EP 1148681 is a EU patent owned by Nokia. Nokia has been granted an injunction against all of HTC's Android devices based on this patent.
This shouldn't even be patentable in the EU, since software patents aren't allowed here, and this patent builds entirely on known hardware, leaving it to a software component to give the patent leverage.
How can this patent be shown as void in the EU? Can we present prior art? Can we show that the patent is a "pure" software patent, by showing that the hardware base for it is prior art? Is there a similar US-patent?
