1970 the United States followed the lead of seventeen Western European nations and passed the Plant Variety Protection Act 1970 (US). This legislation provided protection to developers of novel, sexually reproduced plants. However, the United States originally acceded to the UPOV Convention on the basis of the Plant Patent Act and did not bring the PVP Act into compliance with UPOV requirements until 1984 when the Commissioner of Plant Variety Protection promulgated rules to do so. Since the 1980s, the US Patent Office has granted patents on plants, including plant varieties this provides a second way of protecting plant varieties in the United States. Australia passed the Plant Variety Protection Act 1987 (Cth) and the Plant Breeders Rights Act 1994 (Cth). Australian patent law also permits the patenting of plant varieties. In total, 65 countries have signed the UPOV Convention and adopted plant breeders' rights legislation consistent with the requirements of the convention. The WTO's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) requires member states to provide protection for plant varieties either by patents or by an effective sui generis (stand alone) system, or a combination of the two. Most countries meet this requirement through UPOV Convention-compliant legislation. India has adopted a plant breeders' rights law that has been rejected by the UPOV Council as not meeting the requirements of the treaty. The most recent 1991 UPOV convention established several restrictions upon international plant breeders' rights. While the current legislature of the convention recognizes novel varieties of plants as intellectual property, laws were formed concerning the preservation of seeds for future plantation, such that the need to buy seeds to use in subsequent planting seasons would be significantly reduced, and even potentially eliminated altogether. In addition, the 1991 convention also concerns the method of instigating plant breeding by implementing pre-existing and patented plant species as contributor of vital genetic information in the creation of what would legally be regarded as a new variety of plant. Constituent countries of the World Trade Organization are required to acknowledge the creation of new varieties of plants, and to uphold these creations within full recognition of intellectual property rights laws. A formalized legislature, exemplifying the manner in which such intellectual property rights can be conferred, is demonstrated by the 1991 UPOV convention, which declares such rights upon an individual breeder. This document further identifies a breeder as one who has found or
