Getting a patent for a cannabis product is no more difficult than getting a patent for any other kind of product. However, with a high number of cannabis patent applications being approved, it is likely that many will be challenged for invalidation in the coming years.
Already one of these patents has gone to court in the U.S. District Court for the District of Colorado. In United Cannabis v. Pure Hemp Collective, United Cannabis Corp. claims that Pure Hemp Collective Inc. used a cannabis extract that United Cannabis had a patent on. Pure Hemp filed a motion for partial summary judgment, arguing United Cannabis should not have had a patent on the extract because it was something that occurred naturally. In April, U.S. District Judge William Martinez found the strain was altered and would not have occurred naturally and denied the motion for partial summary judgment. The case is still pending..

On May 2, 2019, the United States Patent and Trademark Office (USPTO) made available a new examination guide aimed at clarifying the examination procedure for trademarks used in connection with cannabis and cannabis-derived goods and services.
These guidelines are a direct response to the signing of the Agricultural Improvement Act of 2018 (2018 Farm Bill) into law on December 20, 2018. The 2018 Farm Bill changes certain federal authorities relating to the production and marketing of “hemp,” defined as “the plant Cannabis sativa L. and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9 tetrahydrocannabinol [THC] concentration of not more than 0.3 percent on a dry weight basis.” These changes include removing hemp from the Controlled Substance Act’s (CSA) definition of marijuana, which means that cannabis plants and derivatives such as cannabidiol (CBD) that contain no more than 0.3 percent THC are no longer controlled substances under the CSA.

Cannabis patent proceedings are no longer something reserved for a hypothetical future when cannabis becomes legal at the federal level. On January 3, 2019, the Patent Trial and Appeal Board at the United States Patent Office (USPTO) issued its decision in the Inter Partes review, Insys Development Company, Inc. v. GW Pharma Limited and Otsuka Pharmaceutical Co., (IPR 2017-00503). This is the first time that a patent covering a cannabis-related technology has been the subject of an inter partes proceeding at the USPTO. Even though cannabis remains a Schedule I controlled substance under U.S. federal law, the USPTO, a federal agency of the U.S. Department of Commerce, routinely grants patents covering cannabis-related technologies. Because enforcement of patent rights is governed by federal law, the Schedule I status of cannabis has cast uncertainty over whether cannabis patent rights can actually be challenged or enforced. The recent PTAB proceeding shows that they can be challenged.
Inter Partes Review (IPR) is a trial proceeding at the Patent and Trial Appeal Board (PTAB) of the USPTO that permits a third-party to challenge the validity of claims of a granted patent. If the challenger demonstrates that the claimed technology was known to the public before the patent application was filed, then the claims fail to meet the novelty and/or nonobviousness requirements and the Board can declare the patent invalid.
