The Seattle Kraken has just been served a lawsuit for allegedly breaking trademark law. The lawsuit alleges that the Kraken's Winter Classic jersey contains a nearly identical red 'S' as the Seattle Metropolitan jersey, owned by Paul Kim, who filed the lawsuit.
Winter Classic jerseys are commonly used to celebrate the history of the teams playing, however, a unique situation has arisen here since the Kraken don't have that long of a recent history.
While the attempt to honour the Metropolitans is nice, if the Kraken doesn't own the trademark, they are clearly violating some trademark issues. Normally, since a team's jersey and logo go along with ownership changes, this isn't an issue.
