Introduction

Over the past two decades, cannabis has seen increasing public approval, reflected in legalization of medical and recreational marijuana at the state level and federal legalization of industrial hemp. As cannabis and related industries expand, participants are expected to seek competitive advantages, including patent protection. This report examines trends in United States patent filings and issuances related to cannabis since 2000.

While cannabis legalization has been slowly occurring since the 1990s, a significant development was the legalization of recreational marijuana in Colorado and Washington in 2012. Since then, several other states have followed in opening up recreational markets. Therefore, particular attention is given to activity since 2012, as the existence of recreational markets presumably creates greater competition and greater desire to obtain intellectual property protection. This date also conveniently overlaps with the beginning of implementation of the America Invents Act (AIA), which significantly altered the United States patent system. While changes in patent practice post-AIA are beyond the scope of this report, it is useful to examine behavior year over year from 2012 onward to see if legalization has resulting in increased patent activity.

Summary of Findings

Patent activity related to cannabis has increased significantly over the last decade. Filings of cannabis-related patent applications increased 96% between 2012 and 2019, with filings related to recreational and medical cannabis increasing 257% over the same time. The data show that legalization had a demonstrable effect on cannabis patent activity, and that significant resources are being invested in patent protection in the personal use sector of the cannabis industry. These trends are expected to continue, and industry participants should consider this when making decisions regarding business models and intellectual property protections.

Methodology

Research was performed using the LexisNexis Total Patent One database. Results were limited to United States Patent and Trademark Office (USPTO) publications. The following search terms were used:

  • cannab* – use of the wildcard * returns results for cannabis, cannabinoid, and other variants
  • mari?uana – use of the wildcard ? returns results for marijuana and marihuana
  • tetrahydrocannabinol
  • hemp

The listed terms were searched in the title, abstract, or claims of issued patents and printed publications. Searches were limited by time periods as shown in the detailed results. A complete list of all returned documents was created. Because of the structure of the data, a patent could create multiple documents: an issued patent and one or more published applications. For year-over-year results, these duplicates were not removed. This is not considered significant, as publication of an application and issuance generally occur in different years so double counting is minimal. However, duplicates were removed in calculating the number of filings each year to avoid inflation of filing numbers.

Detailed Findings

Overall Cannabis Patent Trends

Cannabis patent activity has increased notably since 2012. Between 2000 and the end of 2011, the USPTO published 3876 documents concerning cannabis inventions. This number consisted of 2865 published applications and 1011 issued patents. Between 2012 and the end of 2019, the USPTO published 5853 documents, consisting of 3980 published applications and 1873 issued patents. This represents 51% more total documents in 2012-2019 compared with 2000-2011. Publications increased year-over-year since 2012, with a 138% increase between 2012 and 2019.  The charts below demonstrate this trend.

Because patent applications are generally not published until the earlier of issuance or 18 months following filing, publication trends are presumably delayed from filing trends. Therefore, it is useful to examine filing trends since 2012. Because of the 18-month delay prior to publication, data for any filings after July 1, 2018 are incomplete as such applications may not have been published. Therefore, both actual values from 2012 through 2018 and projected values for the years 2018 and 2019 are provided below. Using actual filings from 2017, there has been a 75% increase in filing activity since 2012. Using the projected filings for 2019, there has been a 96% increase in filing activity since 2012. The following charts demonstrate the increase in filing of cannabis-related patents since 2012 based on application filing date information.

The AIA transitioned the United State patent system into a first inventor to file system, which is expected to encourage the early filing of provisional applications to secure priority rights. Provisional applications are not published and therefore do not contribute to the publication or filing data above. However, provisional filing activity can be inferred by looking at the claimed priority dates for published applications and issued patents. While the AIA did not fully take effect until March 2013, data are presented since 2012 for ease of comparison with other metrics in this report. Due to incomplete data for 2018 and 2019 as noted above, both actual and projected values are provided. Using actual priority claims for 2017, there has been a 58% increase in provisional filing activity since 2012. Using projected priority claims for 2019, there has been an 80% increase in provisional filing activity since 2012. The following charts demonstrate filing trends based on claimed priority date of the application.

