Mueller reports, “Walter Isaacson’s Steve Jobs biography comes into play. That biography has been quoted a lot in patent litigation, but usually only the ‘thermonuclear war’ part. Here’s the related passage from Google’s brief: “Here, the technology of the ’862 patent was recognized as a ‘breakthrough’ by none other than Apple’s former CEO (Mr. Steve Jobs). On cross examination, Apple’s expert, Mr. Lanning, could not deny that Mr. Jobs himself characterized the incorporation of a proximity sensor into the iPhone as a ‘breakthrough’ to his biographer, Walter Isaacson: ‘[a]nother breakthrough was the sensor that figured out when you put the phone to your ear, so that your lobes didn’t accidentally activate some function.’ [...] The sensor described by Mr. Jobs is the very technology that the ALJ found to infringe. [...] And there can be no doubt that this passage refers to the technology of the ’862 patent: it describes a sensor that prevents the inadvertent actuation of the phone when it is put to the user’s ear. The recognition that the invention of the ’862 patent was a ‘breakthrough’ weighs heavily against a finding of obviousness, particularly since it came from Apple itself.“
“Assuming the quote is correct, Steve Jobs was impressed by the sensor that figured out when you put the phone to your ear,” Mueller reports. “But Motorola’s ’862 patent is not a patent on a way to detect such proximity.”
