Red Baron Lime v. Bud Light Lime
As reported on in a story on the Canadian Trademark Blog, the dispute between Brick Brewing and Budweiser hinges on the websites:
Brick’s: http://www.lustforlime.com/
Budweiser’s: http://www.budlightlime.com/
As noted in the story, both sites feature prominent use of the colour green and images of young people in swimsuits.
