MISSOULA, Mont. -

A Montana brewery is suing one of the biggest names in beer over what it claims is a trademark violation.

Missoula's Big Sky Brewing says Anheuser-Busch copies it's "Hold my beer and watch this" campaign.

In federal court documents Big Sky Brewing says Anheuser-Busch released three Youtube videos on December 1, 2013 with actor John Krasinski centered around the phrase "hold my beer and watch this".

Big Sky says it has used the phrase since 2004 and held the trademark since September 8, 2009. The phrase is featured on cans of Big Sky beers.

The company is seeking an undisclosed amount in damages.
