That's crazy, copyright also counts as intellectual property, so technically you'd have to promptly communicate to the company almost everything that you write (I'm pretty sure all of your HN posts would qualify), every stick figure you draw, every song you hum (you have copyright on your performance). That contract forbids you from doing any creative work for a year after you quit (or are fired). I don't suppose that contract included a year's wages as severence pay?
