Apple was ordered by a federal jury in the Southern District of California to pay San Diego-based Taction Technology more than $5.7 billion for infringing two patents covering haptic feedback in iPhones and Apple Watches. The Sept. 26 award is the largest patent-infringement verdict in U.S. history. The patents concern Taction’s technology and Apple’s Taptic Engine, which produces tapping vibrations. Apple rejected the finding and said it would appeal. Taction filed the lawsuit in 2021, while Apple argued that its products did not use Taction’s technology and that the patents were invalid. The U.S. Court of Appeals for the Federal Circuit revived the case last year after a San Diego federal judge ruled in 2023 that Apple had not infringed the patents.
