Because the goal of the EU is to create a common market. A EU-wide judiciary is consequently necessary to enforce certain laws (especially those that regulate the common market).
Yes, that's the goal. Doesn't really work so far for a lot of things, among which this kind of stuff. So do you know facts about this or was this a guess based on 'united europe' propaganda? Serious question; I am curious! I have never heard of anything like that and the Dutch press is saying that they don't have clue why a German judge ruling would govern the rest of EU and if it does, why not NL.
No guess, that's just how it is. Preliminary injunctions about community designs apply EU wide. Apple asked in their request for the injunction (German, http://www.scribd.com/doc/61993811/10-08-04-Apple-Motion-for...) to exclude the Netherlands from the injunction. Apple is suing Samsung separatly in the Netherlands.
The press you are reading seems to be exceedingly bad at its job.
