Even though cannabis remains a Schedule I controlled substance under U.S. federal law, the United States Patent Office (USPTO), a federal agency of the U.S. Department of Commerce, routinely grants patents covering cannabis-related technologies. The Schedule I classification of cannabis is not relevant to patentability. As with any other invention, to be patentable, a cannabis-related invention must be new, useful, and nonobvious, and teach one of ordinary skill in the art how to make and use the invention. The USPTO has determined that many cannabis-related patent applications have met these requirements. Patents granted to cannabis-related inventions cover an enormous range of technologies, including cannabis plants, growing systems, extracts, methods of making extracts, foodstuffs, veterinary products, and methods of treating various diseases and disorders.
