Research in Motion Ltd. has been sued by the Dutch company NXP BV for allegedly infringing six patents by selling products such as the BlackBerry Torch, Curve and Bold, and the PlayBook tablet.
The patents were issued between 1997 and 2008, and relate to such matters as phone design and transmission of data.
NXP seeks a halt to the alleged infringements, compensatory and triple damages and other remedies.
A spokeswoman for Research in Motion was not immediately available for comment. In busy U.S. trading near midday, Research in Motion was down 6.3 per cent to $13.47.
NXP filed its lawsuit on Monday in the U.S. district court in Orlando, Florida. Research in Motion plans to hold its annual BlackBerry World conference there in early May.
The case is NXP BV v. Research in Motion Ltd et al., U.S. District Court, Middle District of Florida, No. 12-00498.
