The CEO of Canada's Brick Brewing Company has told just-drinks his business will "aggressively defend" an intellectual property lawsuit brought by Anheuser-Busch InBev.

A-B InBev has filed a claim at the Canada Federal Court claiming Brick infringed its Bud Light Lime trademark by selling its Red Baron Lime beer brand in Ontario, depreciating its goodwill, with consumers confusing the two brands.

Brick CEO George Croft told just-drinks late last week: "We believe this case is completely without merit. We strongly believe Canadian consumers are better served with more choice and competition."

Croft said that in 365 of the 438 Ontario Beer Store outlets stocking Red Baron Lime, consumers cannot see the beer bottles, which both use clear glass and green labelling. Instead, shoppers order six-packs from cashiers after browsing beer label wall panels.

A-B InBev did not return just-drinks' calls.
