A United States federal jury in San Diego has ordered Apple to pay more than $5.7bn in damages after finding that the technology giant infringed two haptics patents owned by Taction Technology.

Taction sued Apple in 2021 at the U.S. District Court for the Southern District of California, accusing the company of profiting from its innovation by selling devices that allegedly used its patented vibration technology.

The case was initially dismissed in 2023, but the Federal Circuit later revived the lawsuit.

Apple said it would appeal the verdict, telling Bloomberg Law that it “does not use Taction’s technology.”

The lawsuit centred on U.S. Patent Nos. 10,659,885 and 10,820,117, which cover vibration-based tactile transducer technology that allows users to feel a device respond to their input. Taction argued that Apple’s Taptic Engine, used in iPhones and Apple Watches, incorporates its patented inventions without a licence or authorisation.

The jury trial began on September 14, with the seven jurors deliberating for two days after the proceedings concluded.

They returned at 1:15 p.m. Pacific Time on Friday and delivered a verdict in favour of Taction.
