Parodies are accorded a special status in copyright cases. Since a parody can't really succeed unless it borrows substantially from the parodied work, the normal rule that substantial borrowing amounts to infringement doesn't fit in this area. In judging whether a parody infringes on the parodied work, Courts will look at four factors: (1) purpose and character of the use, including whether the use is commercially motivated or instead is for nonprofit educational purposes; (2) nature of the copyrighted work; (3) amount and substantiality of the portion used in the newly created work in relation to the copyrighted work; and (4) effect of the use upon the potential market for or value of the copyrighted work (check out this link
for a more thorough discussion). Without knowing more about your parody or the manner in which you intend to use it, dupre
