The abstract of the patent published by the U.S. Patent and Trademark Office states: "Deadbolt locking devices for preventing a deadbolt from being unlocked from the outside are provided.

Various configurations of door hardware can include the position of the deadbolt knob in relation to the door knob, the angular position of the handle of the deadbolt when it is in the locked position, whether the door is hinged on the left or right side and whether the deadbolt knob turns clockwise or counter-clockwise to lock the door."
