Perhaps this is off-topic, but I remember giving OS X a test run when it first came out and a lot of the 'new' features and gimmicks resembled those already available in many open source desktop environments like Gnome, KDE and other free environments and widgets. Do these open source developers have any recourse?
Another thing: How can you patent icons? They are nothing more than miniature images. The transitions used also existed previously on the desktop environments mentioned above, way before Apple got into the game of using a *nix-based operating system.
