UNDER PATENT

Still under patent. Protection ends June 19, 2030.

Twenty years from the filing date would end on October 15, 2033, but this patent ends 1,214 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.
