The Dutch Supreme Court has ruled that the Samsung Galaxy Tab 10.1 doesn't infringe on the design of the Apple iPad, according to reports. Although Apple does hold a European design patent, the Court has limited the applicability of the patent based on prior art. The iPad has predecessors, such as a Knight Ridder concept tablet dating back well over a decade before Apple's product was released. The iPad may have a "unique character," the court adds, but the Galaxy Tab is sufficiently different that an informed person can tell.
