Dolby Sues Blackberry-Maker For Patent Infringement

Wed, 06/15/2011 - 8:39am

SAN FRANCISCO (AP) — Dolby International, a unit of audio equipment maker Dolby Laboratories Inc., is suing Research In Motion Ltd. for patent infringement in the U.S. and Germany.

Dolby alleges that RIM's Blackberry smartphones and Playbook tablet devices use its patented digital audio compression technology, which enables the playback of high-quality audio files using limited amounts of storage space, without a license.

Dolby, based in San Francisco, filed its lawsuits in the U.S. District Court for the Northern District of California and in the District Court of Mannheim in Mannheim, Germany.

The company is seeking financial damages and an injunction to halt the sale of RIM's products.

Canada's Research In Motion, based in Waterloo, Ontario, had no comment.
