Theres nothing wrong with protecting your a patent for something you invented. There is something wrong with exploiting the broken patent system, to patent rediculous things like a square with rounded corners. It would be like Ford sueing Chevy because they use round wheels made of rubber. Or Coke sueing Pepsi, because they use pop cans also, that are both rounded with bevelled edges and a pop top. It's rediculous, and more a problem of our broken patent system.....
BUT what makes it extremely shady on Apples part, is that apple wasn't the first one to invent these things anyways. Other companies were doing this long before Apple. Rectangle devices with rounded corners existed long before the Iphone. Apple ripped off Xerox's GUI, and stole multitouch, pinch/tap to zoom, etc, that were developed by others, years before iphone even existed. Iphone stole these open source ideas, because they arent something that should be patentable, but they stole the ideas and dumped the money to patent them. I'm sorry but Apple did not invent these things. They just copied it from someone else, and then patent trolled it. Yet if someone else uses ideas from Xerox or one of those devices that were around long before iphone, Apple sues them. You may be blinded by the fanboism, but Apple is a monopolistic predator company who steals others ideas and tries to act all cutting edge as if they invented everything, when they are nothing but thiefs who play holier than thou. I would never give Apple a dime for any of their locked down idiotproof garbage.
