  • Is comparative advertising unfair?

    THE EUROPEAN COURT OF JUSTICE (ECJ) IS IN THE midst of considering questions referred to it by the UK courts in three separate cases that should clarify the law regarding comparative advertising. This type of advertising, particularly when it identifies a competitor or a competitor’s goods or services by referring to a registered trade mark, is of particular concern to trade mark owners as their competitors normally seek to make unfavourable comparisons with their own goods or services, or to take advantage of being associated with the market leader’s brand.
