Baltimore Ravens

1996–1998
The Ravens' original logo was the subject of a lawsuit filed by Frederick E. Bouchat, a local Maryland artist and security guard who had submitted a similar design that ultimately went unused.

1999–present
In 1999, the Ravens changed their primary logo to a purple raven with the gold letter "B" on its side. This came after the US Fourth Circuit Court of Appeals ruled that the previous logo infringed on the copyright of an unused design.
