Samsung doesn't implement the slide to unlock action on a predetermined path. On 2012 phones, it's just swipe anywhere along any direction for a certain distance. IIRC, onn the 2011 phones it was slide the lockscreen wallpaper in any direction.
I was not trying to give a total judgement on the case but argue against the claim that all the patents were ridiculously broad (admittedly the data detectors one looks very broad to me although if read in the broad way MUST have prior art).
It is clear that at least at the time of grant that it wasn't the only obvious way to unlock a touchscreen - it wasn't used by MS/Palm/Ericsson. Prior art from others may apply but the fact that many weren't doing this indicates that it wasn't completely obvious.
The scope is highly limited and no one needs to practice them at all. There are still issues of accidental infringement and the high costs of defending actions particularly in the US. However you could just wait until challenged on issues of this type and then workaround removing the incentive to prosecute an action against SME's.
To take your analagy it is more like the rough surface of a newly paved road than potholes.
Its right up there with someone trying to patent the ESC key.
