Check your listing for trademark risks.
Find the dangerous words. Then fix them.

Sample report — a real test result

Every flagged term expands to the full registry record — number, owner, classes — plus a safer way to rewrite it.

How it works

1. Paste. Drop in a title, description and tags — or upload a CSV with your whole catalogue.

2. We scan. Every word and two-word phrase is checked against three live registries and a 2,200-term high-risk list.

3. You get a verdict. Red / yellow / green for every term, with the registration behind it and a safer rewrite — before the listing goes live, not after a takedown.

Three registries, one scan

• United States — USPTO registrations and applications.
• European Union — EUIPO trade marks covering all 27 member states.
• United Kingdom — UK IPO registrations.

Most checkers cover one registry. One scan here covers all three, and matches are weighed by product class — not just by name — so ordinary words in unrelated classes don't cry wolf.

Near-matches count too: spelling variants and sound-alike terms are scored, not just exact words.

More than trademarks — policy checks too

A listing can be pulled without any trademark in it. The same scan also checks title, description and tags against marketplace policy traps:

• Prohibited items — products and materials the platform bans outright.
• Health claims — cure, treat and therapy wording you can't substantiate.
• Counterfeit language — “replica”, “inspired-by” and dupe wording.
• Listing practices — keyword stuffing and misleading descriptions.

One paste, both kinds of trouble flagged — before the platform's own filters find them.

Check a shop name before you commit to it

Thinking of a name for a new shop — or wondering if the one you have is safe? Run it through the same checker:

• Live marks in the US, EU and UK, with the classes they actually cover.
• A name trademarked for candles won't scare you off a jewellery shop — you see the classes, not just the name.
• Sound-alike and spelling variants included.

Cheaper to learn now than after the packaging and 500 listings already carry the name.

New trademarks appear every day. We keep watching.

A clean scan today can collide with a trademark filed tomorrow. That is why the check doesn't end at publish:

• Your listings are re-scanned every week.
• A new registration matching your terms triggers an email alert.
• Every scan is kept in your history, dated and reproducible.

You find out from us — not from a marketplace takedown notice.

Watch your own brand, not just your listings

Your name can be copied as fast as you can borrow someone else's. Add your brand and product names to a watchlist:

• New trademark applications matched by spelling, sound and goods.
• Every conflict shows its opposition deadline, counted down.
• Copycat listings on marketplaces, flagged with the evidence attached.

You hear about it while you can still act — not from a confused customer.

Already taken down? Appeal letters, drafted

If a listing is removed anyway, don't start from a blank page. Paste the removal notice and Marklert works out which kind it is:

• Trademark complaint, DMCA notice, or platform policy removal.
• A ready-to-send letter that answers that specific notice, in the platform's own process.
• What to fix in the listing before you ask for it back.

Prevention first — and a parachute for when prevention wasn't enough.

Questions

What does free cover? Five scans a day with full verdicts. Subscribing adds bulk scans, monitoring and alerts — the checking itself is the same.

Why not check the registries myself? You can — one word at a time, one registry at a time. Marklert checks every word and phrase against all three at once, and keeps re-checking after you publish.

Where does the data come from? Official sources only: USPTO, EUIPO and UK IPO, refreshed on each registry's own update cycle.

Clean scan = guaranteed safe? No. This is a risk screen, not legal advice. It catches registered word marks; image marks and unregistered rights can still apply.

How do I cancel? One click in settings. The plan runs to the end of the paid period, then drops to free. Refunds follow the refund policy in the footer.
