The device, which went on sale in stores Friday, racked up 2 million pre-orders, making it the best-selling iPhone yet and the biggest rival to Samsung's Galaxy S III. (See iPhone 5: A 4G Stress Test and Samsung's Big Bang: 5 US Carriers Get the S III.)
Samsung wrote in a U.S. court filing that it expects "to add the iPhone 5 as an accused product" soon, anticipating it will infringe on the same "Samsung patents-in-suit in the same way as the other accused iPhone models."
Samsung's lawsuit comes less than a month after it lost to Apple in U.S. court to the tune of US$1.05 billion in damages. The jury found that Apple did not infringe on any Samsung patents, a verdict the South Korean company continues to fight.
