Good analogy - although I'd quibble with the description of "stolen" (some Chinese manufacturers excepted - see Top Gear China special). Look at Cadillac for one, and Mercedes Benz for another (http://en.wikipedia.org/wiki/Mercedes-Benz#Innovations)
And therein lies the difference - as you rightly say - generally speaking the motor industry places a premium on being first to do something, others are free to follow, albeit at the risk of being labelled a "follower" rather than an "innovator". I also read of circumstances where patents a company holds are freely licensed to competitors - c.f. Apple's "cease and desist" mentality.
I'm not anti-Apple, but I'll agree with your "go for what's best" comment. E.g. in my case iPhone and iPad are too restrictive, but I've got an iPod Nano because that's better than the competition in the market (although there's some new Sony devices that look very promising).
Getting back to the article - shame Sony didn't volunteer to be a "friend of court" and testify in support of Samsung. As I've said before - it's going to be beneficial for consumers for Apple to lose this case, and lose it big.
