The question isn't whether samsung decided to build iphone-like phones. Everyone can see that they did, the galaxy devices look way too similar. The question is whether they directly copied it, and apple has legal protection. I don't think they do. I don't think you can claim that samsung directly copied the iphone, either in general or in specifics.
First, in general. Did apple invent the "all touch" category? No. The earliest all-touch smartphone with on-screen keyboard is IBM's Simon, from 1992: http://en.wikipedia.org/wiki/IBM_Simon . Did Apple then invent finger-friendly glossy UI's with capacitive touch screens? No. See for example the LG KE850 (prada phone), which was first demoed a year before the iphone: http://www.oopshi.nl/images/ke850-prada-oopshi-nl.jpg . Note that LG threatened to sue Apple for copying the prada phone's design: http://www.applematters.com/article/the-iphone-lawsuits/
The iphone's grid layout that launches apps is merely an evolution in a long history, starting at the newton, through palm, back to apple: http://www.applegazette.com/wp-content/uploads/2007/06/inter... . I used to have a palmpilot pro, and you can clearly tell that the iphone's designers learned a lot from that UI. So, when talking about the general design, there's nothing in there that originated in the iphone. So, if there's nothing that apple can claim ownership on in the general case, let's look at specifics.
Apple isn't suing for the general UI design, because they learned early on that it isn't protected when they tried the same thing to protect the mac interface (which they themselves copied from Xerox): http://en.wikipedia.org/wiki/Apple_Computer,_Inc._v._Microso... . Instead they're suing for the distinctive design of the icons on the iphone. And, well, I don't think they're copied. Inspired by, yes, but direct copies they are not: http://static2.businessinsider.com/image/4dadf745ccd1d5aa3f1... .
If anything can be learned from all of this it's that history is written by the winners, and that everyone stands on the shoulders of giants. If it were me, I'd do away with patents entirely. No point to them really, not if you look at how preciously little there is that's actually original in any innovative product.
