AB InBev has failed in its latest attempt to take sole possession of the Budweiser name in the UK.

The Court of Appeal this morning ruled that Czech brewer Budejovicky Budvar was entitled to continue using the Budweiser name on its beer.

Its ruling marks the latest chapter in a long-running battle that last September saw the European Union’s highest court also rule in favour of the Czech brewer.

Both companies were given permission by the Court of Appeal to simultaneously register the Budweiser trade mark in 2000. But in 2005 Anheuser-Busch – now part of AB InBev – began legal action to take sole possession.

“As a result of the decades-long honest use of the Budweiser mark by both Budvar and Anheuser-Busch in the UK, both parties should be entitled to a trade mark registration,” said Mark Blair of law firm Marks & Clerk, which acted for Budvar.

“Today’s judgment allows the trade mark register to reflect the reality of the situation in the market place – that both brands co-exist and have done so for many years.”
