Unregistered Trademark Protection - the Tort of Passing Off and Brand Protection

Intellectual Property / Passing Off / Protection / Trade Mark Law

One of the ways in which a holder of an unregistered trademark right can be protected is under the law of passing off. There are three main criteria which needs to be established before one of the remedies available under passing off is given.


Shortcomings on registration of trademarks leaves businesses exposed, than what otherwise might be the case to protect brands from others taking advantage of the goodwill they have built up. This is not to say that businesses with unregistered trademarks do not have brand protection options. They do.

Trademark infringement is not the only option. A different form of action can be brought to protect unregistered trademarks of business brands.  The tort of passing off is a centuries old cause of action which protects businesses’ goodwill and reputation. It has a far broader and flexible application than a claim for registered trademark infringement. As such, what might not constitute infringement of a registered trademark, may well amount to passing off, and give the business the brand protection it is looking for.

Unregistered Trademark Rights and Brand Protection

Passing off is exclusively a common law remedy in English law. Its modern incarnation is found in the judgment of Lord Oliver in Reckitt and Colman Products Limited v Borden Inc [1990]. In that case, Lord Oliver said, “no one may pass off his goods as those of another,” and went on to set out the three main criteria which a claimant must prove to secure a successful claim.

Establishing a Case of Passing Off

Firstly, the claimant must prove the trade mark contains goodwill. Goodwill can be difficult to define and judges have used different factors to determine goodwill over time. A famous example of a name being shown to contain goodwill occurred in relation to a band called Liberty X. Formed originally as the band Liberty, the band were forced to amend their name after a judge found that it was too similar to a funk group that had achieved a degree of success a decade before the formation of Liberty X. The original band was considered to have residual goodwill in its name.

The second element of passing off requires some form of misrepresentation which causes confusion in relevant buying public. Using the Liberty example, the fact that the new band were operating in the same industry as the former group allowed the judge to conclude that the band could be misrepresenting itself to the public that it was the old band. Once the final letter X was added however, although the name was similar, the band had its own unique identity so were no longer liable for passing off as Liberty.

The final element of passing off is damage. The misrepresentation of someone else’s goodwill is not sufficient to constitute passing off on its own. To satisfy the elements of the tort, the misrepresentation must cause damage to the other party or by likely to cause damage to the other party. In the case of Stringfellow v McCain Foods (GB) Ltd [1984], an action for passing off involving a nightclub and a food product called Stringfellow chips failed because the public were unlikely to confuse a brand of chips with nightclubs and secondly because no damage was caused by the confusion.

Remedies for Unregistered Trademark Infringement

Businesses which believe its unregistered trademark rights are being taken advantage of unlawfully should act as soon as they have knowledge or suspicion of it. If there is a significant delay in bringing a claim against the party using the trademark, there is an increased risk that a Court will find that the business has acquiesced to the use, and undermine the claim for passing off. If the criteria are met and a claim for passing off is successful the following remedies may be sought:

  • an injunction to stop further use of the unregistered trademark;
  • financial damages to compensate for the loss of goodwill or a reduction in the sale of goods or services;
  • accounting for profit earned by the passing off of goods or services; and
  • an order for delivery-up and destruction of offending goods.

The latter remedies, damages and accounting for profit, are alternative remedies. In most cases damages are more commonly awarded. This is because in the final analysis, the sum of damages which would be awarded outstrips the sum of money which would be awarded with an account of profits

Brand Protection - Comments

The tort of passing off plays an important part of the arsenal of legal methods which may be used for protection of the reputation of businesses and brand protection. Although businesses are usually well-served by a registered trademark with a properly drafted specification of goods and services, passing off remains as a fall-back in situations where a business:

  • does not have registered trademark rights;
  • does have registered rights, and a competitor has attempted to design around registered trademark infringement;
  • a business does not have the rights under its registered trademark to reliably assert that the conduct of a competing business does not fall within the scope of infringement.
