Buying out all patents related to something up and coming sounds dangerous, we already dislike submarine patents and this sort of act could make them even more likely.
It's not dangerous if they are all opened up - completely the opposite. That's what Google did with buying On2 and opening up VP8. That is really useful way to spend extra cash - it benefits everyone.
Not really. Since there is no guarantee the same thing will happen with any other given patent. It's not like each patent has a great value. The ones which affect the critical markets are important. But trolls already push for making such patents to extort money so it doesn't really change the incentive for making more of them. Was there any higher patent rush after Google bought On2?
I think it does - it creates interoperability for video on the Web. It benefits everyone including Apple. But they don't think in such terms or pretend that its not relevant. And anyway - they should profit from creating technology, and not from sitting on the pile of patents. But Apple is Apple.
