Daniel B. Ravicher from PUBPAT did a great talk about the patent system and more importantly, how it doesn't work. Worth watching if you are in the tech industry and if you're interested in the subject.
The PUBPAT's mission statement: "PUBPAT Represents the Public's Interests Against Undeserved Patents and Unsound Patent Policy". Their website could be a bit more glamorous and less dry, but it is an important cause that affects all of us.
A really great speech, I had no idea patents were not properties but actually just grants from the Government!
