US Plant Patent PP35836

OT-1

Cannabis plant named ‘OT-1’

UNDER PATENT

Still under patent. Protection ends December 11, 2040.

Twenty years from the filing date would end on November 29, 2042, 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.