Hemp as a Distinguishing Factor

Hemp has generally enjoyed more acceptance for its industrial uses than marijuana, despite the fact that both constitute cannabis. Inclusion of hemp is necessary to return all results for cannabis related patents. However, to provide a better picture of post-2012 activity in the recreational market, a separate set of searches was performed omitting “hemp” as a search term. It is presumed that doing so will return patents and applications that are more focused on the recreational or medicinal cannabis market. This is based on the fact that many of the results obtained through searching “hemp” include inventions with industrial applications, such as plant fiber composites or textiles, rather than inventions related to personal use of cannabis. For convenience, such patents are referred to as “recreational.” Because this method of discriminating does not perfectly correlate with the subject of any given patent, the results pertaining to the recreational market represent general trends rather than exact activity. Nonetheless, the trends are worth noting for an evolving industry.

“Recreational” Patent Trends

Between 2000 and the end of 2011, the USPTO published 2115 documents associated with recreational cannabis inventions. This number consisted of 1623 published applications and 492 issued patents. Between 2012 and the end of 2019, the USPTO published 3427 documents associated with recreational cannabis inventions, consisting of 2373 published applications and 1054 issued patents. This represents 62% more total documents in 2012-2019 compared with 2000-2011. Total publications increased year-over-year since 2012, with a 253% increase between 2012 and 2019. Published applications saw an increase of 275% over that period, with issued patents seeing a 209% increase. The charts below demonstrate this trend.

Cannabis Patents Trends legalization of medical and recreational marijuana

These findings correspond to the overall increase in cannabis-related patents and demonstrate that the recreational patent sector is growing at an even greater rate than cannabis patents generally. This supports the theory that recreational markets and expansion of legal personal use of cannabis have resulted in an increase in patent activity in the industry.

Again, publication totals are not necessarily the most accurate reflection of patent behavior by cannabis businesses. Therefore, it is useful to examine filing and provisional trends for recreational patents. These results are subject to the same 18-month delay problems noted above, and therefore actual and projected values are provided. Using actual filing data for 2017, there has been a 181% increase in filing activity since 2012. Using projected filing data for 2019, there has been a 257% increase in recreational filing activity since 2012. Using actual priority claims for 2017, there has been a 196% increase in provisional filing activity since 2012. Using projected priority claims for 2019, there has been a 289% increase in recreational provisional filing activity since 2012. The following charts demonstrate recreational filing trends from 2012 to 2019.

Patents that could be classified as recreational made up approximately 53% of all filings between 2000 and 2011. However, following legalization the percent of patents and applications considered recreational has increased to approximately 77% of filings in 2018. The chart below demonstrates the growth of the recreational sector’s share of cannabis patent activity.

Conclusion

In conclusion, the data provide clear evidence that cannabis patent activity has increased over the last decade. Further, patents associated with the recreational and medicinal sectors of the cannabis industry appear to be increasing at an even greater rate.

Further Developments to Watch

The trends demonstrated in the data suggest that cannabis patent activity will continue to increase in 2020 and beyond. This is further expected due to continued legalization efforts. It remains to be seen whether the federal legalization of industrial hemp and implementation of USDA plans will result in the recreational sector’s share of patent activity decreasing, as activity becomes focused on industrial hemp related patents.

An additional area that merits investigation is the issuance rate of cannabis patents. A rudimentary estimate comparing the number of filings to the number of issued patents for 2012-2019 yields an issue rate of approximately 49.6%. Assuming an average time to issuance of 2.5 years, comparing the total filings from 2012-2017 with the total issued patents from 2012-2019 yields an issue rate of approximately 64%. Comparing the total filings from 2012-2017 with the total issued patents from 2014-2019 yields an issue rate of approximately 52%. The issue rates for recreational patents over the same timeframes are similar. However, given the wide variance in time between filing and issuance, the above rates are only speculative. There has been concern that cannabis patents are issued at a higher rate due to the lack of prior art in the field which examiners can cite against the issuance of a patent. The issuance rates noted above do not seem to lend much support to this concern, as the USPTO claims its overall issuance rate is roughly 68%.

