Thomas Ross, a businessman from Miramar, Florida, believes that Apple's iPhone, iPad and iPod stole the "essence" of his Electronic Reading Device, which he conceived in 1992. He's suing the tech giant for $10 billion in damages, and feels confident about his chances.
Ross's concept, which never went further than the design stage, would allow a user to read news articles and view images and videos on a flat touchscreen surface, the Guardian reports.
Ross's lawyer ordered in 2015 that Apple CEO Tim Cook immediately stop selling the devices, a request that was, perhaps unsurprisingly, not heeded.
Apple did not immediately respond to a request for comment.
