Right of Priority for Foreign Plant Breeders
Note:
Foreign plant breeders have the right to claim priority in asexually reproduced plants under U.S. patent law since 1930.

Insofar as the patenting of asexually reproduced plants in the United States is concerned, both national treatment and the right of priority have been accorded to foreign plant breeders since enactment of the plant patent law in 1930 (now 35 U.S.C. 161 – 164). See MPEP § 1613 for the right of priority based upon an application for plant breeder’s rights.
