Google has lost its appeal in a trademark case brought by Louis Vuitton, which complained that advertisers were using its name unfairly to sell goods online.

In its ruling yesterday, the Paris Court of Appeals increased the damages it had previously awarded to Louis Vuitton to €300,000 (about £200,000), from €200,000 (£135,000), and boosted its legal expenses to €60,000 (£40,000) from €15,000 (£10,000), Louis Vuitton said.

The luxury goods maker had objected to Google accepting payments from third parties for displaying advertisements alongside search results for Louis Vuitton's trademarks. Google lost an initial ruling in the case in February last year.

The search company is barred from using any Louis Vuitton trademarks in connection to its advertising services on all of its websites accessible from France, Louis Vuitton said. It must also pay for the ruling to be published in four newspapers and on Le Journal Du Net.

A spokeswoman for Google in France did not immediately respond to a request for comment. Google has said it no longer permits companies to buy advertising keywords if they are the trademarks of other companies.

The Louis Vuitton case is one of several that Google has faced related to AdWords. Early last year its French subsidiary was ordered to pay €75,000 (£50,000) in fines and legal costs for selling advertisements alongside searches related to a French travel agent's trademarks.

The company has also been sued on similar grounds in the US, Germany, Israel, Italy and Austria, it said in a recent US regulatory filing. Yahoo's sponsored search results division, Overture, has also lost a suit in France for selling advertisements next to the search results for a third party's brands.
