I think the Volagi guys are in the bit of trouble from what I can deduce. The simple fact that they keep saying they don't even know what they are being sued for is not a good sign, nor is it a good way to spend hundreds of thousands of dollars.
I am not drawing any conclusion yet and will be watching this closely. I really hope the Volagi guys, or more importantly the lawyers they hired, are good and lucky enough to get a sympathetic jury that has some common sense. This speaks a lot about our general litigious environment where any IP is involved.
