Blackberry maker Research In Motion (RIM) is back in the UK patent courts going on the attack against a US adversary, at the same time as the company looks to replace its departing UK head of legal.
RIM is retaliating against Visto Corporation, which is suing RIM in Texas for patent infringement by trying to strike out a patent – the European parallel of one of the patents involved the US case – in the UK.
The action comes as the company searches for a new head of legal for its UK operations after department head Adam Feare left to join internet telephony company SpinVox.
RIM has employed a similar tactic before. Against Luxembourg IP company Inpro, RIM managed to fight off an infringement suit in Germany by invalidating the opposing patent in the UK High Court in February.
Tom Sanchez, chief patent counsel at RIM, has spoken out in the past against the use of juries in US patent trials and is an admirer of the High Court’s patent judges.
