Immersion has filed multiple lawsuits against Apple and AT&T, claiming the two violate its haptic feedback patents. Specifically, Immersion believes the Apple iPhone 6/6 Plus, iPhone 6s/6s Plus, Apple Watch, Watch Sport, and Watch Edition make use to two patents pertaining to "haptic feedback system with stored effects" and "method and apparatus for providing tactile sensations." The iPhone 6s and 6s Plus are further accused of infringing a third patent for "interactivity model for shared feedback on mobile devices" -- or 3D Touch, the defining feature of the two phones. Immersion didn't immediately make clear AT&T's role in the complaint. The company filed lawsuits with the U.S. International Trade Commission seeking a ban on the devices, as well as a lawsuit with the U.S. District Court for the District of Delaware seeking monetary damages. Immersion develops and makes touch-based feedback systems for mobile devices.
