(Reuters) - BlackBerry Ltd (BB.TO) (BBRY.O) on Friday won the dismissal of a U.S. lawsuit accusing it of fraudulently inflating its stock price by painting a misleadingly upbeat picture of the prospects for its BlackBerry 10 smartphone line.

U.S. District Judge Thomas Griesa in Manhattan said the plaintiffs failed to plausibly allege that BlackBerry and top officials made material misrepresentations or omissions, or intended to defraud them.
