The ultimate guide to Passing Off

What is Passing Off?

Passing off is a form of common-law unfair competition protection in the UK. It allows a business (the claimant) to sue when another party (the defendant) misrepresents their goods or services as being those of the claimant (or endorsed by/connected with them), thereby causing damage to the claimant’s business goodwill.

In other words: if you’ve built up a reputation (goodwill) in your brand/name/get-up and someone else trades in such a way that the public is likely to be misled into thinking their goods or services are yours, you may have a passing off claim.

Unlike registered trade mark infringement, passing off does not require you to have a registered trade mark. It protects unregistered rights (goodwill) and can be used to catch “look-alikes” or misrepresentations outside the scope of a trade mark registration.

The Core Legal Elements

The courts generally require three elements for a passing off claim to succeed:

1. Goodwill (or reputation) in the claimant’s goods / services
   The claimant must show that they have established a reputation or connection with the trading name, mark, packaging or get-up in the minds of the relevant public. “Goodwill” is defined as “the benefit and advantage of the good name, reputation and connection of a business”.
2. Misrepresentation by the defendant to the public
   The defendant must have made a representation (express or implied) which leads or is likely to lead the public to believe that the goods/services of the defendant are those of the claimant (or are connected with the claimant). Intent is not necessary — the key is whether the misrepresentation is likely.
3. Damage (or likelihood of damage) to the claimant’s goodwill
   The claimant must show that they have suffered (or are likely to suffer) damage as a result of the misrepresentation. This can include lost sales, damage to reputation, or erosion of the distinctive identity of the business.

Why It Matters / Practical Implications for Businesses (especially SMEs)

• Protection without registration: If you haven’t (yet) registered a trade mark, passing off gives you a route to protect your brand or get-up against copycats.
• Beyond names/marks: It can cover more than just names — e.g., packaging, trade dress (look of the product), endorsements (celebrity/image), get-up of goods/services.
• High evidential burden: It can be more difficult and risky than trade mark infringement, because you must prove goodwill, misrepresentation, and damage. SMEs may need to be rigorous in gathering evidence (e.g., customer surveys, sales data, brand awareness) early.
• Watch for lookalikes: If a competitor uses a name, get-up or branding close to yours (especially in the same market), that can trigger risk of passing off. Vigilance is important.
• Remedies: If successful, you can seek injunctions (to stop the defendant), damages, accounts of profits, destruction of offending materials etc.
• Complement to trade marks: Even with a registered trade mark, passing off can complement your protection (for example, you might catch aspects the registration doesn’t cover). For SMEs, a combined approach of trade mark registration + brand protection plan is wise.

Key UK Cases

Here are some landmark UK cases on passing off — useful for understanding how the law has been applied.

1. Reckitt & Colman Products Ltd v Borden Inc (“Jif Lemon” case, 1990)

• This is one of the leading decisions by the UK House of Lords on passing off.
• Facts: The claimant sold lemon juice in a plastic container shaped like a lemon under the trade name “Jif”. The defendant started to sell lemon juice in similar lemon-shaped packaging.
• Decision: The House of Lords upheld the injunction in favour of the claimant. The “get-up” (shape + packaging) had become distinctive of the claimant’s product and the defendant’s use was likely to mislead. Lord Oliver reaffirmed the three-part test of passing off: goodwill, misrepresentation, and damage.
• Significance: Shows that passing off can protect distinctive product packaging or get-up (not just names/logos) where it acquires recognition in the market.

2. Erven Warnink BV v J Townend & Sons (Hull) Ltd (1979)

• Facts: Warnink sold a Dutch liqueur “Advocaat” made in a particular way. Townend sold a similar drink called “Keeling’s Old English Advocaat”. The claimant argued misrepresentation of character/quality of goods.
• Decision: The House of Lords recognised an “extended” passing off cause of action, beyond simply confusion as to origin: where goods are sold under a name that suggests a certain character or quality (e.g., “Advocaat” meaning a specific type of liqueur) the protection can apply. The five-element test (from Lord Diplock) was laid out.
• Significance: Expands passing off’s reach into cases of mis‐representation of quality/character, not only origin.

3. Irvine v Talksport Ltd (2002/2003)

• Facts: The claimant, a famous Formula 1 driver Eddie Irvine, brought a passing off claim against a radio station (Talksport Ltd) which used a manipulated photograph of him holding a radio bearing the station’s name, thereby creating the impression he endorsed the station.
• Decision: The Court of Appeal held that a passing off action could succeed in a “false endorsement” case. The claimant had goodwill in his reputation; the defendant’s brochure misrepresented his endorsement; and there was likely damage to his goodwill.
• Significance: Demonstrates that passing off can protect personality (image/name) rights in the UK (through goodwill) even though there is no standalone “image right”.

Some Practical Tips & Points for Businesses

• Build and record your goodwill early — Even if you don’t have a registered trade mark, clear evidence of use, recognition, sales, advertising, customer base will help demonstrate goodwill.
• Be distinctive — The more your name/logo/get-up is recognised by your market, the stronger the goodwill. Generic or purely descriptive terms are weaker.
• Avoid misrepresentation — If you use a style/look/name that’s confusingly similar to an established business, you risk being sued for passing off. This includes copycats of branding, packaging, endorsement implications, domain names.
• Act quickly on issues — Delay might weaken your case (evidence may go stale, confusion may persist).
• Gather evidence of confusion or potential damage — Examples: mis-directed sales, customer complaints, poor reviews for the copy, lost business, association with inferior goods.
• Use passing off in conjunction with trade mark registrations — While passing off protects unregistered rights, trade marks provide clearer and more predictable protection. Combining the two gives stronger brand defence.
• Consider online scenarios — The same principles apply to e-commerce, domain names, online marketplaces (misleading domain names, look-alike sites).
• Enhance your brand hygiene — Choose a distinctive brand name/ logo, consistently use it, guard your packaging/look, monitor for copycats.
• Get legal advice early — Because passing off is fact-sensitive and evidentially demanding, having early legal input is important.

Limitations & What to Watch Out For

• Passing off is fact-specific: success depends heavily on evidence of goodwill and misrepresentation.
• It can be more costly and uncertain than trade mark-based claims, due to the higher burden of proof.
• The protection is generally limited to the region and customer base where your goodwill exists (local, national).
• Functionality issues: If the get-up/packaging is driven by functional requirements (i.e., shapes necessary for technical reasons) then protection may fail (as distinctiveness may not be present or monopoly not justified).
• Delay and acquiescence can be harmful (if you allow confusion to persist without action).
• Passing off may not always be appropriate for purely “look-alikes” if there is no goodwill or misrepresentation causing damage.

Summary

In summary: the tort of passing off plays a vital role in protecting brand identity, reputation and goodwill in the UK — especially for businesses that may not yet have registered trade marks or have goodwill in unregistered get-up or endorsements. The classic three-element test (goodwill + misrepresentation + damage) remains the cornerstone, as reaffirmed in landmark cases such as Reckitt & Colman and Irvine v Talksport.

For SMEs, the key is to protect your brand consistently, monitor the market for confusingly similar trading, and be ready to gather evidence and act if you believe a competitor is passing off.
