Samsung Electronics was unbowed over the weekend after devastating rulings in Korean and a landmark U.S. patent case against Apple and vowed to appeal the ruling and file additional lawsuits against the U.S. company.

Jurors in the U.S. district court awarded Apple US$1.05 billion in damages for copying Apple's designs but struck down every single counter-claim by Samsung.

Apple, meanwhile, has sought a court order to ban Samsung smartphones and touch-screen tablets in the U.S. following the jury decision. The Northern District Court of California has asked Apple to submit by Monday a detailed list of the products involved.

A final ruling by Judge Lucy Koh is expected on Sept. 20, but the legal battle between the two electronics giants is expected to intensify.

"We did not expect this fight to end quickly," said a Samsung executive. "We will appeal if the final ruling coincides with the jury decision, and the ultimate winner will be determined based on additional lawsuits focusing on LTE technology."
