San Francisco — Dolby Digital has filed patent infringement lawsuits in the United States and Germany against Blackberry maker Research In Motion (RIM).
The multi-million dollar company claims that many RIM products have infringed on its patents, which cover digital audio compression technologies that allow manufacturers and consumers to provide audio while using limited amounts of transmission and/or storage space for such audio.
“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 for Dolby. “We have a duty to protect our intellectual property.”
The lawsuit was filed in the U.S. District Court for the Northern District of California, and at the District Court of Mannheim in Germany.
