The Tennessee Report on Filing Patent/Trademark (AO-120) is a document issued by the Tennessee Secretary of State’s office in response to a request for a search of the records of the Tennessee State Library and Archives. This report is used to determine the availability of a particular patent or trademark in the state of Tennessee. The report includes a brief description of the patent or trademark, the filing date, and the current status of the application. There are two types of Tennessee Report on Filing Patent/Trademark (AO-120): (1) the AO-120-A, which includes an initial search of the records of the Tennessee State Library and Archives; and (2) the AO-120-B, which includes a subsequent search of the same records. Both types of reports provide information on the availability of a particular patent or trademark in the state of Tennessee.
