US Plant Patent PP1
The New Dawn
Climbing or trailing rose
PUBLIC DOMAIN
Patent expired August 18, 1948. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on August 6, 1950, but this patent ends 718 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.
