Samsung Electronics Co Ltd (005930.KS) asked a U.S. appeals court on Thursday to toss out an order that it pay Apple Inc. (AAPL.O) $930 million for infringing on iPhone patents to make its Galaxy line of smartphones and tablets. The hearing at the U.S. Court of Appeals for the Federal Circuit was the latest fight between the two smartphone makers, which have been litigating around the world for three years, each accusing the other of infringing patents in making smartphones and other mobile devices. They have essentially fought to a draw in about a dozen countries, but in August announced that they had agreed to withdraw all patent lawsuits against each other except in the United States.

In this case, Samsung asked the court to throw out a decision from the U.S. District Court for the Northern District of California which had found that Samsung infringed Apple patents and ordered it to pay the iPhone and iPad maker $930 million, a reduction from an earlier award of $1 billion. Kathleen Sullivan, a lawyer with Quinn Emanuel Urquhart & Sullivan LLP who represents Samsung, argued that the lower court erred in deciding that the design and trade dress patents were infringed because the Samsung phones did not carry an Apple logo, did not have a "home" button like an iPhone and had speaker slots in different places than the Apple phones. "Apple was awarded Samsung's total profits on those (Samsung) phones, which was absurd," she said, arguing that it was akin to awarding entire profits on a car because of an infringing cup holder.
