If those ideas were specific enough, sooper, this wouldn't be as much of a problem.
For instance, the gesture to open the lock screen? that's NOT EVEN CLOSE to the iPhone lock screen. It's laughably different.
It's the fact that there is _A_ gesture to open the lock screen that is being sued over. The stock Android lock screen is even more like the iPhone lock screen than that.
This is a lawsuit involving 20+ attempted details to build a case. I'd bet that nowhere NEAR all 20 of those will wind up being a "success" for Apple, and they'll get some money back for the ones that they do win.
It's the classic game. Sue for A, B, C, D, E, F, G. The accused says OK - Prove A, B, C, D, E, F, G. The accuser says, okay A for this reason (demonstrates), B for this reason (etc), and the details are hashed out.
The 20 patents that are being sued over will not likely all turn out in Apple's favor. It's how most lawsuits like this are leveled. For Apple, it's also the principle of the matter.
