Trademark scam letters and fake invoices: how to spot them

By trademarked.uk editorial · Last reviewed June 2026

If an official-looking invoice has arrived about your trademark — asking for a few hundred pounds to “register”, “publish”, “renew” or “protect” it — treat it as a scam until proven otherwise. Don’t pay it, and don’t reply. These letters carry your real trademark details and look convincing, but they come from private companies with no connection to the Intellectual Property Office. The IPO does not cold-contact you demanding payment.

Here’s why you’re getting them, how to recognise one in seconds, and exactly what to do.

Why you’re being targeted

When you apply for a trademark, your details go on the public register — your mark, the classes, your name and address, and the filing date. That’s by design: it’s what lets others check the register and object to conflicting marks. But it also means anyone can harvest your details the moment you file.

Scammers do exactly that, then post an invoice that quotes your real application back to you. The realistic timing: an official-looking letter often lands within weeks of filing. Real details are what make these convincing — they are not proof the letter is genuine.

The IPO never sends you an unsolicited invoice. It only charges for actions you (or your attorney) started — like an application or a renewal you requested. Any cold letter offering “registration”, “publication in a directory”, “monitoring” or “international protection” for a fee is not from the IPO.

Five red flags

  1. Urgency. A short deadline — “pay within 7 days” — designed to make you act before you check. Official deadlines are communicated calmly and well in advance.
  2. A fee that doesn’t match. The amount is usually anywhere from a few hundred to a few thousand pounds — far above the real official fees — for a “service” you never requested.
  3. A name that’s almost right. Titles built to echo real bodies — a letter off from EUIPO, a word added to WIPO. If it’s not the IPO (UK), the EUIPO (EU) or WIPO (international), be suspicious.
  4. An overseas bank account for what’s dressed up as a UK or EU service.
  5. A tiny disclaimer. Buried at the bottom, in pale small print, a line admitting the organisation isn’t affiliated with any official body. If you have to read the fine print to find that out, that’s your answer.

How to reduce the letters

You can’t make your filing private — publication is part of how the system works — but you can blunt the impact:

One reassuring note: searching the register is private — running a check on a name exposes nothing about you. The exposure comes only when you file. So check freely, file when you’re ready, and bin the fake invoices that follow.

Frequently asked questions

Why did I get an invoice with my real trademark details on it?
Because the trademark register is public. Once you apply, your mark, classes and filing date are visible to anyone — and scammers harvest those details to make their letters look genuine. Real details on a letter do not make it official.
Is a trademark scam letter illegal?
Many can breach the Consumer Protection from Unfair Trading Regulations 2008, and Trading Standards can act against them — but the senders are often based abroad and change names constantly, which makes enforcement hard. Either way, these are unsolicited offers and you are under no obligation to pay.
Does the IPO send invoices for trademark services?
The IPO does not cold-contact you demanding payment. It only takes fees for actions you or your representative started. An unsolicited invoice for 'registration', 'publication', 'monitoring' or 'protection' in some directory is not from the IPO.
I've already paid one — can I get my money back?
The IPO says it's highly unlikely you'll recover the money, but act fast. Contact your bank immediately; credit-card payments may be protected under Section 75 of the Consumer Credit Act. Report it to the IPO and to Action Fraud, and keep all the paperwork.
How do I report a misleading trademark invoice?
Send a copy to misleadinginvoices@ipo.gov.uk and the IPO will respond. Also report it to Action Fraud at actionfraud.police.uk or 0300 123 2040, and to your local Trading Standards.
I have a trademark attorney — should I worry about these letters?
If you're professionally represented, all genuine correspondence about your mark should go through your attorney. A letter that comes straight to you, bypassing them, is an immediate red flag — forward it to them before doing anything.
