Brand Name Check

Check whether a brand or product name is registered as a domain and whether similar US trademarks exist.

Brand Name Check turns a name into a domain label and looks it up across a list of top-level domains using RDAP, the registry lookup protocol. For each domain it reports registered (with registrar, creation and expiry dates), likely available, or unknown when the registry could not be reached or does not offer RDAP. Optional variations add a hyphen, "get" and "try" prefixes, and "app" and "hq" suffixes.

When a USPTO API key is configured on the server, the connector also searches US trademark records for identical or similar wording and returns serial number, mark, owner, status, classes and a link to the USPTO record. When it is not configured, it returns a ready search link instead and states that the trademark search was not run.

Results are indications, not legal advice. A domain shown as likely available must be confirmed at a registrar, and a trademark search of one database does not replace a clearance search by a qualified attorney.

Example prompts
