Facebook has filed thousands of patent applications since it went public in 2012. One of them describes using forward-facing cameras to analyze your expressions and detect whether you’re bored or surprised by what you see on your feed. Another contemplates using your phone’s microphone to determine which TV show you’re watching. Others imagine systems to guess whether you’re getting married soon, predict your socioeconomic status and track how much you’re sleeping.
A review of hundreds of Facebook’s patent applications reveals that the company has considered tracking almost every aspect of its users’ lives: where you are, who you spend time with, whether you’re in a romantic relationship, which brands and politicians you’re talking about. The company has even attempted to patent a method for predicting when your friends will die.
Facebook has said repeatedly that its patent applications should not be taken as indications of future product plans. “Most of the technology outlined in these patents has not been included in any of our products, and never will be,” Allen Lo, a Facebook vice president and deputy general counsel, and the company’s head of intellectual property, said in an email.
