US Plant Patent PP4006
Rose plant
PUBLIC DOMAIN
Patent expired January 4, 1994. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on March 22, 1996, but this patent ends 808 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
1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of an extremely vigorous habit of growth which promotes repeat blooming cycles; constancy of bloom throughout the year; a carnation-like full flower form; and a distinctive and attractive flower color of many shadings, ranging from an almost pure pale yellow color, at times, to a definite "freckled" effect at other times.
