The
Plant Breeders’ Rights Act – Fundamentals
Plant breeders’
rights are an internationally sanctioned form of intellectual
property. The UPOV Convention agreement1
was designed to overcome
two perceived hurdles to the granting of patents for plant
varieties. First, traditional plant-breeding methods (e.g.,
absent the application recombinant DNA technologies) were
thought to lack an inventive step. Second, traditional plant
breeders could not satisfy disclosure requirements of patent
statutes, which required inventors to describe their inventions
sufficiently to enable a person skilled in the art of the
invention to reproduce it. In addition to specifying certain
"plant breeders’ rights," the UPOV Convention
agreement requires signatory nations to provide: (i) national
treatment (foreigners being accorded the same rights under
relevant domestic legislation as nationals); (ii) right of
foreign priority (recognition of foreign priority based on the
filing date of a first application within a member nation); and
(iii) independent jurisdiction (a scheme for acquisition of
rights in a signatory country by application in that country).
Canada signed the UPOV Convention agreement in 1978, but did not
accede to its terms until 1991, when a federal statute, the Plant
Breeders’ Rights Act, came into force.
The Act is
intended to encourage plant breeding in Canada, provide Canadian
producers with improved access to foreign varieties, and
facilitate protection of Canadian-bred varieties in other
countries. It provides a scheme for registering new varieties of
stipulated categories of plants, and grants to registrants, for
a term of 18 years from the date of registration, exclusive
rights to:
- sell and produce in Canada for
the purpose of selling, propagating material (e.g., seed,
whole plants, and vegetative propagating material) as such
(i.e., for the purpose of propagating);
- repeatedly use propagating
material of the variety to commercially produce another
variety, if such repeated use is required for that purpose;
- where the new variety is a
plant variety to which ornamental plants or parts thereof
normally marketed for purposes other than propagation
belong, use any such plants or part commercially as
propagating material for the production of ornamental plants
or cut flowers; and
- authorize such acts
conditionally or unconditionally.
Under the Act, a new
variety eligible for registration must been be homogeneous and
must stably express, during repeated reproduction or
propagation, at least one identifiable characteristic that
clearly distinguishes it from all other varieties known at the
date of application. Furthermore, to be eligible for
registration, neither the breeder nor his, her, or its legal
representative must have sold or concurred in the sale of the
new variety before the date of the application.
Notably and
deliberately (pursuant to the UPOV Convention), the above-stated
rights of registrants contain two important limitations that
distinguish plant breeders’ rights from the rights accorded a
patent holder. These are commonly called the "farmers’
exception" and the "breeders’ exception." By
limiting the sole right of a registrant to selling and producing
in Canada propagating material for the purpose of propagating,
farmers are thereby not restrained from producing in Canada
propagating material for other purposes (e.g., feeding,
processing, or reseeding). By limiting the sole right of a
registrant to repeatedly using propagating material to produce
another variety, if such repeated use is required for that
purpose, other plant breeders are not restrained from
incorporating traits of the protected variety in new varieties
through single crosses.
The scheme is administered by the
Plant Breeders’ Rights Office under the direction of the
Commissioner of that Office. The Plant Breeders’ Rights Office
forms part of the Canadian Food Inspection Agency.
