In response to the changes made in the 2018 Farm Bill, the USPTO released a guidance document on May 2, 2019, regarding trademarks for CBD goods or hemp-derived products. Examiners will check for compliance of the goods based on the 2018 Farm bill. But the legality for food or dietary supplements under the FDA is still in question. The PTO examiner will also require evidence of a license or authorization by a state, territory, or tribal government. Many lawful, hemp-based producers have been running into prosecution issues with registering their marks at the USPTO. Some of these issues can be reduced by providing the right information with the initial application. Complete guidance can be found here.
