  1. The name is too short
  2. It is too similar to a registered mark ✔
  3. The owner has no website yet

Why: If customers would likely think your goods or services come from the same source as someone else's, the USPTO refuses the mark. That is why the USPTO says to run a clearance search in its Trademark Search system before you pick a name.

Huh, didn't know that: The USPTO only checks its federal database; searching state trademark databases and the internet is your job.
