SAN FRANCISCO (AP) - A federal judge on Friday slashed nearly half of the $1 billion damage award a jury ordered Samsung Electronics to pay Apple Inc. after a high-profile trial over the rights to the design and technology running some of the world's most popular smartphones and tablet computers. U.S. District Court Judge Lucy Koh lowered the damages awarded to Apple Inc. by $450.5 million for 14 Samsung products including some products in its hot-selling Galaxy lineup, saying jurors had not properly followed her instruction in calculating some of the damages. She also concluded that mistakes had been made in determining when Apple had first notified Samsung about the alleged violations of patents for its trend-setting iPhone and IPad. Koh ordered a new trial to recalculate damages for those products. "We are pleased that the court decided to strike $450,514,650 from the jury's award," Samsung spokeswoman Lauren Restuccia said. Samsung intends to seek further review as to the remaining award. The judge said the tab will probably increase after the appeals of both companies are resolved. Apple is seeking more damages and Samsung a complete dismissal of the case in the U.S. Court of Appeals for the Federal Circuit, the Washington, D.C.-based court that handles all patent appeals. The new trial to recalculate the damages could also increase the award. Still, the ruling was the second significant setback in Koh's courtroom since the headline grabbing verdict was announced. In December, Koh refused to order a sales ban on the products the jury found infringed Apple's patents. She said Apple failed to prove the purloined technology is what drove consumers to buy a Samsung product instead of an Apple iPhone or iPad. Samsung says that it is continues to sell only three of the two dozen products found to have infringed Apple's patents. After a three-week trial closely followed in Silicon Valley, the jury decided that Samsung ripped off the trailblazing technology and sleek designs used by Apple to create its revolutionary iPhone and iPad. Jurors ordered Samsung to pay Apple $1.05 billion. Apple filed another lawsuit last year accusing Samsung's newer line of products of continuing to use technology controlled by Apple. Koh has scheduled trial in that case for early next year. She has implored both companies on several occasions to settle their difference with little success. Samsung has emerged as one of Apple's biggest rivals and has overtaken it as the leading smartphone maker.
