A Letter of Protest is a written statement that is filed with the United States Patent and Trademark Office (USPTO) to express objections to the registration of a trademark. The letter may be filed by someone who believes that the proposed trademark is too similar to their existing trademark or otherwise violates their rights.
The USPTO will consider a Letter of Protest during its examination of the trademark application and may use the information contained in the letter to support a refusal to register the trademark. The letter may also be considered as evidence in any future legal proceedings related to the trademark.
In order to be effective, a Letter of Protest must be specific and provide evidence to support the objections raised. This may include evidence of the similarity between the marks, evidence of prior use of the mark, or other relevant information.
It’s important to note that filing a Letter of Protest does not guarantee that the trademark application will be refused. Ultimately, it is up to the USPTO to determine whether the trademark can be registered.
