Important distinction

Plant breeders' rights: Expired: propagation is allowed without a license.
Admission to trade: This is a different legal framework. A variety with expired rights may still be removed from the national catalogue, in which case seed sales are prohibited. Check both statuses on the variety page.

The status is calculated based on dates from official bulletins and does not replace an official register extract. About sources
