NOT a MS fanboy, far from it, but Microsoft is in the right here. Microsoft and Motorola have been in court in the US over patent and FRAND for almost a year before Motorola decided to try to get an injunction in Germany since Germany is very patent-holder friendly and not FRAND-friendly. Essentially, Motorola tried to short-circuit the US lawsuit before it could be fully adjudicated and it would seem they didn't like their chances of winning in the US.
It would be like arguing with your neighbor over the shrubs and your neighbor then going to another country to sue you over it. What's the point of that?
