Receiving a cease and desist letter from Marks & Clerk can be an unsettling experience, particularly if it alleges that your business has infringed someone else’s intellectual property (IP) rights.
Your first instinct may be to ignore it, respond immediately, or assume you’ve done something wrong. However, none of these are likely to be the best course of action.
The important thing is to understand what the letter means, what rights are being asserted, and what options are available to you before taking any action. This is where our friendly and approachable IP lawyers are here to help you.
In this guide, our UK IP firm explain why you may have received a letter from Marks & Clerk, what you should do next, and how specialist intellectual property advice can help.

Who Are Marks & Clerk?
Marks & Clerk is one of the UK’s largest intellectual property firms, with offices across the UK and around the world. They advise businesses, universities and global brands on protecting and enforcing intellectual property rights, including trade marks, patents, registered designs and copyright.
If you’ve received correspondence from Marks & Clerk, it is likely because they are acting on behalf of one of their clients who believes their intellectual property rights have been infringed.
It’s important to remember that the letter has been sent on behalf of a rights holder. Receiving one does not automatically mean you have infringed their rights, but it does mean the allegation should be taken seriously.
Why Have I Received a Letter from Marks & Clerk?
There are many reasons why Marks & Clerk may contact a business or individual.
Common examples include allegations relating to:
- Trade mark infringement
- Patent infringement
- Copyright infringement
- Registered or unregistered design rights
- Passing off
- Domain name disputes
The letter may ask you to stop using a business name or logo, remove products from sale, change branding, transfer a domain name, provide information about your activities, or sign legal undertakings.
Exactly what is being requested will depend on the circumstances and the intellectual property rights involved.
What Should You Do If You Receive a Letter from Marks & Clerk?
Although receiving legal correspondence can feel intimidating, the most important thing is to remain calm and avoid making rushed decisions.
Before responding, you should:
- Read the letter carefully.
- Identify exactly what rights are being relied upon.
- Keep copies of all correspondence.
- Avoid admitting liability or making promises before obtaining advice.
- Seek advice from an experienced intellectual property professional at Panoramix IP.
Every dispute is different. In some cases, the allegations may be well founded. In others, there may be valid arguments available to defend your position or negotiate a practical commercial solution.
Understanding the strength of the claim before responding can make a significant difference to the outcome.
Should You Ignore a Letter from Marks & Clerk?
You should not ignore a letter from Marks and Clerk.
Ignoring correspondence relating to intellectual property rights can allow the dispute to escalate unnecessarily. If the matter cannot be resolved, the rights holder may decide to pursue legal proceedings.
That does not mean court action is inevitable. Many intellectual property disputes are resolved through negotiation once both parties have had the opportunity to understand the legal and commercial position.
Responding appropriately – and with the benefit of specialist advice – can often help avoid unnecessary cost and disruption.
