Apple did not "invent" the capacitive touch screen phone. When the iPhone first came out, it was not even a smartphone, it was a feature phone, and it wasn't the first one with a capacitive touch screen. It became a smartphone later in it's life when the App store came out, but it wasn't the first touch screen smartphone, and as was mentioned already, they weren't the first to come out with a multi-touch device. Apple pioneered the interaction with the interface, they made it finger friendly by using gestures that were familiar, and brought it together with the capacitive screen. That was their contribution to the industry.
The patent abuse by the tech industry, not just Apple, is ridiculous. It doesn't spur innovation, it spurs litigation. Companies focus their time on gathering up massive patent portfolios, and many of the patents are on things that they won't even bring to market. Then they just demand ridiculous licensing or sue the crap out of competitors, forcing the little guys to not even bother competing. Sure, people point to Microsoft and say "look, they have a totally new UI", which is ironic, since the icon grid Apple used in part to attack Samsung was made ubiquitous by Windows. Still, it isn't just the UI, it's the patents on generic gestures, features, and "methods" that irk the hell out of me.
Anyway, the penalty does not fit the crime. A number of the phones in the suit were carried by carriers who do/did not offer the iPhone, and many people preferred an Android phone to an iPhone because they liked the OS, or were looking for something in a lower price point. If Samsung has an argument to make to get the verdict tossed, it's that the penalty is unreasonably high considering the availability of the devices in question when placed next to the iPhone. Remember, the amount was supposed to reflect moneys lost to the infringing devices. In many cases, if the infringing devices didn't exist, the money would've went to another, potentially Android, handset.
Also, FWIW, I had a Samsung Fascinate, and one of my biggest gripes with it was it looked too "iPhoney", so I can certainly see why Samsung was dinged for it (I purchased it for the display, size, and thinness). I even mentioned it to friends. Whether or not Apple had the design idea first, or whether Samsung had a basic idea on paper before the iPhone came out is a different story. I would've preferred Samsung not aim the Galaxy S series and Touchwiz at the iPhone as a design benchmark.
