Plants Varieties, Its registration, and the Protection of Rights
IN BRIEF
Developers or breeders who invest in the plant variety development process should be legally protected. Under Thai law, protection is provided through the registration of new plant varieties (“NPV”) under the Plant Variety Protection Act, B.E. 2542 (1999) (“PVPA”). This aligns with the objectives of the PVPA, which aims to create an incentive by granting legal rights and protection to NPV.
