It is dated, printable, and emailed to you with the full report attached. Usually delivered in minutes.

Common questions

Is the free search really free?

Yes: unlimited searches, no account, no sales calls. It uses the same matching engine as the paid report. It shows how many similar trademarks it found and the 3 closest, with their status, country and filing year.

What does the US $39 Clearance Report add?

Depth and a document. The report searches deeper and lists up to 300 matches, closest first, across every goods and services class. Each one comes with its status, owner, serial and registration numbers, filing date, classes, and goods and services. You see it on screen right after checkout, and we email it to you with the full report attached as a file you can keep. The report is dated, and your link keeps showing it as it was on the day you bought it.

Which trademarks do you cover?

Registered and pending federal trademarks from the USPTO (U.S.) and CIPO (Canada), plus recently inactive ones: millions of records, loaded from the official government data files. U.S. state and common-law trademarks are not on the federal registers, so no register search includes them. Logos and design elements are not searched.

Is this legal advice?

No. We report factual matches from official government records and leave the judgment to you. For a legal opinion on whether a name is available, talk to a trademark lawyer or agent. You can share your Clearance Report with them.

Refunds?

No. The Clearance Report is a digital report delivered when you buy it, so purchases are not refundable. If you did not receive your report, email hello@prometheuslabs.ca and we will fix it or refund you. Nothing here limits your rights under consumer protection law.
