You probably haven't heard of Immersion, but it's a company that does two things well: haptic technology and hiring lawyers. The company is already suing Apple, claiming that the iPhone 6/6S and Apple Watch's force touch violate several of its patents. Now, the company is doubling down, firing another legal broadside against the Mac-maker for the same thing, although weirdly, AT&T has been roped in too. According to 9to5 Mac, the reason that the phone company is included is because, wait for it, it sells Apple products. We're too polite to point out that Verizon, T-Mobile and Sprint exist, but we imagine it won't be long before they're added to the case.
