So why don't Apple license out its patents like MSFT?
Remember the Windows debacle? Apple licensed its Windows system to Microsoft for Windows vers1. Somehow the judge in the Apple Vs MSFT trial thought that license was valid for ALL windows system, not only for Windows 1.
Apple don't have a great track record in protecting its IPs and innovations. They have starting to try to do it the last couple of years but instead of the "look and feel" patent, go after the real patents. Apple have been awarded many multi touch patents that every Android phone is breaking. Go after them for this.
And please Apple: Stop supporting Samsung. Only reason why Samsung can copy you stuff is because they make a huge part of them. Lets say that Samsung manufactures the SoC in Ipad3, this means that Samsung have known for at least 4 month exactly what Ipad3 is. Thats why they can clone the stuff so fast, since they have Apples roadmap.
Apple needs its own foundry. They are big enough today to have one. Produce their own SoC + Flash memory = cheaper, faster and more secrecy. More risky, yes, but the upside is huge. Using their own A class SoC have given them a huge edge over Android vendors since its cheaper and no other SoC is in its class and its tailor made for Apple.
