In October 2016, the U.S. Court of Appeals for the Federal Circuit reinstated Apple's award after a lower court found Samsung to have infringed upon several popular iPhone features, including slide-to-unlock and autocorrect.
The lawsuit, from 2011, is so old that slide-to-unlock isn't even used on iPhones anymore. Unlocking an iPhone on iOS 10 or later requires using Face ID on iPhone X, and Touch ID or pressing the Home button on older iPhone models.
This case is not to be confused with another 2011 lawsuit in which Apple accused Samsung of copying the iPhone's design with its Galaxy-branded smartphones. A damages retrial in that lawsuit is scheduled for next May.
