A Baltimore artist named Frederick Bouchat designed what the Baltimore Ravens adopted as their first logo, but the team used the design from 1996 to 1998 without compensating or crediting Bouchat. Bouchat successfully sued the team for copyright infringement for using his logo, and the Ravens switched to their current logo after the 1998 season. What is the "fair use doctrine" and what interests are the "fair use doctrine" intended to protect? How does the "fair use doctrine" apply to the Bouchat case
