That's what I originally thought, mainly because there's a kid in a YA book I actually am fond of who is nicknamed Patch. It's short for "Patrick", but he also has it because he has a fake eye that he hides behind an eyepatch. (He also hides various lockpicking devices inside of the eye, which he uses for his...erm job ^^)

But no, no one ever indicates that Patch has a real name. You'd think at least that would come up when Vee looked up his name.
