This week the US Patent & Trademark Office published a series of patent applications from Apple revealing how Siri works with various forms of smart lists. Siri is the name of Apple's intelligent personal assistant service that they introduced with their iPhone 4S in November 2011. Siri helps a user get things done just by asking. It allows the user to use their voice to send messages, schedule meetings, place phone calls, and more. Apple's four Siri related patents specifically cover performing actions, generating task items, organizing tasks and triggering notifications. Noteworthy is the fact that Apple once again clarifies that this voice-centric service that we know of as Siri will eventually be coming to the Mac. This is something that Apple had previously set in stone in a patent filing that we covered in a report back in September titled "Apple Patents Point to Siri Controlling iTunes on an iMac & more."
