Koons won this case as the court argued that Koons' use of Blanch's work did not breach the fair use doctrine.  It is necessary to look at this later case in order to understand the court ruling of the earlier case: Rogers v. Koons.  By comparing the two cases we get a clearer idea of what fair use is and the complexities which are involved.  Moreover, the later case marks a more developed understanding, and that there is indeed change and progress within art law.
