  1. is identical with a trademark already registered by another person; or
  2. is so similar to a registered trademark of another person that the public might be confused or misled as to the owner or origin of the goods, and such application is for goods of the same class or for goods of a different class found by the Registrar to be of the same character, he shall not register such trademark.
