What is required when filing an assignment of ownership for a trademark?

When filing an assignment of ownership for a trademark, it is essential to provide a legal document that effectively transfers ownership from the assignor (the current owner) to the assignee (the new owner). This legal document is typically referred to as an "assignment agreement" and should clearly outline the details of the transfer, including the parties involved and the trademark in question.

The legal document serves as proof of the change in ownership and must be executed according to legal standards to ensure it is enforceable. It is not sufficient to simply file a new application, make a payment, or provide an affidavit. Instead, the filing must include this formal agreement to properly record the change in ownership with the United States Patent and Trademark Office (USPTO), thereby protecting the rights of the new owner and ensuring the trademark remains valid and enforceable.
