More bad news for struggling BlackBerry maker Research in Motion.
The Canadian company has lost a contract dispute over the use of Nokia patents, which could threaten the sale of BlackBerrys.
Nokia has asked courts in the U.S., Canada and Britain to block sales of BlackBerry smartphones until the two companies agree on royalty rates, according to Reuters. A halt in product sales would be averted if the sides can reach an agreement first.
Finnish company Nokia signed a cross-licensing agreement with RIM that covered standards-essential cellular patents in 2003 and later amended that arrangement in 2008, Reuters said.
