What is required to file a release of security interest with the USPTO?

To successfully file a release of security interest with the USPTO, it is necessary to submit a cover sheet along with supporting legal documentation and a filing fee. The cover sheet serves as a formal request that identifies the nature of the document being submitted, while the supporting legal documentation provides evidence of the actual release of the security interest. The filing fee is required to process the submission. This process ensures that all relevant parties are notified of the change in ownership rights regarding the trademark, maintaining accurate and up-to-date public records.

The other options do not align with the requirements set forth by the USPTO. For instance, a simple written request with proof of ownership may not be sufficient, as it does not include the necessary legal documentation or filing fee. Similarly, submitting an application for trademark registration is unrelated to filing a release of security interest. Lastly, relying solely on verbal confirmation would not fulfill the formal requirements of registering such a legal change, as it lacks the requisite documentation and official processing.
