US Plant Patent PP4063
Rose plant
PUBLIC DOMAIN
Patent expired June 21, 1994. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on April 26, 1996, but this patent ends 675 days earlier — a terminal disclaimer gives term back. A source that calculates twenty years from filing would tell you this plant is still protected when it is already free.

No cultivar name of record
This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A tall outdoor bush rose plant of the Grandiflora class, having a vigorous much-branched habit of growth and carrying strong, short to medium length flowering stems, sometimes with one bloom or sometimes with three or more blooms to the stem. Resistance to mildew is significantly better than with plants of the same genus under comparable conditions. The general color effect is between brilliant yellow and moderate orange yellow when the flower is freshly opened. This lightens to generally lighter tones of the same shading after the flower has been open for several days. Blooms have a slight pollen fragrance.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. The new and distinct variety of Grandiflora rose plant substantially as herein illustrated and described, which is characterized by a plurality of the following features, in combination, namely a notably vigorous, upright habit of growth, many-branched and tall, with abundant glossy medium-sized foliage, said plant being more hardy and more resistant to mildew than is usual with plants of the same species grown under comparable conditions; a nearly continuous blooming habit throughout the season; blooms with double petalage which have a predominantly yellow color effect, varying mainly in depth of shade, and having a mild, pollen-like fragrance; many of the flowering stems carrying only a single flower.
