Dolby International, has filed patent infringement lawsuits in the U.S. and Germany against Research In Motion. The lawsuits seek recovery of financial damages and injunctions to halt sales of the many RIM products that infringe Dolby’s patents.
“Dolby’s patented technologies, which’ve 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.”
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.
