Plant

Lily

219 US plant patents name this plant. 195 have expired, so those cultivars are free to propagate and sell. The next of the 24 still protected comes off patent on April 21, 2028.

Still under patent — 24 cultivars

Soonest to come off patent first. You may not propagate these for sale until the date shown.

Already in the public domain — 195 cultivars

Most recently freed first. Anyone may propagate and sell these plants — though the name it is sold under may still be a live trademark.

Botanically this is Lilium. A patent expiring frees the plant, and its cultivar name with it — cultivar names cannot be trademarked. Any brand name it is sold under is a separate thing and may still be owned.
