However, the system of plant patents is based on the "territorial principle" (jus soli), and rights are only protected if the plant is registered in the place of sale. In other words, cultivating and selling a variety in a country where it is not yet registered does not constitute an infringement.
然而品種權採「屬地主義」，需在販售當地登記才有效，換句話說，在其他未登記品種權的國家栽植販售，便不構成侵權。
