What kinds of work are eligible for "work made for hire" status?
There are now only 9 categories of works eligible for "work made for hire" status. While these 9 categories are fairly broad and probably encompass most of what firms buy and sell, there may be significant gaps.
A "work made for hire" is one specially ordered or commissioned for use as:
(1) a contribution to a collective work
(2) part of a motion picture or other audiovisual work
