Check the handle everywhere it matters — in one go.

The catch

An open handle isn’t a clear name

Handles are a material signal — useful, never decisive. A name can be open on every platform and still belong to someone as a US trademark, which is the only thing that can actually stop you. Check the handle here; clear the name before you build on it.
