JJ points us to the latest in a long list of examples of how patents are being used not to "promote the progress" but to actively hinder it. In this case, bioengineering companies are using intellectual property claims to stop academic researchers from doing any research
on genetically modified seeds and crops. Even though the seeds can be bought, the companies are using IP rights to put in place ridiculous licensing agreements that forbid any research on those seeds or the crops that come out of them. A group of scientists are now complaining about this to the EPA, but perhaps they should be complaining to the USPTO and Congress, as well, as it's time that this sort of abuse of intellectual property was stopped entirely.
