Who’s Afraid of Biotech Institute LLC?

While cannabis patenting activity is still in its infancy, relatively speaking, a lot has been written already about the cannabis patenting activity of an entity called Biotech Institute LLC (BI) of Westlake Village, California.1 BI is building a sizable portfolio of utility and plant patents covering various aspects of the cannabis plant. According to some commentators, BI’s patents have “many in the cannabis industry concerned.”2

But how concerned should members of the cannabis industry really be about BI’s patents? Generally, patents are susceptible to numerous challenges in multiple fora. From 2012-2016, approximately 80% of challenged patents were invalidated by the Patent Trial and Appeal Board (PTAB) each year.3 The PTAB was created in 2011 by the Leahy-Smith America Invents Act, 35 U.S.C. § 6, to create a process for eliminating improvidently issued patents. And the statistics suggest that the process may be working as intended by Congress.

BI may be building its portfolio by taking advantage of some unique challenges in the cannabis patenting area. First, even though cannabis has been cultivated and consumed by humans for thousands of years, there is a relative lack of published prior art available to patentees and patent examiners examining patent applications.4 Second, patent examiners are not as familiar with cannabis patent applications as they may be with other types of patent applications.

So, we examined carefully BI’s earliest and arguably broadest utility patent, U.S. Patent No. 9,095,554, and concluded that maybe the cannabis industry need not be so concerned about this and some of BI’s other utility patents. Although the ’554 patent is lengthy – 247 columns of text and over an inch thick when printed in hardcopy – there appears to be little if any novelty to the claimed invention. Alternatively, the patent appears to be obvious in light of the available prior art.

In a patent, the claims define the metes and bounds of the patentee’s intellectual property. Claim 1 of the ’554 patent recites:

  1. A hybrid cannabis plant, or an asexual clone of said hybrid cannabis plant, or a plant part, tissue, or cell thereof, which produces a female inflorescence, said inflorescence comprising:
  1. a BT/BD genotype;
  2. a terpene profile in which myrcene is not the dominant terpene;
  3. a terpene oil content greater than about 1.0% by weight; and
  4. a CBD content greater than 3%;
  5. wherein the terpene profile is defined as terpinolene, alpha phelladrene, beta ocimene, careen, limonene, gamma terpinene, alpha pinene, alpha terpinene, beta pinene, fenchol, camphene, alpha terpineol, alpha humulene, beta caryophyllene, linalool, cary oxide, and myrcene, and wherein the terpene oil content is determined by the additive content of the terpenes in the terpene profile; and wherein the terpene contents and CBD content are measured by gas chromatography-flame ionization detection (GC-FID) and calculated based on dry weight of the inflorescence; wherein a representative sample of seed producing said plants has been deposited under NCIMB Nos. 42246, 42247, 42248, 42249, 42250, and 42254.

While claim elements define the metes and bounds of the invention, typically only certain claim elements are intended to distinguish the claimed invention from the prior art. Other claim elements merely help to describe the invention. For example, the preamble in the ‘554 patent, or the part of the claim before subpart (a), describes the flowering part of the cannabis plant. This is not intended to describe anything novel about the claimed invention, but rather it simply describes the part of the cannabis plant that is relevant to the invention.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

Before the priority date of the ’554 patent, it was known in the prior art that BT/BD genotypes produce nearly equal amounts of THC and CBD (both are dominant; one is not recessive).5 Thus, it is not unexpected to have a CBD content greater than 3% in a genotype that can produce large amounts of CBD (known references state as high as 21% in CBD-dominant strains and 3%-15% in BT/BD genotypes).6 Further, it was known in the prior art that terpenes generally constitute more than 1.0% percent by weight (usually between 2-4%) of the flower.7

As these databases continue to grow and studies of cannabis are publicly disclosed, cannabis patents like BI’s ’554 patent will become more and more susceptible to patent challenges and invalidation.Claim element (b), reciting a terpene profile in which myrcene is not the dominant terpene, appears to be one of – if not the only – claimed element of novelty of the BI invention. Terpenes are aromatic compounds produced in plants, and the cannabis plant has more than 100 different terpenes. Claim element (e) simply lists the most abundant terpenes in the cannabis plant. A majority of cannabis strains express high levels of myrcene; however, there are known prior art strains that express high levels of other terpenes, such as caryophyllene, limonene, pinene, etc. Additionally, it is well known in the art that terpenes have different therapeutic effects. For example, pinene and linalool are known to have antidepressant activity.8 Thus, a prior disclosure of a BT/BD genotype that has a terpene profile where myrcene is not the dominate terpene very likely invalidates this claim. And even assuming there is any novelty to a high-CBD strain where myrcene is not the dominant terpene, there is a motivation to breed for a dominant terpene besides myrcene.

Because cannabis has been and remains a Schedule I drug under the Controlled Substances Act, previously known and used strains generally have not been chemically characterized, studied, researched, and the subject of publications that can be used as prior art for purposes of challenging cannabis patents. But that is changing. For example, the Open Cannabis Project (OCP) attempted to characterize and publish chemical details of cannabis plants. Even though OCP closed as of May 31, 2019, is database is still publicly available. Another example is CANNA, a non-profit initiative of the CANNA Espana Fertilizantes SL company, which carries out studies and conducts research on cannabis and its active compounds.9 In one study,10 CANNA found that some strains have terpene profiles where myrcene is not the dominant terpene, which could be relevant to a novelty-based or obviousness challenge to claim 1 of the ‘554 patent. As these databases continue to grow and studies of cannabis are publicly disclosed, cannabis patents like BI’s ’554 patent will become more and more susceptible to patent challenges and invalidation.

