A Letter of Protest is filed with the United States Patent and Trademark Office (USPTO) for the purpose of notifying the USPTO that federal registration of a mark in a pending trademark application should be refused. It is essentially a way for a third-party (referred to as the “protestor”) to aid in the review of a trademark application in a manner that preserves the integrity and objectivity of the application examination process. The name of the protestor and/or its legal representative is kept confidential so that the examining attorney remains unbiased when reviewing the evidence submitted with the Letter of Protest. In addition, the Letter of Protest itself is not entered into the public application record, but anybody who wishes to request a copy can do so by contacting the USPTO via email.
