The most ludicrous part of all of this is that you can patent biology.
These beans wouldn't naturally exist if it weren't for Monsanto. It would be extremely difficult to produce a soy bean that didn't produce seeds... since that's the bean part.
This is very different from the Myriad BRCA1 patent where they patented a naturally occurring mutation in humans. In Monsanto's case, they actually produced something that was novel - an herbicide resistant soy bean.
