What we searched, and when

Most trademark search tools tell you how many marks they hold and never tell you the date. An undated search is the one you cannot check. So here is ours, live, on every page load.

Indexed 3 days ago. Last rebuilt 2026-10-01.

/api/corpus returns the same figures as JSON, so you can check them without taking our word for it.

What this does not cover

Filings newer than the rebuild date. The USPTO publishes daily; we rebuild on a schedule, so there is always a window we have not seen.
Common-law marks. Unregistered rights can block you and appear in no register at all.
State registrations and foreign filings. Outside this index.
Design marks. We analyse wording; logos are assessed differently.

This is why the product prepares rather than files, and why every report says to confirm with a licensed trademark attorney.
