Genus

Leptospermum

2 US plant patents have been granted in this genus. 1 is already in the public domain — anyone may propagate and sell it. The next of the 1 still protected comes off patent on May 6, 2040.

Still under patent — 1 cultivar

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

Already in the public domain — 1 cultivar

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

A patent expiring frees the plant, and its cultivar name comes with it — cultivar names cannot be trademarked, so they are always free to use. What it does not free is any brand name the plant is marketed under. Those are trademarks and renew indefinitely.
