Think you're being a little too apologetic for Samsung here.
I do think Apple used its design patents a bit overzealously, but look at it this way: it took a global lawsuit campaign to get Samsung to consider truly original ideas (notice the huge break in hardware and software layouts when the Galaxy S III came around). It would have otherwise been willing to take most of its design direction from Apple. The company is actually stronger because it has to think for itself
well, mostly.
If you want another example of Samsung's problem, look at the original Galaxy Tab 10.1. When it was unveiled at Mobile World Congress in February 2011, it was relatively thick with a pronounced rear curve. Days later, Apple unveiled the iPad 2; Samsung reacted by saying it "would not be outdone" by the iPad. Move forward five weeks, and the Galaxy Tab 10.1 was reintroduced at CTIA with a completely different, much thinner design
that looked considerably more like an iPad 2. At trial, Samsung lied and claimed that the redesign was due to other competitors who were at MWC, but the only other major rivals at that show were the Motorola Xoom and LG G-Slate, neither of which was significantly thinner than the original Tab 10.1 design (the G-Slate was only lighter because it was smaller). Anyone who wasn't a Samsung lawyer could see the iPad envy from a mile away.
That's the rub. Samsung's issue in 2010-2011 wasn't that it was making things look "a little too much" like a competitor's product, or using some kind of inevitable hardware design. This was overt, completely avoidable copying; phones from HTC, LG, Motorola, Sony and just about everyone else didn't look like the iPhone
but Samsung's did. Apple didn't sue those others over design patents.
