This is a working collection of rules for slash signatures used in documents electronically filed before various government bodies.
Slash signature rules are greatly inconsistent. Most bodies follow a convention of “/s/ [name]” but there are exceptions, notably the Ninth Circuit and the U.S. Patent and Trademark Office. Some require the name to be the person’s actual name; others permit freeform text. Many bodies impose no specific requirement but recommend the ordinary convention; still others impose no requirement at all.
