The really funny part is that 50 years ago Congress rewrote the law to say exactly what the Court said today, which was already the precedent under the old law. So 100+ years ago Congress wrote the law in an unclear way, the Court clarified, and then 50 years ago Congress fixed the law to say the same thing as the precedent. Then a couple years ago, the appeals court made up some nonsense that was exactly the same as what the Court had thrown out 100 years ago. Most slashdot readers are on one side or the other of this issue, and either way, they don't/won't/can't comprehend the basic facts in dispute.
The whole thing is only a few pages, and it was written by Sotomayor so it is easy to read. They upheld the exact wording of the statute here, which is in agreement with precedent. The only thing thrown out was the awful ruling.
The Federal Circuit would have us believe that the word "article" in "article of manufacture" means only things available for sale by themselves. As Justice Sotomayor explains, article actually means any item, it is a very broad word. So an "article of manufacture" is a thing you make; the definition has nothing to do with if it is sold to the end consumer in a single box or not. According to Apple and the Federal Circuit, even the toys in a Happy Meal wouldn't be articles of manufacture, since they're not sold by themselves! A toy in a crackerjack box? Not an article of manufacture. A car stereo? Oh, only if it is a brand available in the store. A brand only sold as an OEM unit would not be an article of manufacture! Complete absurdity.
Also clear in the ruling is that if Samsung had had better SCOTUS lawyers, they could have got more of the issues decided; there were issues briefed by the government that would likely have gone Samsung's way, that are instead being sent back down to the Federal Circuit. But the Court did make clear that they're ready to do more work on this case when it comes back, and it likely will because Apple can't resist asking for the moon, and the Federal Circuit can't resist giving Apple whatever they ask for.
