U.S. District Judge Lucy Koh said Samsung’s Galaxy tabets infringed on Apple’s patents, but left the onus on Apple to establish the validity of their patents. As for issuing an injunction against Samsung:

At the hearing on Thursday in a San Jose, California federal court, Koh also said she would deny Apple’s request for an injunction based on one of Apple’s so-called “utility” patents.

She did not say whether she would grant the injunction based on three other Apple “design” patents.

The following courtroom conversation helps illustrate why Apple is going after Samsung for allegedly copying its flagship iOS devices:

Koh frequently remarked on the similarity between each company’s tablets. At one point during the hearing, she held one black glass tablet in each hand above her head, and asked Sullivan if she could identify which company produced which.

“Not at this distance your honor,” said Sullivan, who stood at a podium roughly ten feet away.

“Can any of Samsung’s lawyers tell me which one is Samsung and which one is Apple?” Koh asked. A moment later, one of the lawyers supplied the right answer.