Other concerns have been raised about the strength and usefulness of cannabis patents. It is currently unclear how many issued patents are strong enough to survive challenges of invalidity in either post-grant USPTO proceedings or litigation. Currently, only one major cannabis patent is in litigation.[1] As of this writing, the court appears to be treating the case as any other patent infringement suit.[2] However, industry participants will surely watch the case and its outcome may affect the perceived value of cannabis patents and subsequently alter patent activity.

“UPOV PBR” in the US is Only Available for Industrial Hemp

There are a lot of people out there with some background in plant-related IP and some of them have strong opinions about the right way to do things.  I know because I hear from them.  That’s a wonderful thing about the open lines of communication available via social media and other tools—it seems nearly everyone is accessible to nearly everyone else.  I wouldn’t want it any other way, because this helps me understand what still needs to be emphasized and reinforced in blogs like this.

I’m going to borrow from some interactions this past week or so, editing very lightly to make it more generally useful.  Here is a question I was asked very recently: “If you have 20 years of experience with UPOV PBR why suggest to average clients to get an expensive plant patent for a Cannabis variety? Most can neither afford to obtain or defend a Cannabis plant patent unless I am mistaken?”

And here is my answer:

UPOV in the US is Uniquely Unlike the Rest of the World

First, UPOV Plant Breeders’ Rights in the US are only available under the USDA Plant Variety Protection Act (PVPA) and only cover seed-propagated plants.  An amendment to the PVPA permitting the USDA PVP system to also cover asexually propagated plants was passed as part of the 2018 Farm Bill, but the USDA is still working out the administrative rules and procedures for this, so applications to cover asexually-propagated plants are still not being accepted.

The original limitation in the PVPA to cover only seed-propagated plants was a special carve-out from the normal UPOV scope that covers both sexually and asexually propagated plants, and it was done this way in the US because asexually propagated plants have been covered under the Plant Patent Act since the 1930s (this Act established the plant-patent system as a special form of protection outside of the normal utility-patent system).

A Special Exception in UPOV Just for the US

The US is unique in having this divided IP system, and the UPOV Act of 1991 was specifically written to accommodate this, by including Article 35(2).  If you look at footnote 8 of the list of UPOV members, that “reservation” was exercised by the US and never has been by any other UPOV member.  Since the US is the only country with a split system, no other country will ever need to invoke Article 35(2).

OK so IP to cover plants in the US, unlike anywhere else in the world, is really three different systems:

  1. USDA PVP (i.e., UPOV) which is still available only for sexually propagated plants (but that exclusion will go away soon).
  2. USPTO plant patenting, which is only available for asexually propagated plants.
  3. USPTO utility patenting, which is available for both modes of propagation.

Testing for Distinctness, Uniformity, and Stability

Something else that is very important to know about the USDA PVP system is that it requires a seed deposit with the authorized USDA seed depository.  And until very recently, no kind of Cannabis seeds were accepted for deposit.  Very recently the USDA started accepting deposits of seeds for “Industrial Hemp” as defined in the Farm Bill (Cannabis sativa having less than 0.3% THC).  Once the USDA is equipped to work with asexually propagated plants, it will require “witness plants” for DUS examination.  DUS testing is the UPOV approach to determining whether a given cultivar is suitable for protection.  The D stands for Distinctness and asks whether the cultivar can be distinguished from the closest know cultivars including but not necessarily limited to the parents.  The U is for Uniformity and asks whether a group of seeds or a group of clones all grow out to being true-to-type—having the characteristics that define the cultivar.  The S comes from Stability and asks whether multiple generations of seeds or clones consistently show the same characteristics as previous generations.  These tests are done under consistent conditions to try to remove the variability that would come from different cultivation techniques from one test to the next.

USDA will never accept deposits or witness plants for a form of Cannabis that is still federally illegal.  And USDA has not yet worked out exactly how they will do DUS testing for clones of Industrial Hemp or any other clonally propagated variety people may wish to protect under USDA PVP/UPOV.

What this means, and it is part of my answer to your question about why I would suggest that people get a plant patent for their Cannabis cultivars is that UPOV protection in the US (the USDA PVP system) is that quite literally not available for most Cannabis cultivars that people want to protect.  The only kinds of Cannabis cultivars protectable via UPOV in the US are cultivars of seed-propagated industrial hemp.

