The internet has a few kinds of links, but the most common are text and image links. For example, I can link this image of VueStar’s logo:
To a website featuring stuff on a cat (luckily I’m in a good mood or you guys would have been in for a surprise). It’s one of the backbones of our freedom. Sadly, a Singapore firm,VueStar, patented a system for “Method of locating web-pages by utilising visual images”, which is kind of like creating a patent to identify a goat on sight. Obviously this “patent” has implications in Web 2.0 because soon those curved buttons and image reflections might cost you a visit from Vuestar’s lawyers.
