MarkAlarm

Know when someone files a US trademark that looks like your brand.

MarkAlarm reads every new USPTO trademark application, every business day, and emails you a plain-English match report when a filing looks similar to a name you're watching — while there's still time to respond. Information, not legal advice.

Free check: has anyone filed something like your mark recently?

Scans the USPTO applications currently indexed and shows why each match fired. No signup required.

Optional — what do you sell?

How it works

1
Add the brand names you want watched (with goods/services classes if you know them — optional).
2
Every day we score all new federal applications against your marks: spelling, sound, word overlap, and class overlap — each alert shows its full scoring breakdown and links the official USPTO record.
3
Similar filing → immediate email. Quiet week → a short Monday “all clear,” so you know the watch is alive. That's the whole product.

Honest answers

What exactly do you monitor?

New federal trademark applications published in the USPTO's daily application data. We do not monitor state registrations, common-law (unregistered) use, business-name registries, or foreign filings.

Is this legal advice?

No. MarkAlarm is an information service: we surface filings and similarity scores with links to the official record. Whether to oppose a filing is a legal decision — if an alert worries you, a trademark attorney is the right next step, and you'll arrive with the filing already in hand.

Will I get spammed with false alarms?

You'll get high/medium-similarity alerts immediately; weak partial matches don't interrupt you — they're just counted in your weekly summary. Every alert shows why it fired (spelling, sound, word, class overlap), so you can tune or remove watches in one click.

Do I need a registered trademark to use this?

No — many subscribers watch names they use but haven't registered, so they learn immediately if someone else moves to register it.

How do I cancel, and can I get a refund?

Email support from your subscription address and we'll cancel it for you, or use the billing link in your Stripe receipt email. Cancelling takes effect at the end of the year you've already paid for, and you keep access until then. If it's not what you expected, email support within 30 days of your first purchase for a full refund — one per person or business. A refund ends the subscription and monitoring stops when it's issued, so it's the money back rather than the remaining year. Card payments are processed by Stripe; we never see your card details.