If You Want to Protect Marijuana, You Can’t Go to the USDA

I have clients who want to protect their higher-THC cultivars and even who want to protect hemp cultivars that they are cloning instead of seed-propagating.  If I tried to push them toward UPOV protection in the US, I would be committing malpractice because that form of protection is absolutely not available, period.

The “deposit problem” that makes USDA PVP impossible for everything except industrial hemp is not a problem for plant patents, because the plant patent system does not require a deposit of any kind.  So, there’s no issue of federal illegality–the USPTO has been issuing Cannabis-related patents since the 1940s and has so far issued three plant patents for Cannabis cultivars, with many, many more that are pending and working their way through the process.

Getting Real About the Cost Comparison

Another part of your question also deserves comment, and that is the part about plant patents being expensive.  In fact, a USDA PVP application, including the seed deposit, costs $5150 in USDA fees alone.  So even before paying ANY attorney fees for this, the USDA fees by themselves cost more than we charge for preparing and filing a plant patent application.

Obviously there are USPTO fees on top of what we charge for our work doing plant patent applications, and there are costs associated with responding to the very common requests from the USPTO examiner to provide more information about the cultivar, but we typically see cost averages for plant patents, start-to-finish, including USPTO fees, between $10k and $12k paid out over the course of the process from examination to issuance.  I’m not meaning to imply that this is a trivial amount, but it’s very comparable to the cost of obtaining a USDA PVP registration (if it were even available).  ($5150 plus attorney fees for preparing the application and moving it through the process to allowance would likely add up to a total of $8-10k, and potentially more depending upon an attorney’s billing rate and whether anything unusual arose during the DUS testing that would require attorney work to resolve.)

The expensive form of US IP protection for plants is a utility patent.  However, it is currently the only option available for seed-propagated non-hemp Cannabis.  I won’t go into a lot of utility patents because this email is already getting long.  I have blogged about all of this at PlantLaw.com.

I Don’t Tell People What to Do, I Listen and then Tell Them About Their Actual Options

One last part of your question I’d like to address is the part about suggesting to average clients that they get a plant patent.  In fact, I don’t.  I listen first to what they want to accomplish with their cultivar, how they propagate it, how they are going to commercialize it, why they believe that they need some protection, etc.  Then we talk about the options and what their choices are.  It’s a matter of giving good legal advice that takes into account a client’s situation.  And in some cases, the advice is that if their security is strong enough, maybe they don’t need any formal kind of IP protection, especially if they are having trouble affording it.  See this recent blog post, and please do read all of it before deciding it’s incorrect or it’s bad advice.

OK, I hope that explains why I don’t recommend UPOV for my Cannabis clients.  I absolutely would outside the US, obviously, and will within the US, as one option, once the USDA PVP system accepts such applications.  However, even then, there are numerous considerations that go into deciding the right way to protect a given cultivar.  I went into this in a recent blog.

Are Self-Taught Cannabis Breeders Unqualified? I Say No

Just one other comment about plant breeders, and we may just need to agree to disagree on this point.  I have worked with PhD plant breeders at universities and with BS- or MS-level plant breeders who work for several of my clients.  While they have training in genetics and inheritance, every one of them that I have worked with has been focused on phenotypes.  They do a cross of parents that have some of the traits they are looking for and then they grow out many, many of the offspring and select the ones with the best phenotypes and keep propagating and selecting until they have something worth protecting.

This is exactly what I see self-taught Cannabis breeders also doing.  While I may understand more about genetics, epigenetics, pleiotropic inheritance, recombination rates, the biochemistry of terpenes and cannabinoids and flavonoids, these breeders know what they are doing, and they get very special results.  Obviously, some (including some clients I’m working with) are looking for a particular chemotypic profile or at least for something that meets certain chemotypic criteria.  They get their certificates of analysis (COAs), which are now readily available since many states require them as part of the legal Cannabis market.  And the breeders I work with definitely know how to read a COA and make decisions based on it.  College and formal training is not without value, but from where I sit, having worked with breeders whose training ranges from self-taught to PhDs in plant breeding, it seems to me that they end up doing and looking for the same kinds of things.  Now, if one were doing marker-assisted breeding as many in Big Ag do, that would be different.  I’m talking about fruit and grass and flower breeders, whose work approach in general terms is very similar to that of Cannabis breeders I know.

