PUBLIC DOMAIN
Patent expired November 29, 1994. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on January 24, 1997, but this patent ends 787 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 novel miniature rose variety characterized by its coral pink to light red blossoms.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
The following is claimed: 1. A new and distinct variety of miniature rose plant of hardy, dwarf, bushy, upright, much branched habit, essentially as illustrated and described, characterized by buds and flowers of a coral pink to light red color resembling the Persian Princess miniature rose (U.S. Plant Pat. No. 3,181) but often being somewhat more pink in the bud and opening stages, then becoming more red in the maturing and final stages (especially when grown outdoors), the form and size of bud and flower also being similar to Persian Princess; and further characterized by a plant which is vigorous and relatively compact, said plant being easy to propagate from cuttings, with small, disease resistant, glossy foliage, an abundance of bloom with excellent keeping quality, with flowers borne singly or several to the stem in loose clusters.
