Dolby Sues RIM For Audio Patents

Dolby Labs is suing Research in Motion claiming the BlackBerry and PlayBook infringe on Dolby’s patents in HE AAC audio compression technology and Dolby claims this intellectual property is protected under patents that several other smartphone makers have already licensed. Although HE AAC is an ISO standard for audio compression, t’s a lossy compression format used in a wide variety of media players, smartphones and other consumer electronics and the etup requires hardware and software makers that support HE AAC to execute a license, but content owners are not required to do so…………..


Dolby Laboratories through its wholly-owned subsidiary Dolby International has filed patent infringement lawsuits in the U.S. and Germany against Research In Motion, a Canadian manufacturer of wireless handset and tablet devices. The lawsuits seek recovery of financial damages and injunctions to halt sales of the many RIM products that infringe Dolby‘s patents. The lawsuits explain that RIM infringes Dolby patents covering highly efficient digital audio compression technologies which allow manufacturers and consumers to provide and enjoy high quality audio while using extremely limited amounts of transmission and/or storage space for such audio. RIM employs Dolby’s patented technologies in its Blackberry smart phones and Playbook tablet devices, without having obtained licenses from Dolby, the lawsuits say. All other major smart phone makers have agreed to license the Dolby technologies which are the subject of this litigation. Dolby‘s patented technologies, which have been incorporated into the international standard known as High Efficiency Advanced Audio Coding (HE AAC), provide the core of HE AAC. Demonstrating the value of the Dolby technologies, HE AAC is widely used in consumer electronics devices such as smart phones, portable music players, and computer tablets to play back music and other digitized audio that has been compressed to less than 10% of its original digital file size. “Litigation was regrettably our last resort after RIM declined to pay for the use of Dolby’s technology,” said Andy Sherman, executive vice president and general counsel of Dolby. “We have a duty to protect our intellectual property.”