Well, that blog kind of wrote itself this week, by being lifted straight out of an email I sent.  I hope it’s helpful.  You can always get in touch for help with these things by going to PlantAndPlanet.com.

 

HOW’S THAT FOR A TITLE? YOU’D BETTER READ ON

Hubbub Is a Word and It Happened This Week

I always get the best blog ideas from questions that come up during the week, and this week was no exception.  A friend of mine whom I haven’t yet met in person (interesting times, these) brought to my attention some controversy on social media about a plant patent and asked me a series of great questions about the patent itself and the hubbub around it.  (I’m surprised my spellcheck didn’t go nuts just now, but apparently hubbub is a word.)

The crux of it was this:  There was a plant patent posted somewhere on social media and certain portions of the description were highlighted.  One portion described that the new cultivar was made from an open cross between two traditional varieties.  Another highlighted portion pointed to some phenotypic features of this new variety that could apply broadly to a huge number of other varieties as well.

When you look at a plant patent, you’ll typically see several pages of detailed botanical description like “Stem morphology.—Rugose — longitudinal ribs with corky lenticels on older portions.”  Or you might see curious botanical terminology like “hirsute peduncle.”  And, after you google “hirsute peduncle” to see if that’s even real (it is) and what it looks like (it’s not as weird as it sounds), you will still be left wondering how it helps protect this particular cultivar or distinguish it from others.

WHAT TO DO IF YOU DON’T WANT TO BECOME BIG AG’S EDIBLE

Big Ag Will Have You Conform or Go Under

I wrote last week about how Big Ag combines its patent strategies with commodity-market pressures to force farmers to stop growing their own plants and start growing Big Ag’s patented GMO plants or eventually go out of business.  While Big Ag can’t directly make you stop growing your own plants, they can make it impossible for you to compete with the farmers who embrace their system of patented seeds and related Big-Ag products to produce maximum-efficiency yields.  The whole program is designed to drive you out of business if you don’t go along.  And it will do exactly that.

If that sounds crazy or impossible, click over and read that blog.  It’s scary stuff, but it has happened in the soy and corn industries, and Cannabis* is next if we don’t learn the lessons that history stands ready to teach us.  Go ahead and read it; I’ll wait.

(*When I refer to Cannabis in this article and in most places I do so as plant geneticist, which is why I almost always use the capital C.  I’m referring to the genus Cannabis, which ignores distinctions between “hemp” and “marijuana.”  I care about the Cannabis industry and Cannabis breeders, growers, workers, and businesspeople whether they are on the high-THC or the low-THC side.  Here’s hoping that distinction goes away.  And, frankly, our brothers and sisters working in “industrial hemp” need the most help standing up to Big Ag because they will be on the front lines of the coming commodity wars.)

COMMON BUT VERY AVOIDABLE MISTAKES IN PLANT PATENTING

Protect Those Cultivars, But Do It Right

Plant breeders must devote many years and tremendous effort to develop a new plant variety with strong commercial potential.  In order to protect all that effort from illicit copying (propagating), many choose to seek protection under the U.S. plant patent system.  There are some common mistakes that many breeders (and attorneys) make when they are first learning how the plant patent system works.  The three most common are (1) naming the variety in a way that is incompatible with trademark protection; (2) misunderstanding the flexibility of filing-date and disclosure requirements; (3) incorrectly timing the filing of the application.

Don’t Mess Up Your Trademark Rights

When a plant breeder has spent years, or even a decade, developing a new plant variety and has finally made selections and propagation and gone through all the steps to really confirm that a variety has great commercial potential, it is not uncommon to be thinking almost entirely in commercial terms and to have a favorite “sexy name” for their new and exciting variety. The problem is that the sexy name is going to function as intended — in the capacity of a trademark associated with that variety. Trademarks are great, but the plant breeder also must select a “generic name” for the variety. And the tricky part is that the generic name is, by definition, a name that can be universally used in reference to the variety, without infringing anyone’s trademark rights.

Therefore, it is actually necessary for each commercial variety to have TWO names —
