No cultivar name of record
This patent does not name the plant, which is unusual for its date — by the mid-1990s nearly every plant patent carried a cultivar name. The grant identifies this one by its number and by a written description instead.
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 new and distinct grapevine denominated varietally as F.P.C.D.O.V.#1 generally resembling in some regards the Thompson Seedless grapevine, but characterized as to novelty by producing grapes which are mature for harvesting or for cane cutting for DOV raisin production approximately 2 to 4 weeks ahead of the Thompson Seedless grapevine growing at Fresno, Calif.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described and illustrated my new variety of grapevine, I claim: 1. A new and distinct variety of grapevine to be denominated varietally as F.P.C.D.O.V.#1 substantially as illustrated and described and which is characterized principally as to novelty by its production of seedless berries which are ripe for harvesting or drying-on-the-vine raisin production approximately 2 to 4 weeks ahead of the Thompson Seedless grapevines which ripen at the same geographical location.
