  • Patent Counts by Year

    I searched the USPTO patent database for all patents for which the patent abstract contained any of the following terms: cannabis, cannabinoid, marijuana, tetrahydrocannabinoid, or cannabinol. My search yielded 914 patents.

    As seen in Figure 1, there were only a handful of cannabis patents each year until the late 1990s. Cannabis patent activity started increasing at a roughly constant annual rate between 2001 and 2010. Patent activity leveled off between 2010 and 2015, then accelerated through to the present.
