Note:
If there is any confusion regarding the acceptability of a proposed variety denomination (variety name), applicants are
advised to contact the Plant Breeders' Rights Office (PBRO).
For varieties of species requiring registration under the Seeds Act, there may be additional restrictions or
requirements concerning the variety name. Applicants should consult with the Variety
Registration Office of CFIA's Seed Section for
information.
General Principles
Publication and Approval
Every variety must be identified by a denomination (name) proposed by the applicant and approved by the Commissioner. If
a denomination has not been chosen for a new variety at the time of filing the application for PBR, the application can be filed under an experimental number or proposed
denomination which can be changed any time before rights are granted. The variety denomination shall only be approved by the
Commissioner at the time of grant of rights. Prior to the approval, the proposed denomination of a variety must be published
in the Plant Varieties Journal, and subjected to a six-month objection period. During this time, if there are any
valid objections to the proposed denomination, the applicant will be asked to propose a different denomination for the
variety. Unless limited by provisions under the Seeds Act, reproductive material of a protected variety should be
identified by the approved variety denomination when advertised or offered for sale. No name, other than the approved
denomination, may be used, unless (as in the case of a marketing name) it is used in association with the approved variety
denomination.
One Variety - One Name
If a variety has been protected, or if an application for protection has been filed, in another country, the variety
denomination in Canada must be the same as the denomination in the other country(ies). If the variety is not protected in
another country but is being marketed or is known by a particular denomination in that country, that same denomination must
be used if the variety is protected in Canada. This is in keeping with the "one variety, one name" policy and
reflects the importance of the single denomination for each variety worldwide. In some circumstances it may be necessary to
protect the variety under a different denomination in Canada, for instance, if the variety denomination is found to be
unacceptable here for some reason. In that case, the denomination by which the variety is known and/or protected in other
countries is listed as a synonym. For varieties of crops requiring registration under the Seeds Act, the registered
variety name and the denomination under which Plant Breeders' Rights are granted must be the same.
Trademarks
The use of a variety denomination cannot be restricted by any other designation, such as a trademark, even after the
rights for the variety have expired. Therefore, no denomination nor any part of a denomination approved for PBR can be trademarked in Canada. This is because the holder of the rights must
ensure free use of the variety denomination even after the rights have expired. Since trademark protection can last
indefinitely, it would not be free for use upon expiry of the plant breeders' right.
Marketing Names
For some species, trade or marketing names (which may or may not be trademarked) may be used in association with variety
denominations for the purpose of marketing propagating material, but only if the approved variety denomination is easily
recognizable. For example, the approved denomination of a Petunia variety may be PT123 but the breeder may wish to market
the variety as Snow Flake. In this case, propagating material could be sold as PT123 or as PT123 Snow Flake. However, for
varieties of agricultural crops there are specific labelling requirements under the Seeds Act and the use of
another name in combination with the official variety name may be prohibited. Applicants are advised to consult the Seed Section, CFIA.
Changes to a Variety Denomination
Throughout the application process, the applicant is responsible for notifying the PBR Office of any changes to a proposed variety denomination. Once rights have been
granted to a variety, the denomination may only be changed under very specific circumstances:
- where, by mistake, the denomination approved was not the denomination proposed by the applicant; or
- where additional information becomes available following grant of rights justifying a change of denomination; such as an
existing right of another person to the use of the designation.
Variety Naming Guidelines
A denomination must conform to the guidelines outlined below. These guidelines are based on UPOV naming guidelines.
- The use of genus or species names, common crop names or names of botanical types should be
avoided for varieties within the same crop sectors i.e. agricultural crop sector, ornamental
and forestry crop sector, vegetable crop sector and fruit crop sector. For example, a variety of barley named Rose would be
acceptable however a variety of petunia named Rose would not.
- Denominations liable to mislead and/or cause confusion should be avoided. A denomination should
be avoided that gives the impression that the variety:
- has particular characteristics it does not have; or
- is the only one with that characteristic when in fact others also have it; or
- is derived from, or related to, another variety when this is not the case; or
- has been bred by a certain breeder, when this is not the case.
- Denominations should not cause confusion concerning the value of the variety by the use of
comparatives or superlatives, such as better, best, superior, sweeter, etc.
- The prior rights of third persons shall not be affected by the use of a proposed denomination.
A denomination cannot be accepted if another right, already granted to a third party under any intellectual property
legislation, is already in use.
- A variety denomination must contain a minimum of two characters.
- In general, the difference of a single letter or number between two denominations may be
considered liable to mislead or cause confusion concerning the identity of the variety, except where
- the difference of one letter is prominent in a way that it makes the denomination clearly distinct;
- the denomination consists of a combination of letters and numbers;
- the denomination consists solely of figures. The use of numbers alone is not recommended for naming varieties, unless it
is an established practice where a variety is marketed within a limited circle of specialists (e.g., inbred lines etc.) or is an accepted market practice for
particular variety types (e.g., hybrids etc.).
- Any explicit or implicit claims incorporated as part of a variety name may only be used if they
are accurate and verifiable. For example, in the case of some wheat varieties, the prefixes, for Fusarium Tolerant (FT), or
for Fusarium tolerant high protein (FTHP).
- A variety name shall not be such as to be considered offensive.
- If a variety is protected, marketed or known in another country and the denomination is not
acceptable to the Commissioner, alternate names may be used and will be the proposed denomination. The denomination used in
the foreign country(ies) will be recorded as a synonym.
- Accents or other marks may be included with a French variety denomination. However, the
addition or deletion of such accents does not constitute enough of a difference to be considered a new denomination.
- No punctuation marks or other typographical symbols, subscripts, superscripts or designs are
allowed in any denomination. However, hyphens are acceptable, as are spaces when they are used between words.
- For denominations consisting of only numbers or number/letter combinations, the use of spaces
is strongly discouraged. In addition, and as much as possible, denominations consisting of number/letter combinations should
not contain more than 10 characters.
- Denominations consisting of mixtures of upper and lower case letters (excluding the first
letter of a name) and upper case letters only are discouraged.
- Where a variety is no longer protected, the denomination may not be reused for a variety of the
same or similar crop kind. However, a denomination may be re-used where the original variety is no longer cultivated and the
denomination has not acquired particular importance. These situations are determined on a case-by-case basis but generally,
if the original variety no longer remains in commercial existence, and has not been included on an official list or register
of plant varieties within the last ten years, the denomination may be able to be re-used.
- A denomination should be unique, in that it should not be used more than once in the same
botanical class. The classes have been developed such that the botanical taxa within the same class are considered to be
closely related and/or liable to mislead or to cause confusion concerning the identity of the variety. In most cases a
denomination class is equal to a genus; however there are exceptions forming special classes. The variety denomination
classes can be found in Annex 1 of UPOV document UPOV/INF/12/3 – PDF
