Nokia is being very modest saying only TEN patents involved. I would think over a thousand patents that were infringed. The proof is in proving this which should not be difficult because the patents are global filed in countries that matter (in law and enforceable, except in China probably).
The more Apple fights, the higher the price it will escalate. I guess between $1B and $2B for starters plus additional royalties per unit there after. Yes, it will make the future iPhone higher price but does that realy matter to the fan base ?. hardly. what is a few dollars more ?.
Nokia is just the "gatekeeper", the real giant is Ericsson and they even have more patents than Nokia and Qualcomm put together. I want to see that "battle of the giants" confrontation. Ericsson will have a new CEO next year, so he might want to make a name for himself.
