A biological patent is a legal document that grants the patent holder the right to prevent others from using, selling, creating, or importing the protected invention for a set period.
Since a product may be simply copied by anybody once it is on the market.
Consequently, patent protection is necessary to prevent duplication.
Examples:
1. Neem:
The European Patent Office (EPO) dismissed WR Grace's appeal against a decision it issued in May 2000 maintaining India's argument that the therapeutic plant was a part of Indian folklore.
USDA and WR Grace received a patent from EPO in 1994 for neem-based biopesticides used on food crops.
2. Basmati rice:
In 1997, an American business obtained patent protection for Basmati rice from the US Patent and Trademark Office, enabling it to market a "new" type of Basmati both domestically and internationally.
This brand-new Basmati variant was created using Indian farmer's variations.
Semi-dwarf cultivars of Indian Basmati were crossed, and the result was marketed as a creation or novelty.
