I keep going back and forth on whether the patent wars going on in IT are ridiculous or not.
On the one hand, patents are supposed to be awarded for things that are novel, useful, and non-obvious. It seems that a lot of patents fail the "non-obvious" test, and more than a few are being awarded for things that are not novel. I'm especially skeptical about the idea of software patents. And there's no doubt that patents, which are supposed to be used to spur invention by giving people the ability to profit from their inventions, can also be used as a blunt instrument to prevent other people from competing.
And don't even get me started on patents for things that are necessary industry standards. Seems to me that if a company submits something as an industry standard, they should relinquish their patent on it.
On the other hand, I look at the way cell phones used to be before the iPhone. We had an amazing range of radically different cell phones in all kinds of different form factors. Flip phones. Those cool slider phones they used in The Matrix. Phones that unfolded vertically.
Nowadays, nearly all smart phones have the same form factor and look the same, right down to the rounded corners. Samsung phones, the HTC Sensation in my pocket, LG phones...with the exception of BlackBerries, they all look pretty much the same. That tells me that yes, people really are copying Apple; it's not like a smart phone HAS to have that form factor!
