Apple and Motorola faced off in a court hearing in Düsseldorf, Germany earlier today, Dow Jones reports. Motorola is being sued by Apple over three different design concepts, as well as alleged violation of a competition law. Specifically Apple is upset over the Motorola Xoom, which it says imitates the first-generation iPad with only minor design differences. Motorola is exploiting Apple's reputation unfairly, Apple counsel told the court.
