Samsung's Christmas gift to Apple won't be the $548 million it agreed to pay in its first patent squabble. It will be giving, instead, another serving of legal headache, though indirectly this time. As expected, Samsung has escalated its patent issues to the US' highest court. Although it is technically putting into question what is now commonly regarded to be an outdated patent system, in the end it will also affect the outcome of its two biggest patent fights with Apple. Especially the payment it has to make.
