What I don't get, and I hope somebody can enlighten me here is this: Isn't Mojang a swedish company, registered in Sweden? How can the US patent law apply to Sweden since Sweden has a different patent law?
For example, I have my company in Germany, where it's (almost) impossible to get a patent for software patents. So if a greedy patent troll in Texas decides that one of my apps infringes their patents, can they even sue since my company is obviously in Germany? Or can they only stop me from selling in the US? (which would be a huge drawback, of course).
That's a very good question - and as all good questions it's difficult to answer: it depends. :)
There was recently a case where Håkan Lans argued he should not have to pay Acer after having lost a patent suit in Washington, because he is a Swedish citizen and the american verdict was according to him unjust. He first lost, but appealed and won in the appellate court (Hovrätten) [1]. The court argued that since there was no contract between the parties governing jurisdiction the foreign court decision could not be used in a Swedish court as proof of debt. Therefore Acer would have to sue Håkan Lans in Sweden, and have a Swedish court rule on the merits of the case, if they wanted the aid of Swedish authorities in collecting damages.

How is such a situation handled?
