The Plant Variety Protection
Office (PVPO) is charged with providing legal rights in accord
with The Plant Variety Protection Act of 1970 (84 Stat. 1542)(7
U.S.C. 2321 et seq.); plant breeders' rights. These rights of
intellectual property are granted to owners who desire exclusive
privileges regarding the sale, reproduction, import, and export of new
varieties of plants which have met or surpassed certain criteria
relating to distinctness, genetic uniformity, and genetic stability.
The successful applicant is granted a Certificate of Protection for
the application variety which remains in force for 20 years, in return
for which they agree to public disclosure of certain facts, including
the description of the variety and its breeding history. Since the
inception of The Act, The Office has been charged with maintaining a
collection of data which includes descriptions of existing varieties.
These data are used to compare with the application varieties thereby
assessing the novelty, uniformity, and stability of the proposed new
Until 1983, the only data commonly released to the public were copies
of certificates which had been issued for successful applicants. In
1983, the data for soybeans was released but there was little interest
from plant breeders. As personal computers became more commonplace,
the ability to quickly scan or search a database made the PVPO data
more attractive and useful. In late 1989, an administrative directive
provided that non-classified Department of Agriculture data could be
made available to the general public in both printed, and electronic
form. In 1991, the
were again made available, this time on computer diskettes. The public
response was significantly greater than in 1983.
