In part 3 of the series, Naiberg tackles plant breeders’ rights and how cannabis breeders in Canada could protect new plant varieties.

Editor’s Note: This is the third 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 and Part 2 went into how business owners can protect new technologies and inventions through applying for patents. Part 3, below, delves into plant breeders’ rights and how breeders in Canada could protect new plant varieties.

Plant Breeders’ Rights: Protection For New Plant Varieties

Unlike the Patent Act, Canada’s Plant Breeders’ Rights Act does provide intellectual property protection for whole plants. Plant breeder’s rights are available for new cannabis plants, whether they are the product of genetic engineering or more traditional cross breeding.

The applicant must also propose a name (referred to as a “denomination”) for the new variety that is acceptable to the Commissioner.The Plant Breeders’ Rights Act focuses on the material used to propagate a new variety of plant, such as its seeds. The owner of a plant breeder’s right can stop others from selling, producing or reproducing the propagating material, conditioning the propagating material for use, exporting or importing the propagating material, repeatedly using the protected variety to commercially produce another variety, and stocking the propagating material for the purpose of doing any of the above acts. The owner can also assert these same rights to stop another’s activities as they relate to another plant variety that is essentially derived from the protected variety. The owner can also recover for the damages it suffers as a result of any infringement. For cannabis plants, the term of a plant breeder’s rights endures for 20 years from the date of its issuance.

To register a plant-breeder’s right, a breeder provides an application to the Commissioner of Plant Breeders’ Rights Office, which is part of Canadian Food Inspection Agency.

To be registrable, the plant variety must be new, meaning that the propagating material has not been sold in Canada more than 1 year prior to the application (or elsewhere more than 4 years prior to the application); it must be distinguishable from all varieties that are known to exist at date of filing of the application; it must be sufficiently homogeneous, meaning that its relevant characteristics are predictable and commercially acceptable; and it must be stable in its essential characteristics over successive generations. Registration under the Plant Breeders’ Rights Act provides plant breeders’ rights in Canada only. However, Canada is a signatory to a treaty (UPOV) that allows an application originally filed in Canada to provide priority for registration in other member countries, and vice versa.The Commissioner also has the power to require the performance of tests on a sample of the propagating material, such as to verify its stated characteristics.

The applicant must also propose a name (referred to as a “denomination”) for the new variety that is acceptable to the Commissioner. The Plant Breeder’s Rights Act puts limits on what may be chosen as the denomination. Among other things, the denomination cannot refer to characteristics the variety does not have, suggest that it is derived from another variety or bred by a particular breeder when this is not case, or comprise laudatory descriptives that could cause confusion. The denomination cannot be used or registered as a trademark and, once accepted by the Commissioner, must be used by all traders when selling the propagating material, even after the expiry of the plant breeder’s right. Indeed, the Plant Breeders’ Rights Act makes it an offence to misuse or misapply the name. The same denomination will be used for the same variety in all UPOV countries.

The application process can involve some back-and-forth with the Commissioner, as well as the opportunity for others to oppose the registration. The Commissioner also has the power to require the performance of tests on a sample of the propagating material, such as to verify its stated characteristics.

A unique feature of a plant breeder’s right is that it can be enforced even before the Commissioner finishes his or her review against infringers who are given notice of the applicant’s application.

As of this writing, there are three registered denominations of cannabis plants under the Plant Breeders’ Rights Act. Chris Griffin has registered “Big C” – cannabis sativa subsp. indica; and MedReleaf Corp. has registered MR2017001 and MR2017002, both being varieties of cannabis sativa. It is expected that further registrations will follow.

There are some important limitations to the plant breeder’s rights. Farmers who harvest the plant variety on their “holdings” are given a privilege: they can store, produce and reproduce (but cannot sell) the variety on such holdings. The Commissioner also has the power to issue compulsory licenses when a protected variety is not available to the public at reasonable rates. Further, the plant breeder’s right is not infringed when the protected variety is used for non-commercial or experimental purpose.


In Part 4 of the series, Naiberg will discuss trademarks and how cannabis businesses should go about protecting their brand identity in Canada. Stay tuned for more!
