The round curves belong to Apple

Apple has been upheld in court in their case against Samsung in Germany. Rounded corners and flat screens are reserved for Apple.
Court of Germany has chosen to maintain the national ban on the sale of Samsung Galaxy Tab 10.1.

According to Judge Johanna Brueckner-Hoffmann's "Apple minimalist design is not the only technical solution to make a tablet computer, other designs are possible."

On top of that the judge mentions the iPads rounded corners, modern, minimalist design and flat screen in the decision.

The ban only applies to Germany, not for whole Europe, as Apple had hoped
