New England Patriots – '19-0' and '19-0 The Perfect Season'
In an embarrassing move on their part, the New England Patriots applied to trademark the phrases “19-0” and “19-0 The Perfect Season” in 2008, as the team was heading into the Super Bowl XLII with an 18-0 record. The move, of course, was meant to provide the franchise with greater merchandising rights were they to win the big game. Unfortunately for New England, the team lost. The loss brought much enjoyment to the New York Post, which in a whimsical move filed a trademark application for 18-1.
