I just read the funniest story (link below). Apparently someone gave a company a patent on using images as links  or pretty much any media. They are sending invoices to companies and people that have web sites and asking them to pay up. I took a class about patents when I was in college and I distinctly remember the rules saying that in order to be granted a patent the product has to be something unique and innovative. What in the world is innovative about linking from an image?
