Shortly after the announcement of the iPhone X in September, my colleague Natasha Lomas noted the similarities between the phone and how WebOS operated on the Palm Pre. She ended her article, noting “in the iPhone X it’s clear you’re looking at a little ghost of the Pre.”

It seems that Qualcomm’s legal team was taking note; they cited that line in a complaint alleging that Apple ripped off Palm’s patented interface.
