Apple has emerged the victor in a case of claimed patent infringement brought by Samsung to the US branch of the International Trade Commission (ITC), where a judge has ruled [PDF] that Apple was not infringing on any of four patents brought by Samsung. The Korean smartphone rival has tried repeatedly to prove that Apple is itself infringing on Samsung patents, but apart from a partial victory in its home country, has thus far been unable to persuade any courts of this notion. Apple had no comment on the victory.
