RIM reported net income rose to $90.4 million, or 46 cents per share, in the third quarter ended Nov. 27, from $16.3 million, or 10 cents a share, a year earlier.
Excluding a litigation provision of $24.6 million, or 12 cents a share, it said its adjusted net income was $114.9 million, or 58 cents a share. The provision stems from its legal battle with U.S.-based patent-holding company NTP.

Overhanging RIM's prospects is the outcome of its legal battle with NTP, which successfully sued RIM in 2002 for patent infringement.
A U.S. appeals court upheld much of the patent infringement finding against RIM earlier this month, but said part of the earlier court ruling was flawed and sent the case back to a lower court.
RIM's stock fell after the ruling as a chorus of analysts said the decision was a major legal blow that strengthened NTP's negotiating position. They said the ruling increased the likelihood that RIM would settle the case out of court.
