Football season is here and the Twitterverse has already been flooded with fans posting about their favorite teams and players, but some fans are outraged by the Chicago Bears using #GoBears.

Why? Well because the Chicago Bears don’t actually own the rights to the trademark. In fact, the Bears also don’t own the trademark to their other marquee saying “Bear Down.”

The University of California-Berkeley actually owns the rights to “Go Bears” and the University of Arizona holds the trademark for “Bear Down.”

The California Golden Bears actually called out the Chicago Bears on Twitter for adding an orange “C” to the end of the hashtag “Go Bears.”

The official Twitter account of the Golden Bears actually called the Chicago Bears out.

Let’s hope Da Bears have better luck this season on the football field then they did on Twitter.
