In case of an assignment filed on paper, what document must be included showing the transfer?

The correct response highlights the necessity of including a specific document in an assignment when filed on paper, which is a document indicating the transfer of ownership. This document is crucial because it serves as the official record that demonstrates the change in ownership of the trademark. Such documentation needs to clearly illustrate the relationship between the previous owner and the new owner, validating the transfer in the eyes of the trademark office.

For an assignment to be processed correctly, it must provide a verifiable indication that ownership rights have been duly transferred. This can include elements like the date of the transfer, signatures from the parties involved, and any relevant terms that were agreed upon. Having this clear documentation is essential for maintaining accurate records in the USPTO database and ensuring that the new owner holds the rights to the trademark.

Other choices do not fulfill the requirement properly. For instance, an original statement by the owner would not provide sufficient legal backing to demonstrate the transfer. A disclaimer of prior ownership typically relates to avoiding confusion about rights, rather than documenting a transfer. A notification letter to the trademark office may serve as an alert to the office, but it does not function as the primary document proving ownership transfer. Hence, the specific document indicating the transfer of ownership is vital for the validity of the assignment
