Faced with an ongoing patent battle in the US that threatens to place injunctions on its products, RIM is focusing heavily on Europe and has launched a tri-band full color BlackBerry PDA this week – only to find itself attacked by another intellectual property lawsuit, this time from a Luxembourg-based company.

RIM and T-Mobile USA have been sued in Delaware by InPro II Licensing, a Luxembourg-based licensing firm, which claims that the companies are infringing its patents and is calling for damages "in no event less than a reasonable royalty". RIM - which is appealing against an injunction granted to US intellectual property company NTP that could potentially ban it from selling its products – has filed a suit in federal court in Dallas asking for a ruling that the InPro patents are invalid.
