A person types a name at https://joinopenfile.com/trademark-search to search live USPTO records and check it for common refusal risks. It's free, with no sign-up.

An agent can run the same checks with the `screen_mark` and `search_marks` tools at https://mcp.joinopenfile.com. Neither is a legal opinion, so never tell someone a name is safe to use.
