Several more patents have been awarded that are quite important:
Unfortunately I have to agree. I am definitely an Apple Fan Girl, but Nokia does hold necessary patents.
I believe the main issue is "Fair, Reasonable and Non-discriminatory " royalties for the patents that were adopted as the in the "Wireless Standard". Nokia was given a monopoly in exchange for agreeing to "FRAND" royalties.
Apple has been in business for about 3 decades and has built all sorts of devices including the Newton, laptops, displays, input devices, etc. All of these could potentially hold patents that Nokia is infringing on. It really ends up being an "everybody loses" situation. At worst, Nokia could be exposing themselves to wiping out the entire company on patents they're infringing on. It's best for everyone to say that nobody owes anyone money and drop the matter entirely. Many companies share patents for the purpose of avoiding costly litigation that harms both parties.
