted by Clinton Hesler on 26th July 2014

Bose is suing Beats over patents related to their noise-cancelling headphones. The lawsuit is expected to impact Apple as well, which officially purchased Beats for $3 billion in May.

The lawsuit, which was filed in the U.S. District Court for the District of Delaware, cites the following patents in question:

  • 8,073,151: “Dynamically configurable ANR filter block topology” by Joho et. al.. Includes 30 claims (2 indep.). Was application 12/430,994. Granted 12/6/2011.
  • 8,073,150: “Dynamically configurable ANR signal processing topology” by Joho et. al.. Includes 24 claims (2 indep.). Was application 12/430,990. Granted 12/6/2011.
  • 6,717,537: “Method and apparatus for minimizing latency in digital signal processing systems” by Fang et. al. Prosecuted by Thelen Reid & Priest LLP Robbins; Steven J.. Includes 19 claims (3 indep.). Was application 10/179,930. Granted 4/6/2004.
  • 8,345,888: “Digital high frequency phase compensation” by Carreras et. al.. Includes 16 claims (3 indep.). Was application 12/750,309. Granted 1/1/2013.
  • 8,054,992: “High frequency compensating” by Sapiejewski.. Includes 23 claims (6 indep.). Was application 11/409,894. Granted 11/8/2011.

Bose is claiming that Beats has infringed on some 50 years’ worth of research of noise-cancelling technology and a large amount of patents. That includes the Beats Studio Line, which includes the new Studio Wireless Bluetooth headphones, Bose claims.

“For almost 50 years, Bose has made significant investment in the research, development, engineering, and design of proprietary technologies now implemented in its products, such as noise cancelling headphones. Bose’s current line of noise cancelling headphones, for example, embodies inventions protected by at least 36 U.S. patents and applications (22 patents and 14 pending applications),” Bose wrote in its lawsuit.

The company is seeking an injunction against continued infringement, a full account of sales of infringing devices, damages which would include court costs, determination that the infringement is willful and upwards adjustment of damages accordingly, and “other relief,” which would be determined by the court.

Both Apple and Beats have yet to comment on the lawsuit. Apple is already in court battles with Samsung and other companies, and is now expected to face Bose in the courtroom since it recently acquired Beats.
