Trademarking Hemp and Cannabis Products

In recent years, the cannabis industry has seen a surge in growth and innovation, with changing laws and attitudes toward marijuana and hemp. As legalization spreads across the United States, businesses in this industry face unique challenges, one of which is protecting their cannabis trademarks. In this comprehensive blog post, we will explore the intricacies of trademarking hemp and cannabis products and services with the United States Patent and Trademark Office (USPTO). Whether you’re a business owner in the cannabis space or simply interested in understanding federal trademark law in this emerging field, this post will provide you with valuable insights.

The Need for Trademark Protection

As the legal landscape surrounding cannabis and hemp continues to evolve, the importance of trademark protection becomes increasingly evident. Trademarks are vital assets for businesses, allowing them to establish brand recognition, protect their intellectual property, and build consumer trust. Trademark registration, particularly with the USPTO, offers several advantages, including nationwide protection, a presumption of validity, and the right to use the ® symbol. However, obtaining federal trademark registration for cannabis-related goods and services presents unique challenges due to the complex legal framework governing this industry.

Understanding Federal vs. State Laws

To grasp the complexities of trademarking hemp and cannabis products, it’s essential to distinguish between federal and state laws. While individual states have legalized various forms of cannabis for medical and recreational use, it remains illegal under federal law. This contradiction creates a challenging environment for businesses seeking federal trademark protection, as the USPTO requires that the use of the mark be federally lawful.

Federal Trademark Registration for Hemp-Derived Products

Certain hemp-derived products containing less than 0.3% THC on a dry-weight basis may be eligible for federal trademark registration. The USPTO evaluates the legality of cannabis-related goods by considering the Controlled Substances Act (CSA), the Federal Food, Drug, and Cosmetic Act (FDCA), and the 2018 Farm Bill. The removal of “hemp” from the CSA’s definition of marijuana by the 2018 Farm Bill has opened the door for potential federal trademark registration for hemp and its derivatives, such as CBD. However, it is essential to stay informed about the evolving legal landscape, as other cannabis products and related services are not yet federally legal.

Federal Trademark Registration for Cannabis-Related Services

Certain services related to the production of hemp-derived products may also be eligible for federal trademark protection if they meet specific criteria outlined in the CSA and the 2018 Farm Bill. The USPTO assesses compliance with these laws when evaluating trademark applications for such services.

Be Prepared for the USPTO To Issue Office Actions

The USPTO may require additional information during the trademark application process. These inquiries can range from questions about the nature of the goods and services to prospective consumers and distribution channels. In some instances, the USPTO may request proof of the THC content on a dry-weight basis. Additionally, if your application involves services that include the cultivation or production of cannabis, the USPTO will likely ask for information regarding your permission to produce hemp under a state, territorial, or tribal government license or authorization. Being prepared to respond to these inquiries is crucial for a smooth trademark registration process.

Restrictions on Certain Cannabis-Related Products

While federal trademark registration may be attainable for some hemp-derived products, it’s important to note that the FDCA places restrictions on certain items, including foods, beverages, dietary supplements, and pet treats containing CBD, even if they contain less than 0.3% THC. These restrictions are rooted in federal regulations governing the sale and transportation of such products in interstate commerce. Therefore, businesses in the cannabis industry should explore alternative strategies to protect trademarks associated with these products.

Diversify Your Trademark Portfolio

A strategic approach to trademark protection involves diversifying your trademark portfolio. If your business produces both ingestible and non-ingestible products with less than 0.3% Delta-9 THC on a dry-weight basis, consider seeking federal trademark registration for your non-ingestible products. This approach can establish your brand’s presence in the market and pave the way for potential registrations for ingestible products once they become federally legal. It’s a proactive strategy that positions your business for success in a shifting regulatory landscape.

State Trademark Registration and Common Law Rights

In addition to federal options, state trademark registration and the establishment of common law rights offer alternative paths to protect trademarks for cannabis-related goods and services. Some states that have legalized marijuana offer state trademark registrations, which can provide valuable protection within those specific jurisdictions. The requirements and processes for state trademark registrations may vary, but generally, applicants must file their applications with the state’s secretary of state or a similar governing entity. Maintenance requirements, typically occurring every five to ten years, depend on the state.

Moreover, the use of your trademark in commerce establishes common law rights in the trademark within the geographic areas where it is employed for commercial purposes. These common law rights can serve as a valuable layer of protection, especially in the absence of federal registration.

Don’t Wait for Federal Changes

The regulatory landscape surrounding cannabis remains in flux, and the potential rescheduling of marijuana as a Schedule III drug is a topic of ongoing discussion. However, businesses should not delay taking action to protect their trademark rights. Pursuing federal trademark registrations for products and services containing less than 0.3% Delta-9 THC on a dry-weight basis that are not ingestible remains a viable strategy. Additionally, considering state trademark registrations in states where cannabis is legal can be a proactive step. Waiting may allow competitors to secure state registrations that could pose challenges to your future federal registration efforts if marijuana is no longer classified as a Schedule III drug.

Bonus Tip: Strategic Cannabis Trademark Planning

Even if your cannabis product or service does not meet the criteria for federal trademark registration, a strategic approach to trademarks can still provide valuable protection. Key elements of this approach include selecting a distinctive and strong trademark, conducting comprehensive clearance searches to avoid conflicts with existing marks, and exploring state trademark registration options. Furthermore, if your business offers ancillary goods or services related to marijuana, such as informational websites, apparel, or smoking paraphernalia, federal trademark registration may be available for these legal items. This can help prevent subsequent registrations of similar trademarks and provide the advantages and presumptions afforded to federal trademark owners.

International Trademark Law For Hemp or Cannabis Derived Products

International trademark protection operates under the framework of international treaties and agreements, such as the Madrid Protocol and the Paris Convention. These agreements provide mechanisms for trademark owners to seek protection in multiple countries through a single application, streamlining the process for businesses seeking to establish a global presence.

For businesses operating in the cannabis industry, international trademark laws can have both opportunities and challenges. Trademark protection granted in one country does not automatically extend to all nations, necessitating a thoughtful and strategic approach to international trademark registration. Factors such as the legal status of cannabis in the target country, potential conflicts with existing trademarks, and the specific goods and services offered must all be considered.

Furthermore, businesses considering international expansion must navigate the varying legal landscapes of cannabis-related regulations in each jurisdiction. Some countries have embraced cannabis legalization, while others maintain strict prohibitions. This divergence in legal status can impact the feasibility of trademark registration and enforceability in specific regions. However, for businesses operating in countries with legalized cannabis markets and those planning to enter such markets, international trademark protection can be a valuable asset. It can help establish brand recognition, protect intellectual property, and foster consumer trust on a global scale.


Trademarking hemp and cannabis products and services with the USPTO is a multifaceted process that demands a thorough understanding of federal and state laws, as well as strategic planning. The evolving legal landscape adds an additional layer of complexity, making it essential for businesses in this industry to be proactive in protecting their trademarks. By following the tips and strategies outlined in this comprehensive guide, you can navigate the challenges and seize opportunities in the dynamic world of cannabis and hemp trademark protection. Your trademarks are invaluable assets, and safeguarding them is a critical step toward long-term success in this burgeoning industry.
