Immersion expands patent lawsuit against Apple over haptic feedback technology
Earlier this year Immersion Corporation, one of the leading companies in haptic feedback technology, filed a lawsuit against Apple over haptic technology used in the iPhone 6, iPhone 6s, and Apple Watch. Today, the company has filed a second lawsuit against Apple and AT&T in which it says the MacBook and MacBook Pro violate one patent relating to haptic feedback. Additionally, Immersion says the iPhone 6s infringes on three more of its patents not mentioned in the first lawsuit.
