Receiving a cease and desist letter can be unsettling, particularly when it alleges trade mark infringement. In the UK, these letters are common, but they are often misunderstood. Importantly, a cease and desist letter is not a court order and receiving one does not automatically mean you are in the wrong.
This guide explains what cease and desist letters mean under UK trade mark law, and how to respond sensibly and strategically.
What Is a Cease and Desist Letter in the UK?
In the UK, a cease and desist letter is a pre-action communication alleging that your activities infringe the sender’s legal rights, most commonly:
- Registered trade marks under the Trade Marks Act 1994
- Unregistered rights through passing off
- Domain name use that creates consumer confusion
Such letters are often sent before formal legal action and may later be relied upon as evidence that you were put “on notice”.
Does a Cease and Desist Letter Have Legal Force?
No.
A cease and desist letter has no automatic legal effect.
However, under the Civil Procedure Rules (Pre-Action Conduct and Protocols), parties are expected to attempt to resolve disputes before litigation. Failing to engage reasonably can have cost consequences if the dispute later reaches court.
Common UK Trade Mark Claims in Cease and Desist Letters
Most UK trade mark cease and desist letters rely on one or more of the following:
1. Trade mark infringement
Under sections 10(1)–10(3) of the Trade Marks Act 1994, infringement may be alleged where a mark is:
- Identical or similar
- Used for identical or similar goods/services
- Likely to cause confusion
- Taking unfair advantage of, or harming, a mark with a reputation
2. Passing off
Where no registered trade mark exists, the sender may rely on passing off, which requires proof of:
- Goodwill
- Misrepresentation
- Damage
Passing off claims are fact-specific and often harder to prove.
What Should You Do If You Receive a Cease and Desist Letter?
1. Do not ignore it
Ignoring a letter can escalate the dispute and weaken your position later.
2. Do not admit infringement
Avoid informal replies, apologies, or concessions before assessing the legal position.
3. Verify the sender’s trade mark rights
Check:
- Whether the mark is registered in the UK
- The classes of goods and services covered
- The filing and priority dates
- Whether the mark is vulnerable to challenge (e.g. non-use)
4. Assess the likelihood of confusion
UK courts consider:
- Visual, aural, and conceptual similarity
- Similarity of goods or services
- Average consumer perception
- Overall impression of the marks
5. Take early legal advice
Early advice can often resolve matters quickly — sometimes with a single, well-judged response.
How Can You Respond?
Depending on the strength of the claim, responses may include:
- Compliance (where infringement is clear)
- Without prejudice negotiations
- Challenging the legal basis of the claim
- Requesting further information
- Proposing coexistence or limitations
A measured response often prevents unnecessary escalation.
What You Should Avoid If You Receive a Cease and Desist Letter
- Ignoring deadlines set out in the letter
- Responding emotionally or defensively
- Rebranding before assessing your position
- Making public statements about the dispute
- Admitting liability without advice
Poor handling can expose you to unnecessary risk.
What If You Are Sending a Cease and Desist Letter?
In the UK, cease and desist letters must be handled carefully.
Under the unjustified threats provisions of the Trade Marks Act 1994 :
- Making unjustified threats of infringement proceedings can expose the sender to legal action
- Threats to secondary infringers (such as distributors) are particularly risky
Letters should be accurate, proportionate, and strategically drafted.
