A federal jury determined that iPhones and Apple Watches utilized patented vibration mechanisms without authorization in a court ruling delivered Sept. 26. Apple must pay $5.7 billion in damages, making the award the largest ever issued in a legal dispute concerning haptic technology.

The verdict involves the tactile feedback systems that provide sensory alerts and user interaction on the company's most popular handsets and wearables. The ruling finds that these flagship devices infringed on patents covering the haptic technology used to drive their internal vibration engines.
