US Plant Patent PP4107
Nectarine tree
PUBLIC DOMAIN
Patent expired September 20, 1994. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on July 28, 1996, but this patent ends 677 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.

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 nectarine tree, substantially as illustrated and described, bearing large, yellow flesh, clingstone fruit approximately the same maturity season as Late Le Grand Nectarine (U.S. Plant Pat. No. 1,035), but being an improvement over other nectarines in this maturity season by producing fruit with a higher degree of red skin color. The nectarine tree is further characterized for heavy production, regular bearing of large firm high colored fruit, with long distance shipping quality.
