In our previous post, we touched on some of the interesting issues related to the enforcement of cannabis patents through litigation. In this post, we turn to an alternative to litigation to discuss some of the unique cannabis-related issues that could arise before the Patent Trial and Appeal Board (“PTAB”) of the United States Patent and Trademark Office (“USPTO”).

Trademark practitioners, hemp producers, and hemp-derived product manufacturers have long struggled with the clash of federal and state law regarding protection of trademarks with the United States Patent and Trademark Office (USPTO). Historically, the USPTO has refused registration of marks that include cannabis, hemp, CBD or derived products on the basis that these marks were unable to have lawful use in commerce under existing federal law. These waters became even murkier after the passage of the Agricultural Improvement Act of 2018 (known as the 2018 Farm Bill), which removed “hemp” from the list of controlled substances under the Controlled Substances Act (CSA). On May 2, 2019, the USPTO issued Examination Guide 1-19, outlining the USPTO’s policies with respect to trademarks including legal CBD and hemp-derived goods and services since passage of the 2018 Farm Bill. This appears to open the door for registration of marks that include legal CBD, hemp or hemp-derived products (such as hemp oil), or services such as the cultivation or production of hemp.
