How can monopoly patents threaten food security and the livelihoods of farmers? The controversial Enola bean patent demonstrates the abuses of intellectual property monopoly:
A US patent on a yellow bean variety has disrupted export markets for Mexican bean growers and is now wreaking havoc on small farmers and seed companies in the United States. The patent makes it illegal for unlicensed users in the United States to grow, sell, import, or use the proprietary yellow bean seeds.
Larry Proctor, the president of Pod-Ners seed company (Colorado, USA) and the owner of the controversial US patent on a yellow-colored bean variety, filed a lawsuit on 30 November 2001 against 16 small bean seed companies and farmers in Colorado, claiming that they are violating the patent by illegally growing and selling his yellow "Enola" bean. Proctor holds both a US Patent and a US Plant Variety Protection certificate on the Enola yellow bean.
