$1 billion Samsung payout to Apple halved as the tech giants are ordered back into court in the ongoing battle for smartphone dominance Samsung and Apple will face off yet again after a federal judge ordered them to return to court and slashed more than $450 million from a judgement Samsung had been ordered to pay Apple. Last August a jury awarded Apple more than $1 billion in damages after finding that Samsung copied the design and software of the iPhone. 'Some of the awards rested on impermissible legal theories,' ruled U.S. District Judge Lucy Koh. Tech fight: Apple and Samsung's battle for dominance of the smartphone market has led the two companies to square off in court on several occasions Epic battle: Since the iPhone debuted Samsung has fought to catch up and set record sales numbers with the latest Galaxy A new 'trial on damages' will affect the formula and therefor the amount Samsung owes Apple, CNN reports. New court proceedings will focus on Samsung products as Koh questioned the amount of damages ordered because of their similarity to the iPhone. The products in question are the Galaxy Prevail, Gem, Indulge, Infuse 4G, Galaxy SII AT&T, Captivate, Continuum, Droid Charge, Epic 4G, Exhibit 4G, Galaxy Tab, Nexus S 4G, Replenish and Transform. After cutting the judgement, Samsung still has to pay just under $600 million. The courtroom showdown began when Apple accused Samsung of stealing its designs for the iPhone and iPad. They sued for $2.5 billion. Thrown out: Judge Lucy Haeran Koh slashed the $1 billion judgement awarded to Apple writing that judgement 'rested on impermissible legal theories' Samsung countersued for $519 million and for patent infringement. A nine-person jury found Samsung guilty of 'willful' violations of patents and asked that Apple be awarded more than $1 billion while giving nothing to Samsung for its counterclaims. 'This is a huge win for Apple,' Stanford law professor Mark Lemley said at the time. He called the award 'just large enough to make it the largest surviving patent verdict in history.' Samsung claimed the jury foreman, Velvin Hogan, was prejudiced becase he had been sued by Seagate, his former employer. Samsung is Seagate's largest investor. Judge Koh denied Samsung's request for a new trial based on the connection. Thieves: A South Korean judge previously ruled that each company had infringed on the other's designs The two companies are battling for dominance of the smartphone market. Samsung's latest Galaxy phone smashed sales records this January when it moved more than 100 million units. As the companies fight for market share, the competition has often led to the courtroom. A South Korean court ruled that each company had infringed on the other's patents and banned the sale of the iPhone 3GS, iPhone 4, two iPad models and Samsung's Galaxy S2.
