The Cloudy World of Look-A-Like Products - Aldi Successfully Defends Allegations of Trade Mark Infringement


Recently the High Court of Justice of England and Wales handed down its judgment in a trade mark infringement proceeding between Aldi v Thatcher’s that had been being watched by many.

Thatchers had sued Aldi for trade mark infringement and passing off over claims that the supermarket’s Taurus lemonade brand was a copycat of its Cloudy Lemon Cider in both taste and appearance (see below).

The case had been closely followed by many brand owners who are becoming increasingly concerned by the potential damage to their brands by look-a-like products. However, as Aldi was ultimately successful in its defence in this case, the judgment reiterates the difficulties that brand owners face and the need for close scrutiny and strategic thinking when seeking to prevent a look-a-like product damaging a market leading brand.

The Decision

Ultimately, the Court ruled that there was no trade mark infringement nor passing off by Aldi. The Judge concluded that there was a “low degree of similarity” between the two products and although the Aldi packaging would “cause a link in the mind of the average consumer”, there was no likelihood of confusion. The Judge also found that the Aldi product did not take unfair advantage of the reputation of the cider company’s existing product and had been in no way “detrimental” to the reputation of the Thatcher’s existing trade mark.

Of particular note from the judgment were the following matters:

Thatchers have given no indication of plans to appeal the decision, however, as significant weight has been placed on Aldi’s lack of intention to infringe and there was a finding that Aldi’s new packaging did not “significantly depart[s] from its house style” as the logo and name remain, it will be interesting to see if Thatchers is emboldened to do so.
