Smartphone maker HTC is taking rival Apple to court in the UK just weeks after losing a preliminary ruling over two patent violations in the US.
The latest case was filed at the High Court on 29 July according to reports on Bloomberg, but the exact nature of the litigation in HTC Europe Co v Apple Inc was not specified.
Simmering relations between the bitter rivals bubbled over in recent times, kickstarted in March by Apple's lawsuit against HTC citing 20 patent violations and followed up by a second case only last month.
Taiwanese vendor HTC has also weighed in with its own patent fight against Apple, claiming it too is trying to defend its intellectual property.
First blood was drawn by Apple recently after the US International Trade Commission upheld the complaint against HTC, in a preliminary ruling, which when concluded could result in its product being banned from the US by year-end.
Apple and HTC were unavailable for comment at the time of going to press. ®
