US Plant Patent PP4079

Dwarf nectarine tree

PUBLIC DOMAIN

Patent expired July 19, 1994. This plant is in the public domain — anyone may propagate and sell it.

Twenty years from the filing date would end on August 25, 1996, but this patent ends 768 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 genetically dwarf nectarine tree, with short internodes, which is comparatively large, vigorous, upright, spreading, dense, foliated with large, lanceolate leaves having a glandular, crenate margin, blooms with large, pink flowers, and a regular and very productive bearer of large, uniform, symmetrical, globose, clingstone fruit having yellow skin substantially overspread with red, and yellow flesh.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

I claim: 1. A new and distinct variety of genetically dwarf nectarine tree, substantially as illustrated and described, which has short internodes, is comparatively large, vigorous, upright, spreading, dense, foliated with large, lanceolate leaves having a glandular, crenate margin, blooms with large, pink flowers, and a regular and very productive bearer of large, uniform, symmetrical, globose, clingstone fruit having yellow skin substantially overspread with red, and yellow flesh; the tree, because of such short internodes, being only about 30 percent as high as the Red Grand nectarine, although the fruit, in size and appearance, resembles that of the latter but with much less red around the pit.
