Terms of service
Last updated · Trademark Search is operated by Prometheus Labs, Kitchener, Ontario, Canada ("we", "us").
1. The service
Trademark Search searches public U.S. (USPTO) and Canadian (CIPO) federal trademark records and reports factual matches: identical, similar-looking and similar-sounding trademarks. The free search shows counts and the 3 closest trademarks with their status. The Clearance Report adds owner, number, class, and goods and services details from the official records.
2. Not legal advice
Trademark Search is a search tool, not a law firm, and nothing on this site or in a report is legal advice. Results are factual matches against public records and do not determine whether a name is available to use or register. Using the service creates no lawyer-client relationship. For a legal opinion on adopting or registering a name, consult a licensed trademark lawyer or agent.
3. What the search covers, and what it does not
The database holds registered and pending federal trademarks from the USPTO and CIPO, loaded from official government data files, plus records that recently became inactive. It does not include U.S. state registrations, common-law (unregistered) trademarks, other countries' registers, or logo and design elements. Government data can lag or contain errors, and every search is a snapshot of the records loaded at the time it runs. For a very common name, a search can reach its limit for a matching rule. The Clearance Report checks registered and pending records first, and the free search checks the newest records first. "Nothing found" is never a promise that a name is available.
4. Purchases
- Clearance Report (US $39, one time). Delivered on screen and by email with the full report attached, usually within minutes of checkout. The report is dated: your link keeps showing it as it was prepared at purchase, and you can also re-run it against the current records.
Prices are in US dollars; applicable taxes are added at checkout. Payments are processed by Stripe.
5. Refunds
Clearance Reports are digital reports delivered when you buy them, so purchases are not refundable. If we cannot deliver the report you paid for, email hello@prometheuslabs.ca and we will fix it or refund you. Nothing in this section limits your rights under consumer protection law.
6. Acceptable use
Do not scrape or bulk-harvest results, resell the service, probe it for vulnerabilities, or use it to send unsolicited messages. The underlying trademark records are public and available from the USPTO and CIPO at source.
7. Service quality and liability
The service is provided "as is", without warranties of accuracy, completeness, or fitness for a particular purpose. To the maximum extent permitted by law, our total liability for any claim is limited to the amount you paid us in the 12 months before the claim, and we are not liable for indirect or consequential damages or for decisions made using search results.
8. General
We may update these terms; material changes will be posted here with a new date. These terms are governed by the laws of Ontario and the federal laws of Canada applicable therein. Support is available at hello@prometheuslabs.ca.
