Apple has sued Samsung for a presumably ridiculous amount, claiming that the Korean manufacturer has ripped off the “look and feel” of its devices. The filing mentions several phones, including the Samsung Galaxy S, as well as the Samsung Galaxy Tab.
Jobs and co say: "Rather than innovate and develop its own technology and a unique Samsung style for its smart phone products and computer tablets, Samsung chose to copy Apple's technology, user interface and innovative style in these infringing products.”
Of course that “user interface” is Android, with Samsung’s TouchWiz UI on top. TouchWiz doesn’t add a great deal - it's essentially still Android, though we doubt we’ll see Apple filing similar suits against every manufacturer of Android handsets. You never know, though.
Ironically, Apple is thought to be Samsung’s second-biggest client, right behind Sony. Apple is said to have spent as much as $5.7 billion buying components from the Koreans in 2010.
Samsung has said that it has “no choice but [to] respond strongly,” and is reportedly considering a counter-suit suggesting that Apple has infringed on a number of its wireless patents.
Apple is also battling Microsoft over use of the term “App Store”, which it believes it has exclusive rights to.
