Trademark search that scores the risk for you
Enter a brand name. Avanti Notum searches the UK trademark register and returns a ranked list of similar marks, each scored by sound, spelling and meaning. Each result gets a clear high, medium or low conflict-risk indicator, and the list is ranked so the marks that matter most are at the top. No scrolling through hundreds of irrelevant results. No legal jargon. Just a clear picture of where the risk sits.
High conflict risk
Two names spelled differently can still clash if they sound alike. Avanti Notum scores phonetic similarity using established sound-matching algorithms.
Searching a trademark register tells you what exists. Not what matters.
More than 150,000 trademarks are applied for in the UK every year — most of them by small businesses naming a company, a product or a brand for the first time.
When they go to check whether a name is clear, they face two poor options. Free government search tools return a raw list of results with no sense of which ones are a genuine conflict — so they scroll, get overwhelmed, and either file blind or give up. The alternative is a solicitor's preliminary search at £200–500, which most cannot justify before they even know whether there is a problem.
A trademark application that runs into a conflict is not just a £170 fee lost. It can mean rebranding a launched business, scrapping printed materials, or a cease-and-desist letter after the brand is already in use.
The hard part of trademark search has never been finding marks. It is knowing which of them could block you. That is the gap Avanti Notum was built to close.
Three steps to a clear answer
The only thing Avanti Notum needs is a brand name.

Free tools leave you to work it all out yourself. Enterprise platforms are built — and priced — for City law firms with global portfolios. Avanti Notum is for everyone in between: the founders, businesses and advisers who file most of the UK's trademarks.
A search tool, not a law firm
We want to be plain about this, because it matters. Avanti Notum is a trademark search and monitoring tool. It scores how similar marks are and flags potential conflicts. It does not provide legal advice, and it cannot tell you whether your trademark will be accepted for registration.
What it does is give you a clear, scored picture of the conflict risk — fast and affordably — so you can make an informed decision and, for the name you choose to file, take a well-prepared shortlist to a qualified trademark attorney. Avanti Notum does the first 45 minutes. A professional does the part that needs professional judgement.
That honesty is built into the product. We give you a confidence score, never a verdict.
Start free. Upgrade when it pays to.
Avanti Notum is free to start — three searches a month, no card, no time limit. When you need more searches, conceptual scoring, reports or monitoring, paid plans begin at £29 a month, including VAT. Accountancy firms and agencies have plans built for multi-client work, and there is an Enterprise tier with API access for high-volume professional users.
