Apple must show patents valid in Samsung case: judge| Reuters

(Reuters) - A U.S. judge said that Samsung Electronic's Galaxy tablets infringe Apple Inc's iPad patents, but added that Apple has a problem establishing the validity of its patents in the latest courtroom face-off between the technology giants. U.S. District Judge Lucy Koh made the comments in a court hearing on Thursday, but has yet to rule on Apple's request to bar some Galaxy products from being sold in the United States.
