If they want to do business in German* jurisdiction, they operate in Germany*. Doesn't matter where the HQ is, as Musk learned the hard way with the also-dramatic-but-less-so case in Brazil.

If they don't want to do business in Germany*, they don't get to file a patent in Germany*, they don't get to sue Germany* for ignoring a patent that was geographically limited to not include Germany*.

* might be "EU", I have not checked.
