PUBLIC DOMAIN
Patent expired November 4, 1997. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on March 22, 1999, but this patent ends 503 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. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. 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.

I claim: 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 inside petals of a dark red shade of peculiar brightness and life, with reverse of the petals yellowish cream producing a bicolor effect, with long, tapered formal buds, upright, tall plant habit, and waxy shiny foliage with generally better growth than the parents.
