A 'new' variety of rice was patented by a foreign company, though such varieties have been present in India for a long time. This is related to Co-667, Basmati, Sharbati Sonora, Lerma Rojo?

The US government granted a patent for Indian Basmati to the company “Rice tech”. The government of India challenged on April 28 2001. Consequently United States Patent and Trademark Office sent a notice to rice tech for amendments in their claims and the patent was eventually cancelled. So, the correct answer is Basmati.
