London (UK) - Research in Motion, Ltd. won a "nullity action" in the British High Court of Justice, Chancery Division, effectively invalidating a patent asserted by Luxembourg-based holding company InPro, which may have overlapped similar assertions by the BlackBerry manufacturer. According to RIM, all of InPro’s patent claims against RIM in the UK have now been declared invalid, effectively taking RIM off the hook in at least one more country.

The nullification of the British patent follows a similar action taken last Friday against InPro, by a German patent court in Munich. InPro is not related to NTP, Inc., the American holding company making similar assertions in the US.
