Someone Else Is Trading on Your Name: A Small Business Guide to Passing Off and Trade Marks

Few things sting quite like discovering a competitor has borrowed your identity. A bakery in one market town spots its name — or something close enough — on a rival's delivery van two villages over. An online seller finds their best-reviewed product listed under a near-identical name by a dropshipper they have never dealt with. The immediate reaction is usually indignation; the second reaction, more usefully, should be a plan.

This article sets out what protection English law actually offers a small business that has not registered a trade mark, how to prepare for that conversation with a rival, and when a firm letter achieves more than an application to court.

What Passing Off Actually Requires

The United Kingdom recognises two distinct routes to protecting a business name or brand. The first, registration under the Trade Marks Act 1994, confers statutory rights. The second, the common law action of passing off, is available to anyone who has built a reputation — but only if they can satisfy a three-part test that the courts have refined over more than a century.

In short, you must establish:

• Goodwill — a recognisable identity (name, logo, get-up, even distinctive packaging) that the buying public associates with your business;
• Misrepresentation — that a competitor has made a false statement or created a false impression, deliberately or otherwise, suggesting a connection with your business; and
• Damage — that this misrepresentation has caused, or is likely to cause, you harm: lost custom, diluted reputation, or association with inferior goods.

All three elements must be present. A copycat trading in Manchester will struggle to mislead anyone if your business is a single shop in Truro with no online presence. Conversely, a nationwide e-commerce seller may find that geographic boundaries matter far less than they assumed.

The Evidence File: Build It Before You Need It

Passing off claims are won and lost on evidence of goodwill. The business that can produce dated records of its trading history, marketing spend, customer reviews, press coverage and social media following is in a categorically stronger position than one relying on assertion alone.

A practical evidence file should include:

• Evidence of first use of the name or logo, and continuous use since;
• Sales figures and turnover attributable to the brand;
• Screenshots of the copycat's website, listings or social accounts, ideally captured with dates visible;
• Examples of actual confusion — emails or messages from customers who mixed the two businesses up are worth their weight in gold;
• Any customer enquiries directed to you by mistake, or complaints intended for the other party.

Screenshots are perishable. If a rival changes their branding overnight, an early capture preserved with a date and time may be the only proof that the confusion ever occurred.

The Unregistered Reality: What You Do Not Have

It is worth being candid about the limits. Without registration, your rights are tied to the specific identity the public recognises — not to an idea, a style, or a general trading concept. A competitor may lawfully open a bakery, use similar colours, and sell comparable products, provided they do not trade on your name or get-up in a way that misleads the public.

Registration, by contrast, gives you a property right enforceable against anyone using an identical or similar mark for similar goods, regardless of goodwill or confusion in a particular case. For businesses with growth ambitions — franchising, online sales, expansion beyond the home patch — registration is usually the more economical form of insurance. It is also considerably cheaper than litigation.

The Letter Before the Claim

For most small businesses, the sensible first step is a carefully drafted letter before action. Its purpose is twofold: to put the rival on notice of your rights and require them to stop, and to demonstrate — should matters escalate — that you acted reasonably and proportionately.

A well-constructed letter will typically:

• Identify the goodwill relied upon and the evidence supporting it;
• Set out precisely what the rival is doing and why it amounts to misrepresentation;
• Require specified steps within a defined period — ceasing use of the name, withdrawing listings, providing a written undertaking;
• Reserve your position on costs and further remedies.

The tone matters. An aggressive letter from an unrepresented business owner can invite a counter-claim or, worse, a threat of unjustified threats under trade mark law if the wording is careless. A measured letter drafted with legal advice frequently achieves more, because it signals that the matter will be pursued properly if ignored.

When Court Becomes the Answer

Some copycats simply do not respond to correspondence. Where the damage is significant — a competitor diverting trade online, or using a confusingly similar name in your own territory — proceedings for passing off may be justified. The courts can grant injunctions requiring the infringer to stop, order delivery up or destruction of infringing materials, and award damages or an account of profits.

Litigation is expensive, and costs can quickly outstrip the sums in dispute. That is precisely why the earlier steps matter: a documented evidence file, a proportionate letter, and an early assessment of the strength of your claim all reduce the risk of a costly misjudgement. Interim injunctions — emergency orders obtained before a full trial — exist, but the courts expect applicants to have moved promptly once they became aware of the problem.

Practical Takeaways

For any UK small business, three habits are worth adopting today. First, keep dated records of your branding, marketing and reputation — goodwill is proven, not presumed. Second, consider trade mark registration for the name and logo you have invested in; the filing fee is modest against the cost of a dispute. Third, if a copycat appears, take advice before firing off an angry email — the first letter you send will be read again, possibly by a judge.

Your name is often the most valuable asset a small business owns. The law will protect it, but only for those who can prove it is theirs.
