Only in magical HN land do companies "scramble" to address issues like this. The best thing to do is to pretend these companies don't exist and you've never heard of them, their patents, or what they're up to.

Once your patent lawyers have had time to study what's going on, then you're ready to do something.

It's not "disturbing" at all. It's just common sense.

Yes. It is quite possible that Apple's patent lawyers are scrambling. It's just that scramble-speed in legal land is weeks, not hours.

Lawyers can read and write at superhuman speed, but it still takes time to prepare all that material and do all that research. It's not a field that rewards those who shoot from the hip.

I'm looking at more from a developer relations standpoint - I would think every developer who's got one of these letters is wondering where Apple is and why they haven't handled it already.
