How different does one trademark have to be from another?

After an application is filed, the assigned examining attorney will search the USPTO records to determine if a conflict, i.e., a likelihood of confusion, exists between the mark in the application and another mark that is registered or pending in the USPTO. The USPTO will not provide any preliminary search for conflicting marks before an applicant files an application. The principal factors considered by the examining attorney in determining whether there would be a likelihood of confusion are:

  • the similarity of the marks; and
  • the commercial relationship between the goods and/or services listed in the application.

To find a conflict, the marks do not have to be identical, and the goods and/or services do not have to be the same. It may be enough that the marks are similar and the goods and/or services related.

If a conflict exists between your mark and a registered mark, the examining attorney will refuse registration on the ground of likelihood of confusion. If a conflict exists between your mark and a mark in a pending application that was filed before your application, the examining attorney will notify you of the potential conflict. If the earlier-filed application registers, the Examining Attorney will refuse registration of your mark on the ground of likelihood of confusion.
