This was my post from another thread on the safety of GM (genetically modified) food. To me, patent laws are much more dangerous to our food supply than the food itself. If I buy a genetically modified plant, the company who sold it to me retains patent rights over the plant, including the seeds. So, I'd be infringing on the patent to take the seeds from the previous year's crop to start a new crop. It gets even more confusing when the genetically modified gene becomes so prevalent that the vast majority of any one crop has this genetic modification. Then, the patent company could theoretically go after any farmer it wanted. This is not a hypothetical situation, by the way. Such a case is making its way through the legal system right now. Here is a Wired article about the case: http://www.wired.com/wiredscience/2012/04/arstechnica-agriculture-patents/ To summarize, a farmer just bought random commodity soybeans from the market and planted them, and he was sued. The farmer lost his case in district court, and the Supreme Court agreed last month to hear it: http://m.npr.org/news/Technology/162949288 I hope the Supreme Court realizes that a company cannot claim a patent on ALL the generic soybeans in the state. This is a frightening prospect.