Protecting Intellectual Property in Canada: A Practical Guide, Part 2

Editor’s Note: This is the second article in a series by Richard Naiberg where he discusses how cannabis businesses can protect their intellectual property in Canada. Part 1 introduced the topic and examined the use of trade secrets in business. Part 2 goes into how business owners can protect new technologies and inventions through applying for patents.

Patents: Protection For New And Inventive Technology

Patents, which are issued in accordance with Canada’s Patent Act, provide their owners with the right to have a Court prevent anyone else in Canada from making, using, selling, importing or exporting what is claimed as the patent’s invention. The owner of the patent enjoys this monopoly for a period of 20 years from the date the patent is applied for. A patent is infringed even if the infringer arrives at the invention independently, without actual copying. If a patent owner brings a lawsuit and the Court finds infringement, the Court will typically order the infringing activity to cease and require the infringer to pay the owner a suitable amount of compensation.

There are several drawbacks to applying for a patent from the point of view of the applicant.Patents are meant to protect only inventions, meaning novel, non-obvious and useful solutions to practical problems. In the cannabis field, such inventions could include engineered genetic sequences or new plant cells that lead to useful improvements in the whole plant, new cultivation processes, new methods of extraction, new methods of storage or means to enhance stability, new formulations for administration, and new uses for the plant. It would not be uncommon for a cannabis producer to hold a suite of different patents that cover a whole range of innovative technologies and innovative business methods.

Not all classes of technical innovations are protectable by patent. For example, patents are not available for a whole cannabis plant because no patents are allowed on higher, multicellular organisms. Patents are not issued for genetic sequences or cells that are the result of cross breeding. Patents are also unavailable to monopolize methods of using cannabis as a medical treatment. That said, patent agents are skilled at casting innovations in areas such as these in terms that do provide some patent rights.

To obtain a patent, the applicant hires a patent agent to prepare and submit an application to the Canadian Intellectual Property Office (CIPO). An examiner at CIPO reviews the application for compliance with the statutory requirements and enters into a correspondence with the applicant’s patent agent in a process known as a patent prosecution. Third parties also have the opportunity to oppose the grant of a patent on limited grounds. The prosecution may continue for a period of years before the application is either allowed to issue to patent, or is ultimately rejected. Separate patent applications must be filed in every country in which patent rights are sought, though there are international treaties that facilitate these separate filings and preserve early priority filing dates.there can be a significant cost in obtaining patents, particularly if patent rights are sought in multiple countries.

It is important to emphasize that if an invention had been disclosed to the public more than one year before the application for the patent is filed, a patent cannot issue. Cannabis producers must therefore ensure that disclosures of their innovative work be controlled, including when working with partners. This can typically be handled with the use of appropriate non-disclosure agreements.

The prospect of market exclusivity makes the filing of patent applications a must for cannabis businesses, including those just starting out. For a start-up, simply filing a patent application projects that the company has value and a clear vision of its business. Venture capital often seeks companies with patent applications on file because the applications can mature into assets which can be monetized either by protecting a market for the owner, or through assignment or license to others.

cannabis researchers and producers have already filed hundreds of patent applications in Canada. There are several drawbacks to applying for a patent from the point of view of the applicant. Unlike the case for a trade secret, an applicant for a patent must make full and correct disclosure of the invention and how to use it in the patent itself. This disclosure will allow competitors to understand the applicant’s technology. The public disclosure provides a blueprint for competitors to build upon the patent’s disclosure, and to design around it to avoid infringement. Also, and unlike trade secrets, patents have an expiry date after which the public is free to practice the invention. The Commissioner also has the power to issue compulsory licenses to third parties in several circumstances, including when the demand for the patented article is not being met on reasonable terms. Further, the patent right is not infringed when the patented invention is used for non-commercial or experimental purpose. Finally, there can be a significant cost in obtaining patents, particularly if patent rights are sought in multiple countries.

Disadvantages or not, cannabis researchers and producers have already filed hundreds of patent applications in Canada. These applications relate to a wide range of inventions in the cannabis field including new cannabis resins and oils, methods of producing cannabis having improved properties, specific new growing processes, new harvesting methods, new extraction techniques, new formulations for human and veterinary use as foods, medicines and supplements, new delivery devices, new purification methods, new analytical methods, and new stabilization methods. Interested companies can access these disclosures from the public record.

As cannabis companies rush to obtain patent monopolies for their technologies, minefields are created for operating companies. Cannabis producers should obtain reports on what patent applications exist and might be asserted against their operations if and when these applications mature to issuance. With that intelligence in hand, the cannabis producer can understand what threats can be safely ignored and what patents must be addressed by assignment or license, by ‘design around’ or by developing an argument as to why the patent is invalid and thus unenforceable.

Editor’s Note: In Part 3 of this series, which will be published next week, Naiberg will discuss plant breeders’ rights and protecting new plant varieties. Stay tuned for more!
