According to the U.S. Copyright office ...
"Blank forms and similar works designed to record rather than to convey information cannot be protected by copyright.
"In order to be protected by copyright, a work must contain at least a certain minimum amount of original
literary, pictorial, or musical expression. Copyright does not extend to names, titles, and short phrases or clauses
such as column headings or simple checklists. The format, arrangement, or typography of a work is not protected.
Furthermore, copyright protection does not extend to works consisting entirely of information that is common
property containing no original authorship, for example: standard calendars, height and weight charts, tape measures and rulers, schedules of sporting events, and lists or tables taken from public documents or other common sources.
"Only the actual expression of the author can be protected by copyright. The ideas, plans, methods, or systems
described or embodied in a work are not protected by copyright. Thus, there is no way to secure copyright
protection for the idea or principle behind a blank form or similar work or for any of the methods or systems involved in it.
"An original literary or pictorial work is subject to copyright registration even though it is published in conjunction
with a blank form or other material not protected by copyright, provided that the requirements of the copyright
law have been met. However, copyright in such a case would extend protection only to the original literary or
pictorial expression used by the author, as distinguished from the blank form or other unprotected aspects of the
work.
"For example: copyright protection for original photographs or an original compilation of terms or phrases
published in conjunction with a blank form would extend only to the original photographs or compilation of terms or
phrases and not to the blank form."
