San Francisco - The patent-infringement suits just keep on coming in the cellphone market.

This time, Dolby Laboratories sued Research In Motion in the U.S. and Germany, seeking financial damages and an injunction on the sale of BlackBerry smartphones and the Playbook tablet.

Dolby contends the devices infringe on Dolby patents involving digital audio compression technologies that have been licensed by all other major cellphone makers. The patents deliver high-quality audio using "extremely limited amounts of transmission and/or storage space," Dolby said.

The patented technologies have been incorporated into the international standard called High Efficiency Advanced Audio Coding (HE AAC), which compressed digital audio to less than 10 percent of its original digital file size, Dolby said.

Lawsuits were filed in the U.S. District Court for the Northern District of California and, in Germany, in the District Court of Mannheim.

 Just yesterday, Nokia and Apple settled their patent disputes, but Apple's disputes with Motorola, Samsung and HTC are still outstanding.
