UK Trade Mark Owner Search

Search the UK trade mark register free at the Intellectual Property Office. You can search by mark, by owner or by number, and the register names the registered proprietor. Just don’t read a trade mark record as a statement of who owns the business: the proprietor may be a dormant holding company, and the brand may be operated by a licensee or franchisee entirely.

Search the UK trade mark register

The IPO’s search service covers registered UK trade marks and pending applications. Three approaches:

• By word or phrase, to find marks matching a brand name
• By owner, to list everything a company holds
• By number, where you already have the registration

A record gives you the proprietor’s name and address, the filing and registration dates, the goods and services classes, the status, and the representative on record.

Find trade marks by owner

Owner search is the most useful for ownership research: it shows a group’s whole UK portfolio in one view, which often exposes structure that is otherwise invisible. Brands you assumed were separate businesses turn out to sit under one proprietor.

Search on variants. Groups file under slightly different names, and proprietor names change on assignment without every record updating at once. Search the trading name, the legal entity name, and any former names from Companies House.

Trade mark owner vs brand owner

This is the distinction that matters most, and it is routinely collapsed.

The registered proprietor owns the registration — a legal right to stop others using the mark. It is frequently an IP holding company that does nothing else.

The brand operator runs the business trading under the name. Often a different company in the same group.

A licensee has permission to use the mark. A franchisee is a licensee: the shop with the sign above the door may be independently owned and merely licensed to use the brand.

The parent company sits above whichever of these entities you have found, and the ultimate owner above that.

All five can be different companies. “Who owns this brand?” is genuinely ambiguous until you say which you mean.

International marks covering the UK

Not every mark protected in the UK sits on the UK register as a domestic filing. International registrations designating the UK are made through the WIPO Madrid System and appear on the IPO register as designations, with WIPO holding the underlying record.

EU trade marks are their own history. EUTMs stopped covering the UK after the transition period, and comparable UK rights were created automatically from existing EUTMs. Those comparable marks are on the UK register, but their record traces back to an EU filing — worth knowing when dates look inconsistent.

How to verify rights ownership

1. Search the IPO register for the mark and note the proprietor exactly as recorded.
2. Check the status — registered, pending, expired, or surrendered. An expired mark confers nothing.
3. Check the classes. A mark registered for software says nothing about the same name on clothing.
4. Look at the filing history for assignments and licences; ownership changes are recorded there.
5. Look the proprietor up at Companies House to place it in a group.
6. Check WIPO where an international registration is involved.

Common limitations

The register records registered rights only. Unregistered rights exist in the UK — a business with genuine goodwill in a name can act in passing off without any registration — so an empty search does not mean a name is free.

Assignments can lag. A mark sold months ago may still show the seller, so corroborate against company filings or announcements where it matters.

And a registration is not a business. It tells you who holds a right in a name. Who runs the company, employs the staff and takes the profit is a separate question, answered at Companies House.
